Tessa Stewart (Plymouth, GB)
Only calmer that helps my horse

Having tried almost all magnesium calmers on the market, this is the only one that seems to work for my horse. And it’s very palatable. Won’t compete without it 👌🏽

Thank you for your fantastic review Tessa! We're thrilled to hear that our Cool It Paste works for your horse and that they find it palatable. Your satisfaction and your horse's performance mean the world to us. We appreciate your trust in us and look forward to serving you and your horse in the future:) Holly

Chelsea Townley (Manchester, GB)
Only calmer that’s worked!

I’ve used many calmers over the years and seen no/minimal effect, mainly just continued to use to make myself feel better. This calmer has worked on both my mare and young stallion who both get tense when ridden, particularly out at events. Both have shown really rideable attitudes with this calmer and have been able to perform well due to being relaxed. I’ve continued to buy more and now have a stash stored for any occasion! Thank you Equine Products UK Ltd!

Thank you for your glowing review Chelsea! We're thrilled to hear that our Cool It Paste has made a positive difference for your mare and young stallion, helping them stay relaxed and perform their best at events. We're honoured to be your go-to choice for calmers. Your trust means a lot to us:) - Holly

Tegan Harteveld (Lincoln, GB)
Absolutely brilliant

My horse is a very stressy and has become dangerous for the farrier. As a last ditch attempt before full sedation, I tried this calmer. What an absolute change! My horse stood like a pro. Didn't move and just let the farrier work! I could cry! So so happy! All feet done in 15 mins instead of one foot done in 45 mins! Highly recommended

Hi Tegan, hearing this feedback has made our day!

We are absolutely thrilled to hear that Cool It Paste has made such a positive impact on your horse's behaviour during the farrier visits.

It's wonderful to know that our product has helped alleviate your horse's stress and turned a potentially dangerous situation into a calm and cooperative one. We understand how challenging it can be when a horse becomes difficult for the farrier, and we're grateful that you decided to give our calmer a try.

Your success story truly warms our hearts, and we appreciate you recommending our product to others :)

Suzanna Dodd (City of London, GB)
Worked so well

This product was perfect for calming my horse to take her out on her first common riding

Hi Suzanna, we're so happy to hear we were able to help keep your horse nice and calm for her first outing! If you would ever like any advice or assistance please don't hesitate to let us know :) - Holly

Sharon Caldecott (Cannock, GB)
Always Top Quality Products!

I stock up on this cooler every year, ready for "Firework season"& any unexpected stressful situations!
My fussy horse usually eats it hidden in a "sandwich" /mixed into his mash(He doesn't "do" syringes!)& he's far more relaxed about things:-)
I get the tub variety, too, and keep him "topped up" throughout any noisy and busy time,like New Year.
Excellent, quality products that do the job!😊

Hi Sharon! We are so please to hear that we have been able to help your horse stay relaxed during stressful times. It always makes us smile hearing the creativity owners go through to getting their horses to eat things, mixed into mash is definitely a good one!
If you would like any advice or assistance in any way please don't hesitate to reach out! -Holly
