5-HTP is an endogenous, intermediate Amino Acid formed from Tryptophan. Exogenous 5-Hydroxytryptophan is manufactured as a supplement as a means of bypassing the first step in the production of endogenous Serotonin.
Acetyl-L-Carnitine is the O-acetyl derivative of Carnitine - ALC is also naturally present in the body (i.e. it is endogenous) and occurs naturally in small amounts in some foods. Approximately 7.5% - 10.2% of the body’s total Carnitine content is in the form of ALC.
Chondroitin Sulfate is an endogenous Glycosaminoglycan (GAG) - it is also consumed in diets containing Meats. It is composed of 52% Glucuronic Acid + 48% N-acetyl-D-galactosamine + Glucosamine Sulfate. Although Chondroitin Sulfate is often referred to as a singular (homogeneous) substance, it is actually, several compounds.
Setria® Glutathione Tri-peptide is a Sulfur-containing, water-soluble, Tripeptide composed of L-Cysteine, L-Glutamic Acid & Glycine. Often called the "master antioxidant," glutathione supports immune health and helps protect cells in the body from the damaging effects of oxidative stress and toxins.
Cysteine HCL is a Non-Essential, Glucogenic, Sulfur-Containing Amino Acid is synthesized in the Liver. Cysteine and Cystine readily convert to one another and have almost identical functions within the body (although Cystine is a less desirable form than "true" Cysteine). Cysteine HCL is Cysteine bound to 23% Hydrochloric Acid (HCl).
Cystine is a Non-Essential Disulfide Amino Acid formed within the body by linking two Cysteine molecules by their Sulfur atoms - i.e. Cystine is the oxidized form of Cysteine. Cysteine and Cystine readily convert to one another and have almost identical functions within the body.
