The community maintains that creatine and whey are not inherently harmful to organs, and that physicians often misinterpret elevated blood creatinine as a sign of kidney failure rather than as a benign metabolic effect of supplementation.

The community consensus is very strong, rejecting the idea that these supplements cause organ damage in healthy individuals. Research confirms that creatine monohydrate can indeed increase serum creatinine levels without reflecting actual renal dysfunction (observational studies and reviews, Journal of the International Society of Sports Nutrition). The use of cystatin C is scientifically recognized as a more accurate marker of renal function in this context (meta-analysis, Clinical Journal of the American Society of Nephrology). Regarding whey, there is no solid evidence linking moderate consumption in healthy individuals to hepatic or renal damage, classifying it as a standard dietary protein. The exaggeration lies in the generalized distrust of the medical profession, although the community is correct to point out a frequent gap in practitioners' training on sports nutrition. It is nonetheless wise to note that product quality (purity) remains a critical variable, as suggested in the discussions.
