If you’ve felt bloated, irregular, or just not “your best,” chances are your daily fiber intake isn’t hitting the recommended 25–38 grams. Busy schedules and convenience foods make it tough—so a high-quality fiber supplement can be a smart, simple way to support regularity, nourish your gut microbiome, and steady energy throughout the day.
Below is our Top 10 Fiber Supplement Brands for 2025. We evaluated fiber type and dose, added digestive support (enzymes/probiotics), digestive tolerance, ease of use, and overall value. Triogut takes the #1 spot for its comprehensive, 3-in-1 gut support.
How We Ranked These Brands

Added support: probiotics and/or digestive enzymes for total gut comfort
Digestive tolerance: minimal gas/bloating, gentle on the gut
