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.

No kidney stones

This is the best form. I had been on steroids for seven consecutive bouts of bronchitis, which made my bones brittle. I ended up breaking a rib and puncturing a lung. My chiropractor recommended taking vitamin K2, saying it could remove calcium from arteries and kidney stones, directing it back to my bones and teeth. Since I started this, I have had no kidney stones and have seen noticeable improvements in kidney pain!
