One of my favorite products!


This by far the best product I have ever used for immune support. Great for an overall nutritional boost. Helps combat all the Florida "funk" !!

Worth every Penny!


I fed this to my horse knowing that I would be making the 15hour trek to Florida from Pennsylvania and she is grey so she has fairly sensitive skin. I was super pleased with the results, my horse made the drive arrived safely, lived on pasture board for 3 months while in Florida and drove the whole way home all with out any illness or skin "funk". This is a must for any horse that does a lot of traveling.

Great product


I use this product every time I travel with the horses. I put my horses on it two weeks before they go on the road. When I go to Florida I do not get the skin funk and I leave them on it the whole time. I am a 6 year user of this product.

Fabulous product!


Best product out there that can help supplement a variety of horses with different issues. Biggest improvement I have noticed is one older retired horse that had dry skin and prone to hives due to sensitivities to the environment due to cushings. Two weeks on this supplant and he has never looked better since he was in worn

Works well if your horse will eat it


Great product IF you can get your horse to eat it. It smells horrible, and is such a fine powder that when you scoop it into their bucket, it creates a dust plume of greenish/yellow powder. I hold my breath every time I open the container and have to distribute it to the feed buckets.

Keep your horses strong and healthy


With all of the traveling our horses do, this helps them stay strong and healthy.
