Abstract:
|
The goal of the study was to generate national level estimates of the nutrient content of average daily dose of adult multivitamin minerals (AMVM) sold in the United States from a representative sample of the products from each of the groups: 1. For the top 16 brands, the objective was to obtain estimates of the nutrient content for 35 of the most important products. This group accounts for approximately 86% of the total market-share of all AMVM. 2. For the next 12 brands, the objective was to obtain estimates of the nutrient content for the most representative product. This group accounts for approximately 7% of total market-share. 3. For all other brands, the objective was to obtain estimates of the nutrient content for a sample of 15 statistically representative products/brands. The total marketing share for the 77 brands in this group was approximately 7%.
