   This is apparently the right version of K2 – so it’s the one I’m using. No real way to gauge its effectiveness.

   I like that the ingredients are natural and not synthetic. I was looking for a K-2 supplement to go along with my vitamin D3 supplement. I eat enough calcium rich foods so my calcium is good but I needed the K-2 to help with getting the calcium to my bones where I need it. Circulation is a big issue not only for me but for other family members as well. I’m hoping this brand of K-2 works as I have only started taking it today but will continue taking it every day along with my vitamin D3 supplement. Thank you Smarter vitamins. If the K-2 works I will definitely be a life long customer.

   I check softgels of any supplements I buy by first chewing several. The taste was very bitter. The ingredient that caused the bitterness was very likely the kale, because I’ve had no problem with any of the other ingredients in other products. I will not reorder it, and will throw these out. The price was reasonable, but not the taste.

   “Smarter Vitamins” vitamin K2’s product is made with K2Vital which means the MK-7 is in its trans form. not the inactive cis form. MK-7 can exist as geometric isomers (cis and trans forms), but the trans form is the active form.

   So, this product sold by “Smarter Vitamins” is far more useful than K2 MK-7 products sold by others who don’t tell you what you’re buying.

   I use vitamin K2 with menaQ7 because it is helpful for your heart by inhibiting calcium deposits in the arteries and blood vessels, thereby contributing to improved cardiovascular health, to your bones by helping the body make use of calcium to build healthy bones and for the kidney – it is also available in small doses of 45mcg. I have been using a different brand but decided to try this brand based on the manufacturer’s description. I haven’t tried it yet, but have been using K2 with menaQ7 for more than 5 years. I think I may continue to purchase this brand.

   My cardiologist recommended that I add Vitamin K to my list of supplements. I’ve been taking this supplement now for nearly seven months. I’m due for my annual bone density scan in the next few weeks. I’m hoping the Vitamin K will have an effect. I will update with my results.

   I take D3 as a supplement and understand that K2 should also be taken to prevent unwanted calcification in vessels. There are differing opinions on supplementation and D3 to K2 ratios. Just as there are differing opinions between different medical bodies internationally on what constitutes deficient vs. healthy D levels. Many of the combination D3 K2 products seem to have ratios that are lower than some of the recommendations. So, with these small 100 mcg. capsules you can reach whatever ratio you wish by combining with a D3 product that does not contain K2.
