Rated 5 out of 5 by from Great products I have been using this product for quite some time and it really keeps my boy sensible (for a better word). I have used most of the other brands of calming products, but none of them works as well as Ultra Calm. Thank you!

Rated 1 out of 5 by from Horse wouldn't eat it. I tried this for a couple of months and ended up throwing out almost all of it out of the bottom of my horse's gran bucket. He just would not eat it.

Rated 5 out of 5 by from Just what I needed I've had my horse on this for about a month and I'm already noticing a difference. He is on reduced work due to recovering from an injury, so I had cut his grain back so he wouldn't be bouncing off the walls with too much energy. The unfortunate side effect of this was that he did drop some weight, so I decided to try this supplement to see if I could get some weight back on him without having to up his grain again and cause unwanted hyperactive behavior. It worked! He's put some weight on already and his coat is shiny and dappled as well. The best part is that it didn't make him hot, which is what I was worried about. Definitely recommend.

Rated 5 out of 5 by from Amazing Product I absolutely LOVE this product!!! It has really helped my recent project pony gain much needed weight! She started out all skin and bones and this has really helped her in just the month that i have had this! If your looking for something for a hard keeper, this is definitely what you want to get!!!!

Rated 4 out of 5 by from good weight builder- wish it was pelleted My old man eats this, but I wish it were pelleted. I feed in feed bags and it gets wasted on the sides or falls through. Pellets would be wonderful.

Rated 3 out of 5 by from Needs more time I bought this a month ago for a thin aged TB gelding. Not seeing any results yet, but knowing how much he needs to gain, I'm giving it 90 days. Not giving up on this product yet.

Rated 5 out of 5 by from Four weeks makes a big difference! I bought this four weeks ago, started King my 26yr old cushingoid hard keeper on it right away with the intention to get as much weight on him as possible before our Minnesota winters hit. He had gained a little weight without it, but he’s quickly packing on the pounds with this in his regime! check out the photo. 9/28 is 4 weeks with SmartGain. This will likely be a regular on King’s Smartpaks. Also, he ate it no problem with his regular grain.

Rated 3 out of 5 by from Great supplement I originally bought this for two of my horses but one of them is a picky eater and would not touch it even if mixed with other food. This was recommended by smartpak for horses that are picky eaters so that would be my only complaint.

Rated 5 out of 5 by from Great product! I bought this for my draft cross who is 18 and has copd. I had tried everything! I come across smartpak and I’m so happy I did! He went from pretty underweight (200 lbs) to fat and happy!! So happy with this product!

Rated 4 out of 5 by from Helped! I believe this helped my gelding a good amount, I’ve been struggling to keep weight on him now that he’s working and gaining muscle he seemed thin and ribby even on grass two grain meals and all day hay. The only complaint is that my horse leaves some of it in his feeder. I mixed it with corn oil and he ate it though.

Rated 5 out of 5 by from This actually works I have a thoroughbred,ex race horse, ex eventer now broodmare that has always been a hard keeper. For the 7yrs I've had her it was like I couldn't feed her enough, tried so many different supplements with little success. I wasn't sure I would breed her this year because she just wasn't at a weight I liked. Smartgain was my next "supplement to try". I was very pleasantly surprised that after 1.5mo she went from ribby to perfect. I'm almost debating taking her off, I just have to watch that she doesn't get too fat! Nothing else was changed, just added the smartgain. I would definitely recommend over any other weight gain (and I've probably tried them all)

Rated 5 out of 5 by from Works! My 18 year old hard keeper came out of winter looking rough. He's been on this for nearly 3 months and it has made a world of difference in his weight and his coat is so shiny. I don't think he's ever looked this good. Now that he can graze all day I'm going to take him off the Smart Gain but I'm sure it will be a winter staple for us.

Rated 4 out of 5 by from Horse likes it I've only been using this for a few weeks, so I can't tell yet whether it is working. Hopefully it helps. My horse hesitated at the first feeding of it, but after that, no problem.

Rated 4 out of 5 by from It works My 32 year old hard keeper lapped this up and looks much better. I bought it again for my 23 year old mini. She also looks more full.

Rated 5 out of 5 by from Huge improvement in just one month! This is a great supplement. I bought a super underweight horse and quickly purchased this supplement. In just one month he put on substantial weight and it didn't change his attitude at all. He remained calm but started to have a bit more endurance in his training now that he was getting the calories he needed. I purchased three months worth and will finish it all and by then he should be at his goal weight. He also is a super picky eater but didn't mind this supplement.

Rated 5 out of 5 by from Awesome Product! I received two shipments of SmartGain for my oldest mare. She’d lost weight over the winter and I had been searching for something worth the price to give her. She put on the weight she lost after being on SmartGrain for two months. It was pretty awesome seeing her look so healthy after being worried about her weight loss.

Rated 4 out of 5 by from Pleasing I bought this with the intent of helping my horse build her muscle and topline. While the topline still has little improvement, her butt and shoulders have filled out and her back is getting there. I really started to see a difference a couple of weeks after having her on it and she yells at me if I don’t feed her this product. Thanks SmartPak!

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.

Rated 2 out of 5 by from No visible improvement I bought this product six weeks ago and have seen no improvement in either of the two horses I started on the supplement.

Rated 5 out of 5 by from He picked up weight fast! I started giving this to my 15 y.o APHA gelding 30 days ago. So far he has picked up so much weight! He was getting lean due to medical issues( EPM ). I was worried about him going into winter as hes always been a very easy keeper. Without feeding any more than usual he is back up to is usual weight! Very happy with this product and will continue to use.

Rated 5 out of 5 by from Finally... something that helps. Coming in to winter, I was worried how much feed I would have to feed to help Diamond gain/maintain his weight. Thank you for the easy answer!
