The most active form of vitamin K2 supports bone and cardiovascular health. VitaMK7® Dietary Supplement MK-7 from Jarrow Formulas® is produced through natural fermentation with hay bacillus (Bacillus subtilis subspecies natto) and is far better absorbed than vitamin K1 found in spinach. MK-7 acts longer than both vitamin K1 and MK-4, providing more effective carboxylation of specific proteins vital for bone formation and cardiovascular health. I'm pleased to report that the rashes on my face disappeared. I take one capsule twice daily.

We examined how Menaquinone-4, a form of vitamin K2, could help protect the heart during a critical event known as ischemia-reperfusion (I/R) injury, which often occurs after heart attacks. In our study, we used thirty-two rats, dividing them into three groups: a control group that experienced I/R without treatment, a group that received MK-4 before the injury, and another group that got MK-4 at the beginning of the recovery phase.
By using a specialized apparatus to assess heart function, we measured various indicators of heart health, including the pressure the heart could generate and rates of heart contractions. We also examined markers of heart damage and stress, like enzymes and inflammatory signals.
Our findings were promising. The group that received MK-4 after the I/R injury showed a significant reduction in the size of heart damage, alongside improved heart function. This group also had lower levels of markers related to heart stress and damage, indicating that MK-4 might help the heart recover from the stress of a heart attack. Overall, these results suggest that vitamin K2 could be a valuable ally in enhancing heart health during recovery from ischemic events.

This product has greatly helped with cleaning arteries. My husband, who has undergone three heart procedures, was surprised by how "perfect" his ECG turned out during a check-up after starting it. His blood pressure has also improved markedly, possibly due to less artery blockage, reducing the risk of heart attacks. He occasionally skips a day as it builds up in his system.

We explored the effect of vitamin K1 (VK1) on kidney stone formation by treating rats for eight weeks. Our observations showed that VK1 significantly reduced crystal formation in the kidneys.
It boosted levels of matrix Gla protein, which plays a crucial role in preventing crystal deposition. We noticed that VK1 even countered the negative effects of warfarin on cell viability. Overall, our findings suggest that VK1 could be a promising treatment to help prevent kidney stones.

There is a result! This dietary supplement contains a suitable dosage of vitamin K2, important for those who take high doses of vitamin D3. Since beginning my intake, I've noticed that my vitamin K levels in the blood are rising. It’s essential to accompany vitamin D with K2 to prevent kidney stones. Take it with fatty food as it's fat-soluble.

Since taking this once a day for several months, my ankles are not as blue, and my legs do not tire as easily. I have serious varicose veins and am aware it thickens the blood slightly if you take warfarin, which I used to take. I switched to apixaban, which spares some vitamin K, and I’ve noticed quicker hair and nail growth, too.

To explore vitamin K2's effect on osteoporosis, we conducted a thorough analysis of nine studies involving 6,853 participants.
The findings suggest that vitamin K2 significantly improves bone mineral density (BMD) and reduces certain bone markers.
While there were increased adverse reactions, they were not serious. Overall, this suggests that vitamin K2 can be a beneficial and safe option for postmenopausal women managing osteoporosis.

This product has been incredible for preventing heart disease. I take it alongside omega 3-6-9 and calcium. Since starting, the occasional minor chest pains I've had for the last 20 years have significantly reduced or stopped. If it performs as indicated, in moving calcium into the bones rather than arteries, it is certainly worth considering.

We explored how treating patients with osteoporosis with vitamin K2 and D3 could influence back pain and spine fusion rates following surgery. In this study, we included patients who underwent spinal surgery for lumbar degenerative disorders. Some received a combination of vitamin K2, D3, and calcium, while others were treated with only calcium and vitamin D3.
The results showed that those who took vitamin K2 along with their other treatments had improved fusion rates and experienced less back pain. Furthermore, clinical symptoms improved, and there was a marked promotion of bone health within six months after surgery. Notably, the administration of vitamin K2 also helped maintain bone mineral density.
Overall, this research suggests that incorporating vitamin K2 alongside traditional treatments could be beneficial for individuals dealing with back pain related to osteoporosis. It opens the door for more studies on how we might better treat and manage spinal conditions in these patients.

We examined the effectiveness and safety of vitamin K antagonists (VKAs) in resolving left ventricular thrombosis in a group of 90 patients over 12 months.
While we found that 70% experienced resolution of the thrombosis by the end of the study, the presence of low left ventricular ejection fraction and aneurysms negatively impacted outcomes.
Overall, the rate of complications, including strokes and major bleeding, remained low during the treatment period, indicating that VKAs can be a viable option, though some patients may face challenges in resolution.

We aimed to discover how well PIVKA-II can predict treatment response in patients with non-AFP-secreting hepatocellular carcinoma (HCC) receiving systemic therapy.
By measuring PIVKA-II levels and assessing imaging after 8-12 weeks of treatment, we found a connection between PIVKA-II levels, tumor size, and treatment outcomes.
The study revealed a promising “50-50 rule” that can indicate prognosis based on PIVKA-II changes, making it a valuable marker for HCC treatment success.

K2 MK7 assists in the normal absorption of calcium and the strengthening of bones, as well as supports the maintenance of cardiovascular and nervous systems. At doses of D3 exceeding 5000 IU, it is crucial to take vitamin K2 MK7. Some substances essential for our body can only be synthesised with menaquinone. Vitamin K2 is recognised for its benefits in various bodily systems: it promotes cardiovascular health by directing calcium from the bloodstream to bone tissue, regulating bone density and blood clotting. Research has revealed that vitamin K2 can slow down, or even halt, cancer cell activity, showing positive effects on lung, pancreatic, bladder, and rectal cancers.

Vitamin K-dependent GAS6 enhances remyelination
We investigated the role of GAS6 in promoting remyelination, particularly in relation to vitamin K's effect on a type of receptor.
Our findings highlight that GAS6 needs to be modified through vitamin K for proper function.
When introduced to wild-type mice, this treatment significantly increased the number of myelinated axons compared to a control group.
However, in mice lacking the specific Tyro3 receptor, no significant improvement was noted. This indicates that Tyro3 is crucial for the effectiveness of GAS6 in aiding recovery for conditions like multiple sclerosis.
