Creatine Monohydrate
Also known as: creatine, CrM, Cr, micronized creatine, creatine phosphate precursor
Effective Dosage
3-5 g/day maintenance; 0.3 g/kg/day loading phase (typically 5-7 days)
What the Science Says
Creatine monohydrate is a naturally occurring compound found in muscle tissue that helps regenerate ATP — the fuel your muscles use during intense exercise. Supplementing with it increases the amount of stored creatine phosphate in your muscles, allowing you to push harder, recover faster, and build more strength over time. Studies in the provided data show benefits across strength performance, sprint capacity, recovery from soreness, cognitive-motor tasks in athletes, and early-stage evidence for improving symptoms of major depressive disorder when combined with standard treatments. A typical loading dose is 0.3 g/kg/day for 5-7 days, followed by a maintenance dose around 3-5 g/day.
What It Doesn't Do
Won't make you stronger without actually training. Not a substitute for antidepressants or therapy — mental health benefits are early-stage and only studied as an add-on treatment. Doesn't reliably improve sprint performance in vegans and vegetarians despite raising muscle creatine levels. Won't cause dehydration or muscle cramps — that claim is not supported by controlled studies. Not proven safe for people with pre-existing kidney disease or during pregnancy.
Evidence-Based Benefits
Creatine monohydrate increases muscle creatine and phosphocreatine availability, enhancing strength, repetition performance, and recovery in resistance-trained athletes even after just 3 days of loading (PMID: 41579075). It also shows promise for cognitive-motor performance, improving dribbling, passing, and shooting in adolescent basketball players under dual-task conditions (PMID: 40758095). Emerging evidence suggests it may augment antidepressant treatment in major depressive disorder and support lean mass preservation during weight loss interventions such as GLP-1 receptor agonist therapy (PMIDs: 41558805, 41368199).

Absorption & Bioavailability
Good — creatine monohydrate is well-absorbed orally. Micronized forms may show slightly improved pharmacokinetic profiles (higher peak concentration), but standard creatine monohydrate is highly bioavailable. Muscle uptake is enhanced when taken with carbohydrates or protein.
Red Flags to Watch For
- A rare case report links creatine use to thromboembolism risk — anyone with clotting disorders or vascular risk factors should consult a doctor before use
- People with pre-existing kidney conditions should avoid creatine or use only under medical supervision — safety data in this population is lacking
- Pregnant women should avoid creatine supplementation — no safety data exists for this population
- High doses can cause gastrointestinal distress (bloating, cramping) — dose-dependent and not universal, but worth noting
- Two out of 17 participants in a mental health trial experienced hypomania or mania — people with bipolar disorder should use with caution and medical oversight
- Weight gain from water retention is common during loading — this is not fat gain, but may be misleading on the scale
