The Claim
Creatine supplementation at 5g/day for six weeks is associated with a 4.25-fold increased risk of reporting side effects compared to placebo, with no serious adverse events, indicating a low but notable rate of minor, self-reported discomfort.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 5 grams of creatine daily for six weeks is linked to a 4.25 times higher rate of minor, self-reported side effects compared to taking a placebo, with no serious health events reported.

When creatine is taken daily, it draws water into the gut lining, causing the intestines to swell slightly. This swelling activates nerves in the gut wall, which send signals that make a person feel bloated, gassy, or nauseous.
What the research says
1 studyStudy: The effects of creatine supplementation on cognitive performance—a randomised controlled study
People who took creatine pills for six weeks were about four times more likely to feel mild side effects like stomach upset than those who took dummy pills, and no one got seriously sick — just like the claim says.
