We evaluated the effectiveness of vitamin K antagonists (VKAs) in treating left ventricular thrombosis (LVT). Over a year, a cohort of 90 patients was observed for LVT resolution and complications.
By the end of the study, approximately 70% of participants saw their blood clots resolve, with lower success rates linked to factors like reduced heart function. While VKAs showed promise, the treatment's safety profile was also notable, with few severe complications reported.

I took vitamin K2 following a body cleanse with Triphala. After two weeks, I experienced severe pain in my upper abdomen and struggled to sleep or sit. My dyskinesia made it worse. Remembering that K2 aids in liver disease recovery, I tried it. After taking it, the pain vanished and I slept well. I also noticed that my friend with stomach issues benefited from it, as it helped alleviate her pain too. I believe this vitamin is essential not just for bones but also for gastrointestinal health.

I am undergoing megavitamin therapy. My husband suffers from hay fever, and I have severe allergies to rhinitis, so I commenced taking vitamin D3 at 30,000 IU. A dose of 100mcg of vitamin K2 is necessary for every 10,000 IU of vitamin D3, hence they are combined. Although some preparations contain both D3 and K2, I find it a bit expensive, so I appreciate being able to purchase them separately. My nose often feels blockaged before bedtime, but now it is completely clear. Thank you.

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.

Just what I needed! Since I began taking K2, my vitamin D levels have risen into the normal range. I previously took vitamin D alone for a year with no changes. After adding K2, my levels increased over 100 points within three months! I found the mk7 version caused anxiety and insomnia, so I switched to mk4 without any negative side effects. I'm very pleased with this product and will order it again.

We observed an interesting case involving a 1-month-old infant with significant bruising and severe vitamin K deficiency. This deficiency led to spontaneous thymic hemorrhage, which was identified along with coagulopathy during medical evaluation.
The child had not received vitamin K prophylaxis at birth, which likely contributed to the outcomes we saw. Fortunately, after administering vitamin K, the coagulopathy improved. This case highlights the essential role of vitamin K in preventing serious bleeding issues in infants.

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.

We explored whether vitamin K2, a form of vitamin K, could help in managing high cholesterol and atherosclerosis in rabbits with elevated cholesterol levels.
Over a span of ten weeks, we administered different doses of vitamin K2 to rabbits fed a cholesterol-rich diet.
The findings were encouraging; the vitamin K2-treated rabbits had significantly lower cholesterol levels compared to a control group.
Additionally, it seems that vitamin K2 at moderate doses helped slow down the development of atherosclerosis without any adverse effects on blood coagulation.

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.

We explored the potential benefits of low-dose vitamin K2, specifically menaquinone-7 (MK-7), on bone health in healthy postmenopausal women. Over a three-year study with 244 participants, we found that MK-7 significantly improved bone mineral density and strength, suggesting it could mitigate age-related bone loss.
While the results are promising for postmenopausal women, more research is needed to determine if these findings apply to other groups, such as men and children.

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 explored the link between dietary vitamin K intake and knee pain in patients suffering from osteoarthritis. Over two years, we followed 259 participants, measuring their vitamin K intake and knee symptoms using established assessment tools.
Our findings revealed that higher vitamin K intake was associated with a noticeable reduction in knee pain. For those with severe pain at the beginning, the benefits were even clearer. However, we did not find significant impacts on knee structure based on MRI scans.
This suggests that further trials on vitamin K supplementation for knee pain may be valuable, especially for those experiencing severe symptoms.

One of the few products that is exclusively MK-4. While many emphasise the MK-7 form of Vitamin K2 for its calcium-enhancing qualities, I prefer MK-4 as it is found in the brain and regulates gene expression uniquely. It activates genes that maintain cell health while deactivating those that promote cancer. Animals convert other forms of Vitamin K to MK-4, but this process is inefficient and varies by genetics, making MK-4 supplementation potentially beneficial. However, some argue that MK-4 supplements are synthetic and may have low bioavailability.
