Vitamin K1, which is found naturally in leafy greens and some other vegetables, has been increasingly scrutinised in terms of its relationship with arthritis in a supplement form. So a team set out to examine whether vitamin K1 supplements are useful for reducing inflammation in 58 people with rheumatoid arthritis.

Half of the volunteers received vitamin K1 for eight weeks and the other half were given a placebo. Disease activity scores and blood levels of some inflammatory markers were assessed at the start and end of the study, and no differences were found between the groups. The research group concludes:

“Vitamin K1 supplementation at 10 mg/day for eight weeks had no significant effects on blood biomarkers of inflammation and disease severity of patients with rheumatoid arthritis compared with the placebo group.”
