Works really good, my fussy eater really enjoys it too .

samantha shaw (Exeter, GB)
great product for ulcers

I use gastro-mag alongside omaprazole as a more long term solution to help my horse with ulcers. He is noticeably better with gastro mag. Great service too and the chocolates were also appreciated with the order!!


Really good product and we have noticed a huge difference in our horses.
