R-Lipoic Acid

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. It also has characteristics, including significant antioxidant effects, that contribute to liver, brain, nerve, and eye health. Studies indicate that supplements containing only R-lipoic acid appear to be better absorbed than supplements containing both R-lipoic acid and S-lipoic acid, with results showing twice as much ALA appearing in the bloodstream after an oral dose of R-Lipoic acid. Because R-Lipoic acid is the form best utilised by the body, Thorne provides R-lipoic acid bound to sodium, providing it in its most stable, absorbable form.

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 realised 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 oxidised 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. ALA also increases intracellular glutathione and CoQ10 levels. Its other mechanisms of action include promoting normal protein glycosylation and inhibiting the enzyme aldose reductase, which in turn inhibits conversion of glucose to sorbitol.
