What is guaraná?
Guaraná (Paullinia cupana) is a climbing plant from the Amazon region. Its seeds are dried and ground into powder. In Brazil guaraná is known mainly as a soft drink, in Germany rather as powder, capsule or ingredient in energy products. The seed contains caffeine (formerly also called “guaranine”) – chemically the same substance as in coffee.
Putting caffeine in perspective
By weight, the caffeine content of guaraná seeds is considerably higher than that of coffee beans. How much you take in per serving, however, depends on the amount used and on the product. A cup of filter coffee contains roughly 60–100 mg of caffeine.
As a guideline for healthy adults, the European Food Safety Authority (EFSA) states: up to 400 mg caffeine per day from all sources, single servings up to about 200 mg; for pregnant women about 200 mg per day. Coffee, tea, mate, cola and energy drinks all count.

What to look for when buying
- Ingredient list: For powder, only “guaraná” (seeds) should be listed.
- Caffeine information: Is there a figure per serving? If not, be cautious in your estimate.
- Origin and organic: Information on origin and certification builds trust but does not replace a lab analysis.
- Marketing claims: Statements such as “strengthens”, “heals” or “detoxifies” are only permitted to a limited extent for foods in the EU – be sceptical.
Everyday use
Powder can be stirred into smoothies, yoghurt or drinks. Because of the bitter taste it goes well with banana, berries and cocoa. Start with a small amount and keep track of how much caffeine you already consume during the day.
Do not use late in the evening if you are sensitive to caffeine – sleep problems are common.
Who should be careful
- Pregnant and breastfeeding women
- Children and teenagers
- People with heart rhythm disorders, high blood pressure, anxiety disorders or sleep problems
- People taking medication that can interact with caffeine
If you get palpitations, trembling or strong restlessness: stop using it and, if necessary, seek medical advice.

Frequently asked questions
Is guaraná stronger than coffee?
Per gram, the seed contains more caffeine. What matters, though, is the serving size: depending on the product, a few grams of powder can contain a similar amount to a cup of coffee. The manufacturer's information is what counts.
Can I combine guaraná with coffee?
The caffeine adds up. If you drink a lot of coffee, you quickly exceed recommended amounts.
Is the Brazilian guaraná drink the same thing?
No. It is a soft drink with guaraná flavouring or extract, usually sweetened; the amount of caffeine is product-specific.
