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.

We explored the effect of vitamin K3 on fibrosis in lupus nephritis (LN), a serious complication of systemic lupus erythematosus. The study analyzed kidney biopsy samples and lupus-prone mice, looking particularly at the SIAH2-LATS2 pathway.

Our findings revealed that vitamin K3 can effectively protect against renal fibrotic damage by inhibiting the degradation of LATS2, a protein crucial for controlling fibrosis progression. This suggests a potential new treatment avenue for patients suffering from LN.

We explored the effectiveness of apixaban compared to vitamin K antagonists (VKAs) in preventing thromboembolic events in patients with antiphospholipid syndrome (APS).

In a study involving 152 patients, we tracked complications over a median of 53 months.

The results showed that thromboembolic events were similar between those on apixaban and VKAs, indicating no significant advantage for vitamin K treatment in this context.

Both treatments posed comparable risks for bleeding, suggesting apixaban might be a viable option for some APS patients.

Reduced hair loss

I began taking K2 (MK-7) to ensure proper calcium absorption with Vitamin D, as my doctor advised to avoid thrombosis. After starting K2 due to hair loss while on Vitamin D alone, my condition has improved significantly now. I take 200 mcg daily.

Better absorption

My family and I take Vitamin K-2 with D-3 as directed by our doctor. K2 ensures proper calcium distribution in the body, aiding bone health. The capsule is small and easy to take. We were also pleased with the quick delivery.

Prevention of calcification

I take calcium and Vitamin D but added K2 to prevent calcification. K2 assists in calcium and Vitamin D reaching the bones. The multivitamin I had was insufficient, so I’ll repurchase this product.
