Frequently Asked Questions

What is citrulline?

L-citrulline is an amino acid involved in nitric oxide production, which increases blood flow to working muscles.

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.

What is beta-alanine? 

Beta-alanine is the modified version of the amino acid alanine. The body converts beta-alanine into carnosine, which supports exercise performance and endurance. 

What is betaine? 

Betaine is a naturally occurring amino acid-like compound that supports exercise performance, endurance, and cellular hydration.

What is alpha GPC?

Alpha-glycerylphosphoryl choline (alpha GPC) is a naturally occurring compound found in the brain and is known to support cognitive health.
