Extract - Guarana side effects
Guarana is an herbal stimulant that contains a form
of caffeine called guaranine, which is 2.5 times stronger than the
caffeine found in coffee, tea and soft drinks. What makes guaranine
unique from caffeine found in beverages is its slower release. That's
because the guarana seed is fatty (even in powder form) and is not
readily water-soluble. Therefore the body does not quickly absorb
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. Rather, it continues to
escalate over hours.
While caffeine from beverages provides a short-lived
energy burst that overheats and excites the body, guaranine has
a cooling action that revitalizes and relaxes. This is because guarana
contains other components that modify the activity of this substance.
The end result is more beneficial to the body than tea or coffee.
Caffeine accelerates the effectiveness of CLA, thus
making CLA a more potent fat burner. Guarana has been shown to stimulate
the migration of lipids so fat can be burned as energy. It is also
an appetite suppressant.
Guarana aids in a temporary, natural increase in
body temperature and metabolic thermogenesis through nutritional
stimulation of the body's ß receptor pathway, which can induce
the breakdown and release of stored body fat, thereby allowing stored
fats to be turned into energy.
Thermogenesis refers to the body's production of
heat, a normal part of metabolic processes. Thermogenesis can be
enhanced by certain nutritional substances. When stimulated through
appropriate dietary supplementation, thermogenesis is also a mechanism
that increases metabolic rate. Stored body fat, if released and
available for use, can provide the fuel for this increased metabolic
rate. Other active constituents of guarana are theobromine and theophylline,
which are called xanthines (a class of thermogenic substances found
in coffee, tea and certain beans). They have some effect on increasing
metabolic rate, suppressing appetite and enhancing both physical
and mental performance. They also act as muscle relaxants and possess
Guarana increases mental alertness, fights fatigue,
and increases stamina and physical endurance. Native to Brazil,
guarana is taken daily as a health tonic by millions of Brazilians.
It is reported to help overcome heat fatigue, detoxify the blood
and is useful for flatulence and obesity. In body care products,
it has been used for its tonifying and astringent properties, and
in the treatment of cellulite.
