Product Description
Magnesium is an essential mineral, playing important roles in many areas of metabolism. One of its major roles is as a co-factor in the enzymes involved in nerve and neuro-muscular transmission – helping to regulate nerve to nerve and nerve to muscle transmission and communication.
A lack of magnesium can result in nerve and neuro-muscular excitability, resulting in a tense, nervous horse.
Stressful situations such as strenuous activity and competition, travelling, prolonged stabling and lack of grazing, or new environments may further increase magnesium requirements as stress levels rise.
Magnitude provides supplemental magnesium, together with controlled amounts of calcium (another key mineral in nerve and muscle metabolism), to help promote healthy nerve function and reduce tension, enabling the horse to focus and concentrate.
What are the benefits of Magnitude?
Magnitude provides magnesium from Magnesium Oxide, which is produced from calcined magnesite, extracted from natural deposits in the earth. The Magnesium Oxide used in Magnitude typically contains 52.7% elemental magnesium.
- Natural source of magnesium to supplement low or marginal levels in forage.
- A very small daily serving of 5g provides 2.6g elemental magnesium, easily mixed in feed for fussy feeders
- Safe use with most typical fortified performance and leisure feeds and forage.
Colour Change
*Slight colour change - but the same great product, now with even more quality assurance!
We are pleased to confirm that there is no difference in the magnesium levels, or the chemical source of the magnesium used (magnesium oxide - MgO), only in the physical form of MgO we are now using.
This change in physical form (to the slightly more granular form, with a pale beige colour) has arisen because we are delighted to report that we are now manufacturing Equine America (UK) products in the UK, using certified facilities with the highest standards of safety and production. Although Equine America (UK) products have always been free from prohibited substances, our new UFAS and BETA NOPS certifications will provide further reassurance in the light of recent high profile prohibited substances cases, giving our customers peace of mind regarding FEI, BEF and BHA prohibited substances, enabling full traceability.
In order to comply with the rules and regulations regarding these certifications, we are only able to use certain suppliers, who are also certified, and have had to make a change to our supply of magnesium oxide, so we are now using the lower dust, slightly granular form, which is pale beige.
If you have any queries, please no hesitate to contact the Office.

FAQ
All your questions, answered.

The thermoneutral zone is the temperature range where the body can maintain its core temperature with little to no extra energy expenditure. For humans, this range is quite narrow at 21–28 °C, but for horses it’s much broader at 5–25 °C.
This difference means we should avoid rugging horses based on how cold we feel. Over-rugging can lead to serious health issues, including metabolic problems and thermoregulatory dysfunction.
Tips for Choosing a Winter Rug Weight
-
Clipped horses may need a heavier gram fill to stay comfortable.
-
Remember: horses warm themselves more easily than they cool down under a rug. If unsure, choose a lighter rug.
-
Check your horse regularly to make sure they are neither too hot nor too cold.
-
Consider your horse’s age and natural ability to stay warm.
-
As a general guide, rugging is usually appropriate when temperatures drop below 5–10 °C, but always adjust for your horse’s individual needs.
-
Always ensure rugs are waterproof. A wet rug is worse than no rug at all.
This is an indicative guide only. Always take into account factors such as wind chill, your horse’s age, weight, and condition.
