USP Verified Dietary Ingredients

USP verifies dietary ingredients used in the manufacture of dietary supplements, including:

  • Amino acids
  • Botanical extracts
  • Nonbotanicals
  • Vitamins
  • Minerals

Participation in USP's Dietary Ingredient Verification is voluntary and open to manufacturers of ingredients marketed for use in the dietary supplement industry worldwide. USP awards use of the USP Verified Ingredient Mark and issues a verification certificate for ingredients that meet its rigorous program requirements.

The USP Dietary Ingredient Mark & What It Means

Manufacturers of dietary ingredients that pass USP Verification can display the USP Verified Ingredient Mark on containers of verified products, as well as on an accompanying Certificate of Analysis. When the manufacturers of dietary supplement finished products see this distinctive mark on the containers of ingredients they buy, they can feel confident that

  • The ingredients are consistent in quality from batch to batch.
  • The ingredients meet label or certificate of analysis claims for identity, strength, purity, and quality.
  • The ingredients are prepared in accordance with accepted manufacturing practices.
  • The ingredients meet requirements for acceptable limits of contamination.
