Frequently Asked Questions  

What are EAAs?

Essential amino acids (EAAs) are amino acids that the 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 does “bioavailable” mean?

Bioavailability is the measure of the amount of a nutrient used by the body on a cellular level after ingestion.
