I'm a medical student, and I really tell you, natural vitamins, VCVE, etc. Yangshengtang does the best. The auxiliary materials are authentic and easy to get. Amway's will do. Vitamins are not suitable for making precious powder, because powder is easy to be oxidized, so it is inevitable to add preservatives, flavor pigments and flavoring agents. Moreover, VC is easy to oxidize when it meets hot water. It is not convenient for girls to soak things in cold water every day.

Vitamin supplementation is not as good as taking medicine directly. The auxiliary materials of VC tablets are basically cellulose and starch, and there are no side effects at all. As for some people, the powder is easily absorbed-you can try putting it in water for 3 minutes to ensure that it is completely disintegrated into fine powder and VC is completely soluble in water. So this absorption gap is almost non-existent.

And these things, if bought on Taobao, are almost 100% fakes. DHC takes all holidays except the counter and official website. Moreover, fakes are beautiful, and unless they are really compared, they can't be seen as fakes at all. (experience! ! The lesson of blood! ! A bottle of 1.5 synthesized by VC, since it costs a lot of money to buy insurance, don't buy it on Taobao. Go to the health counter of the drugstore. At present, the most famous and authentic natural vitamins are nothing more than Yangshengtang and Amway, so you can choose.
