Condition
Venous Thromboembolism (Blood Clotting)
Venous thromboembolism is a blood clot that forms in a deep vein, usually in the leg, and can break loose and travel to the lungs, where it blocks blood flow. Omega-3 fatty acids and vitamin D are the supplements people look at most, but little research on them for this condition has been reviewed here so far. Their mild effects on platelets and clotting are plausible on paper, yet no trial findings can be reported, so the evidence is too thin to say whether they matter.
