What TOXN is
TOXN provides reference information about everyday exposure to common substances, compared against published limits from public agencies such as the FDA, EPA, EFSA and ATSDR. Estimates are computed from the answers you provide.
What TOXN is not
TOXN is not a medical device and does not measure anything in your body. Nothing in the app or on this site is medical advice, diagnosis, or treatment. Always talk to a healthcare professional about health concerns, and before making changes if you are pregnant, nursing, or managing a condition.
