Theacrine, also known by the branded name TeaCrine, is a purine alkaloid found naturally in certain plants, most notably the *Camellia assamica* var. *kucha* tea plant. Structurally, it is very similar to caffeine, differing by only one methyl group (NIH ODS). Interest in theacrine stems from its potential to exert stimulant-like effects without some of the common drawbacks associated with high caffeine intake, such as jitters or tolerance development over time.
While caffeine has been extensively studied, research into theacrine is more recent and ongoing. It is often marketed as a nootropic or ergogenic aid, particularly in supplements aimed at enhancing energy, focus, and athletic performance. The compound's longer half-life compared to caffeine also suggests a more sustained effect (Examine.com). Anecdotally, users report a smoother energy curve with less of a 'crash' sensation than with caffeine alone. Theacrine is typically consumed orally as a dietary supplement.
