Summary
Brief summary
Kidney disease is a major public health issue. The provision of dialysis has considerable economic impact; $150 million, 0.9% of the annual health budget is spent on treatment of End Stage Kidney Disease (ESKD) for <0.09% of the NZ population. There has been a steady growth in the number of patients with ESRD of 5-6% over the last 15 years. Cardiovascular disease is the major cause of mortality and a significant cause of morbidity in this group.

Menaquinone-7, a Vitamin K2 homologue is rare in the Western diet, has high potency, and a long half-life and may reduce cardiovascular disease.

We will trial if a novel health product enriched in Menaquinone-7, is tolerated in up to 30 patients with ESRD.

We will determine if the novel health product enriched in Menaquinone-7, will reverse markers of Vitamin K deficiency.
