  "methodology": "None of the 5 verified inulin products have a label-confirmed inulin-grams-per-serving figure this session — the Amazon Creators API used for price/title verification does not return supplement-facts data (Nutricost Organic's \"7g of fiber in each serving\" is a listing claim, not independently confirmed). Per editorial policy, we do not publish a precise cost-per-gram-of-inulin ranking for any of these five products. Instead costPerOz = price / verified net package ounces (an exact figure from the package size, no serving-size estimate involved) ranks the 4 powder SKUs; costPerCapsule = price / capsule count for the one capsule SKU. One of the four powder SKUs (Nutricost Prebiotic Fiber Unflavored) is a BLEND of soluble plant fibers, not single-ingredient chicory inulin, per its own listing — flagged as isBlend:true and excluded from the \"cheapest pure inulin\" figure even though its raw cost-per-ounce is lowest. Dose spine: typical prebiotic dose 5-10g/day; start low around 2.5g/day and titrate over 1-2 weeks (inulin-type fructans reliably cause gas/bloating — Wilson 2019 found they significantly worsened flatulence in IBS/functional-bowel patients even as bifidobacteria rose); Nagy 2023's flagship bifidogenic meta studied 3-20g/day (2 of 7 authors are BENEO GmbH, a commercial chicory-inulin manufacturer — disclosed every time that meta's effect size is cited); Abrams 2005/2007's calcium-absorption/bone-mineralization RCT used 8g/day in pubertal adolescents specifically, not adults. This statement has not been evaluated by the FDA; these products are not intended to diagnose, treat, cure, or prevent any disease.",
