維他命E是什麼?

   維他命E就是Tocoperol,它廣泛分佈於植物中,
   其有四種同族體,即α,β,γ,δ形態。

   在小麥胚芽中以α-,β-Tocoperol較多,
   大豆中以γ-,δ-Tocoperol較多,
   而玉米中則以γ-Tocoperol較多,
   在生理效果而言以α-Tocoperol較佳。
   天然界存在者為d(右旋)體,合成品則為dl(混旋)體。

維他命E一直因它的抗氧化性而受到讚揚,而且在防止心臟病方面也逐漸受到重視。經研究,維他命E似乎可以降低發生心臟病的風險達三分之一,而且也可以提昇乙型胡蘿蔔素(β-carotene)的防衛心臟效果。

維他命E就如同阿斯匹靈一樣,可以利用促進防止血液凝結的因子來幫助維持血液暢通。在酵素反應裏,作為一種輔因子(cofactor),對造血機能和血紅素的形成扮演保護紅血球細胞免於溶血。也有研究發現維他命E也有助於製造抗體,增加T細胞的活性,對於免疫功能低下的老年人特別重要。

維他命E往往被使用作為維持正常生殖機能,防止習慣性流產、早產、更年期障礙,睪丸機能退化等,並能促進末稍循環、強化血管壁、提高氧的利用效率,賦活內分泌系統。外用塗抹則可控制乾燥或龜裂的皮膚,及暫時減輕輕度的皮膚障礙如搔癢、陽光燒灼感,減少皮膚磨損等。

因維他命E能增強抗凝血劑的功效,所以當你正在服用抗凝血劑時,必須留意維他E可能會造成出血的災難。除此之外維他命E也會降低口服鐵劑的功效。因此服用維他命E時,應避免與抗凝血劑、鐵劑同時服用。而口服時有胃部不適感、腹瀉、便秘、發疹、肌肉無力等症狀,則為其偶見的副作用。  ( 以上資料來源: KingNet 國家網路醫院 /臺北市立中興醫院藥劑科主任 游秉源 )

若貓咪飲食中含有大量的不飽和脂肪酸(如菜油,鮪魚,肝臟,三文魚油等等)維他命E的需求也會提高,否則貓咪有機會患上痛苦的黃脂病

雖說維他命E的好處不少,但它屬於脂溶性,攝取過多反而會造成正常凝血功能或是阻礙其它脂溶性維他命的吸收。如作一般保健用途,可一星期一次餵貓咪吃400I.U.的維他命E即可。(以上資料來源: 貓咪飲食祕笈 / 蘇菁菁 )

天然維他命E的吸收效果優於人工合成的維他命E, 以下推薦2種在iHerb上暢銷的天然維他命E, 皆通過GMP認證, 人貓可食.

 

 

Description

  • Antioxidant Protection
  • Mixed Tocopherols & Tocotrienols
  • GMP Quality Assured
  • A Dietary Supplement

Emerging research demonstrates that gamma-Tocopherol, the most abundant form of Vitamin E in the diet, has very important and unique functions. Central to these functions is its capacity to detoxify reactive nitrogen species, an especially destructive form of free radical. In addition, gamma-Tocopherol acts to trap and remove free radicals from the body in a way that alpha-Tocopherol cannot. NOW® Advanced Gamma E Complex provides the necessary full range of antioxidant protection because it contains a more natural balance of Tocopherols plus a full complement of Tocotrienols. NOW’®s “Advanced” formula thereby provides superior support for cardiovascular health, as well as protection for the health of the prostate and the colon.

Suggested Use

As a dietary supplement, take 2 softgels 1 to 2 times daily, preferably with meals. Consider taking this product in combination with NOW CoQ10 and Omega-3 Fish or Flax Seed Oil.

  • 請問
    為什麼"勿和魚油同時使用"@@?
  • 因為維他命E有加強抗凝血的作用,而魚油的作用也是抗凝血(CoQ10也是),考慮同時使用會使抗凝血的功能加乘,所以在產品的使用建議上有寫: Consider taking this product in combination with NOW CoQ10 and Omega-3 Fish or Flax Seed Oil.

    另外,如果是人食用,也不建議和鐵劑同時服用,兩者最好間隔30分鐘以上.

  • 我本來想說補充魚油也需要補充E,
    E又可以抗氧化,乾脆二個混在一起餵,
    原來兩個都有抗擬血功能,不適合一起餵.

    感謝格主^^
  • 分開餵就好啦!
    養貓真的長很多見識哩 ^^

  • 格主:您好
    因為找尋資料而發現您這用心又無私的提供資料的部落格,看完您此篇的文章後有些疑問想要請教格主就是有關建議使用中所提到的Consider taking this product in combination with NOW CoQ10 and Omega-3 Fish or Flax Seed Oil.
    以此段意思所譯,不是建議維他命E與Omega-3及Q10一起服用嗎?因就我所知以人類而言此三類者是一起服用較好,但格主所言之意也有所道理及其考量之處,若依格主所建議分開食用的話,請問是指先吃一種後隔30分鐘以上再吃另外一種還是今日先吃一種明日再吃一種的方式呢?
    若有冒犯之處還請見諒,謝謝您
  • 人類而言此三類者是一起服用較好 <---要間隔服用, 以免造成凝血障礙, 請諮詢您的醫院營養師.
