magnesium oxide – light

Image of magnesium oxide for horses

We generally avoid supplements, believing that our horses will get their nutritional needs best from a managed healthy balanced diet and understand that excesses can cause as much imbalance and problems as deficiencies. In grassier months our horses do benefit from being fed Magnesium Oxide. Commonly recommended by trimmers, equine podiatrists and other professionals, magnesium is essential for carbohydrate metabolism and capillary wall quality. It is also used as the base ingredient in the majority of commercial calmers.

We supply the “light” finely ground version of Magnesium Oxide from the sole licensed distributor of this product in the UK who can provide a certificate of analysis and a MSDS (material safety data sheet). Unlike the majority of the horse supplements out there this is product is the highest purity human pharmaceutical grade magnesium oxide.

We supply our MagOx in 1kg units which come packed in two convenient 500g bags. To keep the price as low as possible for our customers we don’t use fancy packaging, we do however use high quality human liquid food grade resealable plastic bags, liquid food grade packaging has fewer harmful chemicals than cheaper plastic alternatives.

Although we primarily supply MagOx Light in 1kg and 2kg units we can supply larger quantities i.e. 5kg, 10kg or 20kg bags if you require larger volumes. Please contact us directly for details.
Magnesium Oxide Heavy
While we choose to use and prefer the gentler action and greater absorption benefits of MagOx Light, we appreciate that other horse owners may prefer to use the Heavy version of Magnesium Oxide. For those who prefer to use MagOx Heavy we are able to supply it upon request in the same highest purity human pharmaceutical grade as our MagOx Light so please do get in touch


It is important as horse owners to understand that cheaper versions of magnesium in the market are likely to have high levels of iron contamination this is especially true of magnesium carbonate, if you are in any doubt about the quality of a product you are using be sure to ask the manufacturer for a current product specification.
