Vit K may reduce insulin resistance

Vitamin K is not just for bone health any longer.
According to research performed at Jean Mayer US Department of Agriculture, Human Nutrition Research Center, Tufts University, Boston, vitamin K supplementation shows hope for improving insulin resistance (for men at least). They supplemented nondiabetic men and women for 36 months. Their conclusion? Vitamin K supplementation for 36 months at doses attainable in the diet (500 mcg/day phylloquinone) may reduce progression of insulin resistance in older men. For some odd reason there were no statistically significant differences in outcome measures between intervention groups in women.

Another study out of UC San Diego states “Accumulating research suggests low-circulating vitamin D concentrations, i.e., 25-hydroxyvitamin-D [25(OH)D], may be associated with an increased prevalence of metabolic syndrome”. Perhaps vitamins D and K make a good pair.
