    Rated 5 out of 5 by from Worked Wonders for my OTTB! I had my horse on full board at a farm and somehow he managed to lose quite a bit of weight. I moved barns and started him on SmartGain with some electrolytes as well. This move and the supplement were in January of 2017, by June of 2017 my horse looked great and I was able to switch from SmartGain to SmartDigest to help maintain the weight. I cannot express how much I love this product and the wonders it did for my horse. The pictures are before and after. My horse has been able to maintain the weight with the help of SmartDigest and overall we have just had a wonderful experience with SmartPak.

    Rated 5 out of 5 by from Worked great. I gave this to my horse for the reasons to help gain weight, and it had a pro-biotic to help his digestive track. I gave it to him and within 30 days (The normal amount of time to really see change) he began to put on the extra weight he needed. Helped since we are also working to get in shape for summer.

    Rated 5 out of 5 by from Super results on senior thoroughbred I’ve had my hard keeping senior thoroughbred on SmartGain for 6 weeks in conjunction with a consistent light work load and I am very happy with the results. He has put on weight and muscle and finally rounded out over the rump with a nicely developing top line. A known finicky eater, he doesn’t bat an eyelid at the supplement mixed with his grain. Very pleased and will continue using this as he ages.
