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.

I took vitamin D at a dosage of 10,000 IU for three months, which resulted in the formation of kidney stones. After addressing this with another herbal remedy, I now take vitamin K2 alongside vitamin D at 5,000 IU to prevent further stones. All medications were prescribed by my doctor, so it’s important to rely on professional advice rather than just others' experiences.
