A highly palatable additive, TopSpec Calmer is caramel flavoured and should be blended with damp feed. It can be added to any combination of feeds and supplements.

Below are some recent questions we've received regarding TopSpec Calmers for Horses, including answers from our team.

Miss Vivien Bastick

Took my horse hunting and he completly freaked out lunging and spinning round and really throw his toys out of the pram. Can you recomend a calmer for this please.

  • Veterinary Advisor


You can definitely try one of the magnesium based calmers, such as Top Spec Calmer. This can take the edge of and reduce the type of behaviour you describe. It's effect varies between individuals so there is no guarantee it will be strong enough, especially given a high "excitement" activity such as hunting. To give it the maximum chance of working it should be given for ar least 5 days prior to the day you intend to go out. If not effective enough there is a product called Zylkene which packs a bit more punch which should be given 2 days before and on the day. If you have no success with these type of products then you are in the realms of prescription medications such as a low dose of ACP. It is also likely that the more times you go hunting the less the requirement for calming medications as you horse will get used to it. Hope this helps.

Sugar content?

Catherine Campbell

  • VioVet customer since 2013
  • From: Staffordshire, United Kingdom

Does this product contain any sugars in any form as my horse is prone to laminitis

  • Veterinary Advisor

This calmer along with most others will contain a small amount of sugar to make them more palatable. Most things your horse eats will contain a small amount of sugar- grass, hay, chaff even if they are soaked or low calorie versions. Given the small quantity of calmer intended to be fed daily it is unlikely to cause much of a problem for your horse though of course I cannot say this with 100% certainty.

How long does a pot last

Sarah Morrish

I have a 14.2h gypsy cob. How long would a tub of this last?

  • Veterinary Advisor

It depends on the weight of your horse. If she is chunky then she may be nearly 400-500kg. In that case a 3kg tub will last 30 days.

How long to take effect

Alexandra Horrocks

  • VioVet customer since 2017
  • From: Greater Manchester, United Kingdom

How long does it take for the calmer to take effect i.e. a week or two weeks etc? Thanks

  • Veterinary Advisor

The calmer should be reaching maximum effect after 5-7 days. Calmers seem to work better for some horses than others so the effect you see will be dependent upon your individual horse.

Percentage of magnesium

Louise Hunter

  • VioVet customer since 2016
  • From: Cheshire, United Kingdom

What percentage of magnesium is in this product? And in what form, i.e. magnesium oxide, magnesium chloride? And does it blend easily?

  • Veterinary Advisor

It is magnesium sulphate in the Top Spec Calmer at 20,000µg per kg. It does blend easily. It is best to mix it with damp feed so that it sticks to the feed and there is no wastage.
