Although many domestic health care products VE are called vitamin E capsules, there are great differences, because many VE capsules are not all VE ingredients, and many health care products capsules are also filled with many impurities.
China has a clear definition of pure natural vitamin E:
China Pharmacopoeia stipulates that the content of pure natural vitamin E :D-α- tocopherol shall not be less than 90%, and the United States Pharmacopoeia stipulates that it shall not be less than 96%.
Yangshengtang Vitamin E says that it contains 97.5 mg of d-α- tocopherol (referring to the content of 250mg per capsule), but the back does not clearly show that it contains 39 g of d-α- tocopherol per kloc-0/00g, and the actual purity is only 39%, which is unnatural.
