Creatine Monohydrate

5 g per serving · 1 rounded teaspoon (~5 g)

Creatine monohydrate is commonly used to support strength, power output, and repeated high-intensity performance when paired with resistance training. NSF Certified for Sport does not change the underlying mechanism but reduces contamination risk for tested athletes.

Benefit language is intentionally cautious. Supplements may support outcomes when paired with appropriate training, nutrition, and individual health context.
