Muscle Relax contains high concentrations of magnesium and calcium. These two minerals are essential for a strong skeleton and healthy bones, but they also have a favourable effect on the nervous system, muscle function and the electrolyte balance. Often magnesiumis not present in sufficient quantities in the feed. Muscle Relax contains the best absorbable form of magnesium, namely magnesium citrate. A shortage of magnesium can lead to muscle cramps and impaired nerve stimulation, resulting in tense reactions and increased excitability.
