Upper-limit caution

The Tolerable Upper Intake Level for Copper is 10 mg per day. Routine intakes above this level — counting food + supplements — raise the risk of adverse effects. Multivitamins, fortified foods, and standalone supplements stack faster than people expect.

How Copper appears on labels

Supplement labels list Copper under several names depending on the chemical form used. Any of these on an ingredients panel counts toward your Copper intake:

  • copper
  • copper bisglycinate
  • copper sulfate
  • copper gluconate
