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 foods, and no amount of them will have obvious effects. All kinds of false advertisements that exaggerate the effect dazzle you. The price is still too expensive. Pure natural vitamin E belongs to OTC drugs, which conforms to the national GMP management standards and has a strict production process, which is safer and more reliable. 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 each 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 products capsules are also filled with many impurities. The tocopherol purity of health care product VE is generally much lower than 40%. If a vitamin E capsule indicates that each capsule contains 97.5 mg of d-α- tocopherol, and each capsule weighs 250 mg (40 g/160 capsules), two capsules should be used. Personally, I think it must be right to eat high-purity food. Just like the milk storm that made a lot of noise some time ago, it is reassuring to eat real high-purity pure milk, but it is always disturbing to eat low-purity milk mixed with other substances, let alone milk mixed with melamine. China's national laws and regulations have a clear definition of pure natural vitamin E: China Pharmacopoeia stipulates that the purity of pure natural vitamin E :D-α- tocopherol shall not be less than 90%, and the United States Pharmacopoeia stipulates that the purity shall not be less than 96%. Limited by technical ability, the purity of natural VE of health food symbols on the market is less than 50%. Strictly speaking, there are only three pure natural VE in China. The purity of d-α- tocopherol is more than 96% of Lion natural vitamin E. Meet American standards.
