Observed on public, signed-out US/English product pages in September 2026. Use a plain fetch first; if it times out or returns an incomplete page, inspect the rendered product page. No account or cart operation is needed for labels.
Identity and layout
- Product URLs use
/pr/<descriptive-slug>/<numeric-item-id>. Slugs can change on redirect, including an addeddiscontinued-item, while the numeric ID stays the same. Verify the final ID, selected package and UPC; a similar name is not sufficient to substitute another item. #name/[data-testid="product-name"]is the selected product heading.#product-specs-listcontains product code, UPC and package quantity.- A package selector can offer several counts or strengths. Retain the selected variant's identity alongside any extracted facts or prices.
Supplement Facts: two observed layouts
- Active pages may have an already-visible
.supplement-facts-containerwith a table containing serving size, servings per container and labeled amounts. - A discontinued page used a collapsed
[data-toggle-type="product-supplement-facts"]header and#product-supplement-factsbody. Find the visible header's button in the accessibility tree, scroll it into view, click, then verify that the facts body is visible before extracting it.
Do not require an accordion on every page. Do not try to click the zero-sized rectangle of a hidden body. After scrolling or expanding, allow layout to settle and verify the full table visually. Capture the facts container, not just its heading. Other ingredients may be in an adjacent block.
Discontinued-product and price traps
.product-summary-unbuyable-messagecan explicitly say the item is discontinued and no longer available.#product-actionmay be empty in this layout; it is not a reliable lifecycle source on its own.- The same page can prominently show a Similar Recommendation with a price. That price belongs to another product, not the discontinued item.
- Active buying panels can show subscription, one-time and promotional prices together. Keep purchase type, package, currency/region and capture time attached; do not treat the lowest visible number as the one-time price.
- Page-wide text includes categories, recommendations and reviews. Searching the entire body for an ingredient can falsely attribute another product's formula to the selected item. Use its actual Supplement Facts and other ingredients.
- A retailer discontinuation notice concerns that retailer listing; it does not establish that the manufacturer discontinued the product globally.
Preserve label wording and serving basis. A salt amount, an ingredient amount "as" a salt and a free-form amount are not automatically interchangeable.
