    Ex Stress is rated 4.2 out of 5 by 74.
    Rated 3 out of 5 by from Won't eat it. :( I bought enough Ex Stress powder in SmartPaks for show season. Just found out at our first show of the year that he won't eat it. He went completely off his grain (which he hasn't done before) and the only change had been the addition of Ex Stress. Ex Stress ended up causing me stress! I still gave it 3* because our trainer swears by it (if they'll eat it!)

    Rated 5 out of 5 by from Split between two horses I was interested in supplementing my mare with magnesium as she is on long-term omeperazole for ulcers and studies in humans have shown a decrease in magnesium. When comparing supplements I noticed Ex-Stress had significantly more B vitamins as most of the other supplements and I know B vitamins can help with spookiness, so I had SmartPack split the dose into two and give half to my sometimes spooky gelding. Both horses are doing great on 1/2 dose!

    Rated 4 out of 5 by from Definitely works I have an OTTB with severe anxiety. The ExStress is definitely working for him. The biggest drawback is that it has to be given twice a day. I tried doubling it up and giving it once a day but it didn't work for my guy. And he eats absolutely anything so I can't speak as to the palatability of it, but the smell is a little off putting.

    Rated 2 out of 5 by from Ex Stress.... I guess I will never know if ExStress works for my horse because he just won't eat it. He's not a picky eater, he used to lick Probios powder off the bottom of his bucket, but he leaves ExStress at the bottom of his bucket with some grain which he never does. The supplement smells strongly of vitamin B so I can't blame him for not liking the taste either. It also stains your bucket, your horse, and your hands. The pellet version is so much more expensive than the powder that I think I will just go with something else all together. I don't want to pay that much more for something that I'm not sure is palatable or will even work!

    Rated 5 out of 5 by from Love It Great product. Only downside is the strong B vitamin smell. Tried smartcalm but prefer this product - less nervous but not too quiet for upper level dressage work.

    Rated 5 out of 5 by from Relieves stress of horse & rider ExStress is a great way to calm the spooky or eager horse without drugging them or worrying about herb balance. We use it on windy days or when the horses are really fresh. Works exceptionally well at new venues when there is so much to see to distract from focusing in competition. Easy directions and effective.

    Rated 3 out of 5 by from My horse wouldn't eat it. I purchased Ex Stress in my Smart Pak. It was a waste of money since my horse wouldn't touch it. I had it mixed with his Strategy Pellets, but he refused to eat. Wouldn't touch it. As soon as I omitted the Ex Stress, he went back to eatting his other supplements. I used the powder.

    Rated 1 out of 5 by from Horse Wouldn't Eat It. I decided to change my horses calming supplement from SmartCalm to Ex-Stress because I felt that the higher level of Vitamin B-1 potency would be a benefit. The first day I fed Ex-Stress (powder) to my horse, he wouldn't eat it. I mix all his supplements with a small amount of STRATEGY and he usually devours it, but not this time. He wouldn't finish it. I will go back to the Smart Calm with an additional Vitamin B-1 supplement.

    Rated 5 out of 5 by from Worth the price My 16 year old Arab-Saddlebred cross is very jumpy when it comes to thunder storms and gunfire. Keeping her on this product is essential for my peace of mind and hers. She still has to be managed through the episodes but is not nearly as stressed as she was without the product. Previously she would colic. stomp her feet and had loose stools, and took up to a half hour to calm down, and I had to give her Pepto Bismo. She is about 75% better with the calming influence of Ex Stress with the B-vitamins for her nerves. Her recovery time is just a few minutes.

    Rated 5 out of 5 by from No Stress with EXStress! Been using this product for over 5 years and can't recommend it enough. Definitely has reduced the anxiety in my mare without a tranquilizing effect. Ingredients are water soluable so there's no worry about toxicity or accumulation. Saw results within 14 days and now she is on a maintenance dosage.

    Rated 5 out of 5 by from A NEW mule! I didn't realize how awesome this product was until my mule was NOT on it for 2-3 months! On this product, he is calm, focused, has manners, collects in the ring, etc. OFF this product, he's a terror to deal with! Anxious, pacing, screaming (mules can't whiney), throwing his head up, pawing, mismannerful, etc. Both the farrier and the vet said, PLEASE, put this mule back on his Ex Stress!

