CRN members: Responsible is our middle name.

74% of U.S. adults take dietary supplements, according to CRN's 2023 consumer survey. Dietary supplement products include vitamins, minerals, botanicals, sports nutrition supplements, weight management products and specialty supplements. These products are intended to be used as supplements to, not substitutes for, a well-balanced diet and a healthy lifestyle. When used properly, they help promote overall good health. Learn more.

Investing in wellness through supplementation can save billions in disease prevention. According to the CRN Foundation's Supplements to Savings report from Frost & Sullivan, use of certain dietary supplement ingredients by specific populations can reduce the direct and indirect medical costs associated with several chronic diseases and conditions—coronary artery disease, osteoporosis, age-related macular degeneration, cognitive decline, irritable bowel syndrome, and childhood cognitive development disorders.
