Vitamin E is a term used to describe eight separate chemicals performing the same function.
Many physicians and nutritionists typically refer to alpha-tocopherol as if it were the only component of vitamin E, but, the fact is, it's just the easiest form of vitamin E to measure. Vitamin E consists of not just alpha-tocopherol but a total of four "tocopherols" and four "tocotrienols."
Vitamine
Can supplementing with vitamin E help if you have diabetes?
The sass seems to be "it depends."
A study conducted in Israel and published in late 2007 found that taking 400 Iu of vitamin E a day (and by "vitamin E," these researchers meant just alpha-tocopherol) could cut your risk of having a heart strike or stroke approximately in half if:
You have type 2 diabetes,
You're over 55 years old, and
You have a extra set of genes known as the Hp 2-2 genotype.
This means there are some habitancy whose arteries vitamin E can help a lot, and others maybe little or not at all.
In Western societies, only about 36 per cent of the habitancy has the Hp 2-2 genotype. (Scientists haven't measured the genotype in African and Asian populations yet.) The other 64 per cent won't benefit from taking alpha-tocopherol for their hearts.
Vitamin E, however, can have a much more direct succeed on diabetes when it's used in "pharmacologic" doses.
An Italian study found that taking 900 mg (that's about 1200 Iu) of alpha-tocopherol a day increased the quality of insulin to move glucose into muscle by about 30 per cent in type 2 diabetics. In this study, vitamin E performs good than any oral designate medication for type 2 diabetes on the market, but....
The qoute with taking a vitamin E supplement that's pure alpha-tocopherol at that dosage is that it can interfere with your body's absorption of the other forms of vitamin E (gamma-tocopherol in particular) and beyond doubt raise your risk of having a "sudden cardiovascular event."
You can avoid this qoute by taking a supplement that contains at least gamma-tocopherol in increasing to alpha-tocopherol, and preferably all eight of the chemical forms of vitamin E.
And if you have "just a touch of diabetes," that is, if you've been told you're "borderline diabetic" or if you have metabolic syndrome, consumption of all of the eight chemicals that make up "vitamin E" may be very useful to you.
A Finnish study found that high-level consumption of the four "tocopherols" and four "tocotrienols" that together function as vitamin E might sacrifice the risk of developing type 2 diabetes by about 30 per cent.
The Finnish scientists also found that high rates of consumption of a connected antioxidant, beta-cryptoxanthin, might sacrifice the risk of developing diabetes by about 40 per cent.
What's beta-cryptoxanthin?
Well, it's not vitamin E, but it has some of the same functions as vitamin E. Beta-cryptoxanthin is chemically similar to beta-carotene.
Beta-cryptoxanthin, like beta-carotene, is a provitamin that the human body can use to make vitamin A. This hard-to-pronounce antioxidant seems to keep Ldl cholesterol from changing into plaques and maybe to preclude the progression of arthritis.
And, for reasons scientists can't illustrate yet, it is connected with lower rates of diabetes. There's not known to be any downside to taking it. It tends to disappear from circulation in habitancy who use large amounts of margarines with plant sterols to lower cholesterol, like Benecol and Take Control.
So what's a diabetic to do?
Mixed tocopherols and tocotrienols ("natural" vitamin E) is probably more useful for most diabetics. 400 Iu a day is enough. 1200 Iu a day is better. Do not take more than 400 Iu a day of any supplement that's solely composed of alpha-tocopherol.
If you use Benecol or Take Control, be sure you get your beta-cryptoxanthan, whether from a supplement or from quarterly servings of avocado, cilantro, serrano peppers, or (in moderation) grapefruit, oranges, or watermelon.
