    • "Dev from Winston & Porter recommended to try Nourish + C Max Strength Dog Supplement which I did with a lot of skepticism, as I don't believe any of these supplements work. HOW WRONG was I! It is unbelievable how Tia

      has changed after a few weeks, everybody thinks I have a new 2 year old dog."


      Richard, Jersey


      A very Comprehensive Dog Supplement containing High Levels of MSM, Chondroitin Sulphate, Extra Strength Glucosamine HCL, Hyaluronic Acid (HA) and Omega 3’s to soothe aching joints (see levels below). Together, these SUPER 4 ingredients form a binding agent which means less of the Essential ingredients are excreted from the body. So, more of the good stuff stays to do its job. 



      QUADRUPLE ACTION Containing:

      1. High Strength Glucosamine for dogs (HCL) - Glucosamine promotes healthy cartilage and is the actual joint lubrication.

      2. High Levels of Chondroitin for dogs - Chondroitin attracts fluid to your dog's joints to lubricate the dry cartilage.

      3. High Levels of Methylsulfonylmethane (MSM for dogs) 

      4. Hyaluronic Acid (HA) - HA is a gel-like water holding molecule that is the space filler and cushioning agent in all mammals. HA cushions joints, nerves, hydrates skin and hair. It works as a shock absorber lubricating the fluid in the joint tissues as well as stabilising its breakdown.


      • Encourages healthy tendons, ligaments, cartliage and 
      • Assist with dog joint stiffness and mobility.


      You should start to notice a marked difference within 2-3 weeks.

      Feeding Instructions:

      Small dog (0 - 15 kg eg. Jack Russell) 

      Half measure per day (20 grams approx)


      Medium Dog (15 - 40 kg eg. Spaniel)

      Mix with water to make a porridge type consistency or mix in with wet food. Alternatively, sprinkle on wet or dry food.


      Recommended Loading amount: Double the measure for the first seven days acording to the size of your dog with the very first pouch. Although this is not compulsary we recommend this to achieve best results. This will affect how long the first tub lasts and may last less than 30 days.

      Please Note: 30 Days supply is based on a daily maintenance measure recommended above dependent on the size of your dog, so lower measured amounts will last longer than 30 days and higher measured amounts will last less than 30 days.
