It’s not completely harmless, for me it causes heart palpitations that are so bad my watch tells me I’m in atrial fibrillation. Yes I know this sounds crazy. I’ve ruled everything else out. No, it is not creatine mixed with caffeine or whatever. Just pure creatine. No, I don’t have any other heart issues. I can give myself an irregular heartbeat just by having some creatine. It doesn’t happen otherwise. I have seen a cardiologist, he said it’s rare but it is theoretically possible.

Have you ruled out your supply is contaminated with something that causes your side effects?

That might be relatively likely.

Scientifically interesting, but it's kind of the same problem whether supplements are dangerous on their own or from contamination. Given how little value an unnecessary medication is it makes no sense to test it to eliminate a risk that is also eliminated by not taking it.

No, I haven’t, I could theoretically try a new brand and see what happens

Given creatine is present in several foods, do you have an intolerance to those as well as creatine in supplement form? Curious if it's a simple allergy or the dosage.

Creatine breaks when cooked, so for the most part he's not gonna get too much from eating a steak or whatever. Taking 5g/day of pure creatine to satiate your stores might be too much for this particular individual. Anyway, the parent produces its own creatine as well!

Smaller pieces, probably
