Can You Take Calcium and Strophanthus Together?

Use extra care with this pair

The short answer

Strophanthus contains cardiac glycosides (ouabain). Elevated calcium levels can potentiate cardiac glycoside toxicity, increasing risk of arrhythmias.

How to arrange timing

Avoid combining Strophanthus with calcium supplements. Cardiac glycosides and calcium have a well-documented interaction.
