More-Mag® is the simple solution to magnesium deficiency for equestrian and racing horses. New Zealand and Australia have a large pool of sport horses from great genetic lines that are sought after around the world. But with the magnesium deficient soils in both NZ and Australia, the problem of magnesium deficient pastures and feeds is common.

Further confounding the problem of magnesium deficiency is the huge drain of magnesium by the horse during exercise. Both muscles and the nervous system drain precious magnesium. No matter what the discipline, all horses involved in equestrian, harness racing and gallops, and other horse sports too, are likely to become magnesium deficient. Many top trainers and equestrian horse owners use and recommend More-Mag® as an effective supplement to help horses keep a calm and steady head to stay focused during training and competition. More-Mag® then aids in muscle recovery afterwards. More-Mag® has no withhold so it can be used all year round.

More-Mag® contains magnesium pidolate which is why it lasts for longer than traditional forms of magnesium. One More-Mag® dose poured on the feed will last for up to 10 days. Most horses in work are fed More-Mag® once a week, and once fed, the full amount of magnesium is available right away. That means that there is no need to build up to the appropriate dose rate over a period of days because when you dose More-Mag® you know your horse will be able to draw upon the magnesium that it needs. In addition, if you or your horse become injured or sick, you can cut the dose out, and reintroduce it when the horse is back at the track, or in equestrian work.
