Does theacrine have caffeine in it?
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]. 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.The two prominent theacrine-containing foods in the human diet are the fruits and seeds of Theobroma grandiflorum (cupuaçu) and kucha green tea from the leaves of Camellia kucha (Camellia assamica var.Theacrine is a purine alkaloid found in Camellia kucha Hung T. Chang (a wild tea plant species, formerly named as Camellia assamica var. H-purine-2,6,8(3H,7H,9H)-trione, with chemical formula C9H12N4O3 and molecular weight 224. Figure 1).
Does theacrine give you energy?
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. 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.Animal model research has evaluated the toxicity of theacrine and determined it is safe for ingestion [4] and has not been shown to have any negative effects on heart rate and blood pressure in rats [5].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.Theacrine speeds up the central nervous system at higher doses and slows down the central nervous system at lower doses. People use theacrine for fatigue, memory and thinking skills, athletic performance, muscle strength, and many other purposes, but there is no good scientific evidence to support these uses.
What is similar to theacrine?
Dynamine® for Fast Acting Energy Dynamine® is methylliberine, a purine alkaloid found in the Kucha tea leaf. Its molecular structure is similar to Teacrine® and is believed to behave in similar ways in the body. Conclusions. These findings support the clinical safety and non-habituating neuro-energetic effects of TeaCrine® supplementation over 8 weeks of daily use (up to 300 mg/day). Moreover, there was no evidence of a tachyphylactic response that is typical of neuroactive agents such as caffeine and other stimulants.It also doesn’t come with habituation, the onset of tolerance, anxiety, jittery feelings, or the dreaded energy crash. TeaCrine ®’s half-life is ~20 hours, meaning its effects are incredibly long-lasting which is excellent for providing sustained energy, focus, and mood-enhancement, while not impacting sleep.Caffeine: Found in coffee and tea, caffeine boosts alertness and increases dopaminergic activity. L-theanine: An amino acid in green tea that enhances cognitive performance and promotes relaxation. Tyrosine: A precursor substance necessary for producing dopamine, involved in memory formation and emotional regulation.As previously stated, Dynamine™ provides fast acting energy with a shorter half-life, while TeaCrine® provides long-lasting energy with a longer half-life. As they are so chemically similar, when taken alongside caffeine, the effects are really noticeable.
Does theacrine affect sleep?
Perceptions of sleep and arousal were largely unaffected by the consumption of theacrine. Participants perceived a significantly longer sleep onset latency when consuming the 400 mg dose of theacrine 12 h prior to bedtime compared to the placebo, despite no significant effect when assessed objectively. Theacrine might cause sleepiness and slowed breathing at low doses. At high doses, theacrine might decrease sleepiness. Some medications, called sedatives, can cause sleepiness and slowed breathing. Taking theacrine with sedative medications might increase or decrease the effects of those medications.
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. The present findings indicate that both 300 mg of caffeine and a combination of 150 mg of caffeine with 150 mg of theacrine (CTC) significantly enhance cognitive performance, both before and after physically fatiguing exercise in a tactical population.
