Can you drink guarana while pregnant?
Not advisedNo, skip guarana during pregnancy. Guarana seed is one of the most concentrated caffeine sources there is, and the drinks and supplements that contain it rarely tell you how much caffeine you are actually swallowing.
Why
The concern is caffeine, plain and simple. ACOG puts the pregnancy ceiling at 200 mg of caffeine a day, and guarana seed carries several times more caffeine by weight than coffee bean, so a single energy drink or guarana capsule can blow past that limit on its own. The NHS also flags that caffeine in pregnancy adds up across everything you drink, and guarana is usually hidden inside energy drinks alongside more caffeine from other ingredients, which makes it almost impossible to count. Leave it out and spend your 200 mg on something you can actually measure.
Safer alternatives
- one 8 oz brewed coffee, which keeps you inside the 200 mg daily limit
- a decaf iced latte
- chilled rooibos or peppermint tea
- sparkling water with lime and a pinch of salt for an afternoon lift

Frequently asked questions
I drank a guarana energy drink before I knew I was pregnant. Is that a problem?
One drink is very unlikely to have caused harm. The 200 mg figure is a daily average to aim for, not a threshold where damage starts, and plenty of women have a few caffeinated drinks before they find out. Switch to counting your caffeine from today.
What about Brazilian guarana soda, is that as strong?
Guaraná sodas are far weaker than energy drinks or extracts, usually in the same range as a cola. A can still counts toward your 200 mg, so treat it as roughly a third of a cup of coffee and keep track across the day.
Is guarana in a pre workout or weight loss supplement safe?
No, those are the versions to leave alone. Supplements use concentrated guarana extract, the dose is often undeclared, and they typically stack it with added caffeine and other stimulants. There is no way to keep yourself under the ACOG limit when the label does not give you a number.
