Rated 2 out of 5 by from Not picky eater approved. Disappointed. Fed this to my 34 year old gelding. He's not really a picky eater, but he tries to eat around this stuff and leaves it. If I leave it in his bucket all day, then he will come back to it for the evening feeding and clean it up because he is hungry. But, ultimately I didn't order it again because he started leaving his breakfast and not eating it all once I added this supplement.

Rated 2 out of 5 by from Unfortunately my gelding is refusing to eat this powder. He either pushes it to the side or he stops eating his grain. I plan on replacing it with something else I just can’t use this anymore.

Rated 5 out of 5 by from Great supplement I bought this over a month ago. Bleu couldn't put on weight as an off the track race horse who cribs. We put him on this and what a difference. He has gained weight and looks incredible. What a difference. So impressed with the product

Rated 5 out of 5 by from Good product I purchased this for my 30yr old mare. She has since added some good weight and her coat looks great! She eats it fine, I just mix it in with her regular grain.

Rated 5 out of 5 by from Works great I cannot recommend this enough. My 14 year old OTTB came out of winter looking so skinny and pitiful. About a month after using this daily he looks back to normal and dare I say even better than before. I plan to continue using this supplement.

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!
