Vitamin K may reduce knee pain
Associations Between Dietary Intake of Vitamin K and Changes in Symptomatic and Structural Changes in Patients With Knee Osteoarthritis.
Moderate relevance for clinical application
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.

Knee pain reduction
The importance of vitamin K for blood clotting is well-known, but it also maintains bone, cardiovascular, and nerve health. K2 contributes to a healthy skeletal system. After using it, my knee pain subsided and bruises ceased to appear. The packaging quality is impressive, and all the ingredients are natural.
