Guaranine is almost identical in chemical structure to caffeine and has many of the same effects.
The major active constituent is caffeine (sometimes called guaranine to make you think it is different in some way) and similar alkaloids such as theobromine and theophylline (which are also found in coffee and tea).
Since the guaranine is released slowly, the energy boost that is experienced from guarana is not like that of coffee with its sudden rush and quick drop-off.
A cup of guarana, prepared by adding 1-2 grams of crushed seed or resin to 250 ml (1 cup) of water and boiling for ten minutes, can be drunk three times per day.
Other, less commonly used, sources of caffeine include the plants yerba mate and guaraná, which are sometimes used in the preparation of teas and, more recently, energy drinks.

The major active constituent is caffeine (sometimes called guaranine to make you think its different in some way) and similar alkaloids such as theobromine and theophylline (which are also found in coffee and tea).
For example, about 150mg of ephedrine per day can increase metabolic rate by 3-5% over a 24-hour period, whereas a lower dose of ephedrine (60mg/day) increases daily caloric expenditure by nearly 8% when combined with caffeine (200-400mg/day) and aspirin (80-160mg/day of salicin).
Guarana seed powder contains not less than 4% of the alkaloidcaffeine (as guaranine) and therefore the general drug interaction for caffeine should be considered.
Guarana contains guaranine, a compound almost identical to caffeine.
The guaranine is released slowly, over as much as 6 hours time, so the energy boost that is experienced from Guarana is not like that of coffee with its sudden rush and quick drop-off.
Whereas caffeine provides a short lived energy burst that overheats and excites the body, guaranine has a cooling action that revitalizes and relaxes.
Contraindications: Guaranine effects the body in the same manner as caffeine.
Individuals with conditions that may be complicated by high caffeine intake (including insomnia, depression, and pregnancy) should speak with a health professional before adding guarana to their diet.
The seeds contain approximately 3-5% of guaranine (similar to caffeine) and are often crushed and dried by South American natives and used as a stimulating drink.
Due to guaranine effects, some people could experience similar caffeine-like symptoms such as insomnia, trembling, palpitations and urinary frequency.

This means that, when ingested, the body does not quickly absorb it and guaranine is released slowly, over as much as 6 hours, so the energy boost that is experienced from Guarana is not like that of coffee with its sudden rush and quick crash.
Whereas caffeine provides a short lived energy burst that overheats and excites the body, guaranine has a cooling action that revitalises and relaxes.
It is also known to help recovery from hangovers, provide pain relief, reduce fatigue, enhance physical and mental performance, and suppress the appetite to promote weight loss.
It came to be employed in the treatment of migraine and nervous headaches, neuralgia, paralysis, urinary tract irritation, and other ailments, as well as continuing to be administered for chronic diarrhea.
Caffeine may have adverse effects on the blood vessels and other body systems as well as on a developing fetus, and presumably guaranine would have similar effects, but this has not yet been proven.
One of the main ingredients in guarana extract is a form of caffeine called guaranine.
Unlike caffeine, guaranine is slow to release and doesn’t give the initial quick burst of energy and then the quick let-down.
Since the seed is fatty and not water-soluble, it is not quick to absorb in the body so the energy boost will escalate over a number of hours instead of all at once.
It also has a history of use in treating hangovers from alcohol abuse and headaches related to menstruation.
Active constituents: Guaranine (which is nearly identical to caffeine) and the closely related alkaloidstheobromine and theophylline make up the primary active agents in guaraná.
A cup of guaraná, prepared by adding 1-2 grams of crushed seed or resin to 250 ml (1 cup) of water and boiling for ten minutes, can be drunk three times per day.
