DMG (Dimethylglycine) is produced naturally in both humans and animals. It can boost the immune response by over 400%. DMG is used to support proper immune response, cardiovascular and skin health, glucose metabolism as well as proper nerve and brain functions. DMG can support your dog, bird or cat's immune system so that the animal has greater protection and stays healthier. For athletic dogs (i.e., greyhounds, border colliers, hunting dogs, and other active working dogs), DMG reduces lactic acid buildup so muscles take less time to recuperate. DMG helps the body use nutrients more efficiently at the cellular level, and better utilizes oxygen at the cellular level to support respiratory function.* Each ml. provides 100 mg N,N-Dimethylglycine (DMG).Each drop provides: 5 mg N,N-Dimethylglycine (DMG), .5 ml = 10 drops.
