Manaquinone-7 is Vitamin K2 (MK-7). Vitamin K1 is important for good blood clotting, but K2 has a wide range of other important functions, You’re going to hear a lot more about this remarkable vitamin. It is one of those nutrients, like omega-3 fatty acids and vitamins A, D and E, that are crucial for health but that have been stripped from our foods by the thoughtless industrialization of our food supply. Vitamin D moves calcium from the gut into the blood stream. Vitamin K2 moves calcium from the blood stream into tissues. Without it calcium can build up in places like the lining of the arteries, as calcium stones in the gallbladder and kidney, as bone spurs and calcification of the pineal gland. And then it is not available for building bone and for all the critical chemical processes which require calcium inside cells. If we have really good gut bacteria, we can make some K2. Mostly we get it from animals that are eating greens and fermenting them naturally in their gut. The only Vitamin K2 that I trust comes from microbiome labs.
