Each half gram capsule contains 250 milligrams of caffeine. These capsules are filled by hand with a manual machine, not with a high speed automatic machine, and thus, only pure herbal extracts are in the capsules. Capsules produced with high speed machines in herbal remedy and vitamin "factories" contain several other ingredients, including preservatives because so many bottles of product are produced at one time, and lubricants to ensure that the machines will run faster and more efficiently. Check their label! Also, Barlowe's Herbal Elixirs is one of the very few manufacturers that still pack their products in glass whenever possible, even though glass is more expensive.  Barlowe believes that chemicals can leach out of plastic containers and contaminate the contents, and that the use of glass is much better for the environment. Guarana is an herbal stimulant that contains a form of caffeine called "guaranine". Guaranine is two and a half times stronger than the caffeine generally found in coffee, tea and soft drinks, and it is unique because it is released in the body at a much slower rate due to the fact that certain fats in the guarana powder act as a natural "time-release" formula. Since the Guaranine is released slowly, users do not experience a sudden rush and quick drop-off like they do with coffee. Instead, Guarana provides stimulation that tends to escalate over several hours. Guarana acts as an appetite suppressant and yields a temporary increase in body temperature and metabolic rate, thus making it quite effective in the support of weight loss programs. Guarana also increases mental alertness, fights fatigue, and increases physical endurance. Studies have shown that Guarana enhances memory. In Brazil, Guarana is taken daily as a health tonic by millions of people. There, it is utilized to overcome heat fatigue, to detoxify the blood, and to combat obesity. In body care products,  it has been found to tonify the body and help in the treatment of cellulite.
