It is a dietary supplement that has been made from turmeric, black pepper and phosphatidyl L-serine. Curcumin found in the root of turmeric is the key active ingredient of this plant and is responsible for its bright yellow colour. Curcumin can inhibit compounds involved in joint pain. To relieve joint discomfort such as stiffness, turmeric is often combined with glucosamine sulfate. Turmeric is also increasingly being used in formulations to improve back problems. Pepper has been added to this product for proper absorption of its active ingredients.
