I have used this product for a number of years for a mare that had several minor colics and has since had none. Also appears to be effective for my ex racer that more than likely would have suffered ulcers in the past.

great product that my animal loves

I bought this for my ducklings. It's exactly what I needed to help their growth and to prevent angel wing

Cheaper than other brewers yeast and this is the one my two gastric prone mares prefer. Helps with symptoms of hind gut problems particularly when spring grass has come through

Fantastic product, fantastic service & delivery

I've been using Feedmark products for years now and I keep coming back - great quality and value.

Excellent

Good quality and price, I also like the option to buy without a plastic tub
