With maxxiflex+ rest assured that we are giving your dog our best science in every dose. From the very beginning we focused on making our joint supplement the right supplement. Whether you buy directly from us or from one of our retail partners, you are getting the same supplement each and every time, because we know it’s our best. Our carefully chosen ingredients include potent anti-inflammatory and antioxidants agents. We start with the basic building blocks of proper joint care including glucosamine HCL, chondroitin sulfate, and MSM. Then we add in an additional layer of our own combination of supporting ingredients that have been shown to support comfortable joint movements, i.e. hyaluronic acid, hydrolyzed collagen, cetylated fatty acids, devils claw, bio active whey protein, and bromelain. Additionally, we guarantee that all the stated ingredients are present in the product at the date of manufacturing.
