NAC (N-acetyl-L-cysteine) is an antioxidant that helps increase glutathione synthesis, and potentially has benefit during oxidative stress.* NAC is the acetyl derivative of L-cysteine. While L-cysteine plays important metabolic roles as a key antioxidant, a glutathione precursor, and a natural source of sulfur for metabolism, it is unstable and can become degraded during absorption. NAC on the other hand, is more stable than L-cysteine. Taken orally, NAC converts into L-cysteine after being absorbed, and raises blood and tissue cysteine levels. As a dietary supplement, NAC is a highly attractive alternative to L-cysteine. NAC can also be used instead of L-cysteine as an adjunct to Item #70130 Original AntiOx. Free form amino acid, high purity, well tolerated, and in tablet form to insure potency.

Taurine is a semi-essential amino acid that plays a specialized role as an ion and pH buffer in the heart, skeletal muscles and central nervous system.* Taurine is also a potent antioxidant and antitoxin, and is particularly important to the liver and immune system.* Free form amino acid, high purity, well tolerated.

L-Tryptophan is an essential amino acid that is converted into L-5-Hydroxytryptophan (5-HTP) in the body. 5-HTP is then converted into serotonin and melatonin. Normal serotonin levels have been associated with normal moods, appropriate appetite and weight maintenance, and proper sleep.* Our 5-HTP is derived from a plant source, and is carefully tested to ensure its purity and to guarantee the absence of contaminants.

A formulation of 17 naturally occurring amino acids in their free forms, including 9 essential amino acids, as well as 5-L-Hydroxytryptophan (5-HTP). Contains no L-tryptophan. 5-HTP is in the same metabolic pathway as L-tryptophan, and is the immediate precursor to serotonin and melatonin. This formulation is appropriate for food-sensitive individuals.
