Lipoic acid (LA), also known as α-lipoic acid ,alpha lipoic acid (ALA) ,thioctic acid is an organosulfur compound derived from octanoic acid. alpha lipoic acid is made in animals normally, and is essential for aerobic metabolism. It is also manufactured and is available as a dietary supplement in some countries where it is marketed as an antioxidant, and is available as a pharmaceutical drug in other countries.
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. Alpha lipoic acid is always used for acute and chronic hepatitis, liver cirrhosis, hepatic coma, fatty liver, diabetes, Alzheimer's disease ,and applies etc .
1. A necessary substance for our body, produce the energy for our body's normal functions and convert glucose(blood sugar) into energy.
2. Used to antioxidant,to be able to recycle antioxidants such as vitamin C and glutathione after they have been used up. AlA the formation of glutathione.
3. Improve the growth performance and meat performance to increase economic benefits.
4. To be coordination of the metabolism of Sugar, Fat and Amino Acid to improve animal immune function.
5. Used to protect and promote the absorption and transformation of VA, VE and other oxidation nutrients .
6. Effectively ensure and improve the production performance of livestock and poultry and egg production in heat-stress environment.
