Earl Grey Tea Or Black Tea

Earl Grey tea is a mixture of black tea and bergamot oil (BGO) (1). It has a bold and citrusy flavor due to the addition of synthetic or natural bergamot oil.

Bergamot orange is an aromatic citrus fruit commonly found in the Mediterranean. The taste may vary from one producer to the other. However, in general, its taste is bold and refreshing.

Caffeine Content In Earl Grey Tea

Traditional Earl Grey tea contains caffeine, the exceptions being herbal Earl Grey tea or its decaffeinated variants.

The caffeine content in Earl Grey tea varies depending upon the producer. But, in general, it is almost similar to the amount of caffeine in other black teas.

A regular cup of Earl Grey tea contains approximately 55-65 mg of caffeine (2). Decaffeinated Earl Grey tea contains lesser caffeine.

But, is Earl Grey tea safe to drink while pregnant? Does it have any adverse effects? Read on to find out.

How Safe Is Earl Grey Tea During Pregnancy?

Earl Grey tea is extremely popular. Hence, you will find innumerable flavors in this type of tea. Though tea offers several health benefits, research has shown that too much intake of any form of black tea can lead to serious side effects due to its caffeine content.

Several studies have found that high caffeine intake (>150 mg/day) during pregnancy may result in an increased risk of low birth weight (in the infant), spontaneous abortion, and restricted fetal growth (3), (4), (5).

However, limiting your caffeine intake to 1-2 cups per day is not a cause for concern, even in pregnancy (6).

It is always advisable to consult your doctor before experimenting with any beverages.

Hence, even though Earl Grey tea is soothing in nature, make sure to drink it only in moderation during pregnancy.

How Much Should You Drink?

According to the European Food Safety Authority (EFSA) and the American Institute of Medicine, caffeine intake should be limited to less than 200 mg/day during pregnancy (7).

Health experts say that ingesting around 250 mg of caffeine per day is safe for adults, but only if you are maintaining a healthy lifestyle.

In pregnant women, the ingestion should be restricted to around 150 mg/day.

Drinking too much Earl Grey tea is harmful to the health of the fetus as well as the mother.

So, if you are breastfeeding or are pregnant, you should restrict your consumption to 1-2 cups to avoid complications.

Now, let’s check out the potential side effects of this popular tea in pregnant women.

Possible Side Effects Of Earl Grey Tea In Pregnant Women

The possible side effects of Earl Grey tea in pregnant women include:

  • Headaches
  • Nervousness
  • Sleeplessness
  • Irritability
  • Heartburn
  • Confusion
  • Irregular heart rate
  • Tremors
  • Convulsions

If you have developed a psychological or physiological dependence on this beverage, withdrawal from it can also lead to mental issues.

According to a study conducted in the Netherlands, too much caffeine consumption from tea (>300 mg/day) may lead to pregnancy-induced hypertension (8). However, further research is required to substantiate these claims.


Although you can continue drinking Earl Grey tea during pregnancy, you must restrict your consumption to 1-2 cups per day. You also need to consult your doctor if you are suffering from any other health concerns.

Switching over to decaffeinated black tea is a much better idea to rule out any problems during pregnancy.
