VetriScience Extra Strength Hip & Joint Supplement for Dogs, GlycoFlex 3 – Vet Formulated Glucosamine, MSM & Green-Lipped Mussel Chews for Mobility, Flexibility & Joint Support, Chicken Flavor, 120ct

VetriScience® GlycoFlex® 3 Extra Strength Healthy Hip & Joint Chews represent Stage 3 of our comprehensive joint health program, formulated for dogs needing advanced support. This formula is recommended by veterinarians for geriatric dogs, working breeds, and as follow-up care after orthopedic surgery. Clinical research shows GlycoFlex 3 can increase hind-leg strength by up to 41% in just 4 weeks, making it one of the most trusted solutions for canine joint care. Each two-chew serving delivers 10 powerful active ingredients: 1000 mg glucosamine HCl (shrimp & crab), 1000 mg MSM, 600 mg GlycOmega™ brand Perna canaliculus (green-lipped mussel), 100 mg DMG, 50 IU Vitamin E, 24 mg Vitamin C, 10 mg manganese, 5 mg grape seed extract, 2 mg L-glutathione, and 0.002 mg selenium. Together, they support cartilage resilience, connective tissue strength, joint lubrication, collagen production, and oxidative balance. Unlike mussel powders or extracts, GlycOmega™ Perna utilizes the entire organism, preserving natural fatty acids and bioactives for superior results. Antioxidants (C, E, grape seed extract, selenium, glutathione) further promote immune health, detoxification, and a healthy inflammatory response. These bite-sized chicken-liver flavored chews are highly palatable, turning daily dosing into treat time. Manufactured in the USA in an FDA-registered, SQF-certified facility and carrying the NASC seal, GlycoFlex 3 guarantees clean, safe, and effective joint support with no artificial colors or fillers. Feeding directions are simple: initial 4–6 weeks: up to 30 lbs = 1 chew daily; 31–60 lbs = 2 chews daily; 61–100 lbs = 4 chews daily; 101+ lbs = 5 chews daily. Maintenance: reduce to 1 chew every other day for smaller dogs, or 1–3 chews daily depending on weight. With over 40 years of VetriScience expertise and 15,000+ veterinarians recommending our products, GlycoFlex 3 delivers clinically proven, veterinarian-trusted results—keeping your dog comfortable, mobile, and active year-round.
