Frequently Asked Questions

What are essential amino acids?

Essential amino acids (EAAs) are amino acids that your body can’t produce enough of on its own, including leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan. EAAs support muscle growth and recovery.

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.

Frequently Asked Questions

What is nitric oxide?

Nitric oxide is a vasodilator that promotes blood circulation.

What are nootropics? 

Nootropics are substances that bolster cognitive function by altering levels of certain neurotransmitters, enzymes, or hormones in the brain. 

What is citrulline malate?

Citrulline malate is a precursor to nitric oxide, which increases blood flow to working muscles and promotes greater muscle pumps and heightened energy levels.

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 and endurance.

Frequently Asked Questions

What is citrulline?

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

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.

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.
