More-Mag® is the simple solution to magnesium deficiency for horses of all disciplines, including racing. Australian pastures are often magnesium deficient and exercise compounds the issue by further depleting magnesium levels. More-Mag® provides an easy,ready to use solution - just pour the dose on the feed and the job is done! More-Mag® contains magnesium pidolate which is why it last for longer than traditional forms of magnesium. One More-Mag® dose poured on to the feed will last for up to 10 days. Once More-Mag® is fed to your horse, the full amount of magnesium is available right away. This means there is no need to build up to the appropriate dose rate over a period of days. In addition, if you or your horse become sick or injured, you can cut the dose immediately and reintroduce it when your horse has returned to work.
