Product Overview

Which horses benefit from calming support?

Supplements in this category 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 in this category 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.

Rated 5 out of 5 by from Worked Wonders Have tried numerous calming supplements for my Arabian but this is first one to truly work. I’m much happier and she is now able to take so many more noises and distractions without freaking out. Like a different horse. Took 30 days to really kick in so be patient!

Rated 1 out of 5 by from Horse won’t eat it I was SO hopeful with this supplement but my gelding will NOT eat it. I tried EVERYTHING!!! He would rather starve that touch this stuff! He wouldn’t even eat around it, one sniff and he would throw his head up and walk away.

Rated 5 out of 5 by from Really works Works quickly, started my anxious & moody mare on this and within a week she calmed down. No more dancing in the cross ties, no more spookiness. Excellent product

Rated 1 out of 5 by from Opposite reaction I switched to this since it seemed to be a better price instead of buying the Mg and B vitamin separately. My horse tends to be a bit reactive, but he's young. After 2 weeks on this supplement, he because extremely spooky and having melt downs over every little thing (stuff that never bothered him before). Switching supplements was the only change. I feel bad as he's so frazzled, and that's not like him. Not even safe to ride right now. Taking him off and going back to the old supplements in hope that he goes back to his normal self!

Rated 5 out of 5 by from It REALLY Works!! I own an off the track Thoroughbred who is VERY spirited and likes to spook at almost everything while on the trail and likes to fight me in the arena. I started this supplement about 2 months ago and unfortunately wasn't able to see if it helped him under saddle until today, due to me being injured at work several weeks ago. He was like a new horse today! I just walked, trotted and cantered a little and he was my horse with his usual spirit but none of his usual hijinks!! I couldn't believe it, he didn't want to gallop straight away when I asked him for a canter! He was such a good boy, for not being ridden for almost a month and a half, no was like I was riding the worlds brokest horse. I was THRILLED. Thank you SpartPak!!!

Rated 5 out of 5 by from Getting back to normal!! Two months ago, Mack, my 19 yr. old Standardbred gelding, moved with us from a quiet, suburban backyard barn in Westchester County, NY to very rural upstate NY. After a couple of okay days, Mack quickly realized that “rural” doesn’t necessarily equate with “peaceful”! There is a freight train track a field away, an interstate a ways beyond that, wonderful neighbors that train hunting dogs and shoot skeet, duck season, now deer hunting season.... It all quickly became too much for Mack. He’d spook at something and then run himself into a lather - over and over. He wouldn’t eat or drink well. He was nervous and out of sorts. Very uncomfortable and unhappy. Which had me just worried sick about him. I thought that I might end up having to re-home him! Luckily, in desperation, I thought of SmartPaks, which we’d used at other times over the years. I ordered SmartCalm Ultra, as well as U-gard Pellets for him, which arrived quickly. What a life saver!!! I could see the results almost immediately! He was SO much better - not on high alert all the time, he could relax and actually lay down to sunbathe! He started eating and drinking well again, and gained back the weight he had lost. I had been worried if he would even eat the supplements because he is quite a picky eater, and he wasn’t eating much at that point anyway, but, thankfully, no problem at all - he would even eat them right out of my hand. So, sorry for this novel-length review, but I continue to be thrilled by how these products helped turned our bad situation around!

Rated 5 out of 5 by from I think it works My mare has been on this supplement for over a month now. I feel like she is more focused and easier to manage. She is still herself, looky and flighty, but easier to bring back into a centered mind. I think this supplement has helped. Also, she does eat it. At first she was suspicious and wouldn't, but she got used to it after about a week and eats it fine. She's not the type to clean her plate, but not suuuper picky like some horses.

Rated 5 out of 5 by from Helps with my horses jumpiness He’s been on it for a few months not as jumpy. Easy to use I think it helps

Rated 5 out of 5 by from Really works! My mare is a totally different animal now. I have been using these pellets for almost a year now, and I started seeing the different within a couple of weeks. I also have switched her over to the Dr Cooks bitless bridle and that has decreased her anxiety level even more. Recommend highly!!

Rated 5 out of 5 by from Calmed my Spook Monster My horse came up to New England from down south - from large pastures and fields to a suburban environment. Right from day one everything here at this busy barn and on the road was scary! And his reaction to everything was to be a super spook ... in hand and undersaddle. I spent weeks trying to get him used to his new world but he was too anxious to break through to. Thinking this will just be what I have to deal with I thought I'd try SmartCalm Ultra - couldn't hurt right? Well - after 8 weeks - it has helped so much! It took a full 8 weeks to take effect with him because he was so over-reactive - he trained himself to spook at everything! Now - he's so different ... he is now allowing himself to relax. There is still an occasional spook - but "normal" ... it took a while for me to retrain myself from expecting him to spook too! This supplement is the real deal! He will always be on it. Now I'm hoping he stays this way when the New England fall winds whip up his tail! LOL

Rated 5 out of 5 by from Give it a month I have a high anxiety mare and at first I thought this did absolutely nothing for her. After about a month of use she is super calm and cool. Not to mention she eats every crumb.

