Caution

Most people get enough vitamin E from a balanced diet. So healthcare professionals don't often suggest that people take vitamin E supplements. If you've been diagnosed with mild to moderate Alzheimer's disease, some research suggests that vitamin E therapy might help slow the worsening of the disease.

But taking vitamin E by mouth might raise the risk of prostate cancer. Use of the supplement also may have other serious risks. This is mainly true at high doses and for people who have other health conditions or have had a heart attack or stroke.

Also, vitamin E acetate is used in some electronic cigarettes, also called e-cigarettes or vaping devices. Vitamin E acetate has been linked to lung injury in people who vape.

If you're thinking of taking a vitamin E supplement, talk with your main healthcare professional about whether it's right for you.
