Understanding Prebiotic Fiber and Benefiber

Benefiber is a dietary supplement designed to support digestive health using prebiotic fiber. The original powder's active ingredient is wheat dextrin, a soluble fiber certified gluten-free by FDA standards. Prebiotic fiber nourishes the beneficial bacteria in your gut, which is crucial for healthy digestion and overall well-being. The unflavored powder dissolves completely in many foods and beverages, making it easy to incorporate into your daily routine.

How Benefiber Works to Support Digestion

The soluble fiber in Benefiber travels to the colon, where it is fermented by gut microflora. This process feeds good bacteria and produces short-chain fatty acids (SCFAs), important for colon health.

Promoting Digestive Regularity

Benefiber helps promote regularity and relieve occasional constipation by adding bulk to stool and attracting water to soften it, facilitating easier passage. This is particularly helpful for those not getting enough dietary fiber.

Nourishing the Gut Microbiome

As a prebiotic, Benefiber supports a balanced gut microbiome by nourishing existing good bacteria. A healthy microbiome aids nutrient absorption and overall digestive tract function.
