A brilliant product to keep my horse's digestive system in good health. Will always buy from Feedmark as so easy to order, and keep track of delivery.

I used it regularly for my horse, he eats it so I'm assuming he quite likes it .

Easy to order and delivered on time. I ordered the 6kg sack and this arrived in 2 x 3 kg bags which I really liked as the 3kg bag is the perfect size to refill the tub I originally bought & then I could recycle the thick brown paper bag it arrived in. The product seems good - my pony's sweet itch has been so much better this year which may be down to a few factors but I think the Brewers yeast is one of them!

Been feeding this for several months now and it's definitely made an improvement. Poos are a lot less runny and he's definitely less stressy
