What it does: Fiber supports digestive health by bulking and softening stool for regular bowel movements, while also providing food for beneficial gut bacteria. Soluble fiber is known to help maintain healthy cholesterol and blood sugar levels.
How it is used: Most commonly, fiber is taken to improve digestive comfort, promote regularity, moderate appetite, and contribute to heart and blood sugar support when dietary intake is insufficient.
Natural sources and supplement forms: Natural sources are fruits, vegetables, legumes, whole grains, and seeds. In supplements, fiber is found as psyllium husk, inulin, methylcellulose, acacia fiber, oat fiber, and others, in powder, capsule, or chewable forms.
Why it appears in supplement formulas: Brands include fiber for its role in supporting regular digestion, managing appetite, and contributing to overall wellness, especially where diets may be low in plant foods.
What to know before use: Rapidly increasing fiber intake can cause gas, bloating, or discomfort—introduce it gradually and drink plenty of water to reduce digestive issues.
Fiber: Found in Plant Foods, Added for Digestive Support
Fiber is a type of carbohydrate that your body can’t digest, found naturally in fruits, vegetables, whole grains, and legumes. In supplements, it's often included because most people don’t get enough fiber from food alone, making these products a convenient way to increase daily intake and support regular digestive function.
