Many women have caffeine during pregnancy. And in small amounts, caffeine is safe for the baby. It's a good idea to keep your caffeine intake below 300 mg a day. Limiting your caffeine intake is important because:
- More caffeine may be connected to a higher rate of miscarriage. There is not enough evidence to know for sure.footnote 1
- Caffeine is a diuretic, meaning it makes you urinate more often. This can cause you to lose important minerals, including calcium.
- Caffeine can interfere with sleep for both you and your fetus.
Avoid caffeine, or limit your intake to about 2 cups [500 mL (16 fl oz)] of coffee or tea each day.
Caffeine can be found in many types of drinks and in chocolate. The amount of caffeine in your coffee or tea can depend on the serving size, the brand, or how it was brewed.
- Coffee drinks such as a 500 mL (16 fl oz) mocha can have 175 mg of caffeine, and a 375 ml (12 fl oz) regular coffee can have as much as 260 mg of caffeine.
- Tea can have 30 mg to 130 mg of caffeine in a 375 ml (12 fl oz) cup.
- 30 grams (1 ounce) of milk chocolate can have 1 mg to 15 mg of caffeine, and dark chocolate can have 5 mg to 35 mg of caffeine.
- Many soft drinks and energy drinks also have caffeine.
It is important to keep track of your caffeine intake throughout the day. Check the label if you do not know how much caffeine is in your drink or chocolate bar. Talk to your doctor about caffeine and nutrition during pregnancy.
