Issue being that if you took everything that's "probably harmless" at once, cramming your body full of supplements, you might just end up harming yourself with substances that are toxic above certain amounts (acute iron toxicity etc.). Also the more random stuff you take, the more likely it is that something you took actually does turn out to have been harmful later.

So no, you should not take something merely because it's "probably harmless".

You and I should not. But I'm also not going to bother correcting someneone taking homeopathy for a cold. It doesn't do anything. But unless it contains heavy metals, it also isn't hurting.

You are strawmanning what he said. What he said is much better summarized as if a substance has other beneficial effects and there is one that is potentially just placebo, then it is ok. That is completely different than your paraphrase.

Is there a particular rare kidney disorder that creatine is contraindicated for? Because kidney disease is not rare, something like 14% of US adults have kidney disease.

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.

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!

and the thing people seem to not understand: how exactly do you _expect_ to be able to notice this change? Its something that happens after you take it for a prolonged period of time (>7days) and only has a minor/medium effect.

It doesn't make you a genius. I think a better view on it is that it may mitigate some of the adhs symptoms (at least for me).

I can keep on track for a significantly longer time since ive started supplementing with it at ~15g/day - and while i dont feel a difference, i can observe it when actually paying attention to what i do / how often i drift off etc.

There's no way you need 15g/day after doing that for more than 2 weeks.
