Green Poop: The Implications Of Food Dye On Poop Color

l 100+ pointsm 1+ points - Newb

Editor's note: here's the short answer -- blue food coloring turns your poop green. Keep reading to find out more, and then peruse the many, many comments for corroboration.

Since my freshman year in college (a small liberal arts college in
northern Vermont), I've been fascinated with the correlation between the ingestion of
food-coloring and the color of the poop produced. Lest you think I'm fabricating, here's the background:

The year was 1996. I was a biochem major at St. Michael's College in Winooski, Vermont.
I had consumed copious quantities of Purplesaurus Rex
Kool-aid in a one night time frame. A few hours later, I pooped. It was
green. Bright green. I was fascinated, and called as many of my
floor-mates as would come into the stall to marvel at the miracle of the
"not brown, not bloody shit".

I was a bit of a celeb for a while, until others replicated my
"experiment". Similar results ensued, with me being notified of each event
via e-mail. So, a craze started.

As the progenitor of the new species of poo, I was caught in the middle. Research spread far and wide; of
a campus of 2700 students, I was receiving up to 45 e-mails a day from

Anyway, enough drivel. Here's the science:

The dye used in purplesaurus Rex is FDA Blue #5, and dye-lake
red. Turns out that when metabolized in sufficient quantity, the blue dye combines
with bile, and forms a brilliant green. The red, absorbing at a 595nm
spectrum, is harmlessly eliminated.

What matters is quantity. I consumed 6
liters of the Kool-aid in the night in question (sans alcohol, that comes
later). I set up a study in the dorm, with people consuming anywhere from
(1) 250mL glass of the stuff (approximately (1) 8oz glass) to the maximum tested
so far, 6L. The experiment was structured on a single-blind study (won't get FDA
approval, but sufficient), with only myself knowing what each was consuming.

How did the experiment come into being, you might ask? Well, I campaigned for 24 "volunteers"
(the first consuming 1 glass, the last consuming 24 glasses). How did they
not know what they were drinking? Well, since it was only single-blind,
they essentially did -- though all were required to drink 6L of fluid total,
and ordered not to defecate at all in the 6 hours of the experiment.

Example: Subject 1 received 250mL of the subjected test substance, and
5.75L of water. Subject 2 received 500mL of the stuff and 5.5L of water.

Everyone was agreeable at first, but soon dissention reigned prime. But order
was maintained. After 6 hours, orders were given to poop, supervised (more or less).
Since I had unrestricted access to the chem and bio labs, samples of each
"extrusion" were taken, in the amount of 2g.

The results were heartening. I plan on getting a PhD (which, in this instance would probably mean, "PUSH
HARDER, DUMMY!") on this someday, so I won't post my final data, just enough
to give an idea:

  • Subject 1: 250mL Purplesaurus Rex with 5750mL water:

    Stool, firm and brown. Spectrophotometer reading: normal.

  • Subject 12: 3000mL Purplesaurus Rex with 3000mL water:

    Stool, firm(ish) and green(ish). Spec reading 550nm (definitely Green...just not GREEN)
  • Subject 24: 6000mL Purplesaurus Rex with 0mL water:

    Stool, Firm(ish) and
    Green, resplendent of original test subject (me). Spec reading, 535nm. Definition of GREEN confirmed.

  • Further experiments considered fruit punch (mostly synthetic, only 2.5%
    fruit juice), Hi-C of various persuasions, and various and sundry other
    store-bought concoctions.

    If you're interested in my results, let me know...I'll gladly share them for
    the good of society.

    On May 27 2003, received this email. Dave J, the author of the above piece, was so happy that he wanted this added to his story as proof that writing for PoopReport can improve people's lives.

    dear poopreport,

    i know you may find this hard to believe, but you just eased my mind tremendously about our daughter's "poop situation." beginning yesterday about 5p.m. our daughter began having bright green dirty diapers. she has had four in a 24 hour period and i (being an over paranoid mom) have contacted everyone i know, including our pediatrician, and no one had any answers other than it will probably go away. that response just does not cut it with me. i had to have answers. i have been on-line non-stop trying to dig up a possible answer. i told our doctor that the only new food or drink she had consumed was "purple kool-aid" and lots of it. he told me that purple kool aid would not produce green stool. after reading your article i realize it can. thank you soooo much. after hours of searching and worrying, i am off to bed.

    -- grateful mom

    I encourage all PoopReports to drink copious amounts of Kool-Aid this Fourth of July weekend, and report back your results. We should attempt to mimic Dave J's experiment as closely as possible... so try for at least 3000 ml (that's roughly 3/4th of a gallon) of Kool-Aid along with a similar amount of water, or, if you're a real trooper, 6000 ml (1.5 gallons).

