Product Overview

Supports healthy nervous system function

Quiessence® provides high levels of Magnesium and Chromium in a pelleted form. Quiessence® is a supplement formulated to support normal glucose metabolism, balanced behavior, and relaxation in horses. Equines diets are often low in Magnesium, especially for equines in work, who are kept stalled, or are fed feeds that are processed with preservatives. Supplementing with Magnesium to these horses, support proper nerve and muscle function. Quiessence may be helpful for horses that are overweight and cresty-necked, and may also help with calming.
  • Provides 8 g of magnesium & 1.30 mg of chromium per 2 oz serving
  • In addition to calming, this formula may be helpful for horses that are overweight & cresty-necked

Rated 5 out of 5 by from Helps my nervous mare focus I started my nervous and herdbound OTTB mare on this about two weeks ago now and there has already been so much improvement. She use to be very "fight or flight" when away from her buddies but now she remains calm and actually thinks and responds to me. Still some spook today from a killer bag blowing but she calmed down very quickly after a snort and a quick circle - this is miles away from the horse that would have reared and bolted for the paddock a few weeks ago. I love how this really helps her to think about things and keeps her personality intact without making her "dopey."

Rated 5 out of 5 by from Best Calming Product I just started my moody mare on this supplement January 2022. Although it has only been two weeks I already can see a difference. She has very intense anxiety and we have had her on multiple calming aids since owning her including Veterinary intervention. We have hauled to multiple places for schooling and she is the best version of herself. 100% recommend if you have a difficult mare or a OTTB that is tense.

Rated 5 out of 5 by from Works great! We have a horse that tends to be anxious and occasionally hard to focus. We've tried other supplements with minimal effects. On the advice of our trainer, we gave this a shot, and it's been great! He's not sedated at all but able to be calm and focus more. We will be continuing this supplement for him.

Rated 5 out of 5 by from Muscle relief Clients horse had very stiff, muscle bound shoulders. Correct saddle fit, correct shoeing, body work, ECT...week of Quiessence... Tremendous improvement. Jumping better, moving better, more content. This product was also recommended by one of our veterinarian s. We aren't using it as a calming Supplement, but as therapeutic support. Amazing. Have used it on various horses, for various reasons, for several years

Rated 5 out of 5 by from Great Results! I had my horse on SmartCalm Ultra and it was helping him with his anxious ground manners but ever since i started him on it he was refusing jumps at the shows. Once I switched him to Quiessence he didn’t refuse a single jump at the shows. Is it a coincidence? Not sure but I am still happy with this product! He does seem slightly more anxious than he was on Smartcalm but could also be the change in weather. I am planning on just leaving him on Quiessence from now on.

Rated 2 out of 5 by from My horse has only been on Quiessence less than 60 days. She still gets amped up when she is in the company of other horses especially on trail rides. I am hoping after 90 days she will show substantial improvement.

Rated 5 out of 5 by from Love this supplement I use this on two of my geldings. It has helped them both tremendously. One is much less spooky and the other has gone from being aggressive and pushy to relaxed and a joy to be around.
Date published: 2020-08-18
Rated 4 out of 5 by from Possibly the reason for successful move. Easy to mix in grain and palatable to my picky Andalusian mare. Only problem is it is pricey because you have to administer quite a bit each day.

Rated 1 out of 5 by from Ruined my horses topline I purchased this is a smartpak in February for my chunky navicular pony who needs a high dose of magnesium. It stripped her of ALL of the muscle and fat on her topline, a problem she has never had in all of the three years I’ve known her. She has always had a beautiful topline and now even after being off of it for two months she still has not regained any of her topline. This supplement was the only change that was made, which clearly shows that it was the fault of the supplement. I was so worried I had to have the vet out because she looked so awful and skeletal. This supplement may work for some, but it certainly did not work for my horse. I just hope I am eventually able to get her topline back to where it was and this supplement didn’t do irreversible damage. Definitely can not recommend.

Rated 2 out of 5 by from Didn't work I had my spooky, oversensitive horse on this supplement for about 4 months and noticed no difference. I opted for SmartCalm ultra which is around the same price and I already notice a difference in less than 20 days! My horse whose not a super picky eater, but definitely doesn't just eat anything did not eat this without a fight. I had to mix it in well with her grain and soaked alfalfa.

Rated 5 out of 5 by from Hopefully will give him some calming help I am looking for additional calming and focus on my Boy. We are giving it to him now!

