Function and harm of selenium

The range between beneficial amount and toxic amount of selenium is the narrowest among all trace elements, so selenium supplementation needs the most technical content, and it will be excessive if you are not careful.

Excessive selenium supplementation will hinder the absorption of manganese by human body, and manganese deficiency will produce a series of health problems. So you can't blindly supplement selenium. Blind selenium supplementation may increase the risk of some diseases. If you especially want to supplement selenium, you must also pay attention to the right amount, and you can't blindly supplement selenium.

Excessive selenium will harm health and lead to selenium poisoning, such as hair loss, blackening of nails and skin, etc., so it is not necessary to supplement selenium blindly.

It is generally recommended that the daily intake of selenium is 50-250μg, and the upper limit of daily tolerance intake is 400 μg g. Adults generally take 50μg of selenium every day to meet their needs.

Extended data:

The human body cannot synthesize selenium by itself, and food is the main source of selenium. A healthy person who is not partial to food or picky eaters can meet the body's demand for selenium through a balanced diet without additional supplements.

All kinds of selenium-enriched foods sold in the market, such as selenium-enriched rice and selenium-enriched vegetables, can be eaten occasionally, and there is no need to buy them often. If you must eat selenium-enriched food, you'd better choose the one marked with selenium concentration, and then buy it after calculating your body requirements.

In natural foods, the selenium content from high to low is: animal viscera, seafood, fish, eggs, meat, grains, milk, onions, garlic, vegetables and fruits. Sesame and garlic also contain a lot of selenium. The selenium content of the same crop varies greatly in different regions, with a difference of thousands or even tens of thousands of times.
