Hi all, im asking this because yesterday i went to donate blood for the first time and they asked me stuff about my medical history to make sure im ok to donate.

They asked me if i’m taking or took in the past some supplements and i said yes cause i take creatine monohydrate and protein powder. When the doctor heard this said that i absolutely shouldn’t because it damages my kidneys.

I was a bit shocked because, being someone that just doesn’t trust the internet blindfolded (even when the absolute majoriy of reputable sources are kinda unanimous on saying that creatine is safe to take), before starting with creatine i went to my doctor and asked if i were ok taking it and he said yes just dont exceed the suggested dosage.

so im asking because im no one to dispute a doctor’s claim, but i got two very differente responses from two doctors so i’d like a clearer view on which advice to follow.

thank you :)
