01 Oct 2019 --- Dietary supplements usage in the US has peaked at an “all-time high,” with 77 percent of US adults reporting they consume dietary supplements. This is according to the Council of Responsible Nutrition (CRN) 2019 Consumer Survey on Dietary Supplements. In line with CRN surveys from previous years, the report found that the majority of US adults, both male and female aged 18 and above, take supplements. This available-for-purchase consumer survey reaffirms the vital role supplementation plays in the lives of most US Americans, says CRN.
