Thorne A-lipoic Acid - 60 Capsules | Thorne The most active form of alpha-lipoic acid to support healthy nerve and brain function.Alpha-lipoic acid occurs naturally as a 50/50 mixture of R-lipoic acid (R-ALA) and S-lipoic acid (S-ALA). R-lipoic acid by itself functions as an essential cofactor for many enzymes involved in energy production.Alpha-lipoic acid, also known as thioctic acid, was discovered in 1951 as a molecule that assists in acyl-group transfer and as a coenzyme in the Krebs Cycle. In the 1980s, the scientific community realized that alpha-lipoic acid is also a powerful antioxidant. What sets ALA apart from other fatty acids is that it's an antioxidant in both fat- and water-soluble environments, and it's also an antioxidant in both its oxidized and reduced forms. This is unlike vitamin C, for instance, which is a water-soluble antioxidant, as well as vitamin E, which is a fat-soluble antioxidant.More information about this productUnfortunately, due to legislation concerning supplements, we are not allowed to provide (complete) information about this product.
