Can taking health supplements improve immunity?

There is a very important principle in nutrition that as long as various nutrients can be obtained from daily diet, it is not recommended to take health supplements. For example, for a normal person, the recommended daily intake of vitamin C is 100 mg. Eating a 250g fruit, such as kiwi, orange, etc., can basically meet the demand, and there is no need to take additional health supplements. During the epidemic, even if you want to supplement more vitamin C, eating two fruits a day is enough.

Some elderly people or people with underlying diseases may want to supplement their diet with health supplements because they dare not or cannot eat fruit. However, you must understand that although health supplements contain sufficient doses of vitamin C, their nutritional value is definitely not as good as eating natural fruits.

Therefore, everyone must pay attention to the fact that the most recommended way to get various nutrients is through dietary supplementation. It is only meaningful to take health supplements when you cannot get enough nutrients through diet.

The vitamin C mentioned here is a special nutrient, because many studies have shown that high doses of vitamin C can help people fight influenza, so can we supplement some high doses of vitamin C in addition to meals to further enhance immunity? It is recommended that if you are a healthy person, it is no problem to supplement with large doses of vitamin C in the short term. However, if you suffer from some chronic diseases, you should ask your doctor whether you can supplement with large amounts of vitamin C.

Generally speaking, any medicine, including health food, is different from normal diet. Taking medicine for a long time or in large doses may affect your health. This is why doctors always emphasize the need to carefully choose health products, preferably under the guidance of a doctor or clinical nutritionist.

my country defines health care products as foods that have certain health care functions but are not intended to treat diseases. Since they are not medicines, don't expect health care products to cure diseases or have magical effects. The role of health care products is to supplement the deficiencies of the diet, but don't take too much at a time to avoid damaging the body.
