Kirkland Signature Triple Action Joint Health is a dietary supplement designed to support joint mobility, flexibility, and comfort. The formula features UC-II undenatured type II collagen, a patented form of collagen that maintains its biological activity because it is not denatured by heat or chemicals. Unlike traditional glucosamine and chondroitin supplements that require multiple large tablets daily, this product delivers effective joint support in just one small coated tablet per day.

Each tablet contains 40 mg of UC-II proprietary cartilage blend derived from chicken cartilage, along with 5 mg of boron (as boron glycinate) to support bone health and 3.3 mg of hyaluronic acid (as sodium hyaluronate), which exists naturally in joints. Clinical studies involving both subjects with osteoarthritis and healthy volunteers have demonstrated that taking a daily 40 mg dose of UC-II supports knee range of motion, knee extension, and knee comfort while exercising.

The product is USP Verified by the United States Pharmacopeia, an independent scientific nonprofit organization that sets strict quality and purity standards for dietary supplements. The tablets are small (approximately 0.52 inches) and easy to swallow. The supplement is free from shellfish, gluten, wheat, lactose, soy, milk, yeast, nuts, added sugar, and artificial flavors. For best results, daily use is recommended, and the supplement can be taken with or without food.