    Even if you don't stick quite to the way Dave J prescribed it, please report back on your findings.

    Brown Seymour's picture

    Wouldn't it be easier to just eat packets of the powder? Or make a sludge using a small amount of water, so as to chug 10 packets at once? I think that would be the most expedient route to some seriously green poop.

    Oh, if folks could snap a polaroid of their bright green poop and post it, that would just be super.

    Brown -- you may have a point with the powder. In the name of scientific inquiry, I suggest you try it.

    Brown- I'd toyed with that idea...however, I wasn't sure how the dyes would be metabolized in the absence of sufficient water (i.e. the way I first consumed it). If it takes a lot of water for the enzymes in question to do their "doody", the results of your hypothesis might be disheartening. Who knows tho? Since I'm in the real world now, and don't have immediate access to 24 dim-witted willing college drogs, I'm at a bit of an impass in my research. I'll provide consultation with anyone who wants to pursue it tho!

    Hey Dave J, this was a Kool experiment. It's interesting that it was real easy to get volunteers. How did you stop a dude from taking a dump mid-experiment? Also, how did you supervise these dudes when they took a dump? Did they shit in the toilet or did they shit into containers so that you could collect your specimens?

    my poop is green anyways

    I am constipated. I havent taken a healthy poop in over a year. I do not drink enough water.

    Justus Loonz's picture

    I like both of Brown's ideas. Eat the powder and consume a minimum amount of water. Then take a pic of the freshly spawn grogan for the masses. If I do this in the next week or two, I'll go to UseNet and post the pics in then take plenty of antacids. The subject line I will use is "green green grogans of home." and hopefully the digicam will do it justice.

    Mike- Good comments. It wasn't hard to get volunteers; after all, it's an all-guys floor...if you were a shameful shitter, you'd probably die. I delegated supervisory roles to my roommate and my neighbor. They didn't actually "witness the birth", but they made sure there wasn't anything funky going on (auxillary food dye, etc). The collection was handled by swabbing a long q-tip into the loaf, the tip of which was then placed into a microfuge tube, and the handle snapped off. That was done by the poop creator. It wasn't hard to prevent mid-experiment dumps; I just asked them not to, but if they absolutly had to, then they had to write down the time of the dump. The purging took place about an hour after the experiment ended; since the dye is soluable in water, it didn't have to pass all the way through the colon; most of it was absorbed in the ascending colon, and sent directly to the liver and kidneys.

    Hope that helped!

    my wife had a childhood memory of her favorite cereal, Boo Berry which i am sure many of you all remember. she seemed obsessed with this cereal and wanted to find it and eat it again, this proved to be difficult due to the limited market of Boo Berry , it seems that you can only find in select stores nation wide because most stores wont stock it for some unknown reason. well i found that it could be purchased online and shipped to your door so i ordered 4 boxes...the smallest amount you can order. it arrived and i must admit it is very very tasty. well we ate all 4 boxes in a matter of 2 days, this was a mistake! after about 3 days i had my first in a series of about 8 glowing green shits that smelled absolutly HORRIBLE!! our one bedroom one bath apartment was borderline unliveable for almost 3 days.

    just thought that this might help warn any unsuspecting people out there about the ghost shits also could prompt a new study??

    KMM's picture

    Hey anyone can change thier poo colors ;) I make ramen noodles with food dye in it and eat that stuff all the time I get loads of different colors =] just letting you know =-P

    Sputtering Dudly's picture

    Other colors that I know how to make are...

    Orange, make sludge with Generic Tang then drink way to much

    Purple/Blue Some slushpuppie flavors with extreme sauce added have had amazing effects on people I know

    Geronimo!!'s picture

    In one of my biochem/nutrition classes my prof mentioned a dye used for fecal energy testing - I can't remember what it's called but it had the same effect - BRIGHT GREEN - if you're a bchem guy, what was it called? It's banned now for use in humans (thank god, my prof used it on himself and he's got issues) but it is still used in ruminant testing - any ideas?

    Dave (the author)'s picture

    Geronimo- It could be methyl blue- that stuff is also used extensively in urinalysis, but since it comes out in your pee, I'm not positive it'll retain in the colon. Another option might be bromothymol blue, but I'm pretty sure it's always been known to be toxic...might be wrong!

    I have found that Red Velvet cake mix will cause a quite brilliant neon red poop. I was quite surprised the evening after I consumed 2 peices of this cake. The dye is incredibly strong and took me several cycles before it went back to normal color.

    Jolene's picture

    I just went poop and when i wiped i realized that my poop was green. I couldn't understand why since i couldn't recall eating anything that would do that so i got a little nervous and decided to get online and see if i could find any possible explination. I came across your site and realized that the strawbeerry kool-aid i have been drinking was more than likely the culprit. so thanks to your experiment i know that the only thing wrong with me is the beverage i have been consuming.

    anon's picture

    Ditto last comment. Found that it was green. Went online. What I had was a couple of packs of grape bubble gum in 3 days. It was bubbilicious. Apparently they use blue food coloring.

