Guarana Seed Powder

Guarana Seed Powder

Guarana is an evergreen sprawling shrub-like vine which grows in the lush Amazon region of South America. The guarana tree produces a red berry that has been used for thousands of years by the natives of the Brazilian Rainforest. They would dry and roast the seeds of the guarana berry, mixing them with water to create a paste that was used like chocolate. The paste was added to food, drinks and medicinal tonics. The active ingredient in guarana is called guaranine which is chemically very similar to caffeine. Guaranine is marketed today to Western consumers in popular energy drinks.

Traditionally used to support healthy bowels, native cultures found that Guarana Seeds could also be used to stimulate mental alertness and support a healthy appetite. The guarana tree is actually named after the Guarani Indians, a South American tribe who used it to support a healthy digestive system and support healthy stamina and physical endurance levels. Guarana drinks are still extremely popular in Brazilian culture. Many people take it daily as a health tonics to possibly relieve heat exhaustion, support healthy aging and healthy detoxification in the body. Guarana soda is actually Brazil's national beverage!

One of the active ingredients in non-GMO Guarana is called guaranine. Today, guaranine is marketed to Western consumers in popular energy drinks. Some research claims that guaranine actually is caffeine. However, there are beneficial antioxidants in guaranine that are not found in other caffeine sources. Guarana is the largest provider of caffeine found in nature containing around seven percent more caffeine than other plants and close to two and a half times the amount of caffeine found in coffee. The main difference in the caffeine found in guarana comes from the way it is released into the body. Guaranine is not water soluble and therefore is released into the bloodstream at a much slower rate, providing a longer sustained effect as a stimulant. Guarana slows down digestion, keeping food in the stomach longer, which may promote feelings of fullness. Guarana may also be beneficial to the heart and may support healthy blood pressure levels.
