slight improvement in calmness, I have used this over time and believe that you would not see any difference if you wanted to use it for instant results e.g if horse needs calming for vet/ farrier. I put a scoop every day in feed.
I have not noted any side effects as of yet.

What’s the dose for 17.2 warm blood mare, 13 years old please .


  • VioVet Staff

The recommended dose is psated below:

Loading rate - Ponies and medium size horses: 1 - 1.5 measures per day
A level measure weighs approx 25 grams. Always introduce for first very slowly, literally a pinch to start and slowly increase the
amount daily up to the full rate over 10-14 days

A 17.2hh is relatively big so the 1.5 measure will be safe. If you are unsure then try the lower dose first and increase if the expected results are not seen.

My mare can be quite aggressive at times and nappy when being schooled, would this product help her? Thanks

  • VioVet Staff

Equimins is very high in magnesium which is one of the most effective calmer's for horses. However after hearing about your mare I would advise to try Naf Oestress. This is a blend of natural herbs to help mare's that suffer from temperamental or behavioral upsets during there season. The product works by keeping her relaxed but also works by supporting her system against anxiety and muscle tension.

I have my own mare on this product and I wouldn't have her without it. I feel this is the best supplement of its kind on the market, apart from prescription medication.

You could find your mare would need something stronger. There is a product called Regumate, this would need to be prescribed by your vet. This works by stopping the mare's seasons altogether. However under FEI rules you can not compete on this product.

Equimins versus Horse First Relax Me?

Liz Phillips

  • VioVet customer since 2014
  • From: Isle of Wight, United Kingdom

Hi, I have been using Horse First Relax Me on my nervous thoroughbred x warm blood mare all winter with very good results. The remaining problem is her emotional mood; she is very grumpy! She always has been, but this seems to be increasing. I am wondering however, if Equimins (or anything else?) would have the same effect as Relax me and also help her mood? I have tried other supplements such as 'Grumpy Mare' which made no difference!

Thank you

This is a situation where you have to try different products and see what works for your horse. Most people find that some products seem to work while others make no difference. This is unpredictable and it is not possible to know for certain what will work. It is OK to try products out but it is always worth doing all you can to help with the way you handle the horse too. This can gradually yield results too.

Nervous horse

Does Magnesium supplement have the same effect as Calmex do u know please? I am looking for a cheaper alternative, as our mare needs to stay on something, due to cattle issue!

Many thanks,

Horses seem to vary as to how well they respond to all of these products. The only way to really find out how one works with your horse is to try it out. Probably they all can work in the right circumstances, though generally with these things (like everything else) you get what you pay for.
