Mollichaff Calmer contains a balanced blend of fibre pellets, oat straw, dried grass, herbs, soya oil, vitamins, minerals, limestone and trace elements. Along with a carefully formulated combination of camomile, lemon balm and mint, Mollichaff Calmer supplies elevated levels of magnesium, as a diet deficient in magnesium can result in increased muscle contraction, making the horse less able to relax and more likely to become excitable or fizzy.
