Among 3,258 Austrian patients followed 7.7 years, those with the lowest blood vitamin D levels were about twice as likely to die of any cause, including heart disease, as those with the highest. Nearly 23 percent of participants died, most from cardiovascular causes.

Mother's prenatal vitamin D levels affect baby's dental health
Among 206 pregnant Manitoba women, only 21 had adequate vitamin D in the second trimester. Of 135 infants examined, 21.6 percent had enamel defects and 33.6 percent had early childhood tooth decay, and their mothers had lower vitamin D levels during pregnancy.

Newborn vitamin A reduces infant mortality
Among 15,937 newborns in rural Bangladesh, a single 50,000 IU dose of vitamin A at birth was followed by a death rate of 3.85% versus 4.51% on placebo, a 15% reduction. Researchers say more studies are needed to see whether the benefit holds elsewhere.

Effective oral vitamin B12 soon available
Emisphere Technologies says its Eligen oral formulation raised vitamin B12 absorption to 7-30 percent, against roughly 1 percent for existing oral forms that leave doctors relying on shots. The animal results go to an AAPS conference; human studies are reportedly under way.

Sunshine vitamin may help prevent heart attack
Harvard researchers compared 454 men who had a heart attack or fatal heart disease with 900 who did not, and found men deficient in vitamin D faced 2.42 times the risk of those with sufficient levels. The authors caution that the sunlight pattern is not proof of cause.

Low vitamin D linked to high risk of leg artery disease
In a national survey of 4,839 US adults, 8.1% of those with the lowest vitamin D levels had peripheral artery disease versus 3.7% of those with the highest. The study was not a trial, so it cannot show that low vitamin D causes PAD or that supplements would help.
