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 purity of pure natural vitamin E :D-α- tocopherol shall not be less than 90%, and the United States Pharmacopoeia stipulates that the purity shall not be less than 96%.

Strictly speaking, there are only three pure natural VE in China: Lion, Double Whale and Fang Quan. The purity of d-α- tocopherol of Lion brand natural vitamin E is more than 96%. Meet American standards.
