The effect of natural VC is better than that of synthetic VC. At present, the raw materials of natural VC on the market are mostly from West Indian cherries, and the two representative brands are Yangshengtang and Nutrilite. It is worth mentioning that Nutrilite natural VC not only contains VC from West Indian cherry, but also contains citrus extract, and the flavonoids contained in it can better protect VC and enhance its antioxidant effect. You can compare the cost performance of the two products before making a decision. One more thing, all the plant raw materials of Nutrilite products come from Nutrilite organic farm, so there is no hidden danger of raw material safety.
