SmartFlex® Senior

SmartFlex Senior was designed to support older horses in the 3 areas they need it most - joint health, digestive function and antioxidants for a healthy immune system.

For joint support, SmartFlex Senior provides 7,000 mg of Glucosamine, 500 mg of Chondroitin Sulfate, 50 mg Hyaluronic Acid and 12,000 mg of MSM. This formula contains the herbs Devil's Claw and Bromelain, as well as the amino acid Phenylalanine, to help manage discomfort. To support healthy digestion and weight maintenance, SmartFlex Senior provides probiotics, prebiotics and enzymes. And because senior horses benefit from extra antioxidants, this formula also contains Vitamin C and the powerful free radical scavenger Super Oxide Dismutase. This outstanding formula is a customer favorite!
