The value of vitamin K2

The value of vitamin K2
Vitamin K may well just be one of those vitamins you don’t give much thought to, and while it may not be top of mind, its importance for supporting some key areas of health including both bone and cardiovascular health can’t be understated. We explore the value of vitamin K2.

What is vitamin K?

Vitamin K is a group of structurally similar, fat-soluble vitamins that occurs naturally in two forms – phylloquinone (vitamin K1) and menaquinone (vitamin K2) - both of which have different actions in the body.

What’s the difference between vitamin K1 and vitamin K2?

Vitamin K1 is well-known for its role in blood coagulation, while emerging evidence supports vitamin K2 for both bone and cardiovascular health.

How does vitamin K2 work?

Vitamin K2 supports bone mineral density and bone strength by activating osteocalcin, an important marker of bone mineralisation, that binds to hydroxyapatite to facilitate the deposition of calcium into bones, helping to support bone mineralisation.

Why 180 micrograms?

It has been shown the beneficial effects on both bone and cardiovascular health with vitamin K2 occur at this relatively low dose of 180 micrograms/day[1].

Vitamin K2 for post-menopausal women

Vitamin K2 is a key nutrient for post-menopausal women. Menopause, generally occurring between the ages of 45 and 55, causes a drop in oestrogen levels, resulting in increased bone loss. It is estimated that women lose up to 10 percent of their bone mass in the first 5 years after menopause[2]. Vitamin K2 can help maintain bone mass in postmenopausal women. A 3-year, randomised, double-blind, placebo-controlled study found that 180 micrograms of vitamin K2 supported bone integrity in postmenopausal women[3].

Vitamin K2 for cardiovascular health

Vitamin K2 also supports cardiovascular health and blood vessel health, particularly artery health. The benefits on cardiovascular health are brought about through regulation of calcium homoeostasis. In a 3-year, randomised, double-blind, placebo-controlled intervention trial, 180 micrograms of vitamin K2 maintained cardiovascular and arterial health in postmenopausal women[4].
