Buying advice

When choosing a fiber supplement consider the type of fiber (soluble vs insoluble), any sensitivities, dosage convenience and price. Soluble psyllium products like Metamucil and Konsyl are great for bulking, while plant-based blends such as Garden of Life offer prebiotic benefits. For sensitive stomachs, low-fermenting options like Heather’s Tummy Fiber reduce gas. Always start with a small dose and increase with water to avoid discomfort.
