    Rated 4 out of 5 by from Most horses seem to like it I have tried other more expensive electrolytes and a lot of my horses wouldn't eat them.This one seems to be more palatable than others - probably due to the sugar content, but like little kids and medicine, sometimes you have to sweeten it to get it down!

    Rated 5 out of 5 by from Only used it for a couple weeks so far. My horse is already drinking a lot more water.

    Rated 4 out of 5 by from Works well enough I started using this product on my half percheron when she was 7. She wouldn't eat it at first in sweet feed or grain; mixed in, on bottom, or on top. She also would not drink it either. Eventually she caved (about a year later) when I just kept giving it to her. It works well enough. She has not had a hydration issue since she started eating it consistently. However, I have to give her about 2.5 times as much as recommended in the summer than in the winter, though yes she is very large and in moderate training. I think I will switch to SmartLytes, because of everything else it has in it for the same price. if you wanted jsut a very basic electrolyte though and your horse is not picky, this product is good for that.

    Rated 5 out of 5 by from Great Electrolytes I love Stress-Dex, my horse has no problem finishing it up, as it being a supplement too! I would definitely recommend this product. It keeps your horse hydrated and gives them what they need!!

    Rated 5 out of 5 by from Peace of mind I live in a very hot area, and travel to other very hot areas to event. I've been warned to watch out for my horses' ability to sweat, along with their electrolytes. Now that they're both on stress-dex, I feel a lot more confident taking them out in the hot weather.

    Rated 5 out of 5 by from good choice My horse likes the orange flavor and doesn't mind it added to his grain. The large bucket is just the right size to last the hot summer.

    Rated 5 out of 5 by from Our Go-To Electrolyte There are times when you absolutely must have an electrolyte that your horse will eat/drink. This is the one for us. When my mare shows signs of mild colic, and it's cold so she doesn't want water, I can count on the fact that she will drink a bucketful of this. I wish I could find one as reliable as this one with less sugar, but when my horse is sick or not drinking, sugar is not our biggest problem. She also eats it readily mixed with her hay pellets, and drinks noticeably more when I give it to her.

    Rated 2 out of 5 by from LOVE THE PRODUCT- HATE THE LID!!! I fee this electrolyte every summer because itt works and my horse eats it(sometimes).I just ordered my first batch for this year and I COULDNT GET THE STUPID LID OFF!! I was so mad! They give you directions on the top of how to break the seal and open with a screw driver thing. I followed the directions explicitly and still could not get it open. I ended up having to destroy the lid to get it off and now it is open to the elements- I am sure my nice soft powdery substance will be hard and balled up due to moisture in about a week. I understand the need for freshness but now my cover wont stay back on.

    Rated 5 out of 5 by from The Best Electrolytes I keep my horse on electrolytes year round to keep him healthy and hydrated. I started using stress-dex as it is one I've been familiar with for years. Over a year ago I switched to another brand because it was said to have been better. But my horse didn't seem to think it tasted better and he always left it in his feed bucket. So I switched back and Doc is happily eating his electrolytes once again and I worry less that he's getting enough water in his system now that the warmer weather is returning.

    Rated 5 out of 5 by from Only electrolytes I will use I give my horse electrolytes year round because he gets overheated very easily and will colic, and I want to keep him hydrated. This is the only brand of electrolytes that sticks to the grain and that he will eat. All other kinds I have tried fall through the grain, and he ends up with a bucket full of electrolytes at the end of the week. I've been giving him Stress-Dex for 2 years (since we moved to hot, humid Tennessee) and he never leaves any in his bucket, AND has not been overheated or dehydrated once despite the summer weather here.

    Rated 5 out of 5 by from Great! My thoroughbred sweats A LOT. So much in fact, that people make fun of him! However, to replenish his body with water, I now use Stress-Dex in Smartpak form, year round. The cost is great and I know he is drinking enough water. Sometimes he doesn't eat all of it, but he almost always eats over 95%! Thank you Smartpak for another affordable, great quality supplement!

    Rated 5 out of 5 by from Perfect for the Picky Eater This product has worked amazingly well. Training a green jumper takes a lot out of a horse, and proper hydration is essential. My gelding refused to eat the three other kinds of electrolytes I had tried with him. He loves the orange taste of the Stress-Dex. It is also very nice that he doesn't need to be given as much as other supplements require. In other kinds, he had to be given two to four ounces. With this he only needs one ounce! Stress-Dex is a great product, and I'll continue to use it as long as he needs an electrolyte.
    Date published: 2007-07-02
    Rated 5 out of 5 by from Great Product Stress-Dex works well in small doses. I had a horse that had traveled from Florida and the people that trailered him gave him no water for two days, so when he got to us he was very dehydrated. I put him on Stress-Dex to get him back to health and he started drinking as soon as we gave it too him. Now we keep him on a .5 scoop because he isn’t a big drinker and when he would normally drink half a bucket he now drinks one and a half. Overall I am thrilled with this product!

    Rated 5 out of 5 by from Excellent for picky horses ! If you have had bad luck in the past with trying to get your horse to eat electrolytes, look no further! I haven't found a horse yet that doesn't like Stress-Dex!

    Rated 5 out of 5 by from I recently bought Stress-Dex to try to increase my pony’s water intake while he was colicing. He is really fussy and doesn't like any additives in his food or water. After trying several other types of electrolytes, we finally had success with Stress-Dex. During this medical crisis Stress-Dex proved to be vital in improving his health.

    Rated 4 out of 5 by from Excellent for picky eaters Stress-Dex is the only electrolyte that my picky TB gelding will eat. We live in hot, humid Houston and work all summer long. He has also completed a 3DE* whilst on Stress-Dex and maintained an excellent level of hydration.