    I, too, have used Kool Aid to turn my poop colors. I go now to type my story - I will call it "Me and Darin and the Blue Poop" and I will submit it to this site for posting. Perhaps it will be funny.

    What a website! I thought I was the only one contemplating poop colors and pooping's affect on health! Great job! I'll be checking in again. btw,as serious as this topic is, I'm falling out my chair, laughing...think I might poop!

    If you want green poop, go to a sonic drive in and drink a 44oz blue coconut slush. You'll be shitting green for 2 days...

    Julie's picture

    I ate Extreme Berry Sherbert from Baskin Robins last night, and today, almost fell into the toilet after I wiped, and noticed a bright green line on the toilet paper. I got up to investigate further, and oh my god, it looked like I'd shit out little clumps of grass clippings.... pure green. Of course curiosity (and wondering if I was dying) got the better of me, and I logged onto yahoo and typed in "green poop" and thankfully this page pops up.... Now I don't feel like such a weirdo after reading all the above posts!!

    Dana Rosen's picture

    You guys should try the "Ocean Water" fountain drink from Sonic Drive-In. It is a mixture of Sprite, Blue Coconut flavored syrup and crushed ice. The result is neon green. NEON GREEN! Nothing like looking in the toilet at 3 AM and seeing neon green stool. As Julie had explained in her post - "wondering if I was drying" I consulted a nurse friend and was reassured it was all cool and a result of the food coloring used in the Blue Coconut syrup. Oy Vey! Once the initial shock of neon waste wears off it becomes pretty cool.

    Amy's picture

    I have experienced the green poo! The only thing I can think of that caused it is the mango sorbet I have been eating these past few days. It is only thing I've eaten with food coloring in it, so, evidently the green poo can come from many different colored sources.

    Gordon's picture

    My doctor has confirmed in the past that my iron supplements when not digesting properly were the cause of my greep poop. Switching form a tablet to liquid form resolved this issue for me. Again - obviously green poop can come from many sources!

    The Bunger Sisters's picture

    I noticed the same phenomenon--neon-green shit--when I drank tons and tons of Grape Kool-Aid. None of the other flavors had any effect on my bung hue, just the blue dye in the grape-flavored variety.

    Had a friend, a female, who drank tons of "Hot Damn" (cinnamon schnapps) at a frat party one night, came home at the end of the night, and shat bright red. She thought at first it was blood, and that in her drunken stupor, was inadvertently butt-plowed by a gang of frat boys. Even went to the hospital. Turned out it was the red dye in the liquor. True story!

    Big Boo's picture

    You didn't have to drink that massive quantity of Kool-Aid. You could have done like I did and eaten one of those extra big sugar cookies that had been decorated with blue, green and white frosting to make it look like a picture of the earth. A day after ingesting that little treat I was both shocked and fascinated to find that a neon glowing green shit in the toilet. I should have taken a picture.

    Beaux's picture

    Purple or blue liquids are not the only thing that will make your poop green. My fiance and I "discovered" that eating blue corn chips will result in kelly green stool. And a friend of ours ate an entire box of Boo Berry poop.

    The Soup Nazi's picture

    I've found that the Berry Luzianne Smoothies have produced green stools as well. I'm glad I ran across your site. Now if I can come up with some purple soup!

    Captain Asparagus's picture

    I've had my share of run-ins with green poo as well. One time that stands out in my mind occured some time in the early eighties after having consumed two or three bowls of "Smurf-Berry Crunch" cereal, which contained tiny balls of red and blue. Ever since then I have been on a mission to find a way that I can make a green fart cloud. If you have any suggestions I would appreciate them. Thanks.

    thank you so much for telling me why my fiance's poop has been green. He loved to drink koolaid all the time. He thought he had prostate cancer until we came to your website and new that nothing was wrong with him except for drinking excess amounts of koolaid. Thanks my pooper scooper!!!!

    Two more stool hue shifting delights. Blue cotton candy got me a couple of years ago, and my latest was with blue cake frosting. I ate so much cake frosting I got liguidy poo and changed the water green. When I wiped it looked like a grass stain on the toilet paper. Sheesh this site set my mind at I'm goona have some fun with it.

    My 6-year-old son picked the ice cream for my birthday celebration: Blue's Clues

    blue artificially colored vanilla ice cream.  We both have had a bowl in the afternoon for the past

    week and in case you didn't know, poop is a popular topic for 6-year-old boys. 

    We have been laughing at our crap all week.

