Menaquinone in Children (MIC) is a world-first study, being conducted in Western Australia, assessing the effectiveness of a Vitamin K- K2-Mk7 liquid supplement, assessing Vitamin K status using three functional markers as Vitamin K dependent proteins, and determining dietary Vitamin K1 and K2 intake using a new Australian foods Vitamin K database. It is a double-blind randomised control trial for 1 month of Vitamin K versus placebo in 50 healthy children and adolescents aged 4 to 17 years old. The intervention dosing is at 1.5 micrograms per kilogram of bodyweight.

Interventions

Intervention is for 1 month taking daily liquid drops orally of Vitamin K2-Mk7 1.5 micrograms per kilogram of body weight in a home setting. At baseline completing an online food frequency questionnaire. At baseline and 1month- end of study, - providing two non-consecutive days 24 hour dietary intake information - collecting a faecal sample at home in an all in one kit - having a blood sample taken by a paediatric experienced phlebotomist for serum Mk7 and three functional Vitamin K status
