This has been such a great supplement. I take this with vitamin D and magnesium. Taking all three of them does make a difference. These are small and easy to swallow. No taste or burping it up. Great for senatuve stomach. Read more

This is a great supplement to pair with Vitamin D3 and I think Sports Research makes an excellent quality product. However, they recently changed the packaging design for the worse. While it's visually stylish, the bottle is less compact and a bit harder to open. I hope they'll consider going back to the old form factor while keeping the sleek newer graphic design -- best of both worlds. Read more

I have been using this Sports Research K2 MK7 for 3 years daily since it has added coconut oil for better absorption and is made from fermented chickpeas and not natto without all the fillers of other brands as well. I see that it no longer contains carrageenan since 2/2017 as some other old reviews mentioned. My dentist is going to go out of business if I keep using it as I've had far less plaque and no cavities and far less time in the cleaning chair. Hopefully my arteries arent clogged as much with calcium deposits anymore as well. Magnesium converts vitamin D into its active form so that it can help calcium absorption. Magnesium also stimulates the release of the hormone calcitonin, which helps to preserve bone structure and draws calcium out of the blood and soft tissues back into the bones where it is needed to build healthy bone structure. Vitamin K is what activates the calcitonin and matrix Gla protein to help improve bone mineralization. Vitamin K is like the ignition that turns the machine on - shielding the body from excess calcium. Once turned on, matrix Gla protein grabs calcium. The majority of Americans are vitamin K deficient, especially in the menaquinone (K2) variety which is found in foods such as natto (fermented soybeans) that are not eaten regularly in an American diet. Menaquinone-7, or MK-7, is the most biologically active and available form of vitamin K2 and Sports Research is the one I use for the supplementation. As you increase the dose of Vitamin K2 above 100, the activation of calcitonin increases in line with the dosage. One of the simplest ways to explain vitamin K2's importance is to say it has two crucial functions having to do with cardiovascular health and bone restoration. It helps prevent osteoporosis and hardening of the arteries. It directs calcium to places like your bones to make them stronger, and your teeth to help prevent cavities. It also prevents calcium from going to the wrong areas, such as to your kidneys, where it could lead to kidney stones, or your blood vessels, where it could lead to heart disease. A few other less known benefits: Optimizing sexual function by increasing testosterone and fertility in men, and decreasing androgens, the male hormones, in women with polycystic ovarian syndrome (PCOS) Creating insulin to stabilize your blood sugar (keeping your system sensitive to maintaining correct amounts), protecting against diabetes and helping to prevent metabolic problems associated with obesity Suppressing genes that can promote cancer while strengthening genes that promote healthy cells Enhancing your ability to utilize energy as you exercise improving overall performance A study in Rotterdam involving 4,809 Dutch adults determined that those with the highest vitamin K2 intake had fewer heart attacks, a lower aortic calcification risk and the lowest death rate, altogether.

I wrote this review about 5 years ago. Today I am still healthy with 2 Stents in my LAD and my arteries clear of Calcium. I even took a Full Force Treadmill Stress Test in my effort to renew my FAA physical to get back to flying small airplanes. This product really works. I have only one complaint, to remove Calcium Plaque or to cure Osteoporosis, you need to take ten of these capsules each day. One or two has no effect. If you search EBAY.uk you will find sellers of 365 Vitamin K2, 500mcg tablets for only $35 dollars. It is time this retailer sold a larger bottle of a higher dose of Vitamin K2 for the same price. This product removed plaque from my arteries. Two years ago I experienced a burning sensation in my chest. It was midnight and the wife and I had just watched a movie on TV and were preparing for bed. My age is 78 years old. My wife drove me to the emergency room of our local hospital. The doctor had been a cardiac nurse at the same hospital and recognized the symptoms as a possible blockage of my heart arteries. She sent me up to the Cardio ward and the next morning I was taken into the Catheterization Lab. The surgeon went into my heart via a vessel in my arm. Injecting dye he could see a major blockage in the LAD artery. The one called the 'Widow Maker." Calcium and cholesterol plaque had created an area of inflammation beneath the plaque and the inflammation (think of a pimple or a cyst) had erupted and the gunk from the infection was almost totally blocking the blood flow in my LAD artery. If you look up the symptoms of LAD blockage you will find the usual first symptom is 'SUDDEN DEATH.' I was one lucky guy. Thank God for my astute ER Doctor. Only the strong pulse with every beat of my heart was forcing blood by the blockage. The doctor was amazed and told me I was lucky to be alive. He installed two stents to force the gunk into the artery wall. He explained he would prescribe medication that would wash the gunk out of the artery and I would continue my life. He also noted that two other major arteries were blocked he estimated 60% and 65%. He said he couldn't install stents there until the blockage reached 75% or until one of the two caused a heart attack. That bothered me. I asked what I could do to reduce the plaque, he said there was nothing I could do to reduce the plaque but taking a Statin drug and living a healthy life would prevent the blockage from increasing. Not satisfied with that answer I went on a search of the internet and found a lot of information. YouTube was the number one source. There I found cardiologist who were not practicing consensus medicine dictated by the drug companies. Many recommended Vitamin K2 mk7, others recommended All Natural Vitamin C. I decided to try both. A friend recommended I obtain a calcium score. When I asked my cardiologist for a Calcium Score prescription he told me I was wasting my money. The Catheterization Xray film was proof my Calcium Score would be extremely high. After taking the two supplements for 6 months I asked my cardiologist again for a prescription. This time he gave me one, but with the caution that to expect an extremely high score. I went in for the procedure and two days later my cardiologist called. He said he had my score. I asked was it extremely high? He said no. But, he said it was elevated. My score was 940. Extremely high would have been above 2,000. He would not credit either supplement with my success. He doubted the accuracy of the Calcium Score but could not remember when he had ever doubted the results in the past. Today, my friend who is the same age and shares a similar life style came by. His Calcium Score two years ago was a little above 3,500. He had also taken the two supplements for 8 months. Today he got the results of a recent Calcium Score. he was down to 2,200, a 25% reduction in arterial plaque. A cause for celebration and continuing taking this Natural Vitamin C and this Vitamin K2 mk7 with Vitamin D. Read more
