Source (original formula) was the only consistent feedstuff that my horse had on a ride from Pennsylvania to Texas. He grazed every chance I could give him and ate whatever grain I could get each day, but he got a little scoop of Source every day. He had always had good hooves; he was fine barefoot or shod. As he stayed on Source, I could see a horizontal line in his hooves, and the hoof wall was denser and more solid as it grew out. His previously plain red sorrel coat shone with golden and copper dapples. He maintained good weight, despite the average 24 miles per traveling day and the irregular diet. More recently, I am using Source for a wild caught mustang mare with a lot of Thoroughbred blood. She'd been pregnant and nursing for at least a decade, and had a foal at her side, and she was at least 100 pounds underweight. With Source, she gained healthy weight.
I give this to all my horses - all of them are elderly. I think this helps them get better nutrition from the hay that they get, along with the summer pasture. They eat it without any hesitation.
I ordered Source micronutrients and the Source for weight gain. I can say the weight gain product was quite effective my little Arab/rescue who is a HARD HARD keeper. I struggle to keep weight on him, and any stress producing change for him will cause weight loss. I started him on the Source product and, even in late winter, could see positive effects as he started to gain. In addition, when my last shipment arrived the lids had come off and spilled into the shipping box. Corro IMMEDIATELY shipped and replaced the product -- they were very nice and responsive. Highly recommend the product and the company!
