If you want a good effect and no side effects, I suggest you use pure natural vitamin E, because pure natural vitamin E is extracted from natural vegetable oil, which is harmless to human body and can be used for a long time. However, synthetic VE is made of petrochemical by-products and contains chemical intermediates, which is a potential threat to human health and is not suitable for use.

China's national laws and regulations have 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%.

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