LIPOIC ACID APPLICATION



1.Lipoic acid is a B vitamin that can stop the glycosylation of proteins and inhibit aldose reductase, preventing the conversion of glucose or galactose into sorbitol, so it is mainly used for the treatment and relief of peripheral neuropathy caused by advanced diabetes.


2. Lipoic acid is a super-powerful antioxidant, which can preserve and regenerate other antioxidants, such as vitamin C and E, and balance blood sugar concentration, effectively enhance the Chemicalbook immune system in the body from the damage of free radicals, participate in energy metabolism, increase the ability of other antioxidants to destroy free radicals, promote the restoration of insulin sensitivity, enhance the body's ability to gain muscle and lose fat, activate Cell, anti-aging and beauty.


3. Lipoic acid can strengthen the function of liver activity, so that the energy metabolism rate increases, and make the food we eat quickly into energy, eliminate fatigue, so that the body does not easily feel tired.
