Unless otherwise indicated, values are means. The unweighted estimates are reported at the product level for select product types, and represent the percentage of all products reported at the population level obtained from analytic sample 1 that have complete information for the NHANES matching code variables. DS, dietary supplement; DSMQ, Dietary Supplement and Prescription Medication Questionnaire; m, number (unweighted) of “mentions” of each product; MM, multimineral; MV, multivitamin; MVM, multivitamin-mineral; 24HR, 24-h dietary recall.
A generic match indicates that information on both the nutrient and dose of the DS are present, but the product name may be incomplete. NHANES protocol requires an automatic declaration of a generic match for any DS product sold in <25 states, regardless of whether or not an exact match was available.
MVMs are categorized as DSs containing ≥3 vitamins and ≥1 mineral.
MVs and MMs are categorized as non-MVM DS products containing ≥2 vitamins or minerals, respectively.
Calcium and vitamin D are categorized as non-MVM DS products containing calcium and vitamin D, which may contain other vitamins/minerals.
