Q. Dear Terry, “I am taking an excellent pain formula you recommended in one of your past articles that contains curcumin with high absorption, boswellia, DLPA and nattokinase. I am also taking a bone product with vitamin K from natto. Am I getting too much vitamin K if I combine these products? PS—the pain formula is working GREAT!” – Bonnie F., Houston, TX A. Dear Bonnie, I am so glad the pain formula is giving you such great results. And I am also so very glad you asked this question, because there is a lot of confusion out there about natto, nattokinase, and natto K-2, or menaquinone. Natto is a food in Japan that is made from fermented soybeans. It is extremely healthy and full of a wide variety of nutrients. In fact, two compounds found in natto are so healthy that they are extracted and also sold as dietary supplements: nattokinase, an enzyme, and natto K-2, a bone and heart healthy form of vitamin K that promotes calcium absorption and guides it into the bone. However, even though BOTH of these are found in natto, they are not at all alike. Natto K-2 is used in formulas targeting bone and heart health as a unique form of Vitamin K, an essential nutrient. Nattokinase, on the other hand, is an enzyme that promotes healthy circulation and balances levels of fibrinogen in the body. Therefore, the nattokinase in the pain product does NOT contain any vitamin K, any more than natto K-2 contains any circulation-enhancing enzymes! The best analogy I can think of is the orange. An orange is a food. You can also extract vitamin C from an orange, and you can extract fiber from an orange. The resulting vitamin C would not have any fiber, and the fiber would not have any vitamin C, even though both are from the same orange. I hope this helps answer your question! Healthy regards!
