Definitions

The names and the quantitative amounts by weight of each dietary ingredient shall be presented under the heading "Amount Per Serving." When the quantitative amounts by weight are presented in a separate column, the heading may be centered over a column of quantitative amounts, described by paragraph, if space permits. A heading consistent with the declaration of the serving size, such as "Each Tablet Contains," or "Amount Per 2 Tablets" may be used in place of the heading "Amount Per Serving." Other appropriate terms, such as capsule, packet, or teaspoonful, also may be used in place of the term "Serving."

For the DSLD, the "amount per serving" field lists the amount of the specific dietary ingredient found within one serving (i.e. 50mg in one pill, 10 IU per teaspoon, etc.) as stated explicitly on the label.

The following flags describe the two ways which blended ingredients, ingredients contained within a proprietary blends, are represented in the DSLD database. Since a proprietary blend may or may not include a Dietary Ingredient with RDIs or DRVs with it's individual weights declared.

Name given to a product by a manufacturer or distributor. For product descriptions in the DSLD, if no brand is identified, this field is coded as "generic". If a hard copy label is available, upper-and lower-case is preserved as it appears on the label.

Many products include after their brand name a symbol that indicates the Brand name, and often a specific statement about the product, are protected as corporate intellectual property (IP). Examples include symbols such as ©, ™, (SM), ® and wording such as "Quik-Sorb (R) is a registered trademark of Bio-Botanica (R) Inc.".

"Country of Origin" is a product description field specific to this database. If country of origin is explicitly identified on the label, this field will contain a text descriptor of that item number exactly as it appears on the label. If a hard copy label is available, case will be preserved.

The DSLD database contains the full label contents from dietary supplement products produced for distribution or sale. Dietary supplement products are grouped into three categories:

• DSLD On Market: a dietary supplement product or specific formulation of a dietary supplement product that is currently available on the market at the time the database was last updated.
• DSLD Off Market: a dietary supplement product or specific formulation of a dietary supplement product that was previously sold but is no longer available on the market.
• NHANES: Those products that were consumed by NHANES participants.

The categories of dietary supplement products can be searched together or independently in the DSLD via Advanced Search page.

The date on which the label information was entered into the DSLD after being verified through the contractor's quality control process.

The date on which the label went off market.

The date on which the label was recalled by the FDA.

The date on which the label was recalled voluntary by the manufacturer.

The date on which the label information was requested to be rescanned into the DSLD to be verified through the contractor's quality control process.

In the U.S., the Dietary Supplement Health and Education Act (DSHEA, Public law 103-417, October 25, 1994, 103rd Congress) defines a dietary supplement product as

"a product (other than tobacco) intended to supplement the diet that bears or contains one or more of the following dietary ingredients: a vitamin, a mineral, an amino acid, an herb or other botanical; or a dietary substance for use to supplement the diet by increasing the total dietary intake; or a concentrate, a metabolite, a constituent, an extract, or a combination of any ingredient described above; and intended for ingestion in the form of a capsule, powder, softgel, or gelcap, and not represented as a conventional food or as a sole item of a meal or the diet."

DSHEA amends the Federal Food, Drug, and Cosmetic Act of 1938 (FDCA) to alter the way dietary supplements are regulated and labeled. DSHEA was enacted by Congress following public debate concerning the importance of dietary supplements in promoting health, the need for consumers to have access to current and accurate information about supplements, and controversy over the Food and Drug Administration's (FDA) regulatory approach to this product category.

The DSLD ID is a unique identifier specific to the DSLD database and different from the NHANES ID.  The DSLD ID is assigned to a product with a Dietary Supplement Facts Panel that is unique in product name, net contents, ingredients and/or target group.  IDs are assigned regardless of whether the product is on-market (currently produced) or off-market (no longer produced).

The DSLD is a public use database designed to contain label information from virtually all dietary supplement products offered for sale in the US. The DSLD includes products on, off market, and those consumed by NHANES survey participants.

