Can You Take Colloidal Silver and Selenium Together?

May affect absorption

The short answer

Silver ions form insoluble silver selenide complexes with selenium, reducing the bioavailability of both minerals. This interaction is well-documented in toxicological literature.

How to arrange timing

Separate colloidal silver and selenium supplements by at least 2 hours to avoid the formation of insoluble silver selenide in the GI tract.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
