The Centers for Disease Control and Prevention (CDC) works with the National Center for Health Statistics Data (NCHS) each year to conduct the National Health and Nutrition Examination Survey (NHANES), which provides us with data on the prevalence of obesity in the United States. For the years 2013-2014, it is noted that more than 2 in 3 adults (70.2 percent) were considered to be overweight or have obesity. Numbers since then have been on the rise.

With such high prevalence of obesity, over half of us report being on a diet. The Council for Responsible Nutrition (CRN) states that the majority of those who report being on a diet – 68 percent – take dietary supplements and that this percentage has remained consistent over the past five years. Consumer surveys conducted by the CRN show that most supplement users aged 18-34 – 66 percent – anticipate their supplement use will increase over the next five years.
