Guarana is a natural source of caffeine derived from the seeds of the Guarana Paullinia cupana plant, which is native to South America.

The native people in the Amazon region of South America have been using it for centuries as a way to boost energy, but this herb gained popularity in the west after it was added to soft drinks and energy drinks.

Guarana Seed's Caffeine

Guarana seeds contain 3.6% -5.8% caffeine by weight (src.), so if we take the average of that range (4.7%) then 1 gram (1000mg) of guarana seeds would contain on average 47mg of caffeine.

Guarana Extract

Guarana extract is a concentrated form of guarana caffeine. In this case guarana seeds are processed to remove the caffeine they contain.

Many guarana based products contain guarana extract and not whole or ground guarana seeds, which boosts the caffeine content.
