Alpha-Lipoic Acid
Price: $69.99 (USA Only)
The Universal Antioxidant with Metabolic Functions

DESCRIPTION
Alpha-Lipoic Acid tablets, contain 250 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.
FUNCTIONS
Alpha-lipoic acid is a nutritional coenzyme that is involved in
energy metabolism of proteins, carbohydrates and fats, has physiological
functions in blood glucose disposal, and is able to scavenge a
number of free radicals. Alpha-lipoic acid is a fat- and water-soluble,
sulfurcontaining coenzyme. It functions in the body much like
a B-vitamin, since it is involved in energy production. As part
of several multi-enzyme complexes located in the mitochondria,
alpha-lipoic acid is essential for metabolizing carbohydrates,
proteins, and fats, and for the conversion of their energy into
ATP. Two of these enzyme complexes, PDH (pyruvate dehydrogenase)
and alpha-KGDH (alphaketoglutarate dehydrogenase) 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, BCKADH (branched-chain keto-acid dehydrogenase),
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 activity and cell structure. When this
occurs, additional free radicals are produced which, in turn,
can result in more extensive damage to cells and tissues. The
uncontrolled production of free radicals is thought to be a major
contributing factor to many degenerative diseases. 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 sulfurcontaining 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.
INDICATIONS
Alpha-lipoic acid may be a beneficial dietary supplement for those
concerned about a more complete antioxidant defense system and
maintaining proper glucose metabolism. Dietary and supplementary
alpha-lipoic acid is efficiently absorbed, transported to the
tissues, and readily taken up by the cells.
