Menaquinone-4 aids heart recovery
Potential Cardioprotective Role of Menaquinone-4 Against Cardiac Ischemia-reperfusion Injury.
Strong focus on cardiac health
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.

Menaquinone reduces heart attack risk
Dietary intake of menaquinone is associated with a reduced risk of coronary heart disease: the Rotterdam Study.
Study strongly supports vitamin K2 benefits
We explored the effect of dietary intake of menaquinone, commonly known as vitamin K2, on heart attack risk and overall heart health. The investigation drew on data from the Rotterdam Study, tracking 4,807 individuals who did not have prior heart attacks.
Through careful analysis, we observed a noteworthy finding: people who consumed higher amounts of menaquinone had a significantly reduced risk of coronary heart disease (CHD) and all-cause mortality. Specifically, those in the mid to upper intake levels of menaquinone exhibited a risk reduction of 27% and 57% for heart-related deaths compared to those with lower intake.
Interestingly, we found that menaquinone intake also seemed to correlate with lower instances of severe aortic calcification, suggesting its potential role in preventing vascular issues. On the other hand, our analysis indicated that phylloquinone, or vitamin K1, did not show any significant relationship with these health outcomes.
These findings underscore the importance of adequate menaquinone consumption as a potential strategy for heart attack prevention and cardiovascular health improvement.

Ekg improvement
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.

Magical vitamins
Vitamin K2 in MK-7 form is necessary for calcium absorption and strengthening bones. I take it daily with vitamin D3 and have noticed improved energy and mood, alongside better bone health, which can crucially aid in avoiding heart attacks.

Essential combination
I advise against taking vitamin D3 without MK-7 vitamin K2. D3 promotes calcium absorption in the intestines, but without K2, that calcium can calcify your arteries, leading to a heart attack. K2 helps direct calcium to the bones where it belongs, making MK-7 crucial for proper absorption.

Vitamin K importance
For those with high cholesterol, doctors prescribe statins, which inhibit vitamin K production in the liver. Additional MK-7 intake is essential, especially in fat-soluble gel capsules for better absorption. This form does not thicken the blood, even at high doses. Numerous studies support potassium's role in heart, blood vessel, and bone health, making it crucial for preventing heart attacks.
