Another name for caffeine, the stimulating chemical found in guaraná berries and other plants.
From guaraná, a South American plant, combined with the chemical suffix -in. The Guarani indigenous people used guaraná berries for centuries before the term was scientifically named in the 19th century.
Guaranin and caffeine are literally the same molecule—caffeine in your morning coffee is identical to the stimulant Amazonian tribes discovered in guaraná berries thousands of years ago!
