As a result, soluble and insoluble fiber information may be incomplete for some fiber containing products. However, manufacturers may provide this information if they wish. The amounts of soluble and insoluble fiber do not have to be provided. The amount of fiber contained in a ‘serving’ of a dietary supplement must be provided on the Supplement Facts panel of fiber containing supplements. Consequently, fatty acid information for fat containing products may be incomplete. Other classes of fatty acids and individual fatty acids do not have to be provided. Likewise, the total saturated and trans fatty acid content must be listed. The amount of fat contained in a ‘serving’ of a dietary supplement must be provided on the Supplement Facts panel if a product contains fat. As a result, amino acid information for protein containing products may be incomplete.
The individual amino acids in a protein containing supplement may be listed, but inclusion on the Supplement Facts panel is not mandatory. The amount of protein contained in a ‘serving’ of a dietary supplement must be provided on the Supplement Facts panel if a product contains protein. Some examples of nutrients and other supplement components for which completeness may be an issue are as follows: Due to this limitation, the nutrient totals may be under-estimated for some nutrients because the DSAM database does not contain the usual relationships to other nutrients or components. Since NCC does not calculate or impute nutrients for dietary supplements, the level of completeness for some nutrients and components may therefore be low. Most notably, they are not required to list on the Supplement Facts panel all of the nutrients the product contains. Dietary supplement manufacturers have some discretion with respect to the information they provide on this panel. For example, multiply the Synthetic Folate (folic acid) value in Supplements by a factor of 1.7 to convert to Dietary Folate Equivalents in Supplements or divide the Omega-3 Fatty Acids value in Supplements by 1000 to convert from milligrams to grams.Īll nutrient values and other components assigned to dietary supplements in the DSAM database are limited to the information provided on the product’s Supplement Facts panel. It is also important to note that nutrients with different units or descriptions should not be combined unless conversion factors are available (see the Alerts and Footnotes in the pdf). Consequently, total intake estimates from food and dietary supplement sources combined may not be calculated for these nutrients and food components.
For example, the variable ‘chromium’ is included in File 12 but is not available in File 04. Conversely, File 12 contains some nutrients and dietary supplement components that are not included in File 04.
For example, the variable ‘maltose’ is included in File 04 but is not available in File 12. It is important to note that File 04 contains some nutrients and food components that are not included in File 12. Comments are provided to explain the rationale for some of the combinations. A listing of variable names and file locations (column numbers) for nutrients with the same units in File 04 and File 12 are provided herein to assist in this process ( pdf). Nutrients with common units and definitions in File 04 and File 12 may be combined to calculate total intake estimates. Nutrients and Food Components for Which Totals May be Calculated By summing nutrient intake estimates from File 04 and File 12, total daily intake of nutrients from food and supplement sources may be calculated (e.g., vitamin C intake from 24-hour dietary recall record + vitamin C intake from 24-hour dietary supplement recall interview = total vitamin C intake from all sources combined). File 12 includes total daily nutrient intake estimates from the DSAM interview (e.g., total daily vitamin C intake from the 24-hour dietary supplement recall interview). File 04 contains total daily nutrient intake estimates from the 24-hour dietary recall record (e.g., total daily vitamin C intake from the 24-hour dietary recall record). If dietary supplement use was assessed using the Dietary Supplement Assessment Module (DSAM), nutrient intakes from food and dietary supplement sources combined may be calculated using Output File data in File 04 (Intake Properties Totals File) and File 12 (DSAM Total 24-hour Supplement Intake File).
