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 :)

    I might be confused, but I thought creatine gives your muscles a minor"second wind" kinda thing so you can push yourself to do some extra reps? It’s not like a steroid kinda thing, I was told.

      Kinda, but the effect is almost imperceptible. It’ll help you get like one more rep on your last set, or maybe one more sprint, at sufficient intensity, which is a little bit of extra volume that does add up over time with proper consistency. So, not just “looking stronger.”

      The brain health effects that the influencers are talking about now are just hype, though.

      I’m only basing this on.anecdote, in school we had body kinetics and a group of us skinny guys the same weight were lifting and half took creatine and put on a lot of muscle real quick but were not any stronger than those of us that did not evenn after putting on 15 lbs more muscle or whatever.
