I've been really happy with Mad Barn's Optimum Probiotic. It is a small packet, a small amount to add to feed, with no fillers. My 22 year old Arabian mare, who has very discerning taste buds, does not mind this probiotic at all, compared to others that I've tried. I also changed her feed with the help of Mad Barn nutritionist, and she is doing very well with her carpal arthritis and PPID. Thank you, Mad Barn!

Work great on my horse who has ulcers

I have been using this Probiotic for a couple years. I love the fact that you only need a small amount and it is so easy to mix with your feed. I will continue to be a loyal customer.

Haven’t really seen any difference in my horses energy, behavior, or perforomance ever since I started using it, not really effective.

Love this product and ended up getting one for my friend who now uses it regularly!

great product easy to use

Mad barn customer service is awesome. Had an issue with the packaging and was replaced, no hassles and very prompt!!

It's affordable and a great product, thanks!

It’s is great. I just ran out and need to go buy more this week.
