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.
