Forageplus Ultra-Pure Magnesium Oxide for Horses. Our premium magnesium oxide boasts an exceptional purity of 99.8%, delivering 60.7% elemental magnesium in an ultra-low iron form.
Essential for maintaining healthy hooves and supporting overall metabolism, magnesium also plays a key role in promoting calm behaviour in horses.
Magnesium is an essential mineral for the health and well-being of horses, supporting nerve and muscle function, hoof health, and preventing conditions like laminitis. Choose Forageplus to ensure the highest quality magnesium oxide for your horse’s magnesium needs.
The iron content of this product based on the certificate analysis is 26ppm (0.0026%) this is twenty times lower than the carbonate form which is typically 500ppm (0.05%), this is why we do not stock magnesium carbonate.
Magnesium plays a crucial role in the health and well-being of horses, being involved in various metabolic processes essential for horse survival and health. The importance of magnesium in equine diets cannot be overstated, as it is often overlooked or deficient, especially in relation to calcium levels which can interfere with absorption.
Learn about how to tell if the magnesium you are buying is of high purity and low in iron here.
We do not stock magnesium chloride because it is less palatable and you would have to feed 5 times more chloride than oxide to get the same elemental magnesium supplementation.
Please note that our Ultra-Pure Magnesium Oxide for Horses is priced higher than other sources because we, along with discerning horse owners, prioritise the very best quality with ultra-low iron content.
We carefully select only the finest magnesium oxide products, as your horse’s health is our top priority. The magnesium oxide we sell separately and use in our balancers is of human pharmaceutical grade, ensuring the utmost safety and efficacy for your horse.
A Magnesium for Horses which is pure and ultra-low in iron
Cheaper products on the market are likely to have high iron contamination, make sure you ask for a current specification to find out iron levels.
Forageplus pure, low iron, 99.8%, magnesium oxide for horses provides 60.7% elemental magnesium.
The iron content of this product based on the certificate analysis is 26ppm (0.0026%) this is twenty times lower than the carbonate form which is typically 500ppm (0.05%), this is why we do not stock magnesium carbonate.
This product is useful to boost magnesium in the diets of all horses and is of potential benefit in the following scenarios:
- Where a forage analysis shows extra magnesium is needed in addition to that contained in a mineral balancer.
- Where horses are showing behaviour typical of a magnesium deficiency.
- Where magnesium needs boosting in the diet of a horse prone to laminitis.
Free from any prohibited substances as defined under Jockey Club and FEI rules.
Forageplus does not advise the feeding of separate minerals unless levels have been checked by carrying out a forage analysis. The ratios of minerals are important and feeding one mineral without supplementing correct levels of another can be detrimental to horse health. If you are uncertain of mineral levels then feeding either a Forageplus Equine Balanceror carrying out analysis of forage is wise.

Probably the best Mg Ox product on the market – especially due to the low iron content. I feed speedibeet as a carrier which I am led to believe is realtively high in iron, so I like to know I’m not adding more in yet again!

My pregnant mare does really well on this supplement. Reassuring to know it is low in iron. Palatable, all of the forage plus products seem palatable as I have a fussy mare and she eats it all!

I bought this for my two metabolic companions but added it to my riding horse’s feed too. My rides are so much calmer now!
Win, win!!

Like all FP products, the low iron magnesium is excellent quality and easy to order. All orders delivered in superquick time. My horses all look great on thoughtful nutrition.
Kelly Elliott (verified owner) –
This is a great supplement for the hotter horses as it keeps them more laid back at home and out at events or arena hires when fed consistently in their feeds you really notice the difference.

Amazing product my horse wouldn’t be here today without him having this in his feed everyday. In the Spring/Summer time and times of high sugar in the grass I increase the amount he has. He is now able to go out hacking in the woods and walks everyday on stoney tracks and he’s barefoot. Helps so much with his EMS

I add this product to my ponies feed, I have experimented with removing it and my horses became fizzy & spooky again. Added it again and within a few weeks much more chilled. Also great for the metabolically challenged horses. Great quality.
