Q: What makes K2 Clear unique?
A: The combination of Nattokinase and the new and unique form of vitamin K2 known as menaquinone-7 in one supplement makes K2 Clear a one-of-a-kind product for cardiovascular and bone health.
Q: Who should take K2 Clear?
A: Anyone who wants the bone building power of vitamin K2 along with the cardiovascular support of nattokinase and vitamin K should consider K2 Clear.
Q: What is unique about Bone Vitals?
A: Bone Vitals is a one-of-a kind bone health formulation that is designed to encourage the natural bone building process. It contains menaquinone-7, the long-chain form of vitamin K2 that has been shown to promote the growth of new bone, protect against bone loss, and reduce the risk of bone fracture.
Q: How come there isn't any calcium in Bone Vitals?
A: Despite what you may have heard, calcium alone is not the answer to bone health. Because of the widespread practice of fortifying foods and beverages with calcium, most people are already consuming plenty of calcium in their daily diet. Bone Vitals is designed to assist your body in properly processing and recycling the calcium you are already consuming. Bone Vitals contains the nutrients and minerals that work with calcium to build strong, new bones. However, if you do require calcium supplementation, please see Bone Vitals + Calcium.
Q: I've seen vitamin K2 sold in milligram amounts, how come the vitamin K2 in Bone Vitals and K2 Clear is in microgram amounts?
A: Vitamin K2 (menaquinone) is commercially available in two forms, MK-4 and MK-7, which differ in clinically significant ways. MK-4, a short-chain menaquinone, is available as a synthetic compound (menatetrenone), while MK-7, a long chain menaquinone, is a natural menaquinone derived from natto fermentation.
One should be cautious about consuming MK-4, the synthetic form, of vitamin K2. Though it will appear quickly in the blood, it has a half-life of only 1-2 hours. For this reason, high pharmacological doses (typically 45 mg/day divided into multiple doses) are necessary to achieve bone health benefits. However, such frequent doses are problematic for patient compliance and the large dosage provide unnaturally high peaks of the vitamin While long term dietary studies show 45mcg of K2 as MK-7 is safe and effective for providing many health benefits, no such studies exist for taking 1,000 times this amount as the synthetic MK-4
On the other hand, the MK-7 form of vitamin K2 is not only highly bioavailable and bioactive—a mere 45 mcg/day was sufficient to activate osteocalcin in the Rotterdam study—but has a much longer half life of 3 days, which enables the body to build up a buffer that can supply vitamin K2 to all tissues 24 hours a day. At 45 mcg/day (a dose 1,000 times less than that needed for MK-4), natto-derived MK-7 is easier for to use and less likely to interact negatively with blood-thinning medications.
Q: Why are the percent daily values percentages for vitamin K1 and K2 different on the supplement facts panel?
A: The government has set the daily value (the estimated daily need) for vitamin K at 80 mcg based on blood coagulation studies. At the time this was established, the different types and individual functions of vitamin K's could not taken into consideration, because little was known outside of vitamin K's coagulation function. Current science indicates K2 is more bioavailable and functional at less than the RDA, while K1 is needed at higher than RDA levels for optimal bone health.
