iHerb product data: supplements, beauty and grocery
A source-specific guide to iHerb product data: Supplement Facts, ingredients, UPCs, package options, date fields and localized prices across beauty and grocery.
An iHerb item is different from its brand and selected package.
iHerb describes itself as a health-and-wellness retailer and says its orders are sold and shipped by iHerb rather than third-party sellers. Keep that retailer relationship separate from the manufacturer brand on each product. The listing's iHerb product code and UPC identify different things, while a selected count, flavor or formula belongs to the purchasable package state.

| Record | Fields to retain | How to interpret it |
|---|---|---|
| Retailer and seller | iHerb and the page's seller wording, with source and review date | The current About page says iHerb sells and ships its orders; a brand name is not a separate seller. |
| Manufacturer brand | Brand exactly as shown on the product page | Keep brand distinct from iHerb as retailer and from any product line or formula name. |
| iHerb product code | The source's displayed product code and product URL | Use it as an iHerb listing identifier; do not assume it is a universal product key. |
| UPC | The UPC exactly as displayed, including its identifier type | Keep it in a separate field from iHerb's product code; a UPC can help identify a packaged item. |
| Selected package | Count or net amount, flavor/formula and selected option when shown | A different count or formula can change the item being compared even when the title is similar. |
Supplement listings need a label-level field map.
For supplements, preserve what the listing and package actually state: product form and strength, serving size, servings per container, ingredient amounts and units, percent Daily Value when shown, other ingredients, allergens, warnings, directions and package quantity. Do not infer a health effect or suitability from a name, ingredient, filter or customer review. iHerb says product information may not yet reflect manufacturing changes; its Terms direct customers to follow the physical label or packaging when it conflicts with the site.

| Label field | Useful source detail | Evidence boundary |
|---|---|---|
| Product and serving | Dosage form, displayed strength, serving size and servings per container | Do not compare amounts until the serving basis is clear. |
| Supplement Facts | Ingredient name, amount, unit and % Daily Value when present | Preserve the label's unit and wording; do not calculate an unstated serving value. |
| Other ingredients | Listed excipients, allergens and capsule or tablet material when stated | Do not claim allergen-free or dietary suitability unless the current source says so. |
| Directions and warnings | Label directions, cautions and age or use qualifications | This is source information, not medical advice or a recommendation. |
| Package | Bottle count, net quantity and exact product option | Keep package count separate from servings per container. |
The useful filters depend on the iHerb category.
iHerb's current filter guide says available filters vary by category and may not appear on every page. Treat a filter as a displayed navigation facet, not a guaranteed attribute on every item. This distinction matters when comparing a supplement with a beauty product or a grocery listing.

| Store category | Examples of source-described filters | How to use the fields |
|---|---|---|
| Supplements | Potency, product form, formulation, diet or certification, package quantity | Record a facet only when the product page or selected filter exposes it; keep certification names exact. |
| Beauty and personal care | Skin or hair type/concern, ingredient, scent and brand origin | Do not add shade or skin claims universally; use the fields relevant to that product and category. |
| Grocery | Flavor and package amount | Keep flavor, net amount and pack count separate where the listing provides them. |
| Baby and pets | Age, pet type or weight-related options where shown | Preserve the intended audience and category context; do not transfer supplement facets. |
| Any category | Brand, rating, price, Autoship, offers or certifications when surfaced | Filters are page-dependent; their presence does not establish a stable catalog-wide schema. |
Manufacturing dates, expiry dates and test reports are separate evidence.
A manufacturing date is not an expiration or best-by date. For cosmetics, period-after-opening (PAO) describes an interval after opening, not a calendar expiry date. Keep each date type with its label and exact product. iHerb's iTested and Certificate of Analysis guidance is limited to iHerb Brand products and tested batches; reduced-frequency testing means a report is not available for every lot.

| Evidence type | What it represents | Keep separate from |
|---|---|---|
| Manufacturing date | When the product was made, if a source exposes it | Do not use it as an expiration date. |
| Best-by or expiration | The source or package's date for the product's stated shelf-life context | Retain the exact label; do not infer the date from batch or manufacture timing. |
| Cosmetic PAO | The stated use interval after opening, often shown with an open-jar symbol | It is not the product's unopened expiry date. |
| iTested / COA | A report associated with an eligible iHerb Brand product and tested batch | Do not mark every product or lot as tested or verified. |
| Source label or report | Page, package, report identifier and review date when available | A listing-level statement cannot replace a batch-specific report or current physical label. |
An iHerb offer is a dated, localized observation.
For a price or availability comparison, retain the storefront locale, currency, selected package, displayed price or unit price, availability, visible promotion and capture time together. iHerb's Terms say it cannot confirm a price until an order is placed and that errors may be corrected. Its Subscribe & Save annex says program details can change, including price, taxes, availability and shipping. Those program terms do not change iHerb's stated direct-retailer model into a third-party marketplace.

| Offer field | Record with the observation | Why it matters |
|---|---|---|
| Market and currency | Storefront locale and displayed currency | Prices across locales can represent different market and tax contexts. |
| Selected item | Product code, package/count, flavor or formula and selected option | A price without its selected package can compare different items. |
| Price basis | Displayed price, unit-price wording and any visible reference price | Keep a calculated unit price distinct from the source-displayed value. |
| Availability and offer | Displayed stock state, promotion, Autoship/Subscribe & Save eligibility and capture time | Eligibility and terms can change; do not treat a captured offer as evergreen. |
| Delivery or seller wording | Only the exact public statement and program context shown | The Subscribe & Save annex's change language is not evidence of a separate marketplace seller. |
Affiliate tools and site-use terms answer different questions.
iHerb's Terms of Use, last updated August 26, 2026, say to access the site through its provided interface and limit the Materials license to personal, non-commercial use; copying, republishing, selling or exploiting site materials requires written authorization. The reviewed Terms do not expressly say “scraping.” The separate Affiliate Program requires application and approval through third-party platforms and describes tracking, reporting, deep links, creatives and offers. Those marketing tools are not evidence of a general product-catalog endpoint or permission to reuse site content.

| Source material | What it says | What not to conclude |
|---|---|---|
| Terms of Use §5 and §13 | Interface-only access wording and a personal, non-commercial Materials license; copying and commercial exploitation require written authorization | Do not paraphrase this as an express scraping clause; these pages do not establish permission for automated collection. |
| Terms of Use §3 | Product information is not healthcare advice; the physical label or package takes priority when it conflicts with site information | Do not turn catalog fields or user reviews into health guidance. |
| Affiliate Program | Application/approval and affiliate marketing tools such as tracking, reporting, deep links, creatives and offers | Do not label affiliate features as a general catalog API or data feed. |
| Current facts | Terms page shows an August 26, 2026 update; page details and program terms can change | Recheck current source wording before relying on it; this summary is informational, not a legal determination. |
