'Clean' on a supplement label isn't a legal term. Here's what to look for instead.
At an industry panel, Marc Lobliner (Ketone Labs) and Karen Hecht, PhD (AstaReal) agreed that "clean" has no legal definition. Hecht called it "a marketing term. It's not a legal term." The panel said real quality comes down to label accuracy, banned-substance testing and research on the actual product. (Nutritional Outlook (Sept 30, 2026))
"Clean." "Pure." "No junk." Supplement labels love these words, but they don't have a legal definition. 🧐
So instead of trusting the buzzword, look for three things: ✅ Label accuracy: independent testing that the dose matches the label ✅ Contaminant screening: e.g., heavy metals ✅ Banned-substance testing, if you compete in a drug-tested sport
A quality product still has to be the right product for you. A registered dietitian can help you decide what's worth taking.
Visual: A 4-slide carousel. Slide 1: the word "CLEAN" in big type with a magnifying glass and the line "Not a legal term." Slide 2: "What 'clean' should mean" with the three checks. Slide 3: "Competing? Look for banned-substance certification and verify it on the certifier's website." Slide 4: "Quality ≠ need. Ask a dietitian." Use generic or fictional product packaging only.
