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.

A good choice for vitamin K2, especially when taken with D3. I work on my feet and began feeling discomfort in my knees, but after two months of use, that discomfort has completely disappeared. I would highly recommend it.
