This product is great! Clears up fecal water syndrome in my older mares for the winter when they're off pasture and on hay. I feed it with Madbarn's prebiotic every day during the cold weather. My one mare is a fussy eater so I do take about a week building up to the full dose when I first put them back on it to get her adjusted. I've tried all sorts of supplements over the years. Hands down Madbarn products are the best. The results I see in my horses are fantastic. We're lifetime customers.

Love the omenity! Keeps my 13 year old Ottb Gelding looking great!

Great product with great results.

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!

Love it

Horse refused to touch it. I tried everything but she won’t go near it. She even stopped eating her normal grain for 3 weeks after I tried introducing the oil slowly because she hated it so much. I ended up giving it away. I love mad barn but this was unfortunate!

Nothing but things to say about MadBarn product and staff

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!

Spirulina and MSM for Whiskey !

Everything I order from Mad Barn is delivered next day. Value and trust the product.
