Creatine dose, benefits & safety from Dr. Rhonda Patrick: - Standard muscle dose is 5 g/day of creatine monohydrate - the most well-researched form - but muscles are "very greedy" and consume most of it before it reaches the brain. - Getting creatine into the brain requires higher doses: one German study found that at 10 g/day, MRI scans showed creatine levels rising in key brain regions above what the brain produces on its own. - Creatine shines under brain stress - sleep deprivation, intense cognitive work, travel fatigue. One study gave sleep-deprived subjects 0.35 g per kg bodyweight (roughly 20-25 g) and they performed not just at baseline but above it. - The phosphocreatine system has a frontal bias - the brain areas most associated with strategic planning and working memory rely on it most heavily. "It's one of the most well-studied supplements out there. If it was unsafe, we really would know." @foundmyfitness on @hubermanlab
