    Product Introduction:

    α- Lipoic acid is a pale yellow powdery crystal that is almost odorless. The solubility in water is small, about 1 g/L (20 ° C). Soluble in 10% NaOH solution, soluble in aliphatic solvents.

    Also known as lipoic acid α- Lipoic acid.

    Lipoic acid has a chiral center and therefore has two configurations, R and S.

    Natural lipoic acid is a white crystal with only R configuration, and only R configuration lipoic acid can be covalently conjugated to lysine residues through amide bonds to perform coenzyme functions.

    The artificially synthesized lipoic acid is a mixture of equal proportions of R and S configurations, which is a pale yellow powdery substance that is extremely soluble in lipid solvents.

    Product Function:

    1. Stabilization of blood glucose values
    Since it was used as a medicine to treat diabetes at the beginning, of course it will have such a function. In fact, lipoic acid is mainly used to prevent sugar from combining with protein, that is, it has the effect of "anti saccharification", so it can easily stabilize the blood sugar value. Therefore, lipoic acid was previously used as a vitamin to improve metabolism, and it was used by patients with liver diseases and diabetes patients.

    2. Strengthen liver function
    Lipoic acid has the function of strengthening liver activity, so it was also used as an antidote for food poisoning or metal poisoning in the early stage.

    3. Recovery from fatigue
    Because lipoic acid can improve the energy metabolism rate and effectively convert food eaten into energy, it can quickly eliminate fatigue and make the body feel less tired.

    4. Improve dementia
    The constituent molecules of lipoic acid are relatively small, so it is one of the few nutrients that can reach the brain. It also maintains antioxidant activity in the brain and is considered to be quite effective in improving dementia.

    5. Protect the body
    In Europe, research has been conducted specifically on lipoic acid as an antioxidant, and it has been found that lipoic acid can protect the liver and heart from damage, inhibit the occurrence of cancer cells in the body, and alleviate allergies, arthritis, and asthma caused by inflammation in the body.

    6. Beauty and anti-aging
    Lipoic acid has an amazing antioxidant capacity, which can remove the active oxygen components that cause skin aging. Due to its smaller molecule than vitamin E, and its combination of water and fat solubility, it is quite easy to absorb through the skin.
