English Name:DL-Lipoic Acid;α-Lipoic Acid; CAS NO: 1077-28-7; Molecular formula:C8H14O2S2 DL lipoic acid is a unique anti free radical substance, which is often referred to as a wide range of antioxidants. It is a vitamin like substance produced in the body. Unlike other antioxidants with special effects produced in the body, DL lipoic acid is neither strictly fat soluble nor water-soluble, which makes it possible to promote the activity of other antioxidants in the body, and it is also a widely available substitute when antioxidants are insufficient. For example, if the contents of vitamin C and vitamin E stored in the chemical book are very low, DL lipoic acid can be temporarily supplemented. Because DL lipoic acid can pass through the blood-brain barrier, it can help reverse the adverse reactions caused by stroke. DL lipoic acid also helps to maintain the normal level of blood sugar and prevent serious complications of diabetes. With age, the human body will not be able to produce enough DL lipoic acid to maintain health.
