Among 38,000 adults followed a decade, those eating the most vitamin K were about 20 percent less likely to be diagnosed with type 2 diabetes, with a stronger link for K2 from meat, cheese and eggs. Mercola suggests the vitamin lowers inflammation and improves insulin use.

High-Dose Vitamin C Therapy Proven Effective (PR)
The Orthomolecular Medicine News Service argues that 75 years of physician reports and studies on high-dose vitamin C have been ignored, and that unsuccessful research used doses far too low to show results. It traces the approach to Jungeblut, McCormick, Klenner, Riordan and Cathcart.

Vitamin C fights prostate cancer - study
Rats implanted with hormone-refractory prostate cancer cells and given pharmacological doses of vitamin C by injection for 30 days had significantly smaller primary tumours and far fewer lung and lymph node metastases, researchers report in In Vivo.

B-vitamins linked to lower risk of depression
Following 3,503 adults aged 65 or older for 12 years, researchers tied each extra 10 mg of vitamin B-6 and 10 micrograms of B-12 in total intake to 2% lower annual risk of depressive symptoms. Dietary intake alone showed no such association.

Vitamin C cuts smoking-induced atherosclerosis risk
Guinea pigs exposed to cigarette smoke developed atherosclerosis, but those fed a vitamin C-supplemented diet rarely did, a Journal of Atherosclerosis and Thrombosis study found. The authors credit vitamin C with blocking smoke-induced apoptosis and platelet activation.

Folic acid helps vascular function in female amenorrheic runners
Twenty female runners aged 18 to 25 took 10 mg of folic acid daily for four weeks; vascular function returned to normal in the amenorrheic group while controls stayed normal. Runners who under-eat can stop menstruating and see estrogen fall to postmenopausal levels.

The Hidden Link to Black-White Disparities in Bad Birth Outcomes
A review weighed evidence tying maternal vitamin D to preeclampsia, preterm birth, gestational diabetes and fetal growth restriction, and its authors called for research testing vitamin D as a causal factor in black-white disparities in birth outcomes.

Could This ‘Humble’ Vitamin Hinder Future Cancers?
In the EPIC study of over 24,000 people followed more than a decade, those with the highest vitamin K2 intake were 14% less likely to develop cancer and 28% less likely to die of it. Mayo Clinic work tied high vitamin K intake to 45% less non-Hodgkin lymphoma.

Vitamin B dangerous for diabetics with kidney disease
A JAMA study led by David Spence found diabetics with kidney disease taking folic acid, B6 and B12 had a steeper decline in kidney function and twice the rate of heart and stroke events, though homocysteine fell. The researchers say those on the regimen should stop.

Can we enlist vitamin D to fight flu pandemic?
The piece sets out John Cannell's hypothesis that flu is a symptom of vitamin D deficiency. It notes his argument that most of the 36 children the CDC reported dying of H1N1 in 2009 had neurodevelopmental conditions, stayed indoors and took anticonvulsants, all worsening vitamin D status.

Serum vitamin E may protect against Alzheimer's disease
Following 232 dementia-free adults aged 80 and over for six years, Karolinska researchers found those in the top tertile for total vitamin E had about 45 percent lower Alzheimer's risk, and for tocotrienols 54 percent. Among individual forms, only beta-tocopherol stood out.

In a study of 268 breast cancer cases and 457 controls presented at an AACR meeting, women taking multivitamins were 30 percent less likely and calcium users 40 percent less likely to have breast cancer, though calcium's apparent benefit vanished once DNA repair capacity was counted.
