The antioxidant alpha-lipoic acid is only produced by the body in minute quantities. We receive most of the alpha-lipoic acid we need through the food we eat: red meats, such as beef, and also organic meats are among the most important sources.
Alpha-lipoic acid is an antioxidant and helps the body to reduce oxidative stress. Alpha-lipoic acid counteracts free radicals and can support the formation of intracellular antioxidants (e.g. glutathione). Alpha-lipoic acid contributes to the metabolism of carbohydrates by improving blood glucose levels.
The better form R-alpha-lipoic acid NaRLA
The commercially available dietary supplements containing alpha lipoic acid with 50% of R-alpha-lipoic acid and 50% of S-alpha-lipoic acid. Naturally produced by the human body is the "R" form of lipoic acid. The "R" form is therefore the biologically active form, it is the body's own and does not need to be converted first. The "S" form (the synthetic optical isomer) is therefore not equivalent biologically active. Unlike other forms of lipoic acid, R-lipoic acid is more stable in the body. The increased stability is the reason for the increased absorption and bioavailability compared to R-lipoic acid.
The use of lipoic acid as an effective antioxidant has increased
The main reason for this is the fact that the body routinely converts lipoic acid into dihydrolipoic acid, an even more effective anti-oxidant, which is able to counteract the harmful effects peroxynitrite radicals.
In addition, lipoic-acid, in the form of dihydrolipoic acid, is able to restore vitamin C, which in turn can form new vitamin E. Lipoic acid's multi-talented properties may contribute to its popularity among consumers – especially among athletes who want to optimize their energy metabolism.
A less well-known reason also supports the use of lipoic acid as a dietary supplement: it compensates for a lack of red meat and animal fat, which athletes today often avoid. Red meat and animal fat are a rich source of lipoic acid. That is why lipoic acid is a very popular nutritional supplement among vegetarians and vegans. Lipoic acid is also noted for its supportive effect against the formation of cataracts. The water-soluble and anti-oxidative properties of lipoic acid lead to oxidative relief in the aqueous milieu of the eyes.
R-lipoic acid has a high redox potential, which is why it plays a key role in the body's anti-oxidative network. Alpha-lipoic acid is an effective sulphur-containing anti-oxidant. It helps to balance stress hormone levels, and supports the metabolic functions of the liver.
Recent findings have shown that R-lipoic acid helps to retain a high basal metabolic rate (thermogenesis) and is thus important for the self-regulation of body weight. R-lipoic acid works best in combination with other antioxidants.
