Introduction

This video explains the benefits and safety of creatine supplementation for people over 50. Dr. Richard Kelley, an ER doctor and weight management physician, discusses creatine's history, its mechanism of action, its effects on muscle growth, brain function, and cardiac health, and provides guidance on its safe usage.

Key Takeaways

• Creatine's History and Popularity: Creatine, initially used by athletes in the early 1990s, gained mainstream popularity due to Bill Phillips' "Body for Life" program.
• Creatine's Mechanism: Creatine acts as a phosphate donor, helping recharge ATP (adenosine triphosphate), the energy source for cells. This is particularly beneficial as we age and naturally lose muscle mass (sarcopenia).
• Benefits for Older Adults: Studies show creatine, combined with resistance training, improves lean muscle mass, strength, and function in adults aged 50 and older. Potential cognitive benefits include improved memory and processing speed, especially in women and those with low baseline creatine levels (vegans/vegetarians). There's also promising research on creatine's potential positive impact on cardiac health and neurologic diseases.
• Safety and Considerations: Creatine is generally safe for healthy adults but can interfere with kidney function tests. Individuals with kidney disease, those taking multiple medications, or those experiencing illness should consult their doctor before using creatine. Common side effects are mild (stomach upset, water weight gain).
• Recommendation: Dr. Kelley recommends creatine for those over 50 who engage in weight training and wish to maintain strength and mobility, particularly vegans/vegetarians. Always consult a doctor before starting any supplement regimen.
