Magnesium oxide.

Magnesium has many roles within the body including the health of nerve endings and fibres, and reduction of magnesium in the diet may show in a horse as tension or nervousness. Equine America Magnitude is a highly-absorbable form of magnesium that should be fed daily to horses or ponies to promote healthy nerve tissue and aid the body's natural responses to nervous tension.

For very young, excitable or overzealous horses, requiring focus, increased concentration and calming, a product from the So-Kalm Plus Range will be more suitable.

So-Kalm Plus Paste may also be used as a pre-competition addition alongside Magnitude.

Why should you feed Magnitude?

  • To support the body's natural responses to excitability, nervousness, anxiety or tension
  • To increase levels of magnesium in the diet
How does Magnitude work?
Magnesium is involved in many essential processes within the body and is an important mineral in general health. It is also integral in achieving correct nerve and muscle function. If magnesium is deficient in the diet the horse can appear nervous, tense or anxious. Magnitude can also be used in combination with So-Kalm Paste at shows or events.


For an average 500 kg horse, feed 5 g daily with the horse’s regular feed. Repeat as required or as advised by a veterinary surgeon. Feed others according to body weight, less for ponies and smaller horses and more for larger breeds.

Available in:
  • 908 g (6 month supply at maintenance)
