Stacy Wiegman, PharmD, Pharmacy, answeredChronic venous insufficiency is a condition in which the veins do not effectively return blood from the legs to the heart. Symptoms mostly occur in the legs and can include swelling, pain, color changes, and skin ulcers, among others. In one small clinical trial, 30 days of treatment with glucosamine improved swelling and other measures of this disease in 70 to 90 percent of the people studied. How this happens is not known. Further research is needed before recommending glucosamine to all people with chronic venous insufficiency.
