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%.
