Ingredients

What we cover, the effective dose ranges from human studies, and how strong the evidence is.

3 ingredients found
Beta-Alanine

3.2–6.4 g effective dose

4/5
Beta-alanine is a non-essential amino acid that combines with histidine to form carnosine in muscle tissue. Carnosine buffers acidity during high-intensity work.
Caffeine

100–400 mg effective dose

5/5
Caffeine is a central nervous system stimulant and the most studied ergogenic aid in sport science. It blocks adenosine receptors, reducing perceived exertion and improving alertness.
L-Citrulline

6–8 g effective dose

3/5
An amino acid that the body converts to L-arginine, raising plasma arginine more reliably than supplemental arginine itself. This supports nitric oxide synthesis and vasodilation.
