Creatine, once primarily known for its role in muscle building, is now being explored for its broader health benefits. A registered dietitian nutritionist, Sam McKinney of Life Time Fitness, has highlighted that the supplement, available in powder or capsule form, has recently been linked to cognitive, cardiovascular, and even bone health benefits. This has led to its increased use not just among athletes but also by celebrities and health professionals.
Notable figures such as singer Ciara and actor Mark Wahlberg have adopted creatine for energy support and athletic performance. Stanford neuroscientist Andrew Huberman has also praised its neurological advantages, describing it as the ‘Michael Jordan’ of supplements. The supplement’s role in brain function, including its potential to improve memory and alleviate symptoms in certain neurological conditions, is attracting considerable scientific interest.
McKinney explains that creatine’s role in the body involves aiding the production of ATP, the primary energy source for high-intensity activities. While traditionally linked to muscle growth, recent studies suggest it may also support heart health, as the heart relies on ATP for function. Additionally, there is growing evidence that creatine could benefit those with cardiovascular issues, such as heart bypass surgery patients, and may contribute to improved longevity by helping maintain muscle mass as people age.
McKinney also notes that creatine has been studied in relation to cognitive health, with mixed but encouraging results. Some research suggests it may help with depression and traumatic brain injuries but may worsen symptoms in bipolar disorder. These findings highlight the supplement’s potential as a supportive tool for cognitive and physical health, especially in populations such as the elderly or those with dietary restrictions.
While the majority of studies support the safety of creatine and its use in healthy individuals, experts advise caution for those with preexisting kidney conditions. They recommend consulting healthcare professionals before starting supplementation to ensure it aligns with individual health needs and to choose reputable products with third-party testing for quality assurance.