Rated 5 out of 5 by from After 3 months... I tried this on 2 horses, had them on it for about 3 months now one of them when in stall would head bob like crazy and just be very hyped up all the time, he would also be very mean to other horses in groups bullying them! Now after about 3 months he is a lot calmer less head bobbing almost stopped! And more mellow with other horses now, now I catch him grooming buddies instead of attacking them! Aha For the other one on it I was using it more for helping her get her weight under control along with a diet plan and stuff and so far haven’t seen any difference in that but for calming this stuff definitely works! Only thing is it is very expensive!

Rated 3 out of 5 by from Going on 3 months now... This will be my 3rd month on the double dose for my mare and gelding and still zero changes in fat pockets And weight (with cut hay back) and zero changes in moods gelding is still head bobbing when stressed in stall and bratty to handle still everyone is exactly the same as before started :/ really hoping this stuff starts working..

Rated 4 out of 5 by from This worked really well for my horse. He's calmed down quite a bit

Rated 3 out of 5 by from So far no changes just more urinating?! I bought this for my mare and welsh pony. They both are not obese but on fat side! I started them both on the double dose like says to do,(says to give double dose till see changes than cut back dose) so the mare is at 4 scoops and the welsh pony is at 2 scoops. I also cut both there hay back and both on exercise plans. The welsh pony is very much a bully to all horses! He is also fresh to anyone handling him and when bored or stressed he will stand and head bob in his stall or outside waiting to be turned in or if just stressed, so I was hoping this would also help him calm down and relax! so far I have had them both on this for almost 1 month now and have seen no difference at all I either unfortunately, only thing is my mare is urinating a lot more than normal. Smartpak says supplements take 2-3 months to start working so I am going to give another month and if still no change they will be taken off this supplement because it is definitely not cheap!

Rated 4 out of 5 by from Will cause excessive urination My picky horse is willing to eat this in his food. This supplement is one of the highest sources of magnesium available. My horse is on stall rest after an injury, so his muscles are sore from not moving. I think the magnesium is helping his sore muscles. However, the prescribed dose of two scoops a day made my horse urinate excessively. I cut it back to one scoop a day and that works better. Excessive urination can lead to an electrolyte imbalance. I can't speak to whether it helps calm him or not because he is currently also taking Trazodone to keep him calm. Once I can taper him off of the Trazodone I will keep him on the Quiessence and see how it goes.

Rated 5 out of 5 by from Great for EMS horses My pony has been on this for a couple of years now. She came to us extremely obese (body score of 9) with out of control EMS. I spoke with a nutritionist and we decided she needed a high dose of magnesium to help control her metabolism. I began to notice a reduction in her fat pockets after about a month. Fastforward to now- she has no fat pockets, her crest is completely gone, and she is healthy, not to mention the change it has made in her attitude! She was always very ornery for about the first 8 months of me owning her, I attributed it to the fact that she probably felt like poo due to her EMS. I do believe that this has helped a bit though with that as well.

Rated 5 out of 5 by from Fantastic Product that Works! I have had my gelding on this for almost two months now and I have seen a tremendous difference in his attitude. Sometimes I am the only one out riding and he would get tense and nervous and no fun for either of us. His work ethic has drastically improved on Quiessence and he seems happy to work by himself. His behavior overall is calmer as well. I am very pleased with this product and have already recommended it to my friends.

Rated 5 out of 5 by from Not just for calming - great for big bellies! Bought this for the calming benefits of magnesium, and it definitely helps my guy with his focus and calmness. But what I didn't see coming - is that it has reduced his belly! He's not over-weight, but he's an easy keeper. He has a nice beefy neck (he's a WB/TB cross) - not cresty, but I think he has that tendency. He's always had what the guys at the barn call a "cow belly". I have noticed over the last several months that the belly is gone. Took a while to figure out why. Work load is the same. If anything, I've added calories by giving him a flake of alfalfa in addition to his coastal hay. I did also start using Purina Outlast for ulcer prevention/treatment too - so that could also possibly help. But his weight is awesome right now, and the cow belly is gone! All around awesome supplement.

Rated 5 out of 5 by from Definitely works! Twice I tried stopping it thinking maybe it was just another supplement that maybe wasn’t can do! My pony behaved badly without it for sure—wouldn’t ride him without it!

Rated 5 out of 5 by from OMG This really works I really didn’t have much hope that this supplement would make a difference in my anxious, stressed, fretful mare. Background unknown. But I was pretty desperate. She was starting to settle in but still had a nervous edge. After a week on Q she started to relax and was much easier to work with. It is now pleasure to spend time with a relaxed focused horse.
