Cosequin ASU Equine Powder is a professional strength, dual synergistic formula to help horses maintain healthy joints and cartilage. Cosequin ASU goes beyond the original Cosequin formula with the addition of avocado/soybean unsaponifiables (ASU), a potent ingredient to protect cartilage. The superior quality and specific combination of ASU with glucosamine and chondroitin has been shown to work better than glucosamine/chondroitin supplements alone. 1300g (80 days).