Rated 5 out of 5 by from Supplement change my horse! I have had my horse on this since May after working up and taxing potential gi ulcers and weight loss. My horse went from being a relatively lazy unphased horse for many years to recently being so nervous he was pacing and acting so spooky for the last year. After ruling out any medical issues and changing diet/lifestyle as much as we could my vet recommended Ultracalm to help relax him a bit as we worked on fixing potential other factors. It’s been like night and day now he is so much more relaxed and happy. He’s gaining weight and has stopped pacing. I also noticed he’s been able to sleep more and resting on a regular schedule at the barn. I plan to continue using this supplement long term!

Rated 5 out of 5 by from Works as well as promised! I began rehabbing a 14 year old KWPN gelding who had been abused. After a month on a similar (but more expensive) product from another company, I started him on SmartCalm. Within a week he was less reactive- it has now been nearly two months and he is a far happier boy. All of his PTSD triggers have faded; he is enjoying his work, trusts his rider, and has the quality of life I could only dream of for him. SmartPak, thank you for helping me give him his new start!

Rated 1 out of 5 by from not palatable I can't really say if it works or not, since I couldn't get my mare to eat it. I tried for over a week, and she finally just quit eating her grain. She is a picky eater, but I can usually get her use to it. This is a no-go for her.

Rated 1 out of 5 by from My mare eats just about anything but stopped eating her grain as soon as I started feeding this

Rated 1 out of 5 by from No results I bought this one month ago and had my horse on it the entire month. I did not notice him being any less spooky than he was.
Date published: 2020-06-19
Rated 3 out of 5 by from I’ve had my 6yo OTTB gelding on this for a little over a month now and it seems to be helping somewhat. We were having issues with him being spooky and reactive to pretty much everything and I was frustrated. While I haven’t had much time to ride due to the pandemic, I can’t say for certain how he is under saddle and over fences now, but he seems to be a little less reactive and stressed on the ground/lunging. So far, I wouldn’t say it’s life-changing, but it’s definitely made a slight difference.

Rated 3 out of 5 by from Works amazingly, but horse doesn’t like to eat it I have had my horse on this for several months. It works amazingly well, but she really hates the taste of it. When it’s in her grain she tries her best to pick most of it out, and will SOMETIMES finish it later. Whatever grain is touching it she doesn’t want to eat until her next meal is dumped on top. I will have to switch back to quissence, sadly, because she ate that fine, but after months she still hasn’t adjusted to this one and really doesn’t like the taste, which is a shame because it works better than anything else I’ve tried. It stinks that my horse is being picky about it! If she would eat it, I’d give it 5 stars.

Rated 5 out of 5 by from If your horse is like mine...this stuff WILL work! Without going into a long-winded explanation, I will just say that if your horse is the kind that gets easily wound up, has had an uncharacteristic increase in spooky, reactive behavior, and/or seems to have tightness throughout the back...give this stuff a try. Magnesium deficiency is a real thing, and SmartCalm Ultra has a nice healthy dose of Magnesium that will address it and help a deficient horse be able to relax. The little bit of B-vitamin and tryptophan doesn't hurt either. My guy has been on it for just three weeks, and I'm already seeing major improvements. He's still wide-eyed and wary about certain things, and is very attentive to everything happening around him, but he isn't losing his mind over it like he was just a month ago. He had become unrecognizable to me (I raised him myself and he's 12 years old) this spring, and SmartCalm Ultra is gradually giving me my horse back.

Rated 4 out of 5 by from Great stuff! I think smartpak does a great job with their supplements. My gelding has been acting very spooky these spring months due to stress and after one feeding of this supplement changed his disposition from spooky and nervous to calm and collected. One twist however is that he’s hesitant to eat it, but that’s okay. Thanks smartpak!

Rated 2 out of 5 by from Calming supplements I want to start by saying I love Smartpak! I am trying to solve a spooking problem with my horse by using the ultra calming supplements but I don’t think that is His issue. He was diagnosed with early stage uveitis so I am addressing this now. He may be spooking at shadows. I will be using Smartpak for a hoof supplement because this company is the BEST. Customer support is awesome!

Rated 5 out of 5 by from Very effective after 30 days I started giving this to my 15 year old OTTB gelding who has always been a hot, anxious, and sensitive horse. I had to move him to a boarding facility that unfortunately, didn't have much turnout and I knew this would make his normal tendencies that much worse. After 30 days of being on the supplement, I've seen a big difference. Although he's still the same horse and has the same tendencies, he is not as quick to become agitated and seems more calm overall, especially in his stall. I've seen a little bit of a difference undersaddle, but he still has the same personality of becoming anxious in certain situations. But again, his reactions are not quite as dramatic as they used to be. Overall, I'm very happy with the product and would recommend it to others. I wasn't expecting a miracle cure, just a little something to help minimize his tendencies towards stress and anxiety over little things. And this supplement did the trick! Last note: my guy is hit or miss when it comes to eating new things in his feed. He took to this supplement right away and will eat it even without grain in the bucket!

Rated 4 out of 5 by from Seems to work! My 8 yr old big eyes at everything mare is returning to work after an injury. This supplement seems to help her focus and be smart and calm! She won’t eat it plain - I mix it with sunflower seeds.
