Product description


Rx Vitamins for Pets, MegaFlex for Dogs & Cats Powder provides several ingredients that may help your pet stay active by working to keep his or her joints healthy.

For example, one tablespoon of MegaFlex for Dogs & Cats Powder contains 1,000 milligrams of glucosamine sulfate. Notably, glucosamine could potentially aid in building cartilage, which is a form of connective tissue that cushions your pet,s joints.

This Rx Vitamins for Pets supplement also provides a form of sulfur called methylsulfonylmethane (MSM) that might work to slow down the nerve impulses that transmit pain signals. As a result, this product may act to relieve minor pain or stiffness.

Although dogs and cats of all sizes could potentially benefit from taking MegaFlex for Dogs & Cats Powder, this supplement may be particularly helpful for larger dog breeds that put more weight on their joints on a daily basis; markedly, the recommended serving size for a 100-pound dog is just one tablespoon daily!

Each bottle of MegaFlex for Dogs & Cats Powder by Rx Vitamins for Pets contains 600 grams of powder.
