Vitamin K1 Associated With Reduction in Hip Fractures
As we age our bones become less dense, increasing the risk of hip fractures. A recent study from University of Bergen in Bergen, Norway, suggests that increasing your intake of vitamin K1 may help reduce the risk of hip fracture.
The study was published in the August, 2011 edition of the journal Bone.
The researchers examined 1569 men and 1238 women between the ages of 71 and 75 who participated in the Hordaland Health Study. Information about K1 and K2 levels was taken when people were hospitalized in Western Norway and hip fractures were reported by the hospitals.
They found that those in the lowest quartile of vitamin K1 intake had a 57% higher chance of suffering from a hip fracture than those in the highest quartile of vitamin K1 intake. They also found that K2 levels were not associated with hip fractures.
Low levels of vitamin K1 have previously been linked to a high risk of osteoporotic fracture, vascular calcification and cardiovascular disease. The Food and Nutrition Board of the Institute of Medicine suggests that an adult 19 years of age or older should receive 120 mcg of vitamin k per day.
Vitamin K1 can be found in leafy green vegetables and some oils but it has a very short half-life, meaning it loses half of its potency in 1-2 hours. As a result, increasing your K1 intake through diet alone can be very difficult. If you are concerned about bone density, consider taking a daily supplement of vitamin K.
