I asked Healthy Origins executives directly what FORM their K2 mk7 provides? They proudly advised me, "the form of vitamin K2 mk7 we use is the ALL TRANS-FORM vitamin K2 that actually yields over 99% purity (the highest available)". Healthy Origins purchase their raw material called vitaMK7®'s from Gnosis Lesaffre in Italy, where it's produced using a patented biotransformation that doesn't rely on other chemical compounds! These details ensure a top quality formula that's 3rd party tested, cGMP compliant, non-GMO and SOY** FREE ! A top PREVentative MEDicine doctor who previously worked at John Hopkins hospital as the head of their preventative medicine instruction program, recently speculated that a minimum 400 mcg vitamin K2mk7 daily dosage may be required, and thats what many recent studies used, before any effect was measurable. 2 capsules of this supplement daily delivers 400 mcg of K2mk7 and provides 4k IU. of the included Vitamin D3 daily. That is an ideal level of D3* for me, I need 4,400 i.u. of D3* daily. *Please be advised EVERYONE'S Vitamin D3 needs to reach the recommended 40 -80 level of 25 ohd hydroxy D3 are different! Your personal vitamin D3 requirement is much more variable based on your age, weight, diet, sunlight exposure and what your current base 25 ohd hydroxy D3 level is. Ask your doctor what your 25 ohd hydroxy D3 level is, so you know where to start and if any supplementation is required! I switched to the enhanced 200mcg K2mk7 & 2,000 i. U. Vitamin D3 combo almost 2 years ago. At the new suggested 400mcg.minimum dosage that is being used in many current studies, and in additional research studies that used upto 3 grams daily for 3 months, it hasn't revealed any harmful side effects. UPDATED: Ongoing efficacy research Cardiovascular and preventative medicine experts recommend not relying on Vitamin K2mk7 to improve your cardiovascular health. Even if K2mk7 removes calcium from your arteries, several respected preventative medicine MD/ Phd experts question why would you want to do that anyway? They advise CALCIFIED plaque is stable and ISN'T known to be a great danger, unlike SOFT plaque, which is unstable and IS known to be a GREAT DANGER, but so far there is no evidence K2mk7 has any effect on soft plaque ! Additionally, cardiovascular disease prevention experts recommend improving your DIET and physical FITNESS first, it will have a far greater effect on your cardiovascular health than any supplement. If that doesn't help enough, they advise newer prescription drugs are the next helpful option. Hoping vitamin K2mk7 can FIX the damage of a BAD lifestyle isn't justified by ANY scientific medical EVIDENCE available at this time ! The science is ongoing but INCOMPLETE, and all the Internet influencers HYPOTHESIZED hyped benefits are UNPROVEN. Vitamin K2mk7's effects are still LARGELY unknown. They're limited to what science has revealed thus far, NOT MUCH ! **FYI ! CLARIFICATION regarding any SOY CONTENT: The label says it's a SOY FREE product, even though the the ingredient list says it contains NATTO, which in this product is DERIVED from soy, not from chickpeas. HOW IS THAT POSSIBLE? When asked this question, The executives at Healthy Origins explained: "This answer is a bit nuanced. Non-GMO Soy is used in the Natto fermentation process but during the process the SOY is COMPLETELY CONSUMED making the material COMPLETELY SOY FREE. After that point the material goes to ITALY where the K2 is extracted and PURIFIED. The purification of the K2 takes several steps which also ENSURES there is NO SOY in the final product. After further TESTING of the finished product it is CERTIFIED as a NO-SOY PURIFIED K2”. Great explanation, thank you Healthy Origins for providing this detailed clarification ! Read more
