Introduction：
Product name | Alpha lipoic acid |
Synonyms | Thioctic acid, Lipoic acid |
Grade | Food, Granular, Solvent free grade. |
Appearance | Slightly yellow crystal powder |
CAS No. | 1077-28-7 |
Molecular formula | C8H14O2S2 |
Molecular weight | 206.33 |
Purity | 99.0%min Alpha lipoic acid |
Particle size | 100% through 40 mesh |
Alpha lipoic acid is a unique anti-free radical substance often referred to as a broad antioxidant. It is a vitamin-like substance produced in the body. Unlike other antioxidants produced in the body that have specific roles, lipoic acid is neither strictly fat-soluble nor water-soluble, which allows it to promote the activity of other antioxidants in the body, as well as being a widely available substitute when antioxidants are insufficient.

Function and Application:
1. Alpha lipoic acid has also been used as an antidote to food poisoning and metal poisoning since it strengthens liver activity.r alpha lipoic acid sodium is also often used in the nutraceutical industry.
2. The constituent molecules of lipoic acid are quite small and are one of the few nutrients that can reach the brain, where it sustains antioxidant activity and is considered effective in improving dementia, which is why alpha lipoic acid powder is often used as a nutraceutical ingredient.
3. Since alpha lipoic acid increases energy metabolism and efficiently converts eaten food into energy, it can quickly eliminate fatigue and make the body feel less tired.
4. In Europe, studies have been done specifically on the part of R alpha lipoic acid as an antioxidant, and it has been found that alpha lipoic acid protects against liver and heart damage, inhibits the development of cancer cells in the body, and eases the body's inflammation-induced allergies, arthritis, and asthma.
5. Alpha lipoic acid has amazing antioxidant properties, removes the reactive oxygen species that are responsible for skin ageing, and because it is a smaller molecule than Vitamin E, and is both water and fat soluble, it is readily absorbed by the skin. It is particularly effective in improving the appearance of dark circles, wrinkles and blemishes, and by strengthening metabolism, the body's blood circulation will improve, improving dullness and reducing the size of pores, resulting in enviable skin.Bulk alpha lipoic acid sells well.
