Creatine

Creatine replenishes phosphocreatine stores and helps regenerate ATP during high-demand effort. It is one of the most studied sports nutrition compounds and also has growing interest in cognition and recovery contexts.

Track it lightly

If you run a creatine experiment, track body weight and training markers alongside the supplement so the early water-weight change does not muddy the result.

Evidence snapshot

Creatine monohydrate has the deepest evidence base for improving high-intensity performance and lean-mass gains when paired with training.

Many alternative forms are marketed as better absorbed, but monohydrate remains the reference standard for both efficacy and cost-effectiveness.

Water retention and body-mass increases are expected effects for many users and should not be confused with poor tolerance.

Compound variations

Creatine monohydrate

Creatine

The default form for most users because evidence, price, and practicality are strongest here.

Common use case

Most performance and recovery experiments.

Dosage note

A steady daily approach is typically sufficient.

Creatine HCL

Creatine

Often marketed as more soluble or easier on the stomach, with a thinner evidence base than monohydrate.

Common use case

Users who have repeatedly struggled with monohydrate tolerance.

Dosage note

Evaluate claims carefully because marketing often outruns data.

Dosage and best practices

Dosage principles

  • Daily consistency matters more than exact timing.
  • Loading can speed saturation, but it is optional.
  • Use enough fluid and track body mass so the expected early weight shift is interpretable.

Best practices

  • Do not judge creatine after two or three inconsistent doses.
  • Pair it with a clear training block or cognitive experiment so outcome signals are not random.
  • Log dose, GI tolerance, body weight, and training output in the same place.
