Unlike most fibres, Sterculia passes through your gut gently. It absorbs water and swells into a soft, bulky gel, naturally increasing stool bulk without fermentation. That's what makes it so gentle, and why it suits sensitive guts.

That soft gel moves naturally with your gut, supporting regular, comfortable bowel movements without stimulants or harsh chemicals.
