Is Creatine monohydrate worth it?

One of the most-studied, best-value supplements there is. Plain monohydrate is the form that works — skip the HCl/buffered/micronized markups that cost 3–5× for no added effect.

The call

A large trial base supports strength, power, and lean-mass gains with training; monohydrate is the reference form and alternatives haven't beaten it. The cognitive signal is emerging, not established — preliminary and population-specific (sleep-deprived, older, vegetarian), not a daily focus pill for a rested young adult.

Safety

Caution with diagnosed kidney disease or nephrotoxic meds — talk to your provider. Pregnancy: insufficient data; skip unless advised. Common and non-dangerous: mild GI upset and water-weight gain. The "creatine harms healthy kidneys" claim isn't supported.

Dose that matters: 3–5 g/day · timing irrelevant · loading optional
