Very pleased with the zinc helping my horse with her immune system and I like the bags used no containers to trash

Great, palatable copper supplement for picky eaters! And Mad Barn service is also great--excellent prices, rapid order fulfillment and shipping.

Highly recommend pelleted supplements. These are mad from the best natural ingredients and highly palatable for the horse. Does not fall to the bottom of the feedbin like powders or make a mess like liquids!

Excellent product and service second to none.

So 2nd year using Spirulina and no antihistamines....it is keeping her sweet itch under control along with a fly sheet and mask

Optimum Digestive Health from Mad Barn has been a huge tool in helping my sensitive mare find a happy gut balance throughout weather changes or stressful events. She has had a few colics over the years but since starting this supplement she has been much more consistent and I fret much less thank goodness! High quality supplement that I highly recommend if your horse has a sensitive digestive system.

My black mare tends to brown out in certain areas on her body during the summer. The hair becomes rusty-colored and crispy. She already had some of this going on when I began the copper, about a month ago, and it is mostly gone, is soft, and what is left is gradually brushing out during grooming. Her coat all over is also much softer and silkier. She only gets a tiny amount of copper twice a day, top-dressed on her food.

My Mare came to us with a 3 month old foal on her side. Her utter never seemed full and she was very difficult to help gain weight. During her next pregnancy I consulted with the vets at Mad Barn to see if there was something we could give her to improve her milk production. They recommended the Optimum in the last trimester of the pregnancy. We did and the results were amazing, beautiful full utter(like night and day) and one happy colt.

Delivered timely and my fussy Mare actually likes it !!! We have noticed a difference with her sensitivities while she is in heat.

So far, this product has been great. My goal was to strength her feet to keep her bare foot and so far so good.
