Phycox Soft Chews provide an easy way to give dogs the benefits of Phycox in a great-tasting treat. Phycox contains a patented formula that provides preventative care and helps relieve the symptoms of joint discomfort with a single daily dosage. 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. Pet owners and veterinarians alike trust Phycox for quality and effectiveness.
