Synthetic VE is made from petrochemical by-products, which contains chemical intermediates, which is a potential threat to human health and should not be used for a long time. The so-called nature only means that their materials are extracted from natural plants. In fact, this is confusing consumers and deceiving consumers. There are many impurities in health care product VE, and other miscellaneous things are added, which has low purity and will have side effects. In efficacy and safety, it is not as good as natural VE. China has a clear definition of natural vitamin E: China Pharmacopoeia stipulates that the content of 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%. Vitamin E in Yangshengtang says that it contains 97.5 mg of d-α- tocopherol (referring to the content of 250mg per capsule), but it is not clearly indicated on the back that it contains 300 D-α- tocopherol per100g. At present, synthetic VE abroad is only used as feed additive. The purity of d-α- tocopherol in health care product VE is far below 40%. Do not belong to natural VE. The purity is pitifully low. There are many impurities in it. 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 over 96%. Is to meet American standards. Suggestion: you stick it with a toothpick and put it on the back of your hand. If it is oily and not absorbed for a long time, it is fake. If it is absorbed quickly, it is a good vitamin e.