    But alas... our week-long green poopfest is coming to an end. We finished the last of the Blue's Clues ice cream yesterday

    so today will be the last "greenie".

    I'll not get another 'till St. Paddy's Day.

    I saw a lovely neon green glow in the toilet bowel for the first time in my life today. It was totally freaking me out b/c i couldnt think of ANYTHING i ate or drank that was green. (including any type of pill, candy, or vitamins) By looking on this site, it MUST have been the "jagged edge" powerade i drank. It was a very deep purple, and it seems like grape/purple is the key to green stool =). It was easy to track down because i hadn't been eating or drinking much at all recently. Thanks for this site for saving me alot of worrying!

    I ate some of this ice cream at TCBY called African doo rag, it was like a blue rainbow color, I shat blue instead of green, it looked like playdough and I wanted to put it on a bun and eat it like a hotdog on the fourth of july. But of course I just admired the little fella and sent him to doo heaven.

    P-hole's picture

    The first time i went to the restroom today i saw that my poop was green. i was kind of weirded out by the whole sittuation so i wanted to know the cause. i haven't eaten any purple cool-aid today (although it sounds real good.) but as i read this i looked back and all i have eaten today was lucky charms, cheese sticks and a bacon egg and cheese pocket. I will now test it and see what is making it so green. Thanx Dave J.

    i'm siding with firechild on this one. i just blew a neon green one out- kinda scared me, hit the search engines, and BAM- i found my answer on this page. Damn Jagged Ice powerade

    You'll be happy to know that your copious research has eased another mind. I too noticed two green turds today and started searching the web for an answer. Turns out that I had two grape sodas (which I never drink) at my sister's house yesterday which surely contained the dreaded blue dye. I'll have to find out for sure and follow up.

    Green Pooper's picture

    I just had green poop! But I didn't drink Kool-Aid or anything blue/red. I thinkk it has to do with my intolerance to lactose. I've had a lot of those lactose-enzyme pills today. Mine wasn't lime green, it was more of a steamed spinach color. =)

    Dani's picture

    I had green (veggie green) poop today, and was a little worried. Because of this webpage, I figured out that it was the quart of Crystal Light Raspberry Tea that I drank last night. Thanks!

    kadath's picture

    Phew! That's a load of my mind! When I first entered the Army, the next day my poop was bright green. It gave credence in my view that they put stuff in that reception center chow. Good to know now that it was only probably a side effect of americana crap.

    Sexy McSex's picture

    Less talk about green crap, more talk about splattering the bowl, what the f*ck are these people thinking, I've got diahrea, the product is officially not a number two or a number one, yet not sitting on the seat seems a good idea so it goes all over the floor as well as splattering the bowl and then a quick exit to finish your Chicken Mcsandwich without flushing the toilet so we all no you're a smelly scuttery dirtbag, I've seen this, nearly puked my wonderful veggie burger and had to close my eyes and think of a happy place. these "events" though frightfull at the time do prove wonderfull pub talk and believe me everyones got a come on folks were all human, even the Queen does poos ya know, bye take care now.

    Golly gosh, just had and after thought, it was a sea of brown with no interuptions of white or maybe a pale peach even......this lady didn't wipe!!!!!!! No toilet paper, gosh I'm thinkin her pants must have gone on pretty smoothly after that!!!! God....sorry for the mental picture what can I say I'm an artiste!
    Bye folks, also other interesting topics, stuff you find in portaloos and why don't they make fake poos(that's what we call it in ireland ya know!) yeah anyway fake poos made of chocolate and you could give them as presents to people who really love chocolate and see how long they can resist on the cold dark nights when the've got a craving and no one wants to get up off their arse to go to the shop, of course hidding in the shadows with a camera whould not be a wasted couple of months, i can think of worse ways to get chronic cramp of the knees! tid be only hilarious!

    poopmasterflash's picture

    fierce grape gatorade can do it. so yo yall, im a nyc photographer interested in taking some photos of things that arent green crap... like for one thing, im doing a book on girls with hidden tatoos - so if you know anyone then get at me - and if its a tatoo of a peice of green poop, well thats even coola. holla!

    Jill's picture

    Coconut will do this too. I remember eating large amounts of sweetened, dried coconut when I was little (my mom use it for baking), and then having bright green poop afterwards. I always thought it was really funny.
    I'm in college, I'm sure I can find some friends to replicate the experiment. :)

    Belgand's picture

    I noticed a while back that for some odd reason my stool had adopted a green tone. The only reasonable cause (later confirmed by a repition of the same) was eating guacamole. Not exceedingly large quantities either, but some yummy fajitas with guacamole was all it took.

    Well now I know why my poop turns green and knowing is half the battle!

