Nutrition Information

Magnesium plays an important part in nerve and muscle function and can be helpful in calming horses and ponies.  Used daily, Magnesium can help to reduce difficult behaviour and produce a more relaxed approach to work.  Magnesium can also assist in attaining normal fat coverage in overweight equines, especially those with a cresty neck/fatty pockets.  Each daily serving provides 6g of bioavailable Magnesium Oxide per scoop.
