China's national laws and regulations have a clear definition of pure natural vitamin E: China Pharmacopoeia stipulates that the content of natural vitamin E :D-α- tocopherol should not be less than 90%, and the United States Pharmacopoeia stipulates that it should not be less than 96%. Vitamin E in Yangshengtang says that it contains 97.5 mg of d-α- tocopherol (referring to the content of 250mg per capsule), but the back does not obviously contain 39 g of d-α- tocopherol per 100 g, and the actual purity is only 39%. Amway Nutrilite is said to be extracted from natural wheat germ, each grain contains vitamin E 18mg, with a net content of 44g/ grain (100 grain), and the actual purity is only 4.09%. The purity of d-α- tocopherol in health care product VE is far below 40%. The purity is pitifully low. There are many impurities in it. Strictly speaking, there are only three natural VE in China, Lion, Double Whale and Fang Quan. The purity of Lion brand natural vitamin E is over 96%. Is to meet American standards.
