Stamina-Extra is a patented, pharmaceutical grade, liquid L-Carnitine supplement for dogs that supports healthy muscle function, energy metabolism and athleticism in dogs. Stamina-Extra uniquely combines L-carnitine with MAH magnesium, which serves to facilitate absorption and works synergistically with L-carnitine to support muscle performance, electrolyte balance and energy metabolism. Used every day, Stamina-Extra supports adaptation to exercise, helping your dog to become stronger and fitter. Stamina-Extra also supports muscle relaxation and recovery and is suitable for dogs prone to post exercise tension. For working or competing dogs, Stamina-Extra supports stamina and muscle performance. It is best given every day to aid fittening, but can also be given for a short term need. For racing greyhounds, agility or similar, it is best to start feeding Stamina-Extra three weeks ahead of a period of competition. For overweight dogs, Stamina-Extra supports healthy glucose metabolism and handling. It may also help to promote the use of fat as an energy source, thereby improving energy levels and encouraging weight loss.
