Turmeric supplements are frequently used to improve the symptoms of several types of arthritis. This includes osteoarthritis and rheumatoid arthritis. In a small 2012 study of forty-five patients with rheumatoid arthritis, researchers found that taking five hundred milligrams of curcumin daily was more effective in reducing tenderness and joint swelling than a daily fifty milligrams of diclofenac sodium. Turmeric supplements with curcumin are also routinely used to relieve itching from chronic kidney disease. They have shown promise in reducing blood cholesterol levels as well. Many patients often use turmeric supplements to prevent and treat heart disease.
Studies have shown turmeric improves the functioning of the endothelium (the lining of the blood vessels). Endothelium issues can cause problems with the regulation of blood pressure and blood clotting. They are a major contributor to the development of cardiovascular disease. One study found the active ingredient in turmeric was as effective as physical activity in enhancing endothelial health. Other research concluded the ingredient was able to protect the endothelium just as well as atorvastatin, a prescription medication.
