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%.
The purity of VE in Yangshengtang is only 39%. The purity of Amway is similar. There are many messy and exciting things in it.
