Beta carotene in itself is not an essential nutrient, but vi-ta-min A is. Beta carotene’s chemical formula – C40H56 – was discovered in 1907

vitamin A can be sourced from the food we eat, through beta carotene, for example, or in supplement form. The advantage of dietary beta carotene is that the toàn thân only converts as much as it needs.

Excess vi-ta-min A is toxic. Toxic vi-ta-min A levels can occur if you consume too many supplements.


Uses và benefits of beta carotene

There are a number of ways that beta carotene can benefit human health. Below, we give some examples:

Beta carotene is an antioxidant

Beta carotene, lượt thích all carotenoids, is an antioxidant. An antioxidant is a substance that inhibits the oxidation of other molecules; it protects the body from miễn phí radicals.

Beta carotene may slow down cognitive decline

Men who have been taking beta carotene supplements for 15 or more years are considerably less likely lớn experience cognitive decline than other males, researchers from Harvard Medical School reported in Archives of Internal Medicine (November 2007 issue).

Over the short-term, they found no difference in cognitive decline risk between the two groups of men, but in the long-term it was clear that beta carotene supplements made a significant difference.

Beta carotene keeps lungs healthy as people age

The BMJ published a report in March 2006 which showed that high blood beta carotene levels compensate for some of the damage to the lungs caused by oxygen free radicals.

They measured the FEV1 of 535 participants and measured their beta carotene blood levels. FEV1 measures how much air you can breathe out in one go. They found that those with high beta carotene levels had much slower decline in FEV1 measures.
