How Much Earl Grey Is Too Much?

While moderate use of Earl Grey tea is harmless for the majority of people, excessive consumption can have negative effects. Earl Grey, a black tea, mostly mimics the effects of a straightforward black mix. But it also contains bergamot orange oil, which can have further negative effects.

Caffeine Jitters

Earl Grey contains caffeine, a stimulant of the central nervous system. Up to five cups of tea a day are considered a moderate intake, but any more could lead to caffeine intoxication, according to MedlinePlus. Some extremely sensitive persons may experience these symptoms even after consuming only a small amount of this, which can cause anxiety, heart palpitations, tremors, and insomnia. With regular use, you run the risk of developing a caffeine addiction and going through withdrawal when you quit, which can cause headaches and irritability.

Iron Absorption Issues

Tea contains tannic and gallic acids, two substances that prevent the iron in plant meals like beans and green leafy vegetables from being absorbed. According to Marla Reicks, a nutritionist at the University of Minnesota Extension, depending on the amount of these acids in the cup, drinking tea with a meal can reduce the absorption of iron by up to 75%. (which differs depending on the brand, intensity, and steeping time). Drink your Earl Grey in between meals rather than with them to promote optimum iron absorption.

Stained Teeth

Black teas like Earl Grey stain more than green tea and other lighter varieties of tea, and tea tannins can transfer to tooth enamel and stain your smile. As soon as you’re done drinking, rinse your mouth out or brush your teeth to help prevent stains. To help remove plaque, floss every day.

Toxicity of Bergamot

You would risk consuming too much bergamot oil if you consume a lot of Earl Grey tea. According to the Center for Neuromuscular Disease at Washington University, the oil includes a toxin known as bergapten, which can disrupt potassium absorption in specific neurons and cause muscle twitching, hand and leg cramps, itching or burning sensations, pressure in the eyes, or blurred vision. According to the institute, these symptoms usually go away a week after quitting Earl Grey tea. But if you see any of these side symptoms, see your doctor right away for a diagnosis and possible treatments.
