ProThrive™ Senior is designed specifically for the aging or arthritic dog. It contains our highest concentration of Microencapsulated Probiotics, Prebiotics and Digestive Enzymes which work together to improve your dog’s digestive health, resulting in a stronger immune system. In addition, Glucosamine, MSM, Hyaluronic Acid and Yucca Schidigera help with joint health and reduce swelling and pain due to osteoarthritis. Sea Kelp, Vitamin E and Vitamin C are added to aid in replenishing micronutrients that are deplenished during the aging process. ProThrive™ Senior supplements dogs with beneficial bacteria lost in modern, highly sanitized and processed food.
