About Zinc + Copper
What it is
Two essential minerals often taken together, because high zinc intake can lower copper absorption.
Common forms
Capsules or tablets, often as bisglycinate (for example Albion® chelates).
Typical label doses
Labels in our directory give 25 mg zinc a day, with a smaller amount of copper.
