Rated 1 out of 5 by from Made my horse crazy! Bought this for my 5 year old to help him improve his weight but within the first few days it made him crazy. I think it was too much for him all at once but I wish I had known this could have happened before purchacing. I believed the supplement could have helped his weight over time but it is not worth having a very spooky, energetic horse that his not like himself.

Rated 1 out of 5 by from Not picky eater approved My 37yr old shetland won't eat this no matter if it's soaked dry with beet pulp or sweet feed. Extremely disappointed especially with the price I paid.

Rated 5 out of 5 by from Best weight gain product out there I've been using Omega 40 for 3+ years for my now 26 yr old Peruvian Paso. Always had to stand by his bowl to make sure he ate. Switched to SmartGain a month ago. WOW! what a difference. He eats this right up and I'm already seeing him bulk up. CHEAPER & BETTER!

Rated 5 out of 5 by from Works Great! I have an old Arabian who was looking very thin no matter how much he was fed. I started him on the SmartGain and when the shoer came next time even he saw a difference in how he looked even though he had only been on the SmartGain for about 3 weeks!

Rated 5 out of 5 by from TB Anxious Mare looks like new horse! Hard keeper on my 27 year old TB mare. She can be quite anxious and after moving to a new barn I struggled to put weight on her. A friend suggested rice brown and I found this supplement. I am so happy with it, it's the best she has ever looked.

Rated 5 out of 5 by from It actually works! I own a 23 year old Friesian gelding and as he has gotten older, it's been harder to keep him at a healthy weight. He has a bad case of the old man teeth so getting nutrition from hay is hard for him. I was looking for something to add to his senior grain to add calories. At first i was using Nutrena Boost but it was not being made anymore. The lovely Annina suggested trying SmartGain. I am skeptical of supplements in general but was willing to give it a try. And amazing, it works! He has gained more weight on this than the Nutrena Boost, plus it's cheaper and easier to feed!

Rated 5 out of 5 by from Always does the job. I have used SmartGain on multiple Thoroughbreds multiple times over the years and it always puts on weight quickly without making them hot. I usually use it for about 2-3 months and then pull them off it until we end up needing it again. For my personal horse of 8 years I usually start him on it around February and pull him off of it in May. Needs a bit of extra help keeping the weight on after a long winter!

Rated 5 out of 5 by from amazing results My 27 yr old TB started on this a month ago. I had tried other weight supplements with no real results. Smart Gain has visibly changed his top line really fast. Yesterday I had to let his belly straps on his blanket out! He didn't like it at first, but is now licking it up. He has more energy, is playing with his buddy and is running around like a young guy. I am very happy!

Rated 2 out of 5 by from My horse does not eat well I started my 22 year old thoroughbred gelding on this in December. I have not been able to tell a difference. This supplement being a powder has a lot to do with this I think. Most of the time the powder is left in the bottom of his feed bucket. I have tried multiple methods of feeding this supplement but have been unable to get much in my horse.
