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.

Rated 3 out of 5 by from Unfortunately, we didn’t notice a change with this supplement.

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.

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 5 out of 5 by from Totally Works! My horse has been on this for about a month and I have seen a huge difference in his stress level, he is much less jumpy and on edge.

Rated 5 out of 5 by from Really works! Smart calm ultra has worked wonders for my horse. Just enough to take off the nervous energy and allow him to think and perform better.

Rated 5 out of 5 by from Helped my ottb I started my ottb on smartcalm ultra and noticed a difference within 2 weeks. She was calm and collected and had a brain again!
Date published: 2020-05-28
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.

Rated 5 out of 5 by from Huge difference! My 6yr old Friesian gelding has been on this for 2yrs. He is much more relaxed and focused.

Rated 4 out of 5 by from I have used the paste and was happy with the results. My horse is coming back to work so we will see how it goes.

Rated 5 out of 5 by from Supplement from Heaven ! This works !!!!! Not only did this work on some nasty hot/cold Michigan weather changes , but it honestly helps with my mares cycle . It takes the edge off a cranky mare attitude and stall boredom . This supplement worked on my OTTB gelding too when it gets cold and windy out and the boogyman comes out to get him on the way to his paddock . I will never be without this supplement . It makes for a much more controlled and happy horse which means better attitudes , rides , grooming and monthly cycles . Overall I wish I could give this product a million stars ! It is truly a game changer for my two horses .

Rated 5 out of 5 by from It's working My mare was on Quiessence for about 4 months (did the loading dose and everything). It did absolutely nothing for the spookiness for my chestnut mare. My mares horomones are already being balanced by Regumate. I'm on my first 28 days of this supplement mixed with LegUp Mare pellets and my horse hasn't spooked since the first week. She also eats this easily unlike Quiessence.

Rated 3 out of 5 by from Not sure this does much I have had my 16 yr old OTTB on this supplement for a little over a year now. I have noticed a slight change in his attitude under saddle. He is much calmer to take out for a trail ride by himself and seems more confident. However, he still has anxiety attacks about once a month where he will run back and forth in his ring trying to get out. He also still gets upset when any horse on the property is taken out of his eye sight. Not sure if this supplement is really making a difference.
Date published: 2020-04-16
Rated 2 out of 5 by from I’m not really impressed by it, he has calmed down a little but I was hoping for more, it may work on others if they are not as nervous as mine.
Date published: 2020-04-13
Rated 5 out of 5 by from Great product My gelding has been on Smart Calm Ultra for a little over 3 months now and I have noticed a huge improvement. He is not spooky and jumpy about everything. Little things would put him over the edge and he ignores them now. He could also be an anxious horse under saddle and now it is way less. It has made him more level headed and easier to deal with.
Date published: 2020-04-09
Rated 5 out of 5 by from Fabulous product I began using this product on my horse. Through the past few years she developed severe anxiety. I began using Smart Calm Ultra 8 weeks ago and see great improvement. Still working on underlying causes of her anxiety.

Rated 2 out of 5 by from Still waiting I was hoping this supplement would help calm my 20 yr old arab gelding, but I’m still waiting. Maybe this next month will be the turn around. We’re going on two months now.

Rated 5 out of 5 by from SmartCalm saves lives (and my sanity) SmartCalm Ultra is my dragon-taming secret weapon. The times I've made the mistake of thinking "does this reaaaaally make a difference?" and took my anxious hothead off it, I regretted that decision real fast. My gelding isn't a spooky horse but is very forward and prone to anxiety under saddle and I 100% notice when he's on it vs. not. Lesson learned, for his happiness & mine, he's staying on this for life
Date published: 2020-03-28
Rated 5 out of 5 by from My 20yo thoroughbred gelding has been on Smart Calm for about 3 weeks now. He can be over reactive in some instances and nervous when his schedule is even slightly changed. Since he has been on this supplement I have seen an overall calmness in him. So far so good!
Date published: 2020-03-27
Rated 1 out of 5 by from Adverse effect My mare was only on this for a week and 3 days and turned into a lunatic. Nothing involving her environment nor training has changed except adding this to her daily intake, therefore I could only assume it was the SmartCalm. I was not about to keep her on it for 2 months when she was already like this after being on it for such a short amount of time. It would only be a matter of time before she injured herself, me, or someone handling her.
Date published: 2020-03-26
Rated 5 out of 5 by from It works! I’m so impressed! I’ve only been using this product for a short time and I see a HUGE difference in my horse. I’ve used other supplements with magnesium that didn’t do a thing. I’ve owned this horse for over a year and he’s reactive and borderline dangerous. I was considering selling him because of this. I tried many training methods without success. Once I started the supplement I got the horse I knew he could be! I’m so happy I could almost cry! He’s level headed and a pleasure to work with now. :)
Date published: 2020-03-19
Rated 5 out of 5 by from This works! I bought this product for my horse that has always been a very high-strung, nervous Paso Fino. Within 2 weeks, I saw a little improvement, but within 4 weeks I saw great improvement. Prior to using these pellets, if she spooked (which was often) she would either jump to the side, or spin me around. She has not done that once after using this product for about 3 weeks. Other ladies I ride with have noticed her more calm nature as well. I will continue to use this product.
Date published: 2020-03-18
Rated 4 out of 5 by from Already measured out I bought it and she seems to be doing less pacing when other horses go to back of their pasture and out of sight

Rated 5 out of 5 by from Works! SmartCalm is helping our stall bound horse heal from a broken leg in keeping him calm during his recovery.
Date published: 2020-03-17
Rated 5 out of 5 by from Made a big difference with my dragon...I mean mare I tried just about every calming/ mare-tude supplement out there and this is the only one that made a difference in my mare. She is a very hot horse which caused her to spook A LOT and now that she is on this supplement she puts her energy into positive things like working really hard instead of spooking at her own shadow....or the bush....or that rock....or the horse-eating squirrel. I even took her off of it for a few weeks over the winter to see if she had just improved on her own and no longer needed the supplement and within a few days she was back spooking at everything. So I put her right back on it and she's back to her manageable happy self :)

Rated 5 out of 5 by from Great taste! Tuffy eats it up. I purchased this a month ago to help calm a gelding that I have had for 5 months. He can become very anxious and gets himself all worked up. It has really made a difference in his behavior.
