Creatine supplements:
what actually matters
Creatine is a naturally occurring compound stored mainly in muscle as phosphocreatine, where it supports rapid ATP regeneration during repeated high-intensity efforts. It is one of the most extensively studied supplements in sports nutrition, with consistent evidence for improved strength, power, and training performance when used appropriately.

Dose context
3-5 g/day maintenance; loading optional.
What to evaluate first
Form differences are usually small in practice; creatine monohydrate remains the reference standard for efficacy and cost.
Important note
Early weight gain is usually related to intracellular water retention rather than fat gain.
Not all creatine forms are equal
Instead of treating all creatine products as interchangeable, SuppScoreLab can compare how the market behaves by declared form. That is where the gap between better and weaker products becomes visible.
Creatine Monohydrate
Declared form resolved from normalized ingredient data.
The strongest immediate signal is transparency. Products with no declared creatine form score materially lower on average than the leading declared forms in this cluster. That does not automatically make every undeclared product poor, but it does make independent evaluation weaker and reduces confidence in formulation quality.
