nootropics review Green tea (and indirectly l-theanine) continues to be used a standard health-tonic throughout Asia for untold centuries; renowned due to its plethora of medicinal properties – green tea leaf stands intransigently against big-pharma and this also defiance and prolific superiority may be its sure approach to wide-spread popularity and success.
Mechanism
Although green tea leaf is abundant in antioxidants and potentiators of glut4 activity (Glucose transporter type 4) this information will explore the amino acid l-theanine as well as its effects in-vivo. Theanine is glutamine and glutamate analog, and readily crosses the blood-brain barrier making it a psychoactive chemical. Able to decrease both mental and physical stress, theanine demonstrates an affinity to the brain inhibitory transmitter GABA. Its mechanisms of action don’t stop there. Akin to the racetam family – theanine has additionally demonstrated moderate affinity with AMPA receptors and may be shown to boost the monoamine best nootropic stack neurotransmitter dopamine. In studies theanine has demonstrated efficacy to advertise alpha-wave brain patterns – linked to meditation, increased concentration and creativity. People debilitated with panic attacks take note: l-theanine is clinically demonstrated to acquire significant anxiolytic properties.
Uses
Anxiolytic mechanism will benefit those with anxiety attacks

Boosts the action of gamma delta T cells hence increasing immuno-response.
Potent anti-psychotic to use in schizophrenia
Issues
The consumption of green tea extract in Asian countries might only lead to a typical daily exposure of 20mg of l-theanine or less thereby long-term safety in humans hasn’t been established. Rats fed high dose l-theanine for 13 weeks demonstrated no biological abnormalities perhaps indicating that l-theanine is often a safe and well tolerated amino acid.
Dosage
As always precautionary allergy exams are recommended employing a minute dose; one aspects established the existing recommended dosage is between 50-200mg and electronic scales is going to be required to accurately ascertain this quantity. As always I recommend the full blood ensure that you consultation using a health practitioner before commencing any nootropic regime.
Experiences
