Alpha-lipoic
acid: also known as thioctic acid, is
a disulfide compound that is a cofactor in vital
energy-producing reactions in the body. Alpha
lipoic appears to function in two ways in the
body. One is metabolic function, the other is
antioxidant function.
Metabolic function: Alpha lipoic
serves as a co-factor for a number vital enzymes
responsible for the conversion of glucose, fatty
acids and other energy sources into chemical energy
(ATP). On glucose metabolism, alpha lipoic enhancing
glucose uptake in muscle cells and preventing
glucose-induced protein modification. Some studies
have revealed favorable effect including increase
glucose uptake, promotion of neurite growth and
chelation of transition metals thought to play
a role in diabetic neuropathy.
Antioxidant function: It is
also a potent antioxidant in the body. It soluble
in both water and fat. Thus alpha lipoic acid
works both inside the cell and at the membrane
level. Numerous studies have produced promising
results with lipoic acid in neuropathy. Lipoic
acid has demonstrated antioxidant properties that
help reduce or eliminate a sequence of events
that include reduced endoneural blood flow and
oxygen tension, which are pre-requisites of neuropathy.
Alpha lipoic acid is readily reduced in cells
and tissues. Once inside the cells, alpha-lipoic
acid is broken down to dihydrolipoic acid (DHLA).
Most importantly, both lipoic acid and its metabolite
are potential in performing antioxidant functions,
which can destroy almost all of free radicals
such as superoxide radicals, hydroperoxy radicals,
and hydroxyl radicals.
Alpha-lipoic acid helps other antioxidants like
vitamin C, vitamin E and glutahione in two significant
ways. First, through the enhancement of the antioxidant
network resulting from increased activity among
the antioxidant within the cell. And second through
the regeneration of other antioxidants by bringing
them back to their reduced antioxidant-potent
form.
Cyanocobalamin: cyanocobalamin
is essential for the maintenance of the integrity
of the nervous system and for the synthesis of
molecules and the production of energy.It has
putative anti-allergic and mood-modulatory activities.
Deficiency of Vitamin B12 results in haemotological,
neurological and gastrointestinal effects such
as pallor of the skin, decreased energy, easy
fatigability, tingling and numbness in the extremities,
visual disturbances, constipation and flatulence.
