Benefiber Fiber Supplement Powder Review

Benefiber Original is a clear, taste-free powder made from plant-based prebiotic fiber. The page states that it supports gut health by nourishing the good bacteria that naturally exist in the gut, and that it helps maintain good digestive health by supplying the fiber you need. The product is listed with several features: plant-based prebiotic fiber, dissolves in food and beverages, gluten-free, and sugar-free. The powder is available in 76, 124, 250, and 410 (Club Pack) teaspoon bottles. Supplement facts are linked from the page to the Haleon Benefiber site. The page explains that the wheat used has been processed to allow the product to meet the FDA requirements for gluten-free foods. Each serving of Benefiber Prebiotic Fiber Supplement contains 6g of dietary fiber, which is about 21% of the recommended daily value based on a 2,000 calorie diet. The FAQ says Benefiber Original is made from wheat dextrin, a plant-based fiber that is also a prebiotic. To use, add one serving to 4 to 8 ounces of any beverage or soft food, hot or cold, and stir well until dissolved for up to 60 seconds. The page notes it is not recommended for carbonated beverages. Adults and children aged 12 years and older can take 4 teaspoons once a day for digestive health, and may take 4 teaspoons twice a day for the benefit of helping them feel fuller, longer. The page also refers to the product label for complete product information. Statements on the page have not been evaluated by the Food and Drug Administration, and the products are not intended to diagnose, treat, cure or prevent any disease. The page also promotes related Benefiber formats, namely Prebiotic Fiber Caplets and On-the-Go Stick Packs, which are separate products with their own pages and sizes.
