Honest review.

Honest review — works as advertised but you've absolutely got to drink plenty of water with these or you'll feel a bit blocked up. Once I sorted the water thing, regularity improved noticeably. Inulin in there is a nice addition.

No more bloating.

Doctor recommended I increase my fibre and this was easier than chewing through bran every morning. Three-ingredient blend feels well thought through. No bloating after the first week.

Khalid M. Walsall · 7 March 2026
Great quality.

Quietly does its job. Took about a week to feel a difference. Don't expect a dramatic effect on day one — like the description says, fibre is a long game. Will keep on these.

Good routine.

My IBS has been calmer since starting these. Started with one a day and worked up to the full dose over a couple of weeks which I think helped. Capsules are easy to swallow.

Does what fibre supplements do.

Does what fibre supplements do. Not exciting but it works. The FOS and inulin combo is more thoughtful than just psyllium husk on its own. Four stars because the recommended dosing took a bit of figuring out at first.
