Brief Introduction:
DL-α-Tocopherol, the chemical name is (2S)-2,5,7,8-tetramethyl-2-[(4S,8S)-4,8,12-trimethyltridecyl]-3,4-dihydro-2H-chromen-6-ol or (2R)-2,5,7,8-tetramethyl-2-[(4R,8S)-4,8,12-trimethyltridecyl]-3,4-dihydro-2H-chromen-6-ol, also known as vitamin E alcohol, is a class of compounds that mainly exhibits vitamin E activity.
Because its vitamin activity was first identified in 1936 in experiments on reproductive factors in rats, it was named "tocopherol". Found in edible oils, fruits, vegetables and grains, it is a fat-soluble vitamin and an important antioxidant. Similar substances of DL-α-tocopherol include: d-α-tocopherol; d-α-tocopherol ester; dl-α-tocopherol ester; d-α-tocopherol hydrogen succinate; dl-hydrogen succinate α-Tocopherol ester; β-tocopherol; γ-tocopherol; δ-tocopherol, all of them have the physiological activity of vitamin E, among which DL-α-tocopherol has the greatest activity and the strongest antioxidant capacity.

Main Functions:
♔ Vitamin E is a highly effective antioxidant that protects cell membranes from free radical damage and protects blood vessels, heart, breasts, eyes, skin, glands and other organs. This can prevent a variety of chronic diseases, such as breast cancer, cardiovascular disease, rectal cancer, etc.;
♔ Promote protein renewal and synthesis, which can promote wound healing;
♔ Promote the proliferation of capillaries and small blood vessels, improve peripheral blood circulation, and increase the supply of oxygen to tissues, thereby creating good nutritional conditions for ulcer healing;
♔ Related to reproductive function and sperm production, preventing miscarriage, infertility, and maintaining ovaries;
♔ Protect red blood cell membranes and prevent hemolytic anemia;
♔ Whitening and freckle removal, hair care, sun protection and skin care;
♔ Improve immune function and delay aging;
♔ Inhibit the growth of Helicobacter pylori and reduce the recurrence rate of ulcers after healing.
