I have started ordering products from Mad Barn USA. I believe in the quality of their products. I have fed California Trace Plus for several years and believe it is a good product. I feel that Mad Barn’s Amino Trace Plus and Omneity are a bit more comprehensive. As such, I have started feeding Amino Trace Plus to my horses in work and Omneity to my pasture ornaments. I love their chaste berry for horses struggling with metabolic or other hormone issues. I like their Jiaogulan for joint support. The Spirulina for those equines with some allergy issues. The 3:1 zinc copper is good for areas with high iron.
