1.VC can improve immunity, especially against viruses and prevent diseases such as colds.

2. Promote wound healing and treat oral ulcer and gingival bleeding;

3. Affect vascular permeability and protect cardiovascular system.

So personally, everyone, from children to the elderly, should eat. Just don't have to keep a healthy house. Eating 1.5 yuan's small white tablets every day can achieve the purpose of health care. As far as I am a medical student, the difference between a bottle of expensive vitamins with tens of dollars and a bottle of 1.5 vitamins is nothing more than the following:

1. Expensive effervescent tablets, chewable tablets and buccal tablets are often made into fruits to coax children who don't like taking medicine;

2. Some vitamins are labeled as levorotatory or natural, which is different from synthesis in that they are levorotatory and dextrorotatory, and the dextrorotatory part is not absorbed and passes through the intestine. Therefore, the synthesized 100mg is equivalent to 50mg in the left hand. (Don't write the left hand, but also use racemic form, pure fraud)

3. The expensive ones are all health care product batch numbers, and the 1.5 block is the drug batch number. (At this point, 1.5 yuan's management is stricter and safer. )

4. Some expensive vitamins are made into compound tablets, which is more convenient to take. (but the pertinence is also weak)

If you buy it as a gift, of course, it will be more expensive, and you should eat better things at home all year round. Personally, I think it's good to be cheap.
