How much creatine is safe for kidneys?

For most healthy individuals, creatine supplementation at recommended doses is generally considered safe for kidney health. The International Society of Sports Nutrition (ISSN) suggests a daily dose of 3-5 grams of creatine monohydrate for most individuals, which is widely regarded as safe for renal function. However, individuals with pre-existing kidney conditions or impaired kidney function should exercise caution and consult with a healthcare professional before starting creatine supplementation. Additionally, staying well-hydrated and avoiding excessive doses are important considerations for kidney health when using creatine supplements.
