Creatine Monohydrate
Creatine · Creatine Mono
Creatine monohydrate is one of the most extensively researched and well-supported supplements in all of sports science and nutrition. It is a naturally occurring compound synthesized from amino acids (arginine, glycine, methionine) in the liver, kidneys, and pancreas, and is also obtained from dietary sources (meat and fish). Approximately 95% of the body's creatine is stored in skeletal muscle as phosphocreatine, serving as a rapid energy buffer for ATP regeneration during high-intensity activity.,Beyond its well-established role in exercise performance, creatine has emerged as a promising compound for brain health, cognitive enhancement, and longevity. The brain is highly metabolically active, consuming ~20% of total body energy, and relies on phosphocreatine for rapid ATP buffering. Creatine supplementation has shown cognitive benefits in sleep-deprived individuals, vegetarians (who have lower baseline creatine), and older adults. Emerging research connects creatine to neuroprotection, depression treatment, and even longevity via cellular energy optimization.,Creatine monohydrate is the gold standard form - no other form (HCl, ethyl ester, buffered) has shown superiority despite marketing claims. It is one of the few supplements with a truly robust evidence base, supported by over 500 peer-reviewed studies and endorsed by the International Society of Sports Nutrition (ISSN) as safe and effective.
Take daily with any meal. Mix with water or any beverage. No loading phase necessary (3-5g/day reaches saturation in 3-4 weeks). Take consistently - timing within the day does not matter significantly.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
How it works
Creatine is transported into cells via the creatine transporter (SLC6A8) where it is phosphorylated by creatine kinase to form phosphocreatine. Phosphocreatine serves as a rapid-access energy reserve, donating its phosphate group to ADP to regenerate ATP within seconds - faster than any other metabolic pathway (glycolysis, oxidative phosphorylation). This phosphocreatine shuttle is critical in tissues with high and fluctuating energy demands: skeletal muscle, cardiac muscle, and brain.,In muscle, increased phosphocreatine stores enable greater power output, more training volume, and improved recovery between sets. Over time, this increased training capacity drives greater muscle hypertrophy and strength gains. Creatine also increases intracellular water retention (cell volumization), which activates mTOR and other anabolic signaling pathways.,In the brain, the phosphocreatine energy buffer supports cognitive function under metabolic stress (sleep deprivation, hypoxia, complex cognitive tasks). Neuroprotective effects include maintenance of mitochondrial membrane potential, reduction of oxidative stress, and anti-apoptotic signaling. Creatine also modulates neurotransmitter synthesis and may enhance dopaminergic function.

Pharmacokinetics
Storage. Store at room temperature in a cool, dry place. Creatine monohydrate powder is extremely stable - shelf life of 3+ years when kept dry. Does not require refrigeration. Degrade only in solution over extended periods (mix fresh daily).
Regulatory status
Classified as a dietary supplement in the US (not FDA-approved for any medical condition). Not banned by any major sports organization (WADA, NCAA, IOC, NFL). Widely available over the counter. Creapure (German-manufactured monohydrate) is considered the gold standard for purity.
