Everyone may have encountered this situation, that is, when you go to the drugstore to buy vitamin C, the clerk will always take out a bottle of chewable tablets of vitamin C above 98 from the back cabinet and claim that it is pure natural. If you say that you only want a two-yuan white bottle of vitamin C, the clerk will say that it is an industrial synthesis, which is not good for people's health.

So, is there a difference between a bottle of vitamin C for two dollars and a bottle of vitamin C for one hundred dollars? Yes, that's so different!

First of all, the 100 yuan vitamin C chewable tablets are generally health care products, and the bottles have food safety labels, while the two-yuan bottles of vitamin C are printed with otc drug labels. Otc's review standard is much stricter than that of health food, and there will be strict requirements on the production standard and residue of drugs.

Natural extraction of expensive VC and industrial synthesis of cheap VC? Actually, they are not. Through chemical tests, they will find that their structural formulas are actually the same. That means there is no difference between the main components of expensive vc and cheap vc, but your vc has become an expensive "sugar-coated cannonball" through packaging, dextrin, sugar and so on. In addition, there is an interesting experiment, and the vc content of health care products is much less than the labeled vc content. (Excerpted from Tencent. com)

Conclusion: Both of them have the same composition of vitamin C (the chemical molecular formula is the same, but there is no difference in the absorption of the same human body), while a bottle of 2 yuan has a high VC content, so it is mainly used for drug treatment; The VC content of health care products is relatively low, so they can be taken for a long time.

Remember: vitamin C can be supplemented in moderation, but not in excess, otherwise the effect may be counterproductive, and excessive supplementation may lead to lithiasis.
