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 1702.
Rated 5 out of 5 by from Smartpak Tranquility and Ultra Calm together! My 13 yo MFT mare has always been over reactive and anxious and started to be anxious on the trail and being unblanketed. I initially tried Smartpak Tranquility but found that after a month it only took the edge off. I saw a Q&A that I could use Smartpak Tranquility and Smartpak Ultra Calm together and after 56 days, my mare is a totally different horse! She is now very relaxed and calm on the trail even when other horses are reactive and is very calm when being unblanketed. Friends have told me how much calmer she has been and I think Smartpak Tranquility and Ultra Calm made all the difference!

Rated 5 out of 5 by from Wonderful supplement for Head Shaking Syndrome This supplement changed my head shakers life. He was able to go without a nose cover during the day in the SUMMER! It got too expensive so I switched him off it for awhile, but I’m putting him back on it now. It improved his skin sensitivity a lot and helped with his slight nervousness as well, although the main reason he’s on it is for his head shaking syndrome. The amount of magnesium in this supplement would cost a fortune to match with most others.

Rated 3 out of 5 by from No difference I’m not sure this has helped my horse but I do like the packaging and he definitely likes them.

Rated 1 out of 5 by from Caused the Opposite Effect For My Horse This is the first ever SmartPak supplement that did not work for my horse. I have a 17yo Saddlebred who has had mild-to-moderate spooking during his rides all his life. After consulting with a vet and determining the problem wasn't physical, I decided to try this supplement. Unfortunately these pellets achieved the opposite effect and made my typically-safe horse nearly unrideable. After about a week of this supplement, what started out as slightly annoying spooking/"looking" turned into outright bolting and higher baseline nervousness. After discontinuing the supplement for a week, my horse returned to normal. I'm disappointed because this is my first "bad" experience with SmartPak supplements.

Rated 2 out of 5 by from Very bitter taste, horse doesn't like it. I started my gelding on it about 3 weeks ago. He doesn't like the taste but will nibble at it some throughout the day. Often some still in his feeder next morning. Not sure it's going to work out. Not noticing any calmness yet but will continue for a couple months to finish this bag before revising final review. If I see results and he keeps eating it, rating will go up. If he just stops eating it all together or I see no results after a couple more months it'll be 1 star. I don't know why it can't taste better. Lot of horses don't like a bitter taste. Make it a little sweeter and it would be fine.

Rated 4 out of 5 by from Lots of Improvement! We changed several things around the time I started feeding SmartCalm so I can’t give the supplement all the credit. But I will say my boy is a lot less anxious and has given up many of his nervous behaviors, like biting. No plans to take him off these pellets and test him - I’m extremely pleased with his improved attitude.

Rated 1 out of 5 by from Horse won’t eat it I have a picky horse. He wont eat it or anything in his bowl if the supplement is mixed with the grain.

Rated 5 out of 5 by from Works Well! Started my anxious old gelding on Smart Calm a month ago and the change in him is so wonderful to see. Highly recommend!

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.