    Tito's picture

    I didn't bother reading through everything, so I don't know if anyone has mentioned this yet, but eating a lot of fruity pebbles will also cause your poop to turn green. Grape Gaitorade works as well, but it is getting hard to find (if they even make it anymore?).

    Scat-Kat's picture

    How come you call is poop? Are you scared of the word: shit, or isn't it allowed... and if that's the case, I think you've got more than the colour of your excrement to worry about.


    Ace Rockola's picture

    Well now I had a leprechaun myself a few weeks ago, but it didn't concern me enough to look online for the answer. Now I'm going to be wondering what I ate that week that had blue food coloring in it.

    Ever digested too much of the Tongue Splasher's gum? The dye in it will turn your poop weird colors, too.

    Anonymous Tandoori Eater's picture

    For all of you who want red poo: I used to marinate chicken in Tandoori paste. Hello, lovely brick-red poo ... for days. Beets will do it, too. But the most amazing multicolor poo I ever saw was after my son (then 18 months old) chowed down on an entire box of crayolas. (OK, the poop matrix was plain brown, but the little chunks of color were just as bright as could be. If I'd known the Purple Kool-aid trick, or the Tandoori Chicken trick, at the time, it would really have been impressively lovely -- confetti colors in a green or red matrix. Your readers are invited to try this. Crayolas are quite harmless. Chew them well, for best results!)

    Jim's picture

    Very interesting and amusiong topic. Thanks for the laugh. I don't think I saw this. One time when I had a nasty cold I drank an entire large (gallon or 2 gallon size) sized orange hi-c fruit drink. The next day I pooped green. It wasn't neon color, but it was definitely green. I also consumed a lot of vitamin C that day (like 2 excessivly sized tablets) so I figured the vitamin C mad it green. Now I know it may be the food color.

    Drew's picture

    Along similar lines, , I was once treated for a bladder infection and was prescribed (I think) 'pyridium' which caused my urine to appear neon, day-glow yellow, actually almost orange colored, and very very bright. I knew exactly where the splatter went! This was in the '70's and at O C fairgrounds Speedway motorbike races on friday nite and everyone was at least half drunk and a long communal urinal EVERYONE stopped (I mean cut it off!) when I started pissing, it was almost worth the pain to see them (and it)

    If you want seriously green poop drink one glass of the green 'Incredible Hulk' Hersey's Chocolate milk. Scared the crap out of me at first. No kidding.

    Awed Aunt's picture

    In her extreme youth (like age 1-2) my niece developed a craving for cigarette butts--no doubt an attempt to look like us cool smoking adults. She would steal them from ashtrays and stash them under the sofa cushions, then return when noone was looking and chow down. Talk about green poop! This was a nice grassy, organic green, well formed, a sign of high fiber content no doubt! God knows what it did to her insides!

    Hagrinas's picture

    When I took my small daughters to Baskin Robbins (a US ice cream chain store) they ordered some sort of rainbow sherbet. The advantage of feeding it to small children is one of proportion; a little goes a long way.

    The bottom line is that if you think a single die is interesting, you just haven't lived until you see what came out.

    I would suggest that you go to Baskin Robbins and get about a quart of this and consume it at once. It will be well worth it.

    The dye will do it, but doesn't all that sugar have something to do with it? I used to binge at the Krispy Kreme (I'm past that now), and I'd get green, runny poop.

    Poopie's picture

    OK, but what about pee. I'm sure everyone has experienced the bright neon yellow pee you can get from some types of vitamins.. but is there anyway to get green, blue or purple pee? That would be a neat trick.

    jozka's picture

    an ex girlfriend of mine, who once lived in pittsburgh (home of heinz ketchup) once told me she met a guy who worked at the company, and said the reason they came out with green ketchup, was because they originally tried blue ketchup, but it turned peoples' poop blue. oh shit! i totally would've bought blue ketchup just so it could turn my poop blue. a veritable goldmine...

    there i was dressed and ready to go to the gym when i decided it would be a good idea to go ahead and make a quick deposit to ensure when i was lifting no "little friends" came out...and whaddaya know i had the green poops. Scared to death i cancelled my workout and hopped online where i found my answer. I had been drinking Shasta Grape flavored soda and Welches grape soda by the gallon over the last few days...thanks for setting my mind at ease and letting me get back to my work out routine.

    Eat nothing but salad for three days and you will poop green. Take Pepto Bismol and your poop turns black. Eat a lot of stewed tomatoes and/or prunes and it turns red. Minestrone soup gives it technicolor chunks, but only if you get the nasty Campbell's kind.
    As far as pee colors goes, wakko, take vitamin B complex for a nice neon green shade. At least for a couple of days.

