For a laid-back approach to life. Designed to be fed to horses and ponies with anxious temperaments or those that cannot cope with stressful situations such as showing, travelling and competing.

Not all horses are anxious for the same reason so TopSpec Calmer has been developed with much more than a ‘single ingredient’ approach. It contains yeast, MOS, B vitamins, magnesium, tryptophan and sepiolite clay, which all act in different ways to help calm and relax responsive horses.

TopSpec Calmer reduces anxiety without affecting normal behaviour or reducing presence. It can improve performance by improving focus and reducing the effects of stress. TopSpec Calmer will start to take effect within hours but maximum effects will be seen within three weeks.

TopSpec Calmer contains only natural ingredients but no herbs. It is a very palatable, caramel flavoured additive that should be mixed into damp feed. It can be added to any combination of feeds and supplements, TopSpec nutritionists recommend that these are low in sugar and starch.

TopSpec Calmer is supplied in 3kg tubs which will last a 500kg horse for one month; or 9kg or 20kg tubs which offer a 25% or 40% saving respectively over the small tubs.

Nutritional additives per kg: Tryptophan 20,000mg, Thiamine (vitamin B1) 1,000mg, Niacin 3,000mg, Pyridoxine (vitamin B6) 1,000mg.

Technological additive per kg: Sepiolite clay E563 250g.

Zootechnical additive: Saccharomyces cerevisiae MUCL39885 EU Reg. No: E1710 (Vistacell) to give 1,250 Billion CFU’s per kg.

Composition: Wheatfeed, Salt, Mannan Oligosaccharides (Saf-Mannan) to give 30,000mg per kg, Magnesium (from magnesium sulphate) 20,000mg/kg, Calcium 4%, Phosphorus 0.4%, Sodium 1%.

It works for my sports horse. He’s sharp and gets very tense when doing/going anywhere new. This stuff takes the edge off for him which makes for a successful time out and about.

55 Nicely surprised
Verified Purchase

By on 8 March 2021

I bought this without much hope of it working but thought I'd give it a try. I have a very scary 6 year old mare who is scared of her own shadow. Well, after a couple of weeks there has been a marked improvement....yes, she's still spooky but certainly nothing compared to before. Will definitely be buying more

my horse has had laminitis in the past will this supplement be ok for him and not effect the laminitis.

  • VioVet Staff


Calmer supplements such as this should have no adverse effects on laminitics and Magnesium, one of the active ingredients could even have beneficial effects on combating inflammation.

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.

  • VioVet Staff


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

  • VioVet Staff

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?

  • VioVet Staff

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

  • VioVet Staff

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?

  • VioVet Staff

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.
