Is theacrine like caffeine?
Theacrine (1,3,7,9-tetramethyluric-acid) is a pure alkaloid with a similar structure to caffeine and acts comparably as an adenosine receptor antagonist. Early studies have shown non-habituating effects, including increases in energy and focus in response to Teacrine®, the compound containing pure theacrine. Theacrine (1,3,7,9-tetramethyluric acid) is a lesser-known purine alkaloid that is structurally similar to caffeine. It was first discovered in Camellia assamica var. Yunnan Province of China.Theacrine is structurally similar to caffeine (Figure 2), but in fact its physiological effects are quite different from the latter. Theacrine is shown to be stimulatory when used in higher doses, however, it can actually have a sedative effect when used in low doses such as the amount consumed through tea leaves of C.Theacrine is a specific purine alkaloid in Kucha and no or little theacrine was detected in the leaf of Camellia sinensis which is usually used for processing green tea or black tea. Both theacrine and caffeine are detected in leaf of C.Theacrine (1,3,7,9-tetramethyluric acid) is another possible non-caffeine supplement to improve egamer performance. Theacrine is a pure alkaloid isolated from the Kucha tea leaf and other plant species, and, like caffeine, is an adenosine receptor antagonist and activates dopamine D1 and D2 receptors [22,23].
Does theacrine cause anxiety?
The same study included data for a group of six subjects who were dosed 100, 200, or 400 mg of theacrine over a seven-day period where they noted moderate to large effect sizes for energy, fatigue, concentration, anxiety, motivation to exercise, and libido with the 200 mg dose [8]. The consumption of theacrine had no significant impact on objective sleep compared to placebo. There was a small, non-significant increase in wake after sleep onset of ~ 20 min and reduction in sleep efficiency of ~ 5% at each timepoint of consumption for the 400 mg dose of theacrine.
Does theacrine increase blood pressure?
Like caffeine, theacrine stimulates the central nervous system at higher doses and decreases central nervous system activity at lower doses. But unlike caffeine, theacrine does not seem to affect blood pressure. Theacrine might also lessen liver damage caused by stress and reduce pain and swelling. Both caffeine and Theacrine can fuel your day but they do so differently. Caffeine delivers fast energy with potential side effects, while Theacrine offers a cleaner, longer-lasting boost with fewer jitters. Depending on your needs, one might suit you better—or you might benefit from using both accordingly.Like caffeine, theacrine stimulates the central nervous system at higher doses and decreases central nervous system activity at lower doses.

Is theacrine safe to use?
When taken by mouth: Theacrine is possibly safe when used short-term. A specific product (TeaCrine) providing 300 mg of theacrine daily has been used safely for up to 8 weeks. It seems to be well-tolerated, but it’s not clear what side effects theacrine might cause. Daily intake of up to 300 mg of theacrine across eight weeks had no negative effect on blood pressure, heart rate, electrocardiogram indicators of cardiac function, or blood safety markers in sixty healthy adults14.
What does theacrine feel like?
The dopamine difference for theacrine was illustrated by a human study of 200mg theacrine that increased feelings of energy, motivation to train, willingness to exercise, and concentration vs. Ziegenfuss 2017). No changes in heart rate or blood pressure were noted – something very unlike caffeine. Both caffeine and Theacrine can fuel your day but they do so differently. Caffeine delivers fast energy with potential side effects, while Theacrine offers a cleaner, longer-lasting boost with fewer jitters. Depending on your needs, one might suit you better—or you might benefit from using both accordingly.
