Flex-N-Free is a food supplement that benefits many systems within the body of dogs but is primarily focused on supporting joint normality. Flex-N-Free is made with the highest quality scientifically-proven, natural ingredients. Flex-N-Free is human food grade and extremely gentle. Generous amounts of the most expensive ingredients are supplied. Everything is in proportions equal to what is recommended for humans. The 220 gram bottle provides daily supplementation to rejuvenate or maintain in top form a fifty pound dog for one month. Since the flavoring is Argentinian beef liver that is not irradiated from cows that are naturally grazed without hormones, antibiotics, or other chemical amendments, dogs love the taste and the liver is good for them. Joints, ligaments, and tendons metabolize and heal slowly. We guarantee significant improvement in less than a month. Ingredients
