What are the side effects of theacrine?
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. 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.
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]. 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.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.
Is theacrine bad?
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]. 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.Animal toxicology testing has been performed on theacrine, and no toxic or adverse effects were found at standard doses. A human study of a branded form of theacrine known as TeaCrine® found that supplementing with up to 300 mg daily for more than eight weeks is considered clinically safe and not habit-forming.Studies indicate it is safe and works well on its own, but is even better in a stack with caffeine and TeaCrine. The optimal dosage range lies in the 50-150mg range, taken about 30 minutes prior to exercise. Has few side effects and very limited medication interactions.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.
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. It’s not just energy we’re talking about, either. TeaCrine® also provides that powerful dopamine activation for motivation and sensory experience not found in most anti-stress formulas.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.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.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.
What foods have theacrine?
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).TeaCrine® is the synthetic version to naturally occurring theacrine (1, 3, 7, 9-tetramethyluric acid) found in the leaves of Camellia kucha tea plants.
What is the natural source of 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 (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].
