NOW 維生素 B-6 - 100mg 100 Caps
[3000456]
$6.99 $3.84


維生素B6是一種共同酵素Coenzyme,在細胞中參與多種蛋白質和氨基酸的代謝功能,可將色氨酸轉化為煙酸,參與脂肪代謝,可降低血中膽固醇的含量。 維生素B6可溶於水,為水溶性且對熱和酸穩定,它在鹼性環境中會被破壞,同時對光敏感。新鮮蔬菜含有維生素B6。

一項新的研究發現,維生素B6可降低結腸癌的危險。研究人員對32000多名年齡為30至55歲的婦女進行了研究,結果顯示,血液中維生素B6含量最高的女性,其患結腸直腸癌的危險比含量最低的女性 低44%。婦女的雌激素和皮質激素代謝也需要維生素B6。有的婦女在妊娠期會出現手足浮腫、指關節疼痛。絕經期的婦女和常服避孕藥的婦女會發生憂鬱 症,有悲觀情緒,脾氣急躁,缺乏性要求,自感乏力等。還有些婦女患有經前期緊張綜合征,表現為月經前眼瞼、手足浮腫,失眠、健忘。服用維生素B6後症狀可緩解或消失。

維生素B6缺乏時,成人表現為眼睛、鼻子和嘴周圍的皮膚上出現油脂,鱗屑即脂溢性皮炎,隨後向身體的其它部分蔓延;舌紅光滑;體重下降;肌肉無力;急燥,精神抑鬱。 嬰兒表現為神經急燥,肌肉抽搐和驚厥。

維生素B6相對無毒,但是大劑量可引起嗜眠,成癖的副作用。孕婦如果長期過多服用維生素B6,致使胎兒產生依賴性。而一旦離開母體後缺乏維生素B6, 維生素B6的來源不像在母體裡那樣充分,內中樞神經系統的抑制性物質含量降低,結果出現一系列異常表現。常見的異常表現有容易興奮、哭鬧不安,容易受驚, 眼球震顫,反復驚厥,有的小兒在出生後幾小時或幾天內就出現驚厥。在1~6個月齡時還會出現體重不增。如果診治不及時,將會留有智力低下的後遺症。 這是由於維生素B6與氨基酸的吸收、蛋白質的合成,以及神經、脂肪的代謝有密切關系,是細胞生長發育所必需的物質。但因其在食物中廣泛存 在,生理需要量很少,故缺乏症在成人中很少發生。而小兒一日有1~2毫克即夠。
