@protocolmd: Everyone takes creatine for the gym. The research keeps pointing somewhere else: your brain. Your brain is one of the body's hungriest organs, but it makes less creatine than it uses, so it leans on what crosses in from your blood. That's why researchers have been looking at creatine and brain energy, from sleep-deprived focus to how the brain refills its energy system. A few things stand out in the research: your baseline stores may run lower if you're vegetarian or vegan, if you're a woman (especially after 40), or if you're chronically short on sleep. The baseline the research keeps coming back to is simple: creatine monohydrate, the most-studied form. Talk to your clinician before adding a supplement. — Educational only, not medical advice. #creatine #brainhealth #longevity #cognitivehealth #healthspan
