The Buyer’s Angle is a research-based review site, not a lab. We don’t run
clinical trials on the products we cover—we do the work of reading,
verifying, and cross-checking so you don’t have to. Here’s exactly what that
means in practice.
What we check on every product
- Full ingredient transparency. We look for the complete
ingredient list and actual per-serving dosages. Products that hide amounts
behind a “proprietary blend” are flagged—you can’t judge effectiveness
or safety without knowing what’s actually in it. - Dosage vs. published research. When a product’s
marketing cites a study, we check whether the dose in the bottle matches the
dose used in that research. Underdosed “trendy ingredient” formulas are a
common way brands ride real science to sell something that doesn’t match
it. - Claims vs. what supplements can legally say. Dietary
supplements cannot legally claim to cure, treat, or prevent disease. Any
product making disease-cure claims (“cures IBS,” “reverses colitis”) is
flagged as a red flag, not a selling point. - Red flags we specifically watch for: proprietary blends
without disclosed amounts, “cleanse”/”detox” formulas built on harsh
stimulants, and pricing that’s implausibly low for the ingredients
listed.
Where our information comes from
We prioritize primary sources—PubMed, NIH/NIDDK, the American
Gastroenterological Association, the World Gastroenterology Organization—
over secondary blog content or brand marketing pages. Every claim about a
physiological effect is expected to link back to a source, not just an
assertion.
What we do when the evidence is weak
We say so, explicitly. If the research behind an ingredient is thin,
mixed, or based only on small/animal studies, that’s stated in the review
rather than smoothed over. A “does this actually work?” verdict of
“the evidence is limited” is a normal outcome here, not a failure of the
review.
Updates
Reviews are revisited when a product reformulates, a program shuts down,
or new research meaningfully changes the picture for an ingredient. The
“last updated” date on a post reflects a real content change, not a
cosmetic refresh.
