The building blocks of the body. Besides building cells and repairing tissue, they form antibodies to combat invading bacteria and viruses; they are part of the enzyme and hormonal system; they build protein and carry oxygen throughout the body and participate in muscle activity.

5–Hydroxytryptophan (5–HTP) – A precursor to the neurotransmitter serotonin. Used as a sleep aid, antidepressant, and an appetite suppressant.

L–Arginine – Plays an important role in cell division, wound healing, and the release of hormones. Helps grow muscle mass and reduce body fat.

L–Carnitine – A compound synthesized from the amino acids lysine and methionine. Transports fatty acids to cells where they are used for energy by muscles.

L–Glutamine – Used to build muscle protein in the body. Used as a supplement for body building and endurance activities. Relieves muscle cramps.

L–Lysine – Necessary building block for muscles. Plays a major role in calcium absorption, injury recovery, and production of hormones and antibodies.
