Vitamin(維生素/維他命)是英文“Vital（至關(guān)重要的）” 和“amines（胺化合物）”的合成詞。
維生素是對我們健康至關(guān)重要的化合物。他們首先被認為是氨基酸，即蛋白質(zhì)的組成成分。今天，我們知道，有13種維生素對人體健康是必不可少的。通常你可以通過(guò)均衡的飲食得到你所需要的所有維生素。但有些人，尤其是那些限制飲食的人，可能會(huì )受益于維生素的額外補充。那你需要補充多少呢？政府已經(jīng)建立了大多數維生素和礦物質(zhì)的建議補充量以及安全上限的指標，我們可以參考。
The word vitamin comes from “Vital” and “amines”
Vitamins are compounds that are vital to our health. They were first thought to be amino acids, the building blocks of protein. Today, we know that 13 vitamins are essential to human health. You can usually get all you need by eating a well-balanced diet. But some people, especially those on restrictive diets, may benefit from vitamin supplements. How much do you need? The government has established recommended daily allowances for most vitamins and minerals, as well as upper limits that are safe.
