Alpha Lipoic acid is a vitamin drugs, limited physical activity in its dextral, basically no physical activity in its Lipoic acid, and no side effects. It is always used for acute and chronic hepatitis, liver cirrhosis, hepatic coma, fatty liver, diabetes, Alzheimer's disease, and applies as an antioxidant health products.


1.Alpha Lipoic Acid is a coenzyme, and one of the most powerful antioxidants. It is referred to as the universal antioxidant because it is water and fat soluble, enabling it to function in both the membrane and aqueous parts of cells, to help fight cell damaging free radicals in the body

2.Alpha Lipoic Acid supports the regeneration of glutathione, one of the bodys primary antioxidants and helps to recycle glutathione, Vitamin C and E, and Coenzyme Q10

Alpha Lipoic Acid (also known as lipoic acid, thioctic acid, or ALA) is one of the good fatty acids produced in every one of our cells. One of its main functions is to help convert glucose (blood sugar) into energy. About forty years ago, biologists discovered that ALA is also an antioxidant—a powerful substance that combats potentially harmful chemicals called free radicals which may cause heart and liver disease, cancer, cell aging, and many other conditions.

Alpha-lipoic acid is used for diabetesand nerve-related symptoms of diabetesincluding

Burning, pain, and numbness in the legs and arms. High doses of alpha-lipoic acid are approved in Germany for the treatment of these symptoms. Alpha-lipoic acid is also used to treat eye-related disorders, such as damage to the retina,cataractsglaucoma, and an eye disease called Wilson’s disease.


Alpha lipoic acid can help with the following conditions:

  • Hypertension (High Blood Pressure)
  • Coronary Heart Disease
  • Metabolic Syndrome (high blood pressure and elevated cholesterol
  • Peripheral Neuropathy (caused by diabetes and other conditions, such as Lyme disease, alcoholism, shingles, thyroid disease and kidney failure)
  • Diabetes (improving glucose metabolism and helping diabetics utilize insulin better)
  • Liver Disease
  • Metastatic Pancreatic Cancer (increasing long-term survival)
  • Impaired Brain Function (as a treatment for stroke and other brain disorders involving free radical damage, including Alzheimer's disease)
  • Effects of Aging (improving blood flow and enhancing immune function, restoring levels of glutathione, a protective antioxidant and detoxification compound)
  • Degenerative Diseases (ALA is a strong anti-inflammatory agent)
  • Glaucoma and Cataract



Alpha-lipoic acid is a vitamin-like chemical called an antioxidant. Yeast, liver, kidney, spinach, broccoli, and potatoes are good sources of alpha-lipoic acid. It is also made in the laboratory for use as medicine.


Alpha-lipoic acid is used for diabetes and nerve-related symptoms of diabetes including burning, pain, and numbness in the legs and arms. High doses of alpha-lipoic acid are approved in Germany for the treatment of these symptoms.


Some people use alpha-lipoic acid for memory loss, chronic fatigue syndrome (CFS), HIV/AIDS, cancer, liver disease, diseases of the heart and blood vessels (including a disorder called cardiac autonomic neuropathy) and Lyme disease.


Alpha-lipoic acid is also used to treat eye-related disorders, such as damage to the retina, cataracts, glaucoma, and an eye disease called Wilson’s disease.

How does it work?
Alpha-lipoic acid seems to help prevent certain kinds of cell damage in the body, and also restores vitamin levels such as vitamin E and vitamin C. There is also evidence that alpha-lipoic acid can improve the function and conduction of neurons in diabetes.


Alpha-lipoic acid is used in the body to break down carbohydrates and to make energy for the other organs in the body.


Alpha-lipoic acid seems to work as an antioxidant, which means that it might provide protection to the brain under conditions of damage or injury. The antioxidant effects might also be helpful in certain liver diseases.


Function of Alpha Lipoic Acid Powder:
1. Alpha lipoic acid powder is a fatty acid found naturally inside every cell in the body.
2. Alpha lipoic acid powder is needed by the body to produce the energy for our body's normal functions.
3. Alpha lipoic acid powder converts glucose(blood sugar) into energy.
4. Alpha lipoic acid powder is also an antioxidant, a substance that neutralizes potentially harmful chemicals called free radicals. What makes alpha lipoic acid powder unique is that it functions in water and fat.
5. Alpha lipoic acid powder appears to be able to recycle antioxidants such as vitamin C and glutathione after they have been used up. Alpha lipoic acid powder increases the formation of glutathione.
