Max Relax contains tryptophan, which is used to produce serotonin and melatonin. Dogs with low levels of serotonin may be anxious, stressed and impulsive. A tryptophan supplement in the dog's daily diet can increase serotonin levels and lead to more balanced behaviour. Melatonin helps to reduce anxiety and has a calming effect. Max Relax also contains thiamine (vitamin B1) and magnesium, which also contribute to the formation of serotonin and melatonin. Max Relax is fed to improve the dog's ability to relax and handle stressful situations. It can be given as a preventative measure before an expected reaction or as a daily supplement in combination with remedial training. It can be given to dogs that become stressed by new situations, a change of environment or loud noises such as gunshots or fireworks. Use: For dogs that show anxious or stressed behaviour. For dogs that suffer from separation anxiety or are stressed by a change in their environment, loud noises or fireworks. For dogs with passive or withdrawn behaviour. 450 g.
