Glucosamine occurs naturally in the body"s joints and cartilage and plays a key role in the structural system. As we age, our bodies become less efficient at manufacturing the elements necessary for healthy joint structure. Glucosamine works with nutrients like chondroitin to stimulate rebuilding and maintenance of cartilage. Now you can get glucosamine with the added nutritional benefits of una de gato (cat"s claw), one of the world"s foremost tonic herbs. Una de gato grows in the highland rainforests of Peru, where it has been popular for centuries. Una de gato provides nutrients to support the body"s structural system, plus it"s a premier metabolic tonic herb. Each capsule blends 400 mg of glucosamine hydrochloride with una de gato. Four capsules daily provide 1,600 mg of glucosamine. Take 2 capsules with a meal twice daily.
