hi Annie
i looked on the health span website for the pro20 and it does give a good review, i have been trying to find something for my husband as he suffers from ibs and diverticutis, he won't take immodium unless its really necessary, but i have heard of psyllium husk, so i brought some from holland and barrett, and although its cured the diarrhoea it leaves him a bit bloated, so not sure if he will continue with them he suffers from hiatus hernia. could you tell me if these pro20 capsules help with diarrhoea. thanks
