What are micronized free-form amino acids?

Micronized free-form amino acids are single amino acids that are already in a pre-digested form for faster absorption by the body.

Why is nitric oxide important?

Nitric oxide plays a key role in exercise endurance because it’s a vasodilator. A vasodilator is a substance that supports the dilation of blood vessels for increased blood flow.
