Momentous Fiber+ combines psyllium husk, Solnul® resistant potato starch, and rice bran hull in a Pure Cinnamon powder. The three fiber types work together to support regularity, a balanced gut microbiome, and digestive comfort. Each two-scoop serving supplies 6 g of dietary fiber. The resistant starch nourishes beneficial gut bacteria, while psyllium and rice bran help support smooth transit. Stir it into water, blend it into a smoothie, or add it to yogurt and other foods. If you are new to supplemental fiber, begin with one scoop and gradually increase to the full serving.

Its soluble, insoluble, and prebiotic fibers support microbiome balance, digestive regularity, nutrient use, and steadier energy alongside a balanced diet.
Psyllium helps hold water in stool, rice bran adds bulk, and resistant starch nourishes beneficial bacteria. Use consistently with sufficient water.
Regularity may change within a day or two. Microbiome support and steadier energy may take several weeks of consistent use.
It is made for daily use. Adults generally aim for about 25–38 g of dietary fiber per day. Start with a smaller amount if increasing fiber intake and drink plenty of water.
Most supplements can fit alongside it. Take Fiber+ at least two hours apart from iron or prescription medications unless your healthcare provider advises otherwise.
Momentous lists every finished batch as NSF Certified for Sport®, including screening for prohibited substances and label verification.
