If you want to choose health care products for long-term oral administration, the national definition of health care products is that they can be taken for a long time and must be non-toxic, while drugs cannot be taken for a long time. Taking large doses of vitamin E for a long time can cause various diseases. The mask can choose medicine, which is economical and affordable. Personally, I think Yangshengtang is the first choice for internal use, and Double Whale is the first choice for external use, because Double Whale is an old brand. In addition, vitamin E of a medicine is also good for Dalian Orson, and the medicine can also be taken, but it can't exceed 70 days at most, that is, ten weeks.
