Great for my hard keeper mare!


Love it! I've had this mare for 12 years. For the past several years she's alway had puffy back legs and stiffness since she has been on this all the puffiness had gone and the stiffness has lessened! Her hair coat is soft and shiny. Has help with her feet too. She is my hard keeper! With a very large foal at her side she kept good weight!

Well worth it


I got this stuff to put weight on my 33 year old gelding. I used omega gain for 2 months and it completely turned his weight around to a nice healthy weight. I would definitely give this a try if your having a hard time putting or keeping weight on your horse.
