Creatine: Strength, Muscle, and Brain Power — Why It’s in My Stack at 66

At 66, I found creatine to really boost my strength in the gym. It helped me add muscle, recover faster, and push through plateaus I thought were age-related. But what surprised me most wasn’t just the physical gains—it was the mental clarity, the focus, and the energy I felt outside the gym. That’s when I started digging deeper.

Creatine is a compound your body naturally produces in the liver, kidneys, and pancreas. It helps recycle ATP—your cells’ primary energy currency. Most people know it for muscle performance, but creatine also fuels the brain. Your neurons burn through ATP to send signals, reset after data transfer, and package neurotransmitters. Without enough creatine, your brain may struggle to keep up.

Recent studies show creatine may support:
– Cognitive performance — A 2023 randomized controlled trial found improvements in memory and reasoning tasks
– Neuroprotection — Creatine may buffer against age-related cognitive decline by supporting mitochondrial health
– Mental clarity and resilience — New neuroscience links creatine to reduced brain inflammation and enhanced neuroplasticity

Longevity scientists are now exploring creatine not just for muscle, but for brain aging, energy metabolism, and immune support. It’s affordable, safe, and well-tolerated—even in older adults.

Creatine isn’t just for bodybuilders. It’s for builders—of strength, clarity, and resilience. If you’re optimizing for aging well, staying sharp, and pushing physical limits, creatine deserves a spot in your stack.

I’m 66, not done. I’m building. And creatine helps me build—inside and out.
