“I have used creatine over the past few years on and off, but mostly off. I have learned to cycle it on and off. Every time I use it, whether it be in the loading phase or the maintenance stage, I have a problem with diarrhea. It never fails. It is the most distressing thing. Unfortunately, I will have to stick to pure protein supplementation, as creatine has proven to be useless to me for this solo reason.
Otherwise, I have seen the increase in muscle mass, the energy increase creatine gives me, but I can’t handle diarrhea every day. It is disastrous.”
“It seems that when I take the creatine first thing in the morning on an empty stomach, it runs through my system in about 30 minutes, giving me the runs. I do take the powder and dissolve it into 16 ounces of water as directed on the package and I even drink a glass more of water afterwards but it still goes right through. I took it last night after my workout – about an hour after I ate dinner and it didn’t seem to have the same effect as when my stomach is empty.”
“I have taken creatine before as a supplement when I was training as an athlete. Just recently I have started to use it again, although it seems to cause me to have a tight stitch feeling around my left lower rib in particular. Is this normal? Its a bit like a lactic acid feeling.”
“I have stopped taking the creatine now and the soreness has gone, maybe its to do with water being taken from the muscle? I have been doing crunches as well which might have aggravated the abdominal area whilst on the creatine.”
“I have diarrhea about and hour or two after I take it (creatine).”
“I am a young weight lifter that started taking creatine monohydrate a couple of days ago. I have had diarrhea over the weekend and wondered if this had anything to do with the supplement.”
Diarrhea and Gas
“I started taking creatine after a mountain bike ride around 7:30 pm. It comes in foil packets and directions are to empty a packet into 16 ounces of water. After an hour of ingesting the solution, I experienced a lot of gas. I went to bed and according to directions I took it first thing (6:00 am). After about 30 minutes, it gave me the ‘runs’.”

“I recently started taking creatine and have been having problems with it in relation to my stomach. I take the advised amount (no loading) with apple/grape juice and it is still causing distress to my stomach.”
Diarrhea and Shakes
“When taking creatine, I often experience nausea and gastrointestinal problems like diarrhea. I read that could be because the creatine is not dissolved yet? Should I mix the powder in advance and let it dissolve in the water for a while? Because I just put it in a glass of water, stir it and drink it instantly.”
“Also, another troubling experience I get from creatine is that I sometimes get the shakes. It’s like there’s a constant tension in my muscles and it shows when I handle a pen or a keyboard. It goes away after an hour or so. Does creatine affect muscle nerves?”
“I can live with the side effects because the product is great. I’m just a bit worried.”
Gastrointestinal Distress and Mood Swings
“I’m in the loading phase of creatine intake – have been taking around 30 g (6 tea-spoons) daily for the last three days (my weight is 102 kg / 225 lbs). I don’t know if this should be attributed to creatine or to other factors (like the very hot weather) but I’m going through not-too-pleasurable experiences:”
“Nausea, sporadic loss of appetite and, what bothers me most, anxiety – my mood during the day stays in a kind of “altered” state – like the one we all experience on the eve of a difficult exam or two seconds before the race starts.”
“Maybe, I should’ve taken more liquids (I guess, I undershot the norm of an ounce per pound by a wide margin, and I feel thirsty most of the time).”
“On the positive side, though, I already experienced a boost of energy during my gym exercises.”
