Testing & Certifications Explained

Thompson does not appear to have any third-party testing certifications. This means that no independent organization has verified the quality, purity, or potency of their products. Consumers should be aware that the absence of certifications like USP, NSF, or Informed-Sport means there is no guarantee that the ingredients listed on the label are accurate or that the product is free from contaminants.

How Thompson Compares

Another competitor, Puritan's Pride (Trust Score 40/100), has a lower trust score than Thompson, but still provides more information on product testing.
