Vitamin K2 is Under-Appreciated

“If there’s a single vitamin you need to know more about, it’s vitamin K2. The first reason is you’re probably not getting enough. The second is that it doesn’t get the attention it deserves…” — Chris Masterjohn PhD.

For years many people have been taking high doses of vitamin D3 to promote calcium absorption to prevent osteoporosis. AND THEN THEY OFTEN GO ON TO DEVELOP OSTEOPOROSIS (and/or calcified plaque).

WHY? Because vitamin D3 moves the calcium from the gut into the blood, but it’s job has nothing to do with getting calcium from the blood into the bones. For that, vitamin K2 is needed!!!

There are two form of K2 – mk4 and mk7. Both are important. Mk7 has a half life in the body of 3-4 days, while mk4 has a half life of only a few hours. Mk7 (like K1) promotes blood clotting and mk4 does not. Both types clear calcium out of tissues and artery walls, but mk4 is better at it.

For healthy people who are concerned only about health maintenance, it is a good idea to supplement K2 in moderate amounts since it is difficult to obtain enough from food. Two excellent products for this purpose are:
1) Life Extension Super K
2) Innovix Labs Full Spectrum Vitamin K2


For treating atherosclerosis (plaque) OR osteoporosis, mk4 should be used in very large amounts (it’s non-toxic) such as 30-45 MILLIGRAMS per day divided into 3 doses. In addition, a moderate amount of mk7 (100-200 MICROGRAMS) can be added daily. When mk7 is used even in this lesser amount, it’s a good idea to supplement with nattokinase or serrapeptase to ensure no excessive blood clotting. These substances may also help to dissolve existing plaque as a plus.

Vitamins D3, K2, and A all work together synergistically. All should be supplemented together whether for normal maintenance or to treat disease conditions. (For vitamin A use retinol or retinyl palmitate, not beta carotene.)

Chris Masterjohn wrote a concise yet excellent article on K2.
