維生素B7的名稱來源於德語「Biotin」，意味著生命之源，這是因為維生素B7在生物體的生長和維持健康中扮演著不可或缺的角色。雖然人體需求量不大，但每天補充仍是必要的！

維生素B7不僅促進健康的頭髮、皮膚和指甲成長，也是碳水化合物、脂肪和蛋白質代謝中的關鍵輔酶，有助於維持穩定的血糖水平，並提升身體對壓力的應對能力。立即花幾分鐘了解維生素B7如何助你維持生命活力與健康！

維生素B7是什麼？

維生素B7，又稱生物素，是水溶性維生素，屬於B群維生素的一員，普遍存在於許多食物中。維生素B7在身體的碳水化合物、脂肪和蛋白質代謝過程中起著關鍵作用。

生物素的主要功能之一是作為多種酶系統的必需組分，特別是那些參與脂肪酸的合成和分解的酶。這使得維生素B7對於維持能量生產和身體正常功能是不可或缺的營養素。

此外，維生素B7對於促進健康的皮膚、頭髮和指甲的生長至關重要。它還參與合成神經傳導物質和遺傳物質（如DNA），在維持神經系統的健康和細胞分裂過程中發揮關鍵作用。

為什麼要補充維生素B7？探索其6大功效

1.促進健康的頭髮、皮膚和指甲：生物素對於保持健康的皮膚、頭髮和指甲有顯著作用，幫助減少斷裂和脫落，提升其整體外觀和質感。

2. 支持代謝功能：維生素B7是多種代謝反應的必需輔酶，有助於食物中脂肪、蛋白質和碳水化合物的正常代謝，從而轉化為身體可利用的能量。

3. 改善血糖控制：研究表明，生物素可以幫助維持穩定的血糖水平，尤其是對於糖尿病患者來說，補充生物素可能對控制血糖有益。

4. 支持神經功能：維生素B7對於神經健康至關重要，尤其是在合成影響神經傳遞的關鍵神經傳導物質方面。

5. 胚胎發育：對於孕婦來說，生物素在確保胚胎正常發育的過程中扮演著重要角色，特別是在早期胎兒的生長和發育階段。

6. 增強皮膚防禦機能：維生素B7有助於維持皮膚的屏障功能，保護皮膚免受環境壓力和病原體的侵害。

維生素B7在人體內的儲存時間


當我們攝取維生素B7後，它在體內經過消化系統的吸收，進入血液循環中發揮作用。維生素B7的生理半衰期約為2至4小時，意味著一半的攝入量會在這段時間內代謝或排出。因此，需要定期攝取含有維生素B7的食物以維持其生理功能，如幫助脂肪酸和氨基酸的代謝，以及維持皮膚、頭髮和指甲的健康。

缺乏維生素B7會造成什麼危害？



缺乏維生素B7（生物素）可能導致多種健康問題，主要包括：

1.皮膚問題：可能出現乾燥、皮疹、皮膚炎症，特別是在面部和身體其他脂脂肪分泌較多的區域。

2. 頭髮問題：生物素缺乏可能導致頭髮稀疏、脫落，甚至於嚴重脫髮。

3. 指甲問題：指甲變薄、脆弱，容易斷裂。

4. 神經系統問題：可能會出現神經痛、肌肉疼痛、抽搐和其他神經系統問題。

5. 精神健康問題：例如抑鬱、注意力不集中、嗜睡或幻覺。

6. 消化系統問題：如食慾不振、噁心和腹瀉。

7. 免疫系統弱化：更容易感染和長時間病程。

維生素 B7有副作用嗎？

維生素B7（生物素）也是一種水溶性維生素，通常過量的生物素會透過尿液排出，所以很少會造成毒性或副作用。然而，儘管生物素過量的副作用報告很少，若攝取超過推薦量的高劑量生物素，理論上可能會影響某些醫學檢測的結果，例如甲狀腺功能檢測。因此，建議在醫生的指導下使用任何補充劑，並遵守每日推薦攝取量。