    Rated 3 out of 5 by from Not Sold on This Product My mare does not seem to like the taste of this product and has been leaving her pelleted food, especially where the supplement is. Once senior (sweeter) feed was added to her diet, she ate it more readily. She has only eaten it more consistently for about a week. Given the difficulty in having her eat it (vs SmartCalm, which she liked), I'm not sure if the product has been given a fair test yet. I'm not sure if her increased reactivity since switching is due to not getting the correct dosage of the product for enough time yet OR if the product just isn't as calming as SmartCalm. I just am not enjoying riding my more distracted, nervous Thoroughbred mare as much as I was when she was on SmartCalm consistently...she still had tons of energy but was more focused and less jittery.

    Rated 5 out of 5 by from This works! I have been using Ex-Stress for about a year now. I have tried other calming products, but for my horse, Ex-Stress works the best! I have an AQHA gelding that was very spooky when I got much so that it was very difficult to get his attention He was more concerned with where the boogie man was going to jump out from. After a few weeks on Ex-Stress I noticed a huge difference. He was much more relaxed and I had his attention. This allowed me to start our work on desensitizing and he is an amazing horse now. I take him everywhere! The Ex-Stress does take a few days for them to start eating, but they will in grain. I LOVE this product!

    Rated 4 out of 5 by from Excellent ingredients I first found this product at the World Cup. They sold me when they said no added sugar. Now I get to have a great product in an easy to use smartpak! My older horse is very hot, and is easily spooked even in his own pen. This has certainly taken the edge off.

    Rated 5 out of 5 by from Ex-stress REALLY works This is the ONLY product I have found that works on my off the track TB. She's 17 years old now (still thinks she's about 4) and is on a maintenance dose of ex-stress. It really works. I ran out of the product once and I could barely even walk her to the pasture. I have her on an auto shipment and never again will I go without this product. I like that it's natural and take the edge off without making them drowsy. Before I found ex-stress I never would have thought I'd ever be able to take my horse to a show. Now she goes and shows off her stuff without panic.
    Date published: 2010-09-07
    Rated 5 out of 5 by from It works This is the only calming product that has worked for me. Herbs made my horse jumpy, and other vitamin B or magnesium or combo supplements did not have the same evening out but not dopey effect as this product. My picky eater (herbs are poison!) will eat it. Doses can be upped or lowered depending on the horse. Bought a 5 lb bucket and will use it daily on one horse. The others might get some in stressful situations. Downside: it is expensive relative to other vit B / magnesium products.

    Rated 4 out of 5 by from Actually Stood for the Farrier! We have an ulcer-laden, previously abused, stress case in our barn. A friend with a similar personality & ulcer suffering horse tried this product and swears by it. She brought me some to try. We saw a change almost immediately. He's still a little irritable, but overall much more calm. Even stood quite well for the farrier (his worst anxiety). It's only been a few weeks, so I'm hoping for continued improvement.

    Rated 3 out of 5 by from Okay Purchase My 6 year old gelding has trouble with focus. He's not bad, he's just what you'd call A.D.H.D. I thought I would try the product just to take away the need to stare at a tree for five minutes before gaining our focus back. So far, I feel no difference in his focus or attitude. In fact, after the first week he was on the product he felt more "up" than usual and there was a bit more fighting over what we were going to do that day....he was all for long gallops instead of dressage work. I'm going to continue Ex-Stress for a little while longer and see, but I will most likely discontinue the use of it.

    Rated 5 out of 5 by from Works for us My mare seemed to have a bit of anxiety- just a little edgy and over-reactive. I tried Mare Magic and Magnesium and neither did much for her. She has been on Ex Stress for a couple months now, and the product seems to be a perfect match for her. She is the same horse- just a little less uptight and flighty. She seems more settled and her reactions more appropriate. A beach umbrella got loose and blew by the ring the other day- of course she startled (so did I), but she quickly got her composure back and listened to my reassurances. I am very satisfied with this product.

    Rated 5 out of 5 by from Good calming supplement My mare is on stall rest for 6 weeks following a suspensory ligament injury. This supplement has made it bearable for her. Best if mixed in some kind of mash so it doesn't fall through the grain to the bottom.