    Dude, I've been living in my dorm off of cap'n crunch... especially the "Oops... all berries" stuff...
    brilliant green dookie!
    It's really a sight... thanks for explaining, so that I didn't have to go home to mama and tell her her daughter shat green!

    I've had some nasty green and neon green shits before. Never really noted what caused them, but I know it was the food I'd eaten. Nice to know about the breaking down of food colors, should be easier to figure out from now on.

    I do, though, have a roommate who loves to talk about crap, literally. Being in our mid-20's it's still funny most of the time, but he can get a little out of hand. He especially likes to talk about the really dark, almost black ones that leave a stain in the bowl, usually swirling it's way down into the abyss. Yummy.

    Personally, the ones I don't like, but like talking about the most are the hiking piles. From way too many carbs, mostly sugars, to get a lot of calories, and burning it all off right away... peanut butter like smoking piles.

    The ones I don't like seeing, though, are after I've had too much salad or other vegetables and a really quick metabolism... sometimes it can be so undigested that I can tell what the food was beforehand, too.

    But now I'm lingering on too long, like the smell after a really labored dropping. Enjoy!

    this is a little off topic (still in the area of bodily excretions) but are there any non-harmful ways to turn urine colors? (stupid practical joke) as for fecus, what about colors other than green or red (just in time for the holidays tho!)? can one achieve white, black, gold, or even cobalt blue?

    For nature lovers, I have a possible all-natural version of this effect. I once went to a grateful dead show with no money and a bag of oranges. I ate oranges all afternoon, all night, and into the early morning hours. When I finally got home, I was perplexed by the bright green log I left in the bowl. I checked it several times to make sure that it wasn't just the after-effects of the grateful dead show.

    I ate a large box of Boo Berry cereal once, and pooped a bright blue turd.

    BLUE GATORADE - I think that was the catalyst for my girlfriend's 3 year old's green poo. She was freaking out about how bright green it was. I went to the Gatorade website and sent an e-mail to ask the dreaded green-poo question. I can't wait for their response. Maybe I should sue for emotional damage and force them to put a warning label on the product. WARNING - drinking excess amounts of Gatorade may cause a toxic green hue in your feces. HHHmmmmm now that I think about it, Gatorade can market this fun and intriguing experiment. Something like - try to get the colors of the rainbow in one single poo and you win a big cash prize.

    Drank some FIERCE Gatorade Grape Flavored and deposited the loveliest and smelliest green poo I have seen in quite some time. The good thing is that my nose hairs quickly dissolved from the putrid smell so I saved some grooming time to boot! Three Cheers For Green Poo! Hip Hip.....

    Okay, here's an update for your poop report... TGIF (the ice cream store) makes a blue ice cream that makes your face and tongue blue, and your poop bright green. And I mean BRIGHT green. Thanks for posting this info so I don't think I'm turning into a sheep or something.

    After reading this I feel so much better, just a few minutes ago I passed one of these "aliens." I was scared/worried, but after realizing it was the vast amounts of Kool-Aid (grape, cherry, orange, grape berry, etc. that I drank over the past few days I feel okay about it. I have been drinking more Kool Aid than eating actual food. Don't worry I have been eating but mostly soup. It's fast and I just do not have a lot of time. Todays my first day off and I'm writing about my poop, ... sad.

    Yeah, I hear you. I'm snowed in an the only thing I can do is look at stupid web sites. I've been to Poop Report three times already today. At least there's one bright spot in this endless tunnel of white poo. We're supposed to get three more inches tomorrow! AHHH!!!!!

    I found Jesus! He was behind the sofa the whole time!

    Just wanted to say, my brother and I too ate Boo Berry cereal religiously as children. We would then marvel at the flourescent green poop we produced there-after. Thanks for stirring up some fond memories!

    pooboytoy's picture

    i have had a relazation fter this article. the blueish greenish shite that i ahve had four four days is due o the fact that i have been eating too much frosting from a cookie cake. consumed i guess in its form you can achieve blue poo. that is my theory. unfortunatley i have no more cookie to test such a thought.

    pooboytoy's picture

    o btw its is black frosting that makes this color

    I live in Guam, I decided to eat half of a fresh coconut. I husked it myself. Result: emerald green poo! Thank goodness for your funny and informative site.... I haven't laughed this hard since we got stationed here on The Rock.

    Emerald green! Damn I wish I could experience that. But alas, I can't. I'm allergic to coconut! Fresh coconut result: anaphylactic shock.

