Alpha Lipoic Acid:
Alpha-lipoic acid, also known as lipoic acid, is an anitioxidant with an important rejuvenating function in the body. As antioxidants deplete as they neutralize free radicals, lipoic acid reenergizes them by restoring vitamins A and E and glutathione. Through a balanced and healthy diet, the body can produce sufficient supplies of alpha, although it is also taken as a dietary supplement.
Alpha has many beneficial properties, including the ability to stimulate insulin and lower blood sugar levels. These attributes make it useful in treatments for diabetes, nerve problems, liver disease, AIDS and eye-r elated problems, including glaucoma and cataracts. Through gene regulation, Alpha may prevent or prolong asthersclerosis.
As an antioxidant, Alpha helps prevent the damaging effects of free radicals—waste products that are produced when food is turned into energy. Alpha, which recycles vitamins C and E to provide antioxidant protection, is an overall immune system booster that can help ward off many illnesses. It also repairs cell damage by promoting energy production in cells. In Europe, Alpha is used to reduce symptoms of diabetes, including pain, itching, and burning.
Insufficient levels of Alpha may result in immune and gastrointestinal dysfunctions, birth defects and delayed maturation. A number of conditions may arise that negatively affect the natural production of Alpha, including rare genetic disorders and high stress and trauma conditions that impair the synthesis of Alpha.
Alpha can be obtained through dietary sources, including broccoli, spinach, potatoes, liver, kidney and yeast.
It is recommended that Alpha be taken in balance with other amino acids. For an adult, the daily required dosage is 50 to 100 milligrams. The metabolism of alpha may be improved by combining it with other nutrient supplements, such as B vitamins.
