The Science Behind the Calm

Magnesium is an essential mineral — one that your horse’s body cannot produce on its own. It must be provided through the diet, and modern feeding often falls short, especially during times of lush pasture growth, or when stress, travel, or training increase magnesium demand.

This mineral plays a vital role in:

Muscle function — magnesium allows muscles to relax after contraction (while calcium triggers contraction). A deficiency can result in muscle tightness, twitching, or stiffness.

Nervous system balance — magnesium helps regulate nerve transmission, assisting calm behaviour and mental focus.

Overall comfort and rideability — adequate magnesium supports smooth movement, responsiveness, and the ability to relax both physically and mentally.

Common signs of magnesium deficiency may include:

Over-reactivity or unpredictable behaviour

Difficulty relaxing, even in familiar environments

Sensitivity to grooming, girthiness, or tension through the back

Muscle tremors or tightness (“guitar string” muscles)

Over-sensitivity to sound, movement, or touch

Adding OBT Magnesi-Calm to the diet can assist in rebalancing magnesium levels and supporting a calm, comfortable, rideable horse.

How to Feed

Maintenance: Feed 1 scoop (approx. 15g) daily for 500kg horse.

During periods of lush pasture or heightened stress: Up to 2 scoops (30g) per day
Introduce gradually over 5–7 days.
Mix well into feed. Always ensure access to clean, fresh water.
