Overview

Supports a healthy weight & immune function

  • Provides a source of high-fat energy along with powerful antioxidants & direct-fed microbials
  • The perfect choice for hard keepers, top performance horses & seniors

EndurExtra was specifically developed for horses who need more than a diet of hay and grain can provide. EndurExtra’s special blend of ingredients supports a hearty appetite, a desirable body weight, a robust immune system, and healthy muscle function. EndurExtra’s concentrated blend of readily digestible fats is supplemented at the low rate of eight ounces per day. This formula contains 50% fat from several sources, including rice bran, soybean oil, and flaxseed, helping to eliminate the need for excessive grain in the diet. It also includes a proprietary blend of direct-fed microbials to help maintain normal digestive function, as well as natural vitamin E to support muscle, nerve, and immune health.

    EndurExtra® is rated 4.0 out of 5 by 6.
    Rated 1 out of 5 by from Terrible Bought it for a specific horse who wouldn't eat it. So I figured OK, let me try it on another less picky horse. Nope. So then just to see I offered it to the one that eats everything. NOPE. Terrible. It's also a rather large portion of a dusty powder. Worst part is when I emailed Smartpak they basically told me to try molasses or another flavoring to mask the taste .. really? You want me to pour molasses on this powder and make a sticky ball of goo? I seriously doubt that would be any more appetizing. These horses don't need pure molasses poured on their feed, no thank you. I thought Smartpak stood behind their products but this was not the case.

    Rated 5 out of 5 by from A powerful additive I recently moved states and one of my horses responded with a huge weight loss. I tried another guaranteed weight gain supplement x 6 weeks with only modest improvement (along her daily feed supplement). After using EndurExtra for a little over a month, I have seen massive gains--she is almost back to her pre-move weight. Very palatable, easy to feed, and well worth the investment.

    Rated 5 out of 5 by from Great results for not a lot of investment My OTTB preliminary eventer has been on this for 6 months now and he has absolutely blossomed. I have gone down the route of other fat supplements before but, after using this for 6 months, certainly feel like this is the best bang for the buck. It isn't the cheapest, but with the direct fed microbials and vitamin E I feel it certainly has the best value.

    Rated 5 out of 5 by from Great high fat supplement to put weight on The nice thing about this product is you don't have to feed a ton of volume to get the fat in. Works nicely for the senior, hard-to-keep-weight on horse. Very palatable, but even if you add water and make a drench, it's still a lot in a small volume.

    Rated 4 out of 5 by from good value supplement I bought this hoping it would help my OTTB keep weight on and I liked the added pro-biotic component to help his gut. He is not a fussy eater but he has enjoyed this in his food and he is in great condition
