High-dose vitamin regime may help slow Alzheimer's

March, 2003

A preliminary study suggests that a regime of high doses of folic acid, B12 and B6 reduces levels of homocysteine in people with mild to moderate Alzheimer’s. A larger study, recruiting 400 participants from all over the U.S., is to be undertaken to assess whether such a vitamin regime can slow the progression of Alzheimer's disease. In the meantime, it is not advised that people take high doses of these vitamins, as there are possible side-effects, including peripheral nerve damage.
