Creatine for Aging: Strength, Mass, Function

Join Dr. Altamash Raja and Dr. Darsh Shah on Medicine Redefined as they introduce Dr. Darren Candow, a leading researcher on creatine supplementation. The episode dives into the benefits of creatine, not just for muscle performance, but also for brain health, bone density, and cardiovascular health. Addressing myths and misconceptions, the conversation highlights creatine's potential role in cognitive function, aging, cancer prevention, and post-concussion recovery.
