Muscle Power in Aging: Why Force Speed Matters More Than Strength Alone
Muscle power — the ability to generate force quickly — declines faster than strength with aging and is a stronger predictor of functional independence and fall risk. This article covers the evidence for power-oriented training and nutritional support.

Sedentary Behavior and Step Count in Aging: What the Evidence Says About Movement Thresholds
Low daily step count and prolonged sitting independently predict cardiovascular disease, metabolic dysfunction, and premature mortality. This article reviews the evidence thresholds and practical movement strategies for aging adults.

Low Cardiorespiratory Fitness: Evidence on Nitrate, Citrulline, and Beta-Alanine Support
For low cardiorespiratory fitness, training remains primary. Beetroot nitrate, citrulline, and beta-alanine may provide modest additive support in selected protocols.

CoQ10 and Mitochondrial Function: Age-Related Decline and Clinical Evidence
CoQ10 declines with age and statin exposure. Human evidence is strongest in heart failure and statin-associated muscle symptoms, while prevention use in healthy adults remains less certain.

NAD+ Precursor Supplementation and Cognitive Fatigue: Mechanism and Human Evidence
NAD+ precursors reliably elevate blood NAD+ in humans and activate mitochondrial energy pathways. Whether this translates to clinically meaningful reductions in cognitive fatigue requires larger, longer trials.
