Q. There are a lot of supplements out there for my dog’s joints. What should I know?
A. We have known for a long time that certain nutrients and herbs help with joint health by reducing inflammation, repair, and lubrication of the damaged joints. Now there are so many formulas on the market it is difficult to know which are worth the money or not. I will talk about the major ingredients found in these products.
Glucosamine and chondrotin have been used for joint health for decades. A common source is from New Zealand’s Green Lip Mussels (Perna canaliculus). This mussel is rich in glucosamine and chondroitin, omega 3 fatty acids, EPA and DHA, and ETA, eicosatetraenoic acid, which has strong anti-inflammatory properties. Another source commonly used is the sea cucumber.
MSM (methylsulfonylmethane) is a naturally occurring easily absorbable sulfur. Sulfur is essential for cell membrane health. This compound is an antioxidant, heals and allows rejuvenation of joints, reduces pain and inflammation. Many commercial joint supplements contain MSM.
Hyaluronic Acid (HA) has been used as a joint injection to decrease pain and increase a cushion to protect the cartilage. It is a type of glycosaminoglycan (GAG). It is a bigger molecule than glucosamine and is found naturally in the body to help wound healing and acts a shock absorber in joints. This is now found in many joint products.
Omega 3 fatty acids are known for anti-inflammatory properties. Joints are no exception. Omega 3’s eicosapentraenoic acid (EPA) and docosahexaenoic acid (DHA) are the major fatty acids with anti-inflammatory effects. There are many products available but the importance of the amount of EPA and DHA in each serving will make the difference for pain reduction. Your veterinarian will know the appropriate dose for your dog’s weight.
Turmeric has the active compound, curcumin. There are few studies on its efficacy. Results show promising anti-inflammatory properties. The dose suggested is 1/8-1/4 teaspoon per ten pounds body weight. Use with caution because your best friend can develop GI distress.
Other herbs used to reduce inflammation are Astaxanthin (red algae), and Boswellia (Indian Frankincense). Both are used to decrease inflammation and joint pain.
Nutritional substances, such as natural eggshell membrane (NEM), microlactin, a milk protein from cow’s milk, indentured collagen type 2 (UC II) from chicken sternum cartilage, tetra decanol complex (TDC) from beef tallow, avocado and soybean unsaponifiables (ASU), are all used in joint supplements to decrease inflammation and reduce joint damage.
CBD is being studied by universities for its efficacy. We have seen the fruits of this research and now have a better idea of appropriate dosing. Not all CBD products are the same. It is important to look at the certificate of analysis to know what you are buying.
Deer velvet antler has been used in traditional Chinese medicine for centuries for reducing pain, inflammation, and healing of joints.
There are so many formulas available. Some have research behind them, are being studied now, or are antidotally being promoted. Take away points: Give any nutritional supplement at least a month to assess the effect on your dog. What works on your friend’s dog may not work well for your dog. Look for products made for dogs versus human products because the dosing is usually wrong for your best friend. Many times, the amount needed is more than what a person takes. Some of these substances can have adverse reactions. Do not try to make your own product without the help of a professional. Always discuss with your veterinarian which products and supplements are best for your dog. Also, if using supplements, be sure to give the list with doses for your best friend’s medical record.
