Supplement Facts Panels: The Label Rules That Trip Up New Brands
Supplement Facts panel rules that trip up new brands: outdated IU units, Daily-Value rounding, and proprietary-blend errors that draw FDA warning letters.
What You Can and Can’t Say on a Supplement Label: Structure/Function vs Disease Claims
‘Supports’ you can say. ‘Treats’ turns your supplement into a drug. The structure/function vs disease-claim line, and what belongs on your label.
Proposition 65 for Supplement Brands: Warnings, Testing, and Risk
Prop 65 is a California warning law enforced by private plaintiffs, not a purity limit. When a supplement warning is required, and how testing decides it.
New Dietary Ingredients: When Your Supplement Needs an NDI Notification
An ingredient not marketed before October 15, 1994 can trigger a 75-day FDA notification. How to tell whether yours is a new dietary ingredient. Early.
‘FDA-Registered’ vs ‘FDA-Approved’: What a Supplement Brand Can and Can’t Say
