For licensed practitioners. This tool offers evidence-informed suggestions to support your clinical judgment — it is not a diagnosis, prescription, or medical advice, and it does not replace individualized assessment. Fiber selection criteria are informed by the GastroANP 2025 Prebiotic Fibers quick-reference guide (Dr Sharon Erdrich) and its reference list, Hawrelak’s prebiotic reviews, and established prebiotic literature. Introduce fibers gradually, individualize dosing, and review each blend before recommending it.
