Guarana is a Brazilian plant native to the Amazon basin, which contains an impressive range of stimulants, such as caffeine, theophylline, and theobromine.

Guarana is also commonly known for its ability to reduce fatigue, boost energy, and aid learning and memory. It has also been linked to better heart health, weight loss, pain relief, healthier skin, lower cancer risk, and a decreased risk of age-related eye diseases.
