Product Overview

Which horses benefit from calming support?

Supplements that aid in calming are an ideal starting point for any horse that is excessively nervous, edgy, reactive, unconfident, or spooky. That’s because the vitamins and minerals these products offer help smooth out deficiencies in the diet that can interfere with proper nervous system function.

Additionally, if you compete in rated horse shows, supplements with herb free formulation may be your best option. Unlike herbal calming supplements that often include ingredients that are prohibited by many competitive organizations, nutrient-based supplements generally focus on providing key nutrients like tryptophan, magnesium and B-vitamins that are an important part of your horse’s diet.  Of course, we always recommend checking the rule books for any organizations under which you compete to confirm their individual rules and that these ingredients are appropriate.

SmartCalm® Ultra Pellets is rated 4.3 out of 5 by 1706.
Rated 1 out of 5 by from Complete Opposite affect I started this on my mare to hopefully help her settle with spending more time on trails and exploring outside instead of the arena. She’s now overly excitable, pacing her stall, and a bucking lunatic in the arena where she normally was super level headed. She’s nervous and very jumpy now all the time where before it was just outside on trails. When the supplement was stopped, her behaviour returned to normal. I’m going to switch to the regular Smart Calm as it doesn’t have the tryptophan in it, and I have read that could be an issue. Nothing else has changed accept adding this to her feed. 10/10 do not recommend.

Rated 5 out of 5 by from Always Recommend Smart Calm Ultra First! I have used this supplement on and off for numerous horses and it is always my first recommendation when people mention needing something to just take the edge of. I've always been very pleased with the results as have my friend.

Rated 5 out of 5 by from Love this supplement, notice a definite difference Tried this with my young, green mare and noticed her more focused. Also tried it with my 21 year old, hot and neurotic gelding, and he seemed so much more relaxed and at ease.

Rated 1 out of 5 by from Didn’t Work It did not work at all even though we gave it a double dose. We had high hopes but it was not something that worked for our skittish mare.

Rated 5 out of 5 by from Amazing Supplement My horse was on a different calming supplement and didn’t notice much of a difference. Customer service suggested I try the Smart Calm and he has been amazing. He is more focused yet still his goofy self.

Rated 5 out of 5 by from Gelding stopped cribbing! Unexpectedly, our gelding hasn't been cribbing since going on this supplement. He's cribbed for years, on everything he could get a hold of. But we've noticed in recent week he hasn't been cribbing much or at all since going on this supplement.

Rated 5 out of 5 by from Perfect for a senior horse with anxiety My senior horse started to have vision issues and was no longer mentally comfortable being turned out alone or beyond view of the main herd on the property. It wasn't safe for him to be out with the main herd so it was find a calming supplement/med or nothing. He exhibited symptoms of constant pacing, both trotting and walking, constant calling, and so on. He was too anxious to eat. On recommendation of the vet I looked for a calming supplement and this one ticked the boxes on the list the vet gave me. Within the first few days of being on the supplement he was back to himself and much, much calmer and happier. It provided a crucial quality of life improvement.

Rated 5 out of 5 by from Makes the Edge Manageable I give my horse SmartCalm Ultra paste at horse shows &, while it helped immensely, my horse was still very tense at shows & spooky at home. After a particularly tense horse show at the end of January, I came home & bought the pellets. Ironically, she seemed even spookier the first week I had her on the daily pellets. We just went to a horse show at the end of March, about 2 months later, & she was the most ridable she had ever been, with the daily pellet & the paste just for the 3 days of the show. I had been thinking of taking her off the daily pellet over the summer when I'm not showing, but my trainer made a comment on what would have otherwise been a 'spooky' day at home that my horse was much braver, so maybe I should just keep her on it!

Rated 5 out of 5 by from My go to for cranky Mare!! I have used Smart Calm Ultra for years off and on. My absolute go to when I need her to get refocused. Flush everything else you’ve tried down the drain if you own a unfocused TB Mare !!!

Rated 5 out of 5 by from It works Long story short - my horse had a bad reaction to a medication and then had a pasture accident that landed him in stall rest for 8 months. This horse is a senior and was purchased for his calm nature, but never seemed quite settled after the medication change, and it got worse with the stall rest. I assumed that the "banned" herbs were banned because they were too effective, so I was using a supplement with valerian. Poor guy was mostly fine with me, but wouldn't let my trainer close and would be spooky in his stall randomly. I'm not sure why I switched to this, but in the past 6 months as he has gone off the other and onto this one, he is back to his old self. People can pet my horse again. He isn't tense in the "scary end" of the arena. He is less of a weirdo in his stall and we see a lot less of the whites of his eyes.

Rated 1 out of 5 by from Horse would not eat it My horse eats anything, but would not eat this supplement. Tried adding beet pulp. He would not eat this. Did not want to add anything with sugar as he is on a diet.

Rated 5 out of 5 by from Works well I started my OTTB on SmartCalm Ultra a few months ago. He’s much calmer and less reactive. Don’t expect your horse to act sedated or have a complete 180 change in behavior - this supplement doesn’t do that. What it does do, though, is keep my horse more relaxed and focused. When he does spook it’s not as big of a deal as it used to be.

Rated 5 out of 5 by from Helped my horse After 6 weeks of lameness over my horse's New Year's Even freak out, I wanted to try this over 4th of July. SmartCalm Ultra Pellets was the only thing I changed and he survived July 4th without any injury!

Rated 3 out of 5 by from I've been using this product for a little over a month now and I haven't seen a huge change yet. I think next season I'm going to try a different product. My horse will eat just about anything but he turns his nose up when I feed him this.

Rated 5 out of 5 by from Great product I bought this a month ago and it has worked wonders on my OTTB! He is much more at ease during training sessions so much so that he will take a nap while tied up now! Great supplement to take the edge off!

Rated 5 out of 5 by from Seems to make a difference! I use this for my 25 yr old appendix QH who already runs hot, but lately seems senile and LOCO. After one month this seemed to take the edge off and two months later he is legit quiet and calm. Love it!

Rated 1 out of 5 by from Beware L-Tryptophan Had my horse on this about 3 weeks and noticed he was getting increasingly excitable - unfortunately I didn’t put it together that it could be the supplement until the one day he completely came apart. I’d remembered some posts about L-Tryptophan making some horses very hot and immediate took him off it, and put him back on straight magnesium. He’s back to normal now, where he will look and occasionally have a small spook but nothing near the way he became completely unglued on this supplement. I don’t think L-Tryptophan is a good idea for every horse. Definitely research before buying this and take them off if they start getting worse.
