Soluble corn fiber is a prebiotic dietary fiber made from corn. It dissolves easily in water and ferments well in the gut. The mild taste and low gas profile set it apart from many other fibers.
People take it to support regular digestion and feed beneficial gut bacteria. It may also help blunt blood sugar spikes after a meal by slowing how fast the body absorbs carbohydrates.
You can find it as a standalone powder, mixed into bars and drinks, or in capsules. Stir the powder into water or food. Start with a small dose and raise it slowly to keep bloating at bay.
Taking too much too soon can cause gas, cramping, or loose stools. No major drug interactions are on file. Anyone with a corn allergy should skip it.
