Yangshengtang says it is pure natural VC, but I can tell you for sure after eating it, it is not pure natural at all, obviously not the natural fragrance of cherry. That VE also has a safflower ingredient more than normal VE, which promotes blood circulation. Not everyone is suitable, so don't watch advertisements. Watson's products have not been eaten, so I dare not say more. In fact, I think you might as well go to the drug counter (non-health product counter) of a drugstore and buy natural VE and a small bottle of yellow VC made in Shandong or Dalian directly.
