Protein shakes and creatine supplements have become staples in fitness regimes for many, from newcomers to seasoned athletes, aimed at enhancing strength and muscle growth. However, warnings about possible kidney damage circulate widely on social media, leaving many concerned about their health with regular use of these products.

Dr. Karan Rajan, a surgeon affiliated with the UK’s National Health Service (NHS), recently delved into the effects of protein and creatine on kidney function in a video released on November 18. He emphasized that the risk largely hinges on whether individuals have healthy kidneys or pre-existing conditions.

According to Dr. Rajan, individuals with normal kidney function need not fear protein shakes. He cites scientific research indicating that even high protein quantities—up to three grams per kilogram of body weight—are not detrimental to healthy kidneys. Our bodies are adept at filtering the byproducts from protein metabolism, making protein shakes generally safe for those who follow balanced diet guidelines.

On the flip side, Dr. Rajan warns that for those with chronic kidney issues, increased protein intake could exacerbate their condition over time, placing additional stress on the kidneys. He recommends that such individuals limit their protein consumption to slow the progression of kidney damage and minimize the risk of future dialysis needs.

Turning to creatine, a supplement favored for its energy-boosting properties, Dr. Rajan asserts that it is also safe for healthy kidneys, with no substantial evidence linking it to kidney toxicity in individuals without health problems. However, similar to protein, those struggling with kidney disease should steer clear of creatine due to the lack of comprehensive research regarding its long-term effects in such cases.

Moreover, Dr. Rajan points out that creatine can complicate blood tests that assess kidney function. When taking creatine, serum creatinine levels may rise, potentially misleading healthcare providers into thinking there’s a kidney issue. He suggests utilizing cystatin C as a more reliable marker for evaluating kidney health among supplement users.

His advice is straightforward: while supplements themselves are not inherently risky, responsible usage is essential. Healthy individuals can safely use protein and creatine, but those with pre-existing conditions should exercise caution.

With the rising popularity of fitness supplements—especially among younger demographics—it's vital to remember that no supplement can replace a nutritious diet, proper hydration, and regular medical evaluations. Even in healthy individuals, excessive supplementation does not always yield superior results and may lead to digestive issues or unnecessary strain.

Dr. Rajan encourages individuals to gain a better understanding of their health before adopting trends prevalent in gyms or social media. His message is clear: while supplements may be safe for many, anyone with medical concerns should seek professional guidance first. True health stems from informed decisions above all else.
