Swanson Ultra Natural Vitamin K2 (Menaquinone-7 from Natto) is the most biologically active form of vitamin K2. Everyone knows about calcium and vitamin D for bone health, but what about vitamin K2? If there's one vitamin you should know more about, this one's it. While vitamin K1 is mostly involved in blood clotting,
Vitamin K2 may not be a headline grabbing nutrient or antioxidant like vitamins C or A but there can be no doubting its importance to your ongoing health. Traditionally sourced from leafy green vegetable like spinach, it is vital to keeping your body's skeletal infrastructure in good shape, not to mention the role it plays in keeping your heart healthy.
Unfortunately, like so many other vital nutrients, it also suffers from low rates of bioavailability when ingested through natural food sources. It transpires that our bodies just aren't capable of aping the necessary phytochemical absorption rates that other animals display when it comes to getting all the goodness out of vitamin K2.
That's why Swanson have turned to an age old source in the hope that they might better create a more amenable and body-compliant form of K2. That source is the Soybean. More specifically - Natto, a form of fermented soybean which is rich in a chemical called menaquinone-7.
Scientifically proven to help promote superior cardiovascular and bone strength, menaquinone-7 works by preventing calcium from settling in the arteries instead of reaching the bones where it is needed.
Because Vitamin K2 is made up of 13 different numbered menaquinones, it made sense to try to understand just which of them actively promote the absorption of this essential nutrient into those organs that need it the most.
Following extensive research completed in the Netherlands, there is now significant evidence that the Natto derived form of menaquinone-7 is the superior solution to optimal absorption.
A 2004 study was commissioned into the effects of proper vitamin K2 consumption by the ‘Journal of Nutrition'. In an attempt to better understand the health benefits of the nutrient, they uncovered some revealing facts.
By coagulating the blood, Swanson Ultra Natural Vitamin K2 actually helps to direct our body's calcium deposits. So much so that without a proper supply of K2, we could effectively be wasting our calcium supplies. A situation which could lead us into a range of deficiencies and diseases such as osteoporosis or coronary heart disease.
