Alpha lipoic acid is a drug that is also known as an antioxidant. In orthodox medicine, alpha lipoic acid is prescribed for many diseases. Since alpha lipoic acid is only absorbed through a few foods, such as potatoes, spinach and red meat, researchers recommend taking alpha lipoic acid as a dietary supplement.

Drugstore articles: Alpha lipoic acid Video Guide

Alpha lipoic acid contains two sulfur atoms that can be reversibly reduced and oxidized. Alpha lipoic acid not only has the properties of an antioxidant, but is also a co-factor for several essential enzymes. Alpha lipoic acid exists in two optical isomers, R-alpha lipoic acid and S-alpha lipoic acid. These have different characteristics. Optical isomers are the main differences between these two forms that direct polarized light in opposite directions. From a chemical point of view, these two forms of alpha lipoic acid are difficult to separate because they are identical. However, the molecules are mirror-inverted, similar to the right and left hands of a pair of gloves.

R-alpha-lipoic acid is considered to be the better form of alpha-lipoic acid as it is a natural, endogenous form. However, inexpensive dietary supplements contain a small amount of R-alpha-lipoic acid. Instead, up to 90 percent of S-alpha-lipoic acid is used in preparations containing synthetic isomers. The differences between R-alpha-lipoic acid and S-alpha-lipoic acid can be seen in their three-dimensional structure. A health-promoting effect is only achieved with the R-form of alpha lipoic acid. Researchers assume that S-alpha-lipoic acid does not fulfil any function for the body and even has a rather harmful effect, since the S-form counteracts the positive effect of the R-form. For this reason you should choose a dietary supplement that contains at least a 1:1 mixture of natural and synthetic alpha lipoic acid. Since the production costs for preparations with R-alpha-lipoic acid are about eleven times as high as for an equally divided mixture, high-quality food supplements are rare and, if so, expensive to obtain.

Alpha lipoic acid is available as a dietary supplement and as a medicine. Supplements that are synthetic are usually added. If high-quality, natural R-alpha-lipoic acid is taken, it can be better absorbed, metabolized and excreted by the body. Since alpha lipoic acid does not remain in the body for long, high doses should be taken throughout the day to achieve a more effective effect. Alpha lipoic acid is usually administered orally. This form of intake reduces oxidative stress. However, if there is a pronounced deficiency of alpha lipoic acid, the doctor may also prescribe high-dose intravenous administration.

Alpha lipoic acid is used for very specific diseases in orthomolecular therapy. Diabetes is one of these diseases, as alpha lipoic acid optimizes glucose tolerance and thus improves the diabetic condition. In this case, oral or high-dose intravenous administration may be used. Alpha lipoic acid is also prescribed for dementia diseases, as this substance contributes to maintaining the health of brain cells. In cancer, alpha lipoic acid can help repair damaged cell structures due to its activating and antioxidant properties. In the case of chronic fatigue syndrome, alpha lipoic acid is also prescribed. This disease is caused by a disturbed energy metabolism that takes place in the mitochondria. This energy metabolism is stimulated by alpha lipoic acid and thus leads to an improvement of the symptoms. The well-known but very rare side effects of alpha lipoic acid include headaches, visual disturbances, increased sweating, vomiting, nausea and diarrhoea. Also taste disorders and hypersensitivity disorders can occur in very rare cases.
