Choose a supplement containing magnesium. The direct relationship between stress & magnesium is well documented. Poor magnesium status has been shown to cause a heightened stress response in horses. Research has shown that magnesium supplemented horses had lower heart rates in stressful situations, such as after transportation. Magnesium is safe and has no adverse effects so is ideal to use a calmer supplement.
However, some magnesium compounds are not absorbed very well by horses. This means that the magnesium can’t be absorbed and get into the bloodstream, so the calmer won’t work. Make sure that you read the label and choose your magnesium supplement carefully. Avoid supplements containing magnesium oxide as this is very poorly absorbed by horses and so won’t be effective. Choose a supplement containing magnesium aspartate hydrochloride as this is considered to be the ‘gold standard’ magnesium that is best absorbed by horses. Chelated magnesium is also well absorbed and an effective supplement.
Nettex Calmers contain magnesium that is bioavailable & quickly absorbed. Nettex Calmer Syringe Paste Boost & Calmer Maintenance Liquid both contain Magnesium Aspartate Hydrochloride the gold standard magnesium. Nettex Calmer Maintenance Powder contains chelated Magnesium which is also readily absorbed.
