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

Adding the flavour used in W-3 Oil would boost this rating to 5* like a rocket at take off. Palatability of Optimum Probiotic is sadly an ongoing issue. Small amount and tiny packaging and great price - 10* on a 5* scale. Congrats!

This is an excellent probiotic to help support a healthy gut function. My 20 year old quarter horse gelding is prone to spring time gas colics but they stop happening as soon as I add probiotics to his feed. Our other 22 year old horse gets quite a hay belly in the winter, but once I add these probiotics to his feed his belly gets noticeably smaller and I can tell he is feeling better and has more energy. Definitely a product I would recommend!
