Guarana Seed Extract 2.5% Caffeine
Guarana Seed Extract Function
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 it.