    I was astonished to notice this morning i had the screaming green squits can someone help me get to the bottom of this i didn't eat n e thing green so im just speechless thx

    anonymous's picture

    I went out drinking last night, and this morning a dozen beer and a full box of Fruit Loops later I took a greenish blue poo, I was rather scared but at the same time astonished as I'd never seen anything like this before, I thought I had a vitamin deficiency or something, I was seriously thinking about consulting a physician, but I decided to scour the internet to see what I could find, luckily I stumbled upen your site, now I know there is nothing wrong with me, thank god for a world where within a few minuted and clicks of the mouse you can find about why your shit is blue and read up on people experiences from around the world, amazing isnt it?

    well I haven't done any empirical research on this phenomena lol, but I have noticed that when I drink large amounts or cherry koolaid, my shit is a nice deep red the next day

    Fiorela's picture

    Hi , I need help, I have been pooping little bits of green for the last 2 days. I do not think i have changed anythin in my diet. I drank tea yesterday and coffe this morning, but no kool aid.
    i have only eaten ham and chesses sandwiches and tuna, so what could be causing the color of my poo.

    Fiorela's picture

    oh damn , i figured it out, it must bee this gelatin like, purple sweet.

    Eating 3 bowls of Magic Stars (knock off Lucky Charms) (Dyes: Yellow 5 & 6, Red 40, Blue 1, Blue 2) and 3 bowls of Crunch Berries (Strawberry juice concentrate, Red 40, Yellow 5 and 6, Blue 1) for dinner will result in spinach colored poo the next day.

    Thank God for this site. I just spent an hour searching for 'green bowel movements' (good jumping off place if your 8 month old is filling his diapers with green gunk) and got nowhere fast. Got desperate and typed it 'green poop' and found this site. Nice to know I'm not dying or have been experimented on by aliens during the night, lol.

    Jesi's picture

    My poop's been green too. After reading this, I think it's all the Crunch Berrie's I've been eating!!

    Man is this shit crazy, after drinking 4 packs of p-sarus rex I grew a tail reminicent of the swamp thing. Now I can't get enough of it. Green poo for ever. Ya-hoooooooo.

    I had a week of heavy boosing in New orleans and was drinking copius amounts of blue gatorade for the hangovers. I started pooping green and almost had a panic attack because I thought I broke something! After about three days it went away and everything's ok...thanks dr. poo

    Mako's picture

    Wow, I'm glad I found this. I was freaked out, but I realized that yesterday I consumed a large amount of Blastin Berry Hawaiin Punch, which happens to be bright blue. Never knew that could happen!

    me's picture

    This is friggin hilarious!!! I looked online, because my poop has been green and getting greener until today, 3/14, when it looked as though someone had actually dumped bright green food coloring in the toilet. Then I read a few lines and noticed that I had eaten about a full giant box of crunchberries over the past 2 days. At first I thought that this was just my body preparing for St. Patty's day, but now I am edumacated!

    Minute Maid Grape Medley's picture

    You are really a genius. Thanks to you i'll be able to sleep peacefully tonight knowing that my colin does not have "gain green". I'd been drinking this delicious Minute Maid Grape Medley Fruit Soda. My poop was green and I was really starting to worry. I went on line thinking that I would learn that something really awful was wrong. I was getting sick just thinking about my obvious serious illness. Was I ever relieved to read your website. It did cross my mind that it could be the grape sode but I wasn't convinced until I read your website. Thanks for the very helpful information.

    Chad's picture

    After consuming roughly 500mL of Wild Watermelon Kiwi "Mad Scientwists" Kool-Aid, I had defecated a substantial amount of green poo... another test perhaps?

    chris in germany's picture

    i have been pooping , get this. AQUA green/blue poops. like lava lamp blue. and duh, it is the new fantastic FANTA berry blue soda, which i have been drinking like a crack addicts been smoking.

    thanks dr. poo from germany!

    Blueberries can also have the same wonderful, Kelly Green. It doesn't matter if the berries are fresh or frozen, the same results will happen, and it doesn't take very many of them to have the smallest effect.

    Grape Koolaid strikes again...making yet another hit for this site...glad I found it anyways, lots of interesting facts on here...hehe

    Krystle's picture

    WOW what a relief it is to have found this site! I am another one of the college kids who eats nothing good but crap snacks. To my surprise i went to "drop a spirit stick" as my roomate calls and saw bright green poop! The last thing i wanted to do was call my mother and say i needed to see my doctor because i have green poop! Thankfully i typed in green poop on google and found this site! I didn't realize that i had been eating alot of fruit gushers. So there's another one to add to the list of green poopoo! Thanks alot for saving me an embarrassing call home to mom!

    Sandi's picture

    Ya know, it is so funny, how this study of yours, which is really funny in reality, has actually helped many concerned moms. Moms get freaky at the site of a strange colored poop coming from their children. My 2 year old daughter had the brightest green poop I have ever seen. I was only mildly concerned since I have had this situation with my other daughters. But it seemed so bright I got on the net and sure enough found your site. What has my daughter been drinking this week you ask? Well sippy cup after sippy cup of purple kool-aid. LOL. Thanks so much for this interesting and yet strangley helpful study. :-)

    Grape Gatorade is yet another culprit for the bright green poop! Bottoms Up!

