Can You Take Calcium and Colloidal Gold Together?

May affect absorption

The short answer

Colloidal gold nanoparticles can aggregate with divalent cations such as calcium in the GI tract, potentially reducing the bioavailability of both supplements.

How to arrange timing

Separate colloidal gold and calcium supplements by at least 1 hour to minimize potential aggregation 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.
