Each package contains a 14 day supply of all the nutrients necessary to rebuild joints, and relieve aches and pains. The product is so effective because it contains JNT-A, an herbal blend designed to feed the structural system an reduce inflammation, Glucosamine - which research shows to rebuild cartilage and connective tissue around the joints, flax seed oil gelcaps - known to reduce inflammation, and an enzyme formula to assist the digestive system in absorbing nutrients for maximum effectiveness. Even though each packet contains a flax seed oil gelcap, we find that by adding an additional gelcap each time you take the packets, you will see faster results in reducing joint pain and increasing flexibility.
