Q. You briefly mentioned Earl Grey tea causing leg cramps. You suggested oil of bergamot used for flavoring can interfere with potassium absorption.
Eliminating the tea was an instant cure for a persistent problem with muscle cramps. I just wanted you to know.
A. Earl Grey tea gets its distinctive flavor from the citrus fruit bergamot. The oil contains a natural compound called bergapten that can interfere with the flow of potassium into and out of cells. This is presumed to be the reason that too much Earl Grey tea can cause muscle cramps in susceptible people (The Lancet, April 27, 2002). We’re glad you were able to conquer your muscle cramps by giving up the tea.
