Fancl's vitamins are better I think it depends on different people. I feel that products without additives are good, pure and natural. However, taking oral products is a very slow and long process, and it takes about 3-6 months to see some effect.

Vitamin C is the most easily oxidized component in nature, which is difficult to preserve! I don't think it's artificial! It is better to eat more fruits and vegetables!

In addition, if it is not the lack of such substances in the body, it will have side effects if it is supplemented! For example, vitamin E, which we all think is a good thing, is antioxidant, but if it is supplemented too much, there will be a risk of breast disease!
