Theacrine is a naturally occurring chemical that is similar to caffeine. It is found in different types of tea and coffee, as well as in the seeds of the Herrania and Theocrama plant species. People take theacrine by mouth for aging, the common cold, fatigue, and mental performance. Theacrine is also added to pre-workout supplements promoted for improving athletic performance. Theacrine stimulates the central nervous system at higher doses and decreases central nervous system activity at lower doses. Theacrine might also lessen liver damage caused by stress and reduce pain and swelling.
