Phycox MAX Soft Chews combine the ingredients in Phycox Soft Chews with increased amounts of phycocyanin and additional active ingredients for older dogs or dogs with advanced joint discomfort. The balanced blend of natural ingredients in Phycox MAX also helps improve and maintain total body health. Only Phycox contains Phycocyanin, a natural anti-inflammatory and antioxidant derived from blue-green algae. Phycocyanin is clinically proven to inhibit COX-2, an enzyme that causes inflammation, and is more effective — with fewer side effects — than similar ingredients in other joint supplements. Phycox MAX provides increased Phycocyanin and additional active ingredients to meet the needs of older and severely arthritic dogs. Pet owners and veterinarians alike trust Phycox for quality and effectiveness.
