Leading Cardiologist Debunks Common Misconceptions Surrounding Creatine use
New York, NY - November 20, 2025, 09:04:39 EST – A widely-used fitness supplement, creatine, has long been shrouded in myths regarding its impact on kidney health and overall cardiovascular function. Now, Dr. Andrew Sauer, a prominent cardiologist at Mount Sinai Hospital, is challenging these long-held beliefs, presenting a thorough review of scientific evidence that demonstrates creatine’s safety and potential benefits for a broad range of individuals.
For years, concerns have circulated about creatine causing kidney damage and heart problems, deterring many from incorporating it into their fitness routines. However, Dr. Sauer’s analysis, published this week in the Journal of the American College of Cardiology, reveals that these fears are largely unfounded in healthy individuals. The increasing popularity of fitness and supplementation necessitates a clear understanding of creatine’s effects, particularly as the global sports nutrition market is projected to reach $79.3 billion by 2027, according to a recent report by Grand View Research. This clarification is crucial for athletes, fitness enthusiasts, and healthcare professionals alike, enabling informed decisions about supplementation and potentially unlocking performance enhancements without undue risk.
Creatine, a naturally occurring compound found in muscle cells, plays a vital role in energy production during high-intensity exercise.Supplementing with creatine increases the body’s stores of phosphocreatine, allowing for more rapid ATP regeneration – the primary energy source for muscle contractions. Dr. Sauer’s research indicates that, when used responsibly and within recommended dosages (typically 3-5 grams per day), creatine does not pose a notable threat to kidney function in individuals with pre-existing healthy kidneys.
“The narrative around creatine has been dominated by misinformation,” explains Dr. Sauer. “numerous studies have consistently shown that creatine supplementation does not lead to kidney damage in healthy individuals. While those with pre-existing kidney conditions should exercise caution and consult with their physician, the vast majority of the population can safely benefit from its performance-enhancing effects.”
The cardiologist also addressed concerns about creatine causing heart problems. He clarified that while some individuals may experience temporary water retention, leading to a slight increase in body weight, there is no evidence to suggest that creatine directly contributes to cardiovascular disease. In fact, some research suggests creatine may even offer protective benefits against certain heart conditions, though further investigation is needed.
Dr. Sauer emphasizes the importance of sourcing creatine from reputable brands to ensure product purity and quality. He also advises individuals to stay adequately hydrated while supplementing with creatine, as it draws water into muscle cells. He concludes that, based on current scientific understanding, creatine is a safe and effective supplement for enhancing athletic performance and supporting muscle growth when used responsibly.
