#Creatine
The most-studied sports supplement — creatine monohydrate doses, loading, who benefits, and long-term safety data.
Creatine is a nitrogenous organic acid stored in muscle as phosphocreatine, where it rapidly resynthesises ATP during short, high-intensity efforts. Roughly half of body stores come from diet (meat and fish); the other half from endogenous synthesis. Vegetarians have lower baseline stores and often respond best to supplementation.
Best form. Creatine monohydrate has by far the strongest evidence base for strength, muscle gain and recovery. More-expensive forms (HCl, ethyl ester, buffered "Kre-Alkalyn", magnesium chelate) have not been shown to outperform it in head-to-head trials.
Doses. Two equivalent protocols: (1) loading with 20 g/day split into 4 doses for 5-7 days, then 3-5 g/day maintenance; (2) slow load with 3-5 g/day continuously, reaching the same muscle saturation after 3-4 weeks. Loading reaches saturation faster but with no different end state.
Benefits beyond strength. Emerging evidence in cognition (especially during sleep deprivation), bone health in postmenopausal women, and recovery from concussion. Effects are modest but consistent across recent meta-analyses.
Safety. Creatine monohydrate has one of the largest safety records of any supplement — decades of trials in healthy adults at standard doses show no clinically meaningful renal, hepatic or cardiovascular harm. People with pre-existing kidney conditions should consult a clinician.
On HealthyHerbology we cover creatine across men's muscle-gain and endurance contexts, women's lean-toning and bone-density angles, and sports-recovery supplementation.

Read entry ↗Frequently asked about Creatine
- Is creatine monohydrate the best form?
- Yes — creatine monohydrate has by far the strongest evidence base for muscle gain, strength and recovery. More-expensive forms (HCl, ethyl ester, buffered) have not been shown to outperform it.
- Do I need to do a loading phase?
- No, loading is optional. 3-5 g/day for 3-4 weeks reaches the same muscle saturation as a 5-day, 20 g/day loading protocol. Loading reaches saturation faster but with no different end-state.
- Is creatine safe long-term?
- Creatine monohydrate has one of the largest safety records of any supplement, with decades of trials in healthy adults. People with pre-existing kidney conditions should consult a clinician before starting.
