Betamag Forte by Equistro is a liquid supplement for horses or ponies. This liquid contains magnesium and zinc which help reduce reactions to stress in your horse. Magnesium plays an important role in many processes such as energy production and glucose metabolism. It also has a relaxing effect on nerves and muscles. Zinc has an important role in tension; the horse's zinc levels drop during tense situations. Equistro Betamag Forte replenishes these reserves. In addition, zinc has a positive effect on hoof hardness, metabolism, growth and coat quality of your horse.
