Modest supplementation with vitamin K2 menaquinone-7 supports healthy bone growth and development in children by increasing activation of the bone-building protein osteocalcin, according to a study recently published in British Journal of Nutrition.

This randomized, double-blind, placebo-controlled study examined the effect of 45 mcg natural vitamin K2 as menaquinone-7 (MK-7) (MenaQ7, from NattoPharma and PL Thomas) on the circulating levels of osteocalcin. Results showed that 8 weeks of MenaQ7 supplementation in healthy prepubertal children increased blood levels of vitamin K2 as MK-7 and significantly increased the amount of active osteocalcin.
