H & B have a 1/2 price sale on at the moment and it includes the husks in capsule form . I defo wouldn't be without mine and at £5.99 (instead of normal £11.99) for 200 x 500 mg capsules they're quite a bargain at the mo
Some people find that on CD they become constipated as our inners need bulk to make us poop! The husks are a completely natural dietary fibre (carb free & very low in calories) and are available in the powder form or capsule form. They add the bulk we are lacking and hence stop us getting all blocked up.
I personally love the capsules - I take 2 capsules 3 times a day and since having them I have not suffered with constipation. Others prefer the powder form which they add to soups/shakes - gives a thicker consistency.
