Effects of Dairy on Vitamin K-status

21. august 2012 opdateret af: 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.

Detaljeret beskrivelse

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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: nutrient enriched dairy
Yoghurt product which contains vitamin K2 and extra dairy nutrients; all in a concentration of 15% of the recommended allowed daily intake (RDI)
Kosttilskud: nutrient enriched product
The intervention in this study consists of the consumption of two nutrient enriched yoghurt products. The participants consume the study products twice a day during 12 weeks, one yoghurt product (250 ml) during breakfast and one yoghurt product (250 ml) during dinner.
Placebo komparator: Basic dairy
2 basic yoghurt products
Kosttilskud: basic dairy product
The intervention in this study consists of the consumption of two basic yoghurt products. The participants consume the basic yoghurt products twice a day during 12 weeks, one yoghurt product (250 ml) during breakfast and one yoghurt product (250 ml) during dinner.
