It is not really 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%, which is unnatural.
Vitamin E supplement: Of course, it is good for people who lack vitamin E, but it is also good for people who do not lack vitamin E.
Taking too much is harmful to your health. So whether it is harmful depends on whether you really need to supplement it.
