If you want to have a good effect and no side effects, I suggest you use pure natural vitamin E. Pure natural vitamin E is extracted from natural vegetable oil, so it is harmless to human body and has no side effects, and can be used for a long time. However, the synthesis of VE is based on petrochemical by-products, and there are chemical intermediates, which are potential threats to human health and are not suitable for use.

China has a clear definition of pure natural vitamin E:

China Pharmacopoeia stipulates that the content of pure 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%. The purity of VE in Yangshengtang is only 39%, which is not within the scope of pure natural VE.

Strictly speaking, at present, there are only three pure natural VE in China, and the purity of Double Whale and Fang Quan is only 90%, reaching the national standard. The purity of Lion brand natural vitamin E is more than 96%. Is to meet American standards.
