Canine Joint Health Supplement

Our canine joint support supplements provide specific whole foods that supply what a dog's body needs to support and repair its own bone and connective tissue. With 100% bioavailable whole foods, Flex-Well K9™ supports your dog's ability to produce their own glucosamine, an amino sugar vital for forming and repairing body tissues.

Available in 60-serving bag (1 tsp. scoop included) 

    "This product was recommended to me by a friend who uses BioStar for her horses and dogs. I was a bit skeptical that I would see any improvement, but I gave it a try anyway. I have been using Flex-Well K9 for about a month. I can honestly say that my dog's energy has increased and his movement has improved. My husband has noticed the same changes, and my parents who were visiting recently mentioned the increase in my dogs energy over the last time they saw him 6 weeks ago. I would recommend trying this product if your dog suffers from joint-related issues.- Lisa

Very Impressed with Results!

My 7 year old miniature Aussie has been struggling since he was about 2 with an injury to his front leg. It flares up every time he plays frisbee, which he loves! He would limp and be sore for a few days. With this supplement he tolerates playing frisbee like a champ! I can’t recommend this product enough!

Great supplement

My 10 yr old Boxer just had TPLO surgery and I'm a firm believer that whole foods are the best medicine for healing and overall well-being. He is post surgery 3 weeks now and this seems to be helpful to his recovery. I will continue using Flex-Well after his recovery for overall health.

Good ingredients

My pup is still young so I’m giving it to her as a preventative because she is an extremely active young Lab and never stops. English Labs are supposed to be chill? Not this one. She’s an energizer bunny. I love that she’s getting the nutrients she needs with whole foods instead of synthetic supplements.
