2012年8月21日 更新者:Maastricht University Medical Center
The Effects of a Vitamin K-enriched Dairy Product on Vitamin K-status
In this study, the beneficial effect of a nutrient enriched dairy product will be investigated on vitamin K-status.
To achive this benefit, the study product contains extra vitamin K2.
In addition, extra dairy minerals have been added to the study product that may support general health.
研究概览
详细说明
In earlier studies, cardiovascular disease and osteoporosis were found to be associated with K2 intake, notably the higher menaquinones, MK-7, MK-8 and MK-9.
Of these higher menaquinones, MK-7 was suggested to be the most effective form with respect to intestinal absorption, biologic half-life time, and efficacy on circulating biochemical markers.
MK-7 is a natural product that is found in cheese, curd, and the Japanese food natto.
Therefore, a nutrient enriched dairy product has been developed containing MK-7.
The efficacy of this new product will be investigated on vitamin K status and on general health markers.
