Saturday October 11, 2008 (foodconsumer.org) -- A new
study published online ahead of print in the journal Diabetes Care suggests
that taking vitamin K1 supplements may help reduce risk of diabetes in older
men.
The study led by Sarah Booth from the Jean Mayer USDA
Human Nutrition Research Center at Tufts University and colleagues
showed those who took vitamin k1 supplements
reduced their risk of developing insulin resistance.
Insulin resistance is the condition in which normal
amounts of insulin are produced but insulin does not respond adequately from
fat, muscle and liver cells.
For the study researchers followed 355 non-diabetic men
and women ages 60 to 80 with 60 percent women.
Participants were given vitamin k1 supplement at a dose of 500
micrograms per day of phylloquinone or placebo for 36 months.
Among men, but not women, those who took vitamin k1
supplement experienced a significant reduction in insulin resistance compared
to the placebo group.
