About supmane

Who we are

Data sources

• DSLD (US NIH): labels of US supplements
• Foods with Function Claims notifications (Consumer Affairs Agency, Japan): Japanese Foods with Function Claims
• Google Patents: ingredient patents
• PubChem and FDA UNII: ingredient identification

Where our wording differs from the original data, the original takes precedence. See the Data Sources & Citation Policy for details.

How we handle the data

We organize the original data by these rules.

Lists show on-market products with their latest labels

Off-market products and older labels of the same product are left out of lists, counts, search and sitemaps. Their product pages stay so that links keep working.

Ingredients are grouped by UNII

Spellings that share a code are treated as one ingredient. Ingredients without a code are handled by name. Abbreviations and other names are merged only when confirmed to be the same substance.

Supplement Facts and other ingredients are kept apart

Ingredients inside the Supplement Facts panel are kept apart from the “other ingredients” outside it. The source has no amounts for the latter, so no amount columns are shown for them.

Unit spellings are aligned

Spellings such as g and Gram(s), or mcg and ug, are aligned before amounts are compared. Equivalents such as mcg DFE are treated as different quantities.

Japanese products come from notification documents

Japanese Foods with Function Claims are built from the Consumer Affairs Agency notifications. Ingredient names and amounts follow the notifications.

English names follow the source

Ingredient names are shown as they appear in the DSLD. For common vitamins and minerals we use familiar names (such as Vitamin C for Ascorbic Acid) and show the original name alongside.

Editorial policy

• We do not state that any product or ingredient has a definite effect, or claim that anything diagnoses, treats, cures or prevents disease.
• We do not use rankings or superlatives such as “most popular”, “best-selling” or “No. 1”. Lists are sorted only by criteria we can state, such as date added, name or amount.
• A patent is not government approval of efficacy or safety. We do not link patents to effects.
• Articles separate what is known from what is not, and cite their sources.
• Advertising never changes what we list or how we order it. A notice at the top of each page says the site contains advertising.

Updates and corrections

We re-import the data as the original sources are updated.

When an error is reported, we check it against the original data (such as the DSLD label) and fix it if confirmed. If the original data seems wrong, we leave it as is and note that the original takes precedence. If our import process caused the error, we fix every page with the same cause.
