A Vitamin D Council newsletter prints a mother's letter: her five-and-a-half-week-old daughter's unexplained arm fracture, and later micro-fractures, led two hospitals to suspect child abuse. The baby's vitamin D was low-normal, the mother's was never tested, and neither took a full history.

Could This be the Key Factor Spiking the Rise in Dementia and Alzheimer's?
In a two-year trial of 168 volunteers with mild cognitive impairment, brains of those taking high-dose folic acid, B6 and B12 shrank 0.76 percent a year against 1.08 percent on placebo. Mercola notes about half of people diagnosed with MCI go on to develop Alzheimer's within five years.

Pregnant? Why You Need to DEMAND This Test ...
Mercola cites research finding generally low vitamin D among 50 women with early-onset severe preeclampsia, averaging 18 nanograms per milliliter. An editor's note urges pregnant women to have their levels checked and to get safe sun exposure.

B vitamins may help prevent cancer
In Cancer Epidemiology, Biomarkers & Prevention, the highest serum vitamin B2 and B6 levels were tied to 29 and 32 percent lower colorectal cancer risk, with no effect from B12. A separate EPIC analysis linked B6, methionine and folate to lower lung cancer risk.

B vitamins linked to lower risk of depression
A Psychosomatic Medicine study from the University of Tokyo found folate and vitamin B6 intake inversely associated with depressive symptoms in early adolescence, with reductions of up to 40 and 28 percent. Riboflavin helped girls only; B12 showed no link.

B vitamins prevent dementia
In an Oxford trial, 168 volunteers with mild cognitive impairment took high-dose B12, folate and B6 for two years; brain shrinkage averaged 0.76 percent a year against 1.08 percent on placebo. Researchers did not test cognition, and a Dutch trial using lower doses found no benefit.

Could This Simple Habit Actually Reduce Cancer and Diabetes by 50%?
Reuters reports that vitamin D influences more than 200 genes, among them genes tied to cancer and multiple sclerosis, acting through receptors that bind specific spots on the genome. Mercola cites over 800 cancer studies and claims optimal levels can halve the risk of several cancers.

Who Knew this Vitamin Could Prevent Mold Allergies?
A Journal of Clinical Investigation study reported that stronger Th2 reactivity to Aspergillus fumigatus, a common household mould, went with lower average blood vitamin D, leading researchers to suggest vitamin D may help treat or prevent allergy to it.

Vitamin D Linked To Cancer and Autoimmune Disease Genes
Reuters reports on Genome Research findings that vitamin D influences more than 200 genes, including ones tied to cancer and autoimmune disease, acting through receptors that bind specific spots on the genome. Mercola argues other work puts the count closer to 3,000.

In memory of one of the greatest contributors to human understanding of vitamin D...
An obituary for vitamin D researcher Dr. Frank C. Garland, who with his brother Cedric first linked vitamin D deficiency to cancer in a 1980 paper and won the Arnold-Rikli Prize. Evidence now covers as many as 20 vitamin D-responsive cancers.

Vitamin A increases the presence of the HIV virus in breast milk (PR)
Two studies by University of Michigan epidemiologist Eduardo Villamor suggest vitamin A and beta-carotene supplements raise HIV levels in breast milk, possibly by increasing subclinical mastitis. He says the supplements do not look like a safe intervention for HIV-positive women.

This Could Be Even BIGGER than the Vitamin D Discovery…
Researcher Cees Vermeer argues most people get enough vitamin K to clot blood but not enough for its other benefits, and that blood tests mainly reflect yesterday's diet. K1, from green vegetables, supports clotting and helps keep blood vessels from calcifying.

Ketamine fights depression, so does vitamin D
Yale researchers mapped ketamine's action in the rat prefrontal cortex and found it works through a pathway requiring mTOR that quickly forms new synaptic connections, which may explain why it lifts depression within hours. The drug must still be given intravenously and can cause psychotic symptoms.

Important Vitamin Deficiency Linked to Arterial Stiffness
In a trial of 44 black teenagers, 2,000 IU of vitamin D a day reduced central arterial stiffness and on average brought participants to sufficiency, while the 400 IU dose recommended by the American Academy of Pediatrics did not.

B Vitamins and the Aging Brain Examined
In the Sacramento Area Latino Study on Aging, which enrolled nearly 1,800 Hispanic seniors, blood analysis tied lower folate to dementia symptoms and cognitive decline even though under 1 percent were deficient. Among women only, the lowest third for folate had twice the depression symptoms.

Additional Opportunities to Prevent Neural Tube Defects with Folic Acid Fortification
A CDC Grand Rounds report notes U.S. pregnancies affected by neural tube defects fell from about 4,000 in 1995-96 to 3,000 in 1999-2000 after folic acid fortification was mandated, and that adequate periconceptional folic acid can prevent 50 to 70 percent of cases.

The Vitamin D Newsletter: Gary Null and Vitamin D Toxicity
The Vitamin D Council newsletter recounts Gary Null falling ill after a batch of his own supplement apparently held 2,000,000 IU of vitamin D3 per serving instead of 2,000 IU, and revisits 1930s reports of massive doses. The author warns readers not to try such doses.

Dementia patients can use high doses of vitamin E safely
Baylor researchers followed 849 Alzheimer's patients told to take 1,000 IU of vitamin E twice a day between 1990 and 2004. Those using vitamin E, with or without a cholinesterase inhibitor, were 23 percent less likely to die; those on the inhibitor alone faced 20 percent higher risk.
