I've used this supplement to help both one TB mare and my kids' Shetland mare who have sweet itch--i.e., reactivity to gnats/midges, that especially shows up along the midline. I'm in FL and it gets too hot even to use fly sheets, so this is a great solution. It didn't seem to do too much for itchy tails, perhaps because there's less circulation there? I had good luck with the BBI lotion for tails.

I bought this on clearance, used the whole tub faithfully on just one horse. No change. Never stopped the itch, and she has rubbed her tail hair completely off.

I don’t see any results. My poor horse is rubbing the hairs off the top of his tail as much as ever. My vet told me that he is allergic to gnat bites. The medicine I got from the vet didn’t work so I tried Bye Bye Itch. Very expensive and very disappointing.

I started my Irish sport horse on this product a month before it started getting warm here in upstate New York. It is now August and he has not lost ANY hair and is completely comfortable. I do not know if my extreme success with him is entirely due to this product, but there is no doubt that it was a contributing factor in his health this year. On top of adding this product to my horse’s diet I did a few things: I NEVER had him outside at dusk and dawn, he had a fan on indoors, outside he had a run in shed to have relief, he was groomed every day often using Equiderma horse lotion (amazing stuff), i did spot fly treatments down his mane and at the top of his tail as well as the upper inside of his legs every 2 weeks, and he was always turned out on the highest point of the farm to avoid dampness. Any sweet itch horse owner knows that even all of that effort does not do the trick for sweet itch, and that is why I know the product helped my horse somehow.
