Creatine for Longevity: Age-Proof Your Body

Creatine as an Anti-Aging Supplement

Aging brings a predictable decline in muscle mass, bone density, mitochondrial function, and cognitive sharpness. Sarcopenia — the progressive loss of skeletal muscle — begins as early as age 30 and accelerates after 50, increasing the risk of falls, fractures, and loss of independence. Creatine supplementation directly addresses several of these age-related challenges. By maintaining phosphocreatine stores in aging muscles, creatine helps preserve strength and functional capacity. Research shows that older adults who combine creatine with resistance training gain significantly more lean mass and strength than those who train without it.

Beyond muscle, creatine supports mitochondrial health by buffering cellular energy demands and reducing oxidative stress. Emerging evidence suggests it may also protect against age-related neurodegeneration, making it one of the few supplements with credible benefits across multiple systems that decline with aging.

Protocols for Healthy Aging After 40

In this section, you'll find targeted guides for using creatine as part of a healthy aging strategy. We cover creatine's role in combating sarcopenia, supporting bone mineral density, and maintaining cognitive function in later life. You'll also find practical dosing protocols specifically designed for adults over 40, 50, and 60 — because the optimal approach changes with age and activity level.

Our articles draw from clinical trials involving older populations and translate the findings into actionable recommendations. If you're new to creatine and want to understand the basics first, start with our creatine science guides before diving into longevity-specific protocols.
