Magnesium Horse Supplement

A magnesium supplement provides additional dietary magnesium - a mineral that supports muscle function, nerve transmission and a calm temperament. Many stressed or excitable horses are functionally magnesium-deficient, and supplementation can support more relaxed work and better recovery.

Common reasons: nervous or excitable horses, horses prone to muscle tension or tying up, horses that don't relax in their work, or horses on hay-only diets where magnesium intake may be low. Magnesium-based supplements are often used as everyday calmers (TRM Good As Gold & Magnesium, Plusvital Chillax).

Yes. Magnesium is a mineral and is allowed in all FEI disciplines. Always check the specific product label - some magnesium products combine the mineral with other ingredients that may have restrictions.

Most magnesium supplements need 2-4 weeks of consistent feeding to build up to noticeable effect. Some horses respond faster, particularly if they were significantly deficient. For event-day calming, a magnesium-paste calmer works in 30-60 minutes.

Yes - magnesium pairs with most other supplements. Check the total daily magnesium across multiple products to avoid over-supplementation; loose droppings can indicate too much.
