It is very important to choose what kind of VE, because there are many kinds of vitamin E products on the market at present, and people can choose a wide range. There are two kinds of vitamin E: synthetic and natural, medical quasi-word VE and health care product VE. There is a big difference. Many health care products VE are simply food, and no amount of them will have obvious effect. All kinds of false advertisements that exaggerate the effect dazzle you. The price is still too expensive. The effect of vitamin E capsule depends on the content of VE in the capsule. You only need to look at the content of VE in its target capsule, that is, the content of d-α- tocopherol. If it is very low, this VE capsule is not good. Although the names are all called vitamin E capsules, they are very different, because many VE capsules are not all VE ingredients, and many health care capsules are filled with many impurities. For example, in the much-publicized Yangshengtang, the purity of VE is only 39%. China's national laws and regulations have a clear definition of 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%. Strictly speaking, there are only three kinds of natural VE in China, and the purity of the two whales and the whole formula is only 90%, which meets the national standard. The purity of Lion brand natural vitamin E is more than 96%. Is to meet American standards.
