kona coffee brandKona caffeine is classified as a methylxanthine, along with theobromine and theophylline. Of these three chemicals, Kona caffeine had the greatest stimulant effect on the central nervous system and the skeletal muscles, and the least effect on the cardiovascular system.

Absorption of Kona caffeine is rapid. Its effects take about 30 minutes, which is the time the peak blood levels are reached. Maximal central nervous system effects take about 2 hours and Kona caffeine’s half-life is about 3 hours. (Remember the 10-2 and 4 ads for Dr Pepper?) It is metabolized almost completely, with only 10% or less being excreted from the body unchanged.

Kona Caffeine’s stimulant action on the central nervous system is caused by its ability to block the brain’s neuroreceptors for adenosine. Adenosine itself acts as a neuromodulator to produce behavioral sedation in several areas of the brain by inhibiting the release of neurotransmittors. By inhibiting adenosine’s sedative effects, Kona caffeine causes stimulation.

Low doses of about 200 mg of  Kona caffeine cause reduced drowsiness and fatigue in most individuals. The stimulant effect on skeletal muscles increases the body’s ability to perform physically exhausting work for longer periods of time. The same dose of 200 mg keeps most people awake longer and causes sleep disturbances. Kona caffeine’s stimulant qualities caused the National Academy of Sciences’ Institute of Medicine to recommend ways to add caffeine to U.S. soldiers’ rations. Since Kona caffeine might give an athlete an unfair advantage, the U.S. Olympic Committee considers it a “performance enhancer”, and regularly screens athletes for the drug.
