Glutamine has recently been the focus of much scientific interest. A growing body of evidence suggests that during certain stressful times, the body may require more glutamine than it can produce. Under these circumstances glutamine may be considered a “conditionally essential” amino acid. Glutamine is involved in maintaining a positive nitrogen balance (an anabolic state) and also aids rapidly growing cells (immune system lymphocytes and intestinal cell enterocytes). In addition, glutamine is a regulator of acid-base balance and a nitrogen transporter.*

Source Naturals GABA (Gamma-Aminobutyric acid) 750 mg 45 tablets

SN0237
GABA (gamma-aminobutyric acid) is an amino acid derivative and a key inhibitory neurotransmitter. Neurotransmitters are chemical messengers that carry information between nerve cells or from nerve cells to other target cells. GABA is synthesized directly from glutamic acid. It has an inhibitory effect on the firing of neurons and supports a calm mood.

Source Naturals L-Proline/L-Lysine 275 mg/275 mg 60 Tablets

SN0757
L-Lysine is one of the 9 essential amino acids that cannot be made in the body. It is the basic raw material for carnitine synthesis. L-Proline can be made in the body, but low protein/vegetarian diets may not always promote optimal L-proline production. L-Lysine and L-proline amino acids are the precursors of hydroxylysine (HL), and hydroxyproline (HP), two constituents of collagen. Collagen is an essential component of arterial linings. Vitamin C, a strong antioxidant, is also essential for the production of collagen. Hawthorn berry and grape seed extract are potent antioxidants due to their high levels of proanthocyanidin. These proanthocyanidin-esters are excellent free radical scavengers.

Solaray L-5 hydroxyTryptophan (L-5-HTP) 100 mg 60 Capsules

SR36668
This unique product is a combination of natural L-5-hydroxytryptophan (L-5-HTP), Vitamins B-6 and C, and bioflavonoids. Clinical studies indicate that administration of L-5-HTP enhances synthesis of serotonin in the brain. Vitamin B-6 is the cofactor for enzymes that convert L-tryptophan to serotonin, and Vitamin C catalyzes the hydroxylation of tryptophan to serotonin. In addition, this product is enterically coated to enable the capsules to bypass enzymes in the stomach which would convert L-5-HTP to serotonin prematurely (before reaching the central nervous system). The L-5-HTP in this product is a natural extract of the Griffonia bean, not produced synthetically or by a fermentation process.
