In the 1930s Danish researchers noticed that baby chickens fed a fat-free diet developed bleeding problems. They eventually solved the problem with an alfalfa-based compound that they named vitamin K, for Koagulation.

Vitamin K is the umbrella term for a group of fat-soluble compounds comprising vitamin K1 and vitamin K2. Vitamin K1, also known as phylloquinone, is obtained in the diet from green leaves, broccoli, brussel sprouts and plant oils like rapeseed and olive oils, and makes up 90% of our K intake. Vitamin K2 (a family of menaquinones) is produced in smaller quantities by the friendly bacteria in the digestive tract.

Evidence from studies points to the importance of a regular intake of both vitamin K1 and K2 in order to achieve optimal calcium regulation. Research has confirmed their use in activating K dependant (VDK) proteins which are needed for blood coagulation and other important processes like bone metabolism, vascular health and the regulation of cell growth and apoptosis.

Many experts now believe that a sub-clinical vitamin K deficiency, that is, one that is not great enough to hinder blood clotting capacity, could be wide-spread and could contribute to osteoporosis, and other age-related diseases.

We should point out that supplementation of vitamin K in people under treatment with anticoagulants is contraindicated, and additional supplementation to than found in multinutrient formulas should be supervised by the health professional.
