Creatine Monohydrate

Evidence: ★★★★★ · Status: OTC Supplement

In plain English

Your muscles have a tiny rechargeable battery for explosive effort. Creatine makes that battery bigger, so you get 1–2 extra hard reps and recover faster between sets. It's the most proven, cheapest sports supplement that exists.

How it works

Creatine is taken into muscle by the SLC6A8 creatine transporter and phosphorylated to phosphocreatine by creatine kinase (CKM). Phosphocreatine donates a phosphate to ADP to regenerate ATP during efforts of 1–10 seconds — the phosphagen energy system. Supplementation raises intramuscular phosphocreatine ~20%, extending peak power before fatigue. In brain, it buffers ATP in high-demand neurons.

Bottom line

If you take one supplement, this is it.

The human evidence

Among the most-studied supplements in existence — hundreds of RCTs and multiple meta-analyses consistently show small but reliable gains in strength, power and lean mass alongside resistance training, plus emerging cognitive benefit under sleep deprivation. One of the very few supplements with strong, replicated human evidence.

Stacks with

Whey/protein and carbs post-workout (the insulin bump helps uptake).

Availability & where to buy

Available over the counter. Widely available OTC — e.g. iHerb (ships worldwide); in Singapore also Guardian, Watsons, GNC, Shopee / Lazada. Look for a third-party-tested / GMP mark and check the dose per serving. The cheapest effective supplement — ~S$20–40 for 3–6 months of monohydrate. Buy plain “creatine monohydrate” (Creapure is a quality mark); skip pricey “advanced” forms.
