Creatine for Muscle Strength And Growth

Research suggests that creatine supplementation may support muscle strength and growth, particularly when combined with resistance training, with one randomized controlled trial finding that creatine enhanced the muscle-building response to exercise in young men partly by reducing myostatin, a protein that limits muscle growth, beyond what training alone achieved. A 2020 review also identified creatine as a promising strategy for counteracting age-related muscle loss in older adults, though the authors noted that more research is needed to determine optimal approaches for this population. The available evidence is limited in scope — the directly relevant studies are few, and much of the surrounding literature addresses muscle physiology in clinical or disease contexts rather than healthy populations seeking performance gains — so broad conclusions should be drawn cautiously. Studies indicate that resistance training itself remains the primary driver of strength and hypertrophy outcomes, with creatine appearing to offer a supporting role rather than an independent effect.
