Can You Take Calcium and Humic Acid Together?

May affect absorption

The short answer

Humic Acid can chelate calcium due to its polyelectrolyte nature. This may alter calcium absorption when taken simultaneously.

How to arrange timing

Consider separating humic acid and calcium by 2 hours.

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.
