Theacrine, also known as 1,3,7,9-tetramethyluric acid, is a purine alkaloid found in Cupuaçu and in a Chinese tea known as Kucha. Normally the high purity 99% are all from chemical synthesis.
L-theanine is the unique free amino acid of green tea, theanine is glutamate – ethyl amide, taste sweet. The 99% purity of L-theanine is fermented from glutamine. Nature L-theanine which extracted from green tea assay around 10%-60%.
Caffeine, we can also find caffeine from green tea and its extracts, the assay is very small. Seems the three ones have a close relationship with tea, then what are the effects of the differences among the three ones?
Caffeine inhibits the actions of our adenosine receptors in the brain, which is the stimulatory activity. L-theanine can help reduce physiological responses to stress by inhibiting excitatory responses in the brain. L-theanine has been shown to allow caffeine to work its brain-boosting charm without letting it raise your blood pressure or induce anxiety. L-theanine knows how to calm caffeine down to help attenuate its adverse effects on your sleep schedule. Which means L-Theanine is antagonistic to caffeine, but both two will works better if combined use. It will reduce the side effect of caffeine.
Both theacrine and caffeine are a kind of alkaloid, so theacrine’s function is similar to caffeine, both of them will increases mental clarity, boosts energy and improves. Theacrine is about as potent as caffeine, Theacrine lasts longer and has a slower building tolerance. Many supplements use theacrine and caffeine as a stimulant while L-theanine to be a dietary supplement.
L-Theanine enhances Theacrine by smoothing out the CNS stimulation it provides and giving you calm, relaxed energy rather than fidgety, nervous energy.
So we can combine L-theanine with theacrine or caffeine to reduce the side effects and will bring you a calmer healthy body.
