Key Points
Question
Are select dietary supplement products advertised and sold to support or boost the immune system accurately labeled according to the Supplement Facts listed ingredients on product labels?
Findings
This case series study analyzed 30 dietary supplement products purchased from Amazon.com with claims related to immune health. Seventeen of 30 products had inaccurate labels; 13 were misbranded, and 9 had additional components detected but not claimed on the label.
Meaning
Quality control measures seem insufficient for most select dietary supplement products. The public has a right to know that they are buying what is stated on the label.
