I guess you refer to ppl with already existing kidney problems.
But even then ...ist it really hard on the kidneys? I mean sure it will change creatinine levels when tested but if it's actually harmful in this scenario could somebody please elaborate on the details/why?
add-on:
afaik creatine supplementation gets even scientifically tested on ppl in dialysis.
Yes it builds up in the kidneys but do 3-5g / workout day increase creatinin levels?
You guys think that c. means that much of extra stress on the kidneys? I really wonder not bc c. is that important but in order to understand the scenario.
Anyone maybe? Thanks in advance!
