Interesting Facts

Cancer protection
Coffee

The World Health Organization cites that there is an overwhelming amount of research that coffee can promote health and actually inhibit cancer. However, they did note that drinking coffee at temperatures in excess of 140 degrees Fahrenheit can increase the risk of cancers of the throat and esophagus. This temperature is much higher than which coffee is typically consumed.

Caution

Caffeine is highly stimulatory and a systemic vasoconstrictor. Caution should be exerted if one is either not used to caffeine ingestion or currently has high blood pressure. Caffeine should not be used as a supplement in those with cardiac impairments without prior consultation of one's doctor. Caffeine can also have an effect on ones quality of sleep; while you may be able to fall asleep, it will be of inferior quality. Chronic ingestion of caffeine reduce performance benefits of caffeine.

Recommended Dosage

Researchers tend to use a dosage range of 4-6mg/kg bodyweight.
