What food should I take copper bisglycinate with?

Last reviewed: May 2026

The short answer

Protein-rich meals are ideal, since amino acids can further support mineral absorption. If you're looking to boost copper intake through food alongside supplementation, oysters are by far the highest natural food source of copper, followed by organ meats, nuts, seeds, and dark chocolate.

Why protein pairs well

Copper bisglycinate is already chelated to the amino acid glycine, so it doesn't require food for tolerability. But taking it with a protein-containing meal is a reasonable choice: protein digestion releases amino acids that can support mineral uptake, and food is comfortable for anyone with a sensitive stomach.

Copper-rich foods worth knowing

Oysters and other shellfish (the richest common source)
Organ meats, especially beef liver
Nuts and seeds (cashews, sesame, sunflower)
Dark chocolate and cocoa
Whole grains and beans

What to avoid pairing it with

Don't take copper at the same time as high-zinc or high-iron foods or supplements — those minerals compete with copper for absorption. Space them a few hours apart. See what not to take with copper bisglycinate.
