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!

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

This product is amazing, my horse has diarrhoea problems. She has now been on this for three months and it has resolved. I have recommended this to a lot of other people at my barn and they have also seen amazing results.

Great as always! Keeps my boy healthy :)

So good for my 22 years mare that has cushing!

Didn't really notice a difference. Maybe I should try it for 3 months and see what happens.

I’ve been adding this to my pony and donkeys’ dinner for the last few years and they eat it with no issue. Seems to help them not have the splats, for the most part.

I used this to support gut health while my horse was on antibiotics for several weeks. It helped with his recovery

My senior mare (29 yrs) had issues with watery stools. It cleaned up with one packet of MadBarn probiotics. Now I use it every day - she's a happy, healthy camper!

Nothing but things to say about MadBarn product and staff
