I’ve had a good experience with Protek GI for helping with horse ulcer prevention. It seems to work well, but it is definitely on the expensive side. My biggest complaint is that it’s a powder—the powder gets everywhere and always makes me sneeze! Shipping also took a little longer than I’m used to, so I almost didn’t time my next order correctly. Overall, I like the product, but I’d love to see a less messy and wasteful format.
