The more vitamins you take, the better?

Vitamins are essential nutrients for the human body, so many people feel that they should take more supplements if they have nothing to do. Because of this, there are many people around us who buy various vitamin supplements, and they also have doubts about how to choose them.

However, in today's affluent material life, most vitamins can actually be satisfied through food.

Many vitamins are unnecessary

The human body needs 13 kinds of vitamins, including vitamin C, 8 kinds of vitamin B (commonly referred to as "B vitamins"), and 4 kinds of fat soluble vitamins - vitamin A/D/E/K.

These vitamins have a wide range of sources in food, such as:

Animal foods such as liver, milk and egg yolk are rich in vitamin A;

Orange yellow food such as carrots and pumpkins and dark green food such as kale and spinach, rich in β- Carrots can be converted into vitamin A in the body;

Cereals, meat, fish, milk and various edible oils are rich in vitamin E;

Cereals, beans and coarse cereals contain rich B vitamins.

In a word, the human body has a small demand for most vitamins, which can be basically met from food without additional supplement. Of course, if you always eat takeout, your diet is not very balanced, and there is no harm in taking vitamins.

The more vitamins you take, the better

Take fat soluble vitamin A/D/E/K for example, it is easy to accumulate in the human body, and excessive intake may lead to adverse consequences. For example, excessive intake of vitamin A during pregnancy may cause malformation, and excessive intake of vitamin E may cause death.

For water-soluble vitamin C, excessive intake may increase the risk of kidney stones.

However, don't worry too much. Even if you take additional supplements, as long as the recommended dosage in the manual is not exceeded, there will be no major problem.

However, in order to cater to children's taste, the popular multivitamins in recent years have also been specially made into soft candy, fruit juice and other forms. But it is easy to cause children to take too much, and the high sugar intake will also cause hidden danger to the child's tooth development.

Vitamin D may be what you need most

Vitamin D is closely related to bone health, but its content in breast milk and various foods is relatively low, so most people are deficient in vitamin D.

Although, to some extent, sun exposure can promote the synthesis of vitamin D in the body, we go out early and come home late, armed, and basically not enough sun exposure. Even if we really want to get enough sunshine, ultraviolet rays will also cause damage to our eyes and skin. Therefore, it is very necessary to add vitamin D to weigh the advantages and disadvantages.

Adults need 400 IU vitamin D every day, and over 65 years old need 600 IU vitamin D (for vitamin D, 1 IU=0.025 microgram). We can see the vitamin D content of the product on the package of the vitamin D product.
