Vitamin E Helps Alzheimer's Patients

January 03, 2014
Favorited Not Favorited
A new study suggests that high-dose vitamin E can help people with Alzheimer's disease retain their ability to perform activities of daily living (such as dressing) for several months longer than those given placebo, reducing caregiver time. A similar dose of vitamin E has been shown in other studies to slow the progression of the disease in some people and to reduce the rate of conversion to Alzheimer's among people with mild cognitive impairment. For details -- including the dose and form of vitamin E used and our tests of supplements on the market which can provide this dose -- see the update to the Vitamin E Supplements Review >>

Latest Supplement Recommendations

November 16, 2013
Favorited Not Favorited
New draft recommendations on vitamin and mineral supplement use were published this week by the U.S. Preventive Services Task Force. The recommendations apply only to healthy adults without nutritional deficiencies. They focus only on the use of supplements for the prevention of cardiovascular disease and cancer at doses not exceeding tolerable upper intake levels. The recommendations are based on existing science and are generally consistent with information already presented in ConsumerLab.com's Product Reviews.  We have summarized the recommendations below, with links to more information in ConsumerLab.com's reports:

- Beta-Carotene and Vitamin E:  Supplementation with either does not provide a benefit. Vitamin E does not pose a risk of harm, but beta-carotene increases the risk of lung cancer in people at risk for lung cancer.

- Other Single Vitamins, Minerals, Pairs, and Multivitamins: There is inadequate evidence regarding a benefit or a risk of harm.

The task force stressed that at excessive doses (above tolerable upper intake levels) there is evidence of harm with supplementation, such as with vitamin A and vitamin D

Antioxidants: Too Much of a Good Thing?

August 24, 2013
Favorited Not Favorited
A new, long-term study of Americans found the risk of dying over the course of the study (about 14 years) was lowest when antioxidant levels in the blood were above the lowest levels (the bottom 20% of the population). However, for people in the top 20% of blood levels for vitamins A and E, the risk of death increased compared to people with moderate levels. For selenium and beta-carotene, there was no significant difference in the death rate between moderate and high levels, although for vitamin C some additional benefit was seen at high, but not the highest, levels.
 
The results suggest that antioxidant supplements may be useful for those who are nutritionally deficient, but, as noted by the researchers, "beyond a certain threshold, higher levels do not lead to additional benefit, and may potentially be toxic."
