According to the National Institute of Health, the majority of Americans do not consume enough dietary fiber. Understanding what are Fiber Well gummies made of can help consumers make informed decisions about this popular supplement designed to bridge that nutritional gap.

Quick Summary

Fiber Well gummies are primarily made from polydextrose, a soluble prebiotic fiber that supports digestive health and regularity. They contain other ingredients like gelatin, water, sweeteners (sorbitol, sucralose), natural flavors, and color concentrates for taste and texture.

Key Points

Polydextrose: The primary ingredient providing soluble and prebiotic fiber in Fiber Well gummies.
Sugar-Free Formulation: The gummies achieve their sweet taste using sugar alcohols (sorbitol) and artificial sweeteners (sucralose).
Gelatin-Based: The chewy texture comes from gelatin, an animal-derived gelling agent.
Natural Flavoring: The fruit flavors are produced using natural flavorings and fruit juice concentrates.
Allergen Consideration: Consumers should note the presence of coconut oil and potential cross-contamination with other common allergens.
Prebiotic Effect: The polydextrose and other components contribute to nourishing beneficial gut bacteria for improved digestive health.

Core Ingredients of Fiber Well Gummies

Fiber Well gummies are a popular supplement from Vitafusion designed to increase daily fiber intake. The main active ingredient is polydextrose, a soluble prebiotic fiber known for its digestive benefits. To avoid added sugar, Fiber Well uses sweeteners like sorbitol and sucralose. The characteristic chewy texture comes from gelatin.

Polydextrose: The Main Fiber Source

Polydextrose, a synthetic glucose polymer, functions as a soluble fiber with prebiotic properties, nurturing beneficial gut bacteria crucial for a healthy digestive system. It is not fully digested until it reaches the large intestine, aiding in digestive regularity.

Sweeteners and Flavors for Taste

Fiber Well gummies achieve their sugar-free sweetness with sorbitol and sucralose. Natural flavorings and concentrated fruit juices provide the various fruit flavors.

Other Functional and Non-Medicinal Ingredients

Additional ingredients contribute to the gummies' form and features:

Water: Necessary for the gummy's structure.
Gelatin: Provides the chewy consistency and is derived from animal collagen.
Malic Acid and Citric Acid: Contribute tartness and act as preservatives.
Blend of Oils: Coconut and/or palm oils with beeswax or carnauba wax prevent sticking.
Color Concentrates: Natural colors come from sources like annatto extract and fruit concentrates.

Gelatin gives Fiber Well gummies their chewy texture but makes them unsuitable for vegetarians and vegans. Pectin, a plant-based alternative used in some other brands, provides a softer texture.

Prebiotic Benefits

Both polydextrose and inulin offer prebiotic benefits, supporting healthy gut bacteria and overall digestive wellness.
