The European Journal of Clinical Nutrition recently published a study that adds to the growing body of evidence showing that vitamin K2 as MenaQ7 can be delivered and is highly bioavailable through yoghurt and softgel capsules, making the nutrient safe, effective and available to an even larger population.
The researchers previously studied the effects of vitamin K status after 8 weeks of intake of a yoghurt fortified with MenaQ7 PURE and enriched with vitamins C and D3, magnesium and polyunsaturated fatty acids. For this new study, the researchers compared the fasting plasma concentrations of MK-7 from (a) yoghurt enriched with MK-7, vitamins D3 and C, magnesium, n-3 poly unsaturated fatty acids (n-3 PUFA) and fish oil (yoghurt Kplus); (b) yoghurt fortified with MK-7 only (yoghurt K); and (c) softgel capsules containing only MK-7 for 42 days in healthy men and postmenopausal women between 45 and 65 years of age.
The MK-7 in the yoghurts and the capsules was MenaQ7 from NattoPharma ASA. Circulating MK-7, 25-hydroxy vitamin D (25
The increase in plasma MK-7 with the yoghurt Kplus product was more pronounced than the increase in MK-7 with the capsules. However, circulating dp-ucMGP and ucOC were significantly lowered after consumption of both the yoghurt products and the MK-7 capsules, reflecting vitamin K status improvement from both delivery methods.
“This important study validates obtaining vitamin K2 from food sources is essentially equivalent to vitamin K2 delivered in supplements,” says Hogne Vik, Chief Medical Officer with NattoPharma, exclusive global supplier of MenaQ7. “Clearly, getting vitamin K2 from diet is ideal, be it cheese, natto or enriched yoghurts. However, as most Western populations are deficient in this essential nutrient, they are not getting enough from diet, making supplementation a viable alternative.”
“This study further affirms that MenaQ7 is a safe and effective as either a supplement or a functional food,” adds Vik. “We see this as support to further explore the use of MenaQ7 in yogurt and other dairy products so we can reach an even wider audience.”
