When our weather got miserably hot and humid this summer, my Dreamy seemed to struggle with the heat. He is a highly fit FEI horse who had never had trouble with humidity before, so I wasnt sure what to do to help him. I asked Jeff for advice. He had me add MetaLyte to Dreamy's ration and I started seeing improvement within a few days. Now, I give him 1 scp per day at home, unless it's hot, and increase to 2 scps a day at shows. I like that it has no sugar and yet is highly palatable...an uncommon combo for electrolyte powder. Thanks for another great product!
