NSF Voices Support for FDA Guidance on Highly Concentrated Caffeine in Supplements

ANN ARBOR, Mich. – NSF applauds the U.S. FDA’s decision to protect consumers from highly concentrated caffeine.

“NSF recognizes caffeine as a legitimate public health concern, which is why NSF/ANSI 173, the American National Standard for dietary supplements, includes strict labeling requirements and limits on the amount of caffeine that NSF certified supplements can contain,” said Lori Bestervelt, Executive Vice President and Chief Technical Officer at NSF.

Consumers can take NSF certified supplements with confidence. In addition to caffeine limits and labeling requirements, NSF certification also requires:

  • Verification of the Good Manufacturing Practices (GMPs)
  • Label claims review to verify what’s on the label is what’s in the package
  • Toxicology review to verify product formulation and label claims
  • Contaminant testing to ensure the product does not contain harmful levels of specific contaminants like lead and arsenic
  • Ongoing monitoring to verify compliance through periodic audits and tests