    Cody's picture

    I just had a nice green crap, and I told my friend about it... She thought I was a whack job. I always thought it was green when you are sick, but it might just be coincidencial that it's green usually when I'm sick... I told her about it, and I came on the interweb to get proof, and found this site... Awesome tests by the way.

    magiklogs's picture

    After eating some really cheap generic brand of froot loops, I noticed that if I had a big enough bowl of the stuff I shit purple-blue. The cereal had a lot of blue and purple rings which was the culprete of my ghastly almost black poo. Also some medecine capsules are made with a certain dye that turns poo green. Antibiotics (some not all) also make poo green. I hope all this info helps someone reading these messages. I know I was Pretty scared when I first started taking anti-depressants and I shit green, but I soon realized that it was the blue/red capsules that were doing it.

    Dumbass's picture

    Maybe this "concerned mother" should stop feeding her kids tripe like kool-aid. Ingesting all that food colouring is gonna give them cancer.

    Dear Poopreport,

    I love you. YAYEYAYE

    crank's picture

    ive had green poop for like 2 months straight, and it must be the fierce grape gatorade. i go through about 3 bottles a day!

    Snackycakes's picture

    I really enjoyed your sight, especially being a nurse and knowing how frightened we all get when something abnormal comes out of orafices. I for the first time drank alcohol in,well, a long time! I bought thed Fierce grape Gatorade and it led to some fiercer green diarrhea. On top of it I have to take laxatives due to IBS (irratable Bowel Syndrome) Makes for a nice trip to the ladies room. Anyway another thing that changes our poo green is licorice. Check it out next time you go to the movies, you will have a show of your own. LOL! Tata for now all!

    i had a large blue slurpee and the next day i enjoyed observing green feces in the crapper !

    My son who is special needs is tube fed....Last night and today the poo was quite green...After reading many posts I have now come to the conclusion its the purple pedialyte he is on...This has recently been added to his diet due to dehydration so I'm guessing this is the culprit!..Thanks!

    Relieved's picture

    Thank you so much! For a couple of days my poop has been green and I started to get worried. I recently went to the movies and I had a blue slushie and realized that the blue dye must have been turning my poop green.
    Thanks again!

    I've been eating a lot of strawberries and raisins in the last week. My poo has been pink! That's one to add to the list of colors and it's all natural, too! Organic pink poop.

    I just took a monster dump and peeked into the bowl ... omg I saw something round, tough and GREEN, it's the TEENAGE MUTANT NINJA TURDS!!!

    PoopGoesTheWeasel's picture

    I looked in the toilet and what did I see? A plump green doodie was a lookin' at me. I tried to flush it, it kept swirlin' around, this turd was too fat, there's no way it was going down. It said "Why do you drink Berry Blue Typhoon, and poop me out green like mold?" I said "I got the plunger, so do what you're told!"

    I went online for the same problem as most of you guys. The green stool has been driving me nuts! I now realize that eating a blueberry snowball from ice planet is the reason why its this way. GREAT site!!!!

    Wow that a load off my mind, I've been drinking blue shasta not even alot of it and my poop was green to. It must have alot of that dye in it.

    I just recently had the same problem of green poop and because of this site realize there is nothin wrong. Another product besides kool aid to use would be SPARKZ
    Vodka Blueberry. man did it ever go green.

    Oh ya you must be 18 to drink it

    i was making chocolate candy yesterday trying to get a dark blue color. i eventually was happy with it (after lots of food coloring) and tried some before i give them away as gifts. poo...after only 2 pieces of candy!! i think i might give my friends some sort of disclaimer when i give them the candy was blue Wilton candy colors(oil-based)

    This was definitely a helpful site, MY GREEN SHIZIT WAS DUE TO JUICE BOXES. It was a new kind, some "Berry Berry" shit. I thought I was dying , but no more.

    I am so relieved to find this website. I went to
    Disney's Animal Kingdom last Friday and tried to
    be a fun mom by getting a tube of the blue powdered sugar that is being sold in many candy shops. Lots of blue dye as my daughter and I can
    attest too as we laughed at each other's blue lips, tongue and teeth. It was no laughing mattter though when my feces began turning the most brilliant shade of green I've ever seen the next day and several days after. I thought I was
    dying of some horrible intestinal cancer. Thanks for all your hilarious stories of green poop!!!

    captain crunch crunch berries w/ rugrats movie shapes have lots of blue, purple and green dye. i ate several large bowls of cereal combined with several micro-beers that evening, and voila, eureka, i crapped green as springtime. i'm attemping a repeat as i write.
