We're thrilled to roll out Vitamin K2 MK-7 today. Vitamin K is not as well known as many of its other letter-vitamin siblings, but it plays an essential role in bone health, blood clotting and — as emerging research shows — healthy arteries.
The vitamin K family breaks down into a few variations. K1 is found in leafy green vegetables and mainly plays a role in blood coagulation, or ensuring that you stop bleeding from cuts and scrapes.
Gut bacteria can convert K1 into K2, which we believe is worth supplementing as it is very difficult to obtain through diet alone. Vitamin K2 is divided into various forms denoted by 'MK', such as 'MK-4' and 'MK-7'. MK-7 is the form we chose as it has a longer half-life and is better absorbed.
The only prominent sources of vitamin K2 are in fermented foods such as natto, a pungent soybean dish from Japan — definitely an acquired taste. It's also present in unreliable amounts in some animal products such as cheese, but the exact amounts are highly dependent on how much and which bacteria are used.
Science is still emerging about the role of Vitamin K2 MK-7, but promising studies have shown that the compound can help support healthy bones and springy, elastic arteries.
It works synergistically with vitamin D and minerals such as magnesium and calcium. Vitamin K supplementation is associated with an increase in bone density and a decrease in bone fractures.
Vitamin K can also reduce hardening of the arteries by preventing excess calcium deposits from accumulating. Stiff arteries contribute to atherosclerosis, or a buildup of plaque and other substances in the artery walls, which is a predictor for cardiovascular disease.
Researchers are still working on the effects of vitamin K and the daily maximum amounts, so just to play it safe, we put a 45 mcg dose into each softgel. The current RDAs are 120 mcg for men and 90 mcg for women. We added extra virgin olive oil for additional health benefits and to help with absorption.
Since it's a fat-soluble vitamin, we take ours with a meal or with a dose of Ultra EPA+DHA or other omega-3 fatty acids. We also like taking it with Daily D3 as vitamin K and vitamin D work synergistically together.
