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.

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.

Note that our magnesium for horses tends to be priced higher than other sources due to the fact that we and other horse owners only buy the very best product with a very low iron content.

We do not stock a number of magnesium oxide products because your horse’s health is too important. Both the magnesium oxide which we sell separately and that which we use in our balancers are of human, pharmaceutical grade.

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 Balancer or carrying out analysis of forage is wise.

Find out why ratios of minerals fed are so important at Forageplus Talk.

Find out why we recommend feeding our low-iron magnesium rather than magnesium chloride.

    Excellent product. Very palatable. Backed by the excellent Forageplus research and knowledge.

    What a massive difference this has made to my horse. It allows him to lead a much more normal life and be able to go out on the grass.
    He is treated with just herbs, no medication is needed at present.
    100% recommend this product.

  3. Becky Jones (verified owner)

    Amazing product my EMS horse can have a much more normal life thanks to this and can actually eat grass and be out like he used to. 100% recommend if your horse has Metabolic issues this is a must to add to their diet

  4. srmcnally98 (verified owner)

    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!

  5. Kara McKee (verified owner)

    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!

  6. Rosemary Ball (verified owner)

    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!!

  8. Joanmo (verified owner)

    Superb minerals really notice the difference in my Mares after 2 months of specific mineral balance. Great coat, immune system and really in great form.10 out of 10 for support and delivery.

  9. ellerkincato (verified owner)

    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.

  10. 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.

  11. Becky Jones (verified owner)

    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.
