I have started buying these bars on a regular basis now. They are delicious, they satisfy my hunger and they are good for my gut. I used to have a lot of problems with my digestive system, but it is far more well-behaved now, and I would recommend these bars to anyone. The peanut butter ones are my favourite,as the others are too sweet for me.

A very handy source of fibre, I have one for breakfast after my cooked breakfast. A great way to start me off on my fibre tally through the day. My digestion is far healthier than it used to be. I had all sorts of aches and pains and accidents, but now my gut is happy, and so am I. Thank you.
