I also like SmartPak supplements. I second MIEventers statement that the customer service at SmartPak are exreatmly helpful, supportive, and don't push thier products. In fact, the rep that I was talking to evaluated my situation asked specific questions of what my vet diagnosed and recommended then suggested a simple supplement that I could get at my local feed store as well as 2 of the SmartPak supplements. I could have gotten the simple supplement from them online, but it was always mixed with other things that my horse didn't need, and the rep made a point of telling me so that I could save a little money. As MIEventer also stated, this was for a specific circumstance.
My everyday, all around supplement is EquiPride. It is like a daily vitamin for all the horses internal functions and a conditioner for skin and coat, plus minerals for healthy hooves... great product! All of my horses get this supplement everyday, currently 4 horses. I can get it at my vet tax free for $45 for a bucket, lasts just short of a month.
One is closer to God's heart on a horse than anywhere else on earth!
