About OptiFiber Lean
OptiFiber® Lean is a 100% natural, soluble dietary fibre supplement designed to support satiety, weight management, metabolic health, and digestive balance.
It features Shimizu Propol® A propolmannan — a highly purified fibre to ensure stability and efficacy throughout the digestive tract.
Propolmannan absorbs water and forms a viscous gel in the stomach, helping you feel fuller for longer and reducing appetite, making it easier to manage portion sizes and support healthy weight control. It also helps slow the absorption of carbohydrates and fats, supporting balanced blood sugar and cholesterol levels.
As a prebiotic, it feeds beneficial gut bacteria and supports healthy digestion and regular bowel movements without harsh laxatives. This makes OptiFiber® Lean a gentle, natural solution for daily fibre support and long-term metabolic wellness.