The Dietary Reference Intakes (DRIs) are nutrient reference values developed by the Institute of Medicine of The National Academies and Health Canada. They are intended to serve as a guide for good nutrition and provide the scientific basis for the development of food guidelines in both the United States and Canada. These nutrient reference values are specified on the basis of age, gender and life stage and cover more than 40 nutrient substances. The DRIs comprise four sets of values:

1. Estimated Average Requirement (EAR) by age and gender. The EAR is at the midpoint, where 50 percent of the population would meet the end-point criterion.
2. Recommended Dietary Allowance (RDA) based on the estimated average requirement. The RDA, calculated as two standard deviations above the EAR, is the intake level at which, theoretically, 97.5 percent of the population would meet that end point criterion.
3. Adequate Intake (AI) level. AIs are set when data are insufficient to establish an EAR. The AI for a nutrient is a recommended average daily intake level based on observed or experimentally determined approximations or estimates of nutrient intake by a group (or groups) of apparently healthy people and is assumed to be adequate.
4. Tolerable Upper Intake Level (UL) are defined as the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects for almost all individuals in the specified life-stage group.

The DRIs are not used in labeling of dietary supplements and should not be confused with the daily values used in labeling.

Refers to dosage information specific to certain populations such as adults, children, mature adults, pre-natal, or infants.  For supplements included in the DSLD, the formulation values are aggregated values to reference Dietary Reference Intake (DRI) values. When a formulation target group does not specify both gender and age group, the assumed target is an adult male, 19 to 30 years old.

The DRI Life Stage Groups are not used in labeling of dietary supplements and should not be confused with the intended target group based off the DV used in labeling.
SOURCE: IOM's, Dietary Reference Intake Reports

Daily Value comprises two sets of dietary standards established by the FDA for labeling purposes:

1. Daily Reference Values (DRVs) and
2. Reference Daily Intakes (RDIs)

Refers to dosage information specific to certain populations such as adults, children, infants,  etc.  For supplements included in the DSLD, the values are based on Appendix B and C of the FDA Dietary Supplement Label Guide. Percent DVs are based on the values provided in these two appendices and are not based on the Dietary Reference Intakes (DRIs) established by the Institute of Medicine. The DVs for "Adults and Children 4 or More Years of Age" is also known as the Food Labeling Guide Reference Values. The DVs for "Infants," "Children Less Than 4 Years of Age," and "Pregnant and Lactating Women" when calculated are based on published values in the Federal Register. When a formulation target group does not specify for a gender and age group, the assumed target is "Adults and Children 4 or More Years of Age."

The FDA is responsible for protecting the public health by assuring the safety, efficacy, and security of human and veterinary drugs, biological products, medical devices, our nation's food supply, cosmetics, and products that emit radiation. The FDA is also responsible for advancing the public health by helping to speed innovations that make medicines and foods more effective, safer, and more affordable; and helping the public get the accurate, science-based information they need to use medicines and foods to improve their health.

By law, the Food and Drug Administration (FDA) requires the following language on a dietary supplement label if the label also includes a structure/function claim: "This (These) statement(s) have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease." The wording of these disclaimers cannot be modified.
SOURCE: U.S. Government Printing Office via GPO Access - 21 CFR 101.93(c)

A Statement of Identity is required on all dietary supplement products. The statement of identity for a dietary supplement is its common or usual name or an appropriately descriptive term, as specified by Federal law or regulation. It must be placed on the principal display panel and on alternate principal display panels, if present.

Dietary supplements shall be identified by the term 'dietary supplement' as a part of the statement of identity, except that the word 'dietary' may be deleted and replaced by the name of the dietary ingredients in the product (e.g., calcium supplement) or an appropriately descriptive term indicating the type of dietary ingredients that are in the product (e.g., herbal supplement with vitamins).

Hence if a structure/function claim is included on the product label then the Food and Drug Administration (FDA) requires a statement that specifically identifies the product as a vitamin, mineral, herbal/botanical or dietary supplement.

Examples include: dietary supplement, calcium supplement, vitamin supplement.

There are several ingredient categories in the DSLD database such as: amino acid, botanical, carbohydrate, fat, fatty acid, fiber, mineral, other, protein, and vitamin. These will eventually be categorized based on LanguaL.

This term is being used to categorize dietary ingredients in this database. Amino acids are biologically important organic compounds. They are alpha-amino carboxylic acids (composed of amine (-NH₂) and carboxylic acid (-COOH) functional groups), along with a side-chain specific to each amino acid.

(The FDA has not defined what is an enzyme as a dietary ingredient) Enzymes are proteins that act as a catalyst in biochemical processes. This term is being used to categorize dietary ingredients in this database.

