Evidence before opinion

Review Methodology

We separate a source-based product guide from a first-person product review. The first can explain verified catalog facts; the second requires real use, original evidence, a named contributor, and transparent limitations.

Stage 1: identify the exact US product

We record the US product name, product ID, category, official /us/en-us/ URL, affiliate URL, format, flavor or variant, package detail, caffeine notice, price, and check date.

Stage 2: separate facts from interpretation

Visible label and catalog facts are summarized narrowly. Editorial text explains why a difference may matter when comparing formats, but does not convert a structure/function statement into a medical promise.

Stage 3: balance practical positives and limitations

Every core guide includes both practical positives and considerations. Price, sugar or sweetener, caffeine, measuring format, warning coverage, and variant ambiguity are treated as decision information rather than buried fine print.

Stage 4: first-person evidence gate

A publishable experience needs a named contributor, product in hand, exact US variant, original permission-cleared photos, documented test period, preparation notes, taste and convenience observations, and conflict disclosure.

The reviews page is indexable because it contains source-based editorial reviews, not customer testimonials. First-person experiences and star scores remain unpublished until the evidence gate is met.

Rechecks

Core catalog availability, prices, warnings, and links should be reviewed every 30 days. Material changes trigger a data update and a real page-modified date.
