B vitamins for eye health

A heart disease study sponsored by the NIH has also yielded some interesting information about the relationship between B vitamins and eye health. The research study, from Brigham and Women’s Hospital in Boston, found that taking a mixture of B vitamins, including B-6, folic acid and B-12, lowered the chance of middle-aged women developing macular degeneration (a common form of vision loss in older adults) by one-third. The study, which tracked more than 5000 women age 40 and older, was published in the Archives of Internal Medicine, Feb. 23, 2009.

Note that NYBC stocks this B vitamin supplement:

B-right (Jarrow)

B-right includes folic acid, B-6 and B-12; one of the rationales for its formulation is to prevent buildup of the chemical homocysteine, which in studies has been associated with heart attacks.


Sublingual Vitamin B12 for better absorption

For those with serious Vitamin B12 deficiency, injections or sublingual tablets (tablets that dissolve under the tongue) are often recommended.

This recommendation may be especially pertinent for people with HIV who experience peripheral neuropathy. But B12 is crucial for many systems in the body, and the use of sublingual tablets may be advised in a number of cases.

Here’s a Canadian AIDS Treatment Information Exchange Info Sheet on Vitamin B deficiency in people with HIV; it presents some of the rationales for use, and also underlines the importance of getting an effective dose through injection or sublingual tabs: CATIE INFO SHEET ON HIV and VITAMIN B12

NYBC, like its predecesor DAAIR, stocks B-12 as Methylcobalamin (Jarrow). These are chewable tablets; or may be dissolved under the tongue. The methylcobalamin form is generally acknowledged to be well-absorbed (=”bioavailable”).
