Creatine is a naturally occurring compound made from three amino acids (arginine, glycine, methionine) that your body produces and stores in muscle and brain tissue. It serves as a rapid recycling system for ATP — the energy currency of every cell. With over 1,000 published clinical trials, creatine monohydrate is the single most-studied supplement in sports nutrition, and the evidence has now expanded well beyond athletics into cognition, mood, bone density, and sarcopenia prevention in older adults.

Population-specific evidence. The creatine evidence summarized here is strongest for healthy adults and sport settings. Adolescent-athlete guidance is narrow and assumes appropriate supervision; it is not a blanket protocol for all minors. Pregnancy-specific safety evidence is limited, so adult training protocols should not be carried over to pregnancy without obstetric guidance. Evidence for creatine alone also does not establish added benefit or safety for stacks with beta-alanine, whey protein, or other ingredients.
Studies in older adults often assess creatine alongside resistance exercise, so benefits from a combined program should not be attributed to creatine alone. Creatine is not established as a stand-alone osteoporosis treatment or a replacement for care based on fracture risk.
Creatine is present in animal foods, and some cognitive studies have focused on people with lower dietary intake or under conditions such as sleep deprivation. Findings are mixed and do not establish a general cognitive benefit or a treatment for fatigue, Parkinson's disease, multiple sclerosis, or fibromyalgia.
Creatine use can affect blood creatinine measurements, so tell clinicians about supplementation when discussing kidney tests. People with existing kidney disease, abnormal kidney results, or questions about interactions with their medicines should seek individual medical advice before use.
Clear ingredient labels and credible quality testing can help assess product identity and contaminants; they do not prove greater clinical benefit. Creatine monohydrate has the strongest research base, and evidence for it should not be assumed to establish superiority for Creapure branding, blends, or other creatine forms.
Do I need to load creatine?
No. Loading (20 g/day for 5–7 days) saturates muscle stores faster — about 1 week vs 3–4 weeks at the standard 3–5 g/day. End-state saturation and benefits are identical. Most people skip loading to avoid GI upset.
Is creatine monohydrate or HCl better?
Monohydrate. Every other form (HCl, ethyl ester, buffered, nitrate, magnesium chelate) makes marketing claims of better absorption that fail to translate into measurable performance differences in head-to-head trials. Monohydrate is also the cheapest and most-studied.
Does creatine cause hair loss?
The persistent rumor traces to a single 2009 rugby-player study showing increased DHT. No subsequent trial has replicated either the DHT change or actual hair loss. See the full evidence review.
Will creatine harm my kidneys?
In healthy adults, no — confirmed by long-term studies up to 5 years and an ISSN position stand. People with pre-existing kidney disease should consult their physician. Read creatine and kidneys: myth vs reality.