This term is being used to categorize dietary ingredients in this database. A solid homogeneous crystalline chemical element or compound that results from the inorganic processes of nature.

To be determined. This term is being used to temporarily categorize dietary ingredients in this database, pending further review for final classification.

Any of various organic substances that are essential in minute quantities; act especially as coenzymes and precursors of coenzymes in the regulation of metabolic processes, but do not provide energy or serve as building units; and are present in natural foodstuffs or are sometimes produced within the body.
SOURCE: MedlinePlus

For each dietary supplement product in the DSLD, the ingredients names are stored into the database as they appear on the label.

A "dietary ingredient" is an ingredient that adds further value to (supplement) the diet. A "dietary ingredient" may be one, or any combination, of the following substances:

• a vitamin
• a mineral
• an herb or other botanical
• an amino acid
• a dietary substance for use by people to supplement the diet by increasing the total dietary intake
• a concentrate, metabolite, constituent, or extract of one of the ingredients listed above

The Dietary Supplement Health and Education Act defines a dietary supplement as containing "dietary ingredients." Examples of dietary ingredients include vitamins, minerals, botanicals, and amino acids. The term "other ingredient" also refers to substances that are not dietary ingredients such as binders, colors, excipients, fillers, flavors, sweeteners, OR are the source of the dietary ingredient.

There are several locations where an ingredient is listed within a label. Ingredients can be listed within the Supplement Facts panel or below (or outside of) the Supplement Facts panel, or elsewhere on the label. Then an ingredient may contain additional information like Source Ingredients, Alternative Names, Blend Ingredients, and etc.

There is a separate table that stores an ingredients synonym or alternative name. This may be identified within the supplement facts label in parentheses immediately following or indented beneath the name of a dietary ingredient.
SOURCE: FDA - 21 CFR 101.36(b)(2)

Example:

Primarily refers to "Proprietary Blend" or other appropriately descriptive term or fanciful name which may be highlighted by bold type. Which lists all of the dietary ingredients it contains in descending order of predominance in a column or linear fashion. On the same line of the Proprietary Blend Name, the total weight is of all the dietary ingredients contained within the blend.

Example: "Avoid leaving in direct sunlight", "keep refrigerated" or "store in a cool, dry place."

Any label statements that assert claims, such as structure/function statements, or assert specific advertising and/or simplified scientific or clinical language related to the dietary supplement product. These statements may also assert the quality of the dietary supplement product, or other customer-specific and manufacturing information.

On the label there may be specific information and an image presented as a formal seal with related language asserting a quality parameter or certification organization associated with the dietary supplement product. The presence of such a seal does not have to be approved by any government agency nor are any assertions that accompany such a seal necessarily verified by a government agency.

These label statements provide information related to the daily amount, timing and other usage instructions for the dietary supplement product.
Example: "SUGGESTED USE: One capsule daily with a meal, as a dietary supplement."

LanguaL™ stands for "Langua aLimentaria" or "language of food." LanguaL™ is a structured, controlled vocabulary for describing foods, in a systematic organization that simplifies retrieval of information for data analysis. It is based on the principle that items within a database (whether they are dietary supplements or conventional food products) can be described by a combination of uniform terms chosen from "facets" that characterize various mutually exclusive attributes of these products. These facets include food groupings, main ingredient source, physical attributes, other ingredients and processing, packaging and packaging materials, dietary uses, and other miscellaneous characteristics.

For product descriptions in the DSLD, "serving size" refers to the total number of units in a single serving as identified in the Supplement Facts Panel. Values must be greater than zero, and must be whole numbers when serving size unit is discrete (e.g., tablets, capsules, softgels), but may contain decimals when serving size unit is measured in non-discrete units (e.g., milliliters, ounces).

In any given product, there may be more than one serving size or a range of servings per container on the label if the product is formulated and specified for more than one age, gender, or life stage group. When defining serving size, if there is a range of serving sizes, the highest value will be recorded in the database, and the range will be recorded as a note.

When a label includes multiple serving sizes (e.g, "Serving Size 1 Bottle(s) (18 fl oz)"), then the primary is defined as the one that appears first or at the top-left and the rest would be considered alternates. When an alternative serving size is specified on the label, it gets stored in the text descriptor for the first serving size exactly as it appears on the label.

A description of one serving's form (e.g., tablet, capsule, ml). Specific regulations govern the terms used to describe one serving's form. Also called "serving size declaration."
