5 Responses to “what is the side effect of excessive vitamin E intake?”
A very interesting article in the Journal of Biological Psychology, Vol. 43, 969–972, reported that taking high doses of Vitamin E, or Alpha-Tocopherol (1,600 IU/day), decreased—by 40%—shaking that was caused by medicines used to treat schizophrenia. Another group on schizophrenia medication—but that took a placebo instead of Vitamin E—worsened by 20%, as would be expected without treatment. This is a remarkable result because no adequate treatment for this condition currently exists and no new treatments have been attempted in quite some time. What is especially exciting is the fact that this is a vitamin, which is relatively safe. Even in doses as high as 1,600 IU, few studies show that Vitamin E intake has any toxic side effects.
Vitamin E is also used as an antioxidant therapy for many other conditions—specifically, to prevent heart disease, possibly cancers, and damage from toxic agents both internally and externally. In addition, Vitamin E has a very potent ability to convert damaging LDL (low density lipoprotein), or bad cholesterol, to “not so bad” cholesterol.
The shaking, called Tardive Dyskinesia, is relatively common—not unlike that associated with Parkinson’s disease. Whether Vitamin E has any utility in the treatment of other shaking neurological conditions is yet to be seen or even tested. Vitamin E is a fat-soluble vitamin, with a very high rate of absorption into the central nervous system, and is composed of a large amount of fat tissue.
Be very cautious when taking doses any higher than 1,600 IU daily, as toxic damage from Vitamin E has been reported in a few cases. Vitamin E is made from plant products—specifically, soy-based products. While it occurs naturally in many foods, most people take doses that could not possibly be consumed in a normal diet. Therefore, the dose is customarily taken in vitamin supplements and has little relationship to Vitamin E’s natural function in the body.
Any food product can act like a drug when people consume large quantities of concentrated supplemental agents. Like any drug, excessive amounts may be toxic. The effects, and the side effects, might not be as predicted from the same food consumed in normal amounts and with normal preparation. Therefore, do as much research and study as possible before you take any vitamin pills or other agents.
The Food and Nutrition Board of the Institute of Medicine has set an upper tolerable intake level (UL) for vitamin E at 1,000 mg (1,500 IU) for any form of supplementary alpha-tocopherol per day. Based for the most part on the result of animal studies, the Board decided that because vitamin E can act as an anticoagulant and may increase the risk of bleeding problems this UL is the highest dose unlikely to result in bleeding problems.

I saw a story recently on either CBS, or ABC that said taking too much vitamin E could cause an early death. And they don’t know why.
You should talk to your doctor.
