The natural vitamin E in Yangshengtang is said to contain 97.5 mg of d-α- tocopherol (referring to the content of 250mg per capsule), but the back is not obvious. Every 100 g contains 39 g of d-α- tocopherol, and the actual purity 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 shall not be less than 90%. Compared with the national regulations, the content is less than 90%, which is not natural vitamin E at all. It says that its material is extracted from natural plants and is natural VE. In fact, this is confusing consumers and deceiving consumers. Most people don't know how to distinguish "synthetic VE" from "natural VE". TV commercials and packaging all say it is natural vitamin E, thinking it is.
