Calming Supplement for Anxious and Nervous Horses

Trying to get a nervous, spooky or stressed out horse to stay calm during competition or training is tough, but Kohnke’s Own Mag-E can help! Mag-E is an effective supplement to help ensure horses remain calm and focused during training and competition. 

 Mag-E can be given daily for relaxed, steady behaviour or supplemented a few days before and during an event to take the edge off, allowing your horse to relax and focus without reducing performance.

 Mag-E contains multiple calming nutrients to help horses to focus more effectively and it does not swab, making it legal for competition.  Mag-E has an innovative formulation which includes synergistic calming nutrients which work together to normalise nerve and muscle function.  


Each level scoopful of Mag-E provides 15 grams. 

The normal supplementation rate is 15 grams for horses (400 – 600 kg body weight). For ponies (less than 400 kg) give 10 grams and horses larger than 600 kg can be given up to 30 grams daily.  

Mag-E is normally given initially as a loading amount of 30 – 45 grams per day for horses for the first 5-7 days, before reducing to the normal maintenance rate. 

Mag-E can be used daily, on a long-term basis of 15 grams in the feed for horses which are naturally more nervy or stressed types. 

Mag-E is also suitable for horses which need help during competitions or busy shows, if unfocused or fidgety in stressful surroundings.  Mag-E can be used as a double dose (30 grams) in the feed, or even mixed as a long-lasting paste (30 – 45 grams of Mag-E with 20 ml water and 20 ml vegetable oil).  Give 4 hours before competition or situations where relaxed, calm performance is paramount.


  • Magnesium, with the majority as a protein-coated, organic chelated form for optimum digestive absorption and utilisation in nerve and muscle cells.
  • High potency vitamin E for optimum nerve and muscle function
  • Vitamin B1 (thiamine) for extra calming action
  • Base of stomach soothing yeasts and other natural, synergistic nutrients.

Powdered supplement with sticky consistency and vanilla flavour for excellent palatability and easy feeding.
