Oral dosing of vitamins K1 and K2 in ovariectomized rats: Effects on bone loss and serum/bone levelsVitamin K (VK) exists in multiple forms that share common biochemical structures to support VK-dependent protein carboxylation. Vitamin K may benefit bone by carboxylating the bone protein, ...
Find out the difference between vitamins K1 and K2, and discover why maintaining healthy vitamin K levels promotes skeletal and cardiovascular health.
The different chemical structures of vitamins K1 and K2 affect their bioavailability and metabolism, with K2 having a longer half-life in the circulation. A study comparing K1 and K2 in humans found that the two were similarly absorbed, however K2 (as menaquinone-7, MK-7) had higher ...
Circulating levels of vitamins K1 and K2 decreased in elderly women with hip fracture We measured the serum levels of phylloquinone (vitamin K1) and of the menaquinones, MK-7 and MK-8, in a group of 51 women with a mean age of 81 years who w... SJ Hodges,K Akesson,P Vergnaud,.....
Summary Associations between bone mineral density (BMD) and dietary vitamins K1 and K2 in 4,461 individuals were studied. For women, odds ratio of low BMD was 1.48 in lowest to highest quartile of K1. A weak positive association was found for K2. Our results do not support dietary vitamins...
