Magnesium Oxide, actual purity 99.7% to 99.8% MgO.

Please note the actual percentage of Magnesium Oxide MgO varies between 99.7% and 99.8% depending on the batch number of the product in stock. The actual percentage will be written clearly on the bag.

Magnesium Oxide 99.7% to 99.8% is a high purity ultra low iron pharmaceutical grade magnesium. It is virtually tasteless, making it well accepted in food.
It is a very fine particle size for optimum absorption.

  • Magnesium oxide is the primary ingredient in many of the quality equine calming products on the market.
  • Magnesium is needed for more than 325 enzymes within the horses body.
  • Involved in protein synthesis so needed for general growth and repair of tissue, e.g. Hooves.
    Required for the maintenance of normal blood circulation within the body, limbs and feet of the horse
  • Magnesium is critical for balanced secretion of insulin and glucose uptake.
  • It is involved in supporting correct blood sugar levels after carbohydrate intake and inadequate levels are
    associated with incorrect insulin function  (symptoms include cresty neck and/or fat deposits).
  • Magnesium is essential for proper calcium absorption and is an important mineral in the bone matrix.
    It can also assist in the absorption and metabolism of Vitamins B, C and E.
  • Low levels of Magnesium can result in nervousness and an inability to concentrate, tight tense muscles
    which are less able to relax, tightness or tenderness through the back, slow to warm up.
  • Periods of stress lead to an increased need for magnesium.
  • Magnesium is often lacking in equine diets due to processed, preserved, high concentrated feeds.
  • Magnesium is important for the detoxification of toxic substances from the body. It supports
    against heavy metal toxicity.
  • The availability of magnesium is low in; fast growing lush grass; after periods of rainfall; in
    acid soils i.e. ‘horse sick pastures’ or artificially fertilised pastures (acid conditions destroy soil
    microorganisms which are used to make the minerals usable by plants).
  • Useful when magnesium needs boosting in the diet of horse and ponies prone to laminitis.

    I was looking for a supplement that would help my mare’s mood and her hooves. My mare can be a bit stroppy, so started using this product as an addition to her feed. So far she appears to be a lot calmer and hooves are looking good.

    Progressive Earth is a great company. They are fast to ship, have great customer service and great products that are suitable for my sensitive EMS horse. I love the little chocolate bar you get in your package too! Thank you Progressive Earth 🙂

  18. Wendy

    Excellent quality. Even better service.

  19. Kate B.

    My horse eats this MgO happily and needs less than the previous product I used, so it’s more cost effective as the same weight of product goes much further

    Brilliant for adding magnesium alone to the diet. I did lots of comparison of magnesium supplements before going for this due to the superior composition. Great products from Pro Earth as always!

  30. Maria

    Good quality, taste seems to be a bit of a problem but I guess that can’t be helped, so difficult to get the quantities in that I want, especially with ponies that haven’t got big feeds

  31. Ian B.

    High quality product at a great price

  43. Susanne Britton Hickson

    My barefoot, spooky Warmblood does very well on this, in addition to his Pro mineral mix. At 650kg I only add about half the recommended daily dose to boost the mineral mix. He’s sane and sensible on that and his feet are extremely strong. Well worth the money.
