美國Douglas Laboratories 硒+維生素 E Selenium + Vitamin E 90粒 軟膠囊

描述
硒 + 維生素 E 每粒明膠軟膠囊提供 268 毫克天然維生素 E 和 50 微克硒.

功能：
維生素E是人體最重要的抗氧化營養素之一。抗氧化劑保護健康細胞免受氧化和自由基的傷害。自由基是一種不穩定的化學物質，在體內新陳代謝過程中以及接觸環境因素（例如污染和香菸煙霧）時產生。自由基是能量代謝和免疫功能所必需的，然而，維持適當的平衡是細胞健康的重要因素，特別是細胞膜脂質和蛋白質。

硒是人類和動物營養必需的微量元素。美國國家研究委員會建議成人每日硒攝取量為55至75微克，視年齡和性別而定。硒是人體內約10種硒蛋白的輔因子，其中最重要的似乎是穀胱甘肽過氧化物酶（GPX）。 GPX利用穀胱甘肽還原過氧化氫，從而保護細胞和血漿免受自由基損傷。 †GPX的活性依賴於足夠的膳食硒供應。最近，硒以硒代半胱氨酸的形式被發現存在於1型和3型碘甲狀腺原氨酸脫碘酶的活性中心，這兩種酶是調節活性甲狀腺激素三碘甲狀腺原氨酸（T3）的重要酶。

建議使用方法
成人每天隨餐服用 1 粒軟膠囊或遵醫囑。

DESCRIPTION
Selenium + Vitamin E, provided by Douglas Laboratories, supply 400 IU ofl vitamin E and 50 mcg of selenium in each gelatin softgel.

FUNCTIONS
Vitamin E is one of the body’s most important antioxidant nutrients. Antioxidants protect healthy cells from oxidative and free radical damage. Free radicals are unstable chemicals formed in the body during metabolism and from exposure to environmental sources, such as pollution and cigarette smoke. Free radicals are necessary for energy metabolism and immune function, however, maintaining an appropriate balance is an important factor for cellular health, especially cell membrane lipids and proteins.

Selenium is a nutritionally essential trace element for humans and animals. The National Research Council’s Recommended Dietary Allowance for selenium in adults ranges from 55 to 75 mcg per day depending on age and gender. Selenium is a cofactor to about 10 selenoproteins in the body; the most important of these appears to be glutathione peroxidase (GPX). GPX uses glutathione to reduce hydrogen peroxide and thus protect cells and plasma against free radical injury.† GPX activity depends on an adequate supply of dietary selenium. Recently, selenium as selenocysteine has been identified in the active center of type 1 and 3 iodothyronine deiodinases, two important enzymes regulating the active thyroid hormone, triiodothyronine (T3).

SUGGESTED USE
Adults take 1 softgel daily with meals or as directed by a healthcare practitioner.
