Glyco-Flex III (now branded as Extra Strength Healthy Hip & Joint) is a veterinarian-formulated joint supplement for dogs, available in a 120-count bag of chicken-flavored bite-sized chews. The Stage 3 formula is designed for adult and senior dogs weighing over 30 pounds who need advanced joint support, including those experiencing pain, inflammation, arthritis, or reduced mobility.

Each serving delivers 1000 mg of glucosamine hydrochloride, 1000 mg of MSM (methylsulfonylmethane), and 600 mg of GlycOmega brand green-lipped mussel (Perna canaliculus) — a whole-food organism that is a natural source of glucosamine, hyaluronic acid, antioxidants, and omega-3 fatty acids. Additional active ingredients include DMG (N-N-Dimethylglycine) to support circulation and energy, manganese to aid collagen formation, and antioxidants including Vitamins E and C, selenium, L-glutathione, and grape seed extract. Clinical studies support that hind leg strength can improve in as little as four weeks of use.

Dosing follows an initial loading period of 4–6 weeks, after which dogs transition to a maintenance schedule. Dogs up to 30 lbs receive 1 chew daily during loading, while dogs over 100 lbs receive 5 chews daily. No prescription is required. Manufactured in the USA in an SQF-certified, FDA-registered facility. NASC quality certified. Contains no artificial flavors, synthetic colors, or preservatives. Store in a cool, dry place.
