Universal Antioxidant Alpha Lipoic Acid – 60 caps


Alpha-Lipoic Acid capsules, provided by Douglas Laboratories, contain 100 mg of pure alpha-lipoic acid.
Alpha-lipoic acid is a non-vitamin coenzyme that carries out important metabolic and antioxidant functions in
the body.
Alpha-lipoic acid is a nutritional coenzyme that participates in the energy metabolism of proteins,
carbohydrates and fats, with a particular role in blood glucose disposal. It is also able to scavenge a number of
free radicals. As both a fat and water-soluble, sulfur-containing coenzyme, alpha-lipoic acid functions in the
body as part of several multi-enzyme complexes located in the mitochondria. Alpha-lipoic acid is essential for
metabolizing carbohydrates, proteins, and fats, for the conversion of their energy into ATP. Two of these
enzyme complexes, pyruvate dehydrogenase (PDH) and alpha-ketoglutarate dehydrogenase (KGDH) are part
of the citric acid cycle (Krebs cycle), and as such assume a central role for general energy production.
Another lipoic acid containing enzyme complex, branched-chain keto-acid dehydrogenase (BCKADH), is
involved in deriving energy from the branched chain amino acids, leucine, isoleucine, and valine. A related
metabolic function of alpha-lipoic acid is its role in blood glucose disposal. This important coenzyme appears
to be necessary for the normal transport of blood glucose into the cell. This may be explained by its functions
in the glucose-metabolizing enzymes, PDH and alpha-KGDH, but some researchers suspect a more direct role
in cellular glucose uptake at the cell membrane. As early as 1959, alpha-lipoic acid was suggested to be an
antioxidant, since it could extend the actions of vitamin C in guinea pigs, and those of vitamin E in rats. It is
only recently, however, that the specific actions of alpha-lipoic acid in free radical quenching, metal chelation,
and antioxidant regeneration have been investigated. Body cells and tissues are threatened continuously by
damage caused by toxic free radicals and reactive oxygen species (e.g., peroxides) which are produced during
normal oxygen metabolism, and by toxic agents in the environment. Free radicals, once formed, are capable
of disrupting metabolic function and cell structure. When this occurs, additional free radicals are produced
which, in turn, can result in more extensive damage to cellular structure and function. Alpha-lipoic acid is
unique among biological antioxidants, because it is soluble in both water and lipids. This allows it to neutralize
free radicals just about everywhere in the body, inside and outside the cells. Due to its unique sulfur containing
structure, alpha-lipoic acid can scavenge several types of free radicals, such as the highly reactive
hydroxyl, and singlet oxygen free radicals. It is also capable of suppressing the generation of free radicals in
the first place, since alpha-lipoic acid chelates transition metals, such as iron and copper. Because alpha lipoic
acid is involved in so many different antioxidant functions in virtually all body tissues, it has been called
the universal antioxidant. Besides being a universal free radical scavenger, alpha-lipoic acid can also recharge
other antioxidant systems throughout the body. As mentioned earlier, it can extend the activity of vitamins C
and E. In addition, alpha-lipoic acid can also regenerate glutathione.
Alpha-lipoic acid may be a beneficial dietary supplement for individuals who wish to
supplement with lipoic acid.
