Amino Acid - L-Glutamine


L-Glutamine

L-Glutamine is the body's most abundant non-essential amino acid. It becomes conditionally essential (requiring intake from food or supplements) in states of illness or injury. Therefore, it's not uncommon for those regularly exercising (hopefully, you!) to supplement L-Glutamine (or for sport supplement manufacturers to add additional L-Glutamine to protein supplements), as the physical stress of exercise will decrease L-Glutamine concentrations.

Typically, I (GP) have known bodybuilders supplement L-Glutamine during pre-competition diet. The reason, not only to reduce fatigue, but, to help suppress carbohydrate craving.
