Some of you may already know guarana as an ingredient in some energy drinks. It contains not only caffeine, but also theophylline and theobromine.
Paullinia cupana can grow up to 3 meters tall as a shrub or, as a variant, Paullinia cupana var. sorbilis, can grow up to 12 meters long in the form of lianas and is native to the Amazon. The plant belongs to the soapberry family and was named after the indigenous Guaraní people. When the guarana capsules are ripe, they burst open and, due to the coloring of the inside of the shell and seeds, are reminiscent of eyes, around which Guaraní myths and legends revolve.
The seeds are harvested, fermented and roasted before they are ground and possibly further processed..
Uses of Guaraná
In addition to the ingredients already mentioned, the seeds contain tannins, proanthocyanidins and catechins. However, the caffeine is of primary interest to the economy.
The caffeine content is up to four times higher than in coffee and ten times higher than in tea, which is why it is often used in energy drinks and for stimulation. Guarana is therefore considered a Nootropic and is said to enhance cognitive abilities. It is assumed that the caffeine in guarana is gentler on the stomach and is released more slowly than caffeine in coffee or tea. People who cannot tolerate coffee seem to tolerate guarana well. However, there are still no precise studies on this.
In recent decades, there have been some investigations and studies on guarana and its effects on human health. There is said to be evidence that guarana seeds can have a stimulating, anti-inflammatory, antioxidant, anti-cancer, cholesterol-lowering and anti-obesity effect..
Due to its performance enhancement and potential support for fat burning, guarana is also important in the area of supplements for athletes.
Important Information
Guarana is not considered a novel food, but does contain caffeine, which must be declared.
The EFSA (European Food Safety Authority) recommends a maximum intake of 400mg of caffeine per day for adults, or a maximum dose of 200mg per intake of a caffeinated drink or food/food supplement. These amounts are not recommended for pregnant women or shortly before intense physical exertion.
If caffeine is ingested in the evening, it can have a negative impact on sleep quality and therefore on performance and stress levels.
By the way: Due to the active ingredients (specifically caffeine and theobromine) we do not recomment for Guarana to be given to animals of any kind.
