Evidence and visible gaps.

Sources and dates

Product values come only from public manufacturer pages and their public product data. FDA excerpts provide the separate reference. The supplied research records robots.txt checks before retrieval; saved policies are in research/robots. Source URLs, retrieval dates and methods are recorded in each cache header. These records were retrieved October 28, 2026. Live pages may change.

Every build checks exact source excerpts against local caches. No network requests are made. Updates are manual and require another review of robots rules and terms. Missing serving text stays missing; no estimates are substituted.

Percentages compare one stated product amount with the FDA's 400 mg/day figure for healthy adults. They are arithmetic comparisons, not consumption targets, and do not apply to people who are pregnant or breastfeeding, children, teens, or people with heart conditions or caffeine-interacting medications. Serving wording and product notes qualify the stated amounts; a missing serving size is not inferred.
