While tea contains a number of active constituents, L-Theanine comprises about 1-2% of its dry weight, contributes significantly to its characteristic taste, and is the most well researched for health benefits.(2)\u003c\/p\u003e\n\u003ch3\u003e\u003cem\u003eHelps Relieve Nervous System Stress and Mild Anxiety\u003c\/em\u003e\u003c\/h3\u003e\n\u003cp\u003eL-Theanine crosses the blood brain barrier (BBB) and increases the secretion and function of neurotransmitters, especially serotonin, dopamine and gamma aminobutyric acid (GABA).(2,3,4) As neurotransmitters typically modulate emotional and physiological states in humans, L-Theanine is believed to also influence these states.(3)\u003c\/p\u003e\n\u003cp\u003eL-Theanine’s competitive role against neuroexcitation and well known relaxing effects are attributed to its ability to block the binding of L-glutamic acid to glutamate receptors in the brain. Increased glutamate levels are commonly induced by acute stressors and contribute to the stimulation of the sympathetic nervous system. Measurable indices of acute stress responses include several autonomic parameters, including heart rate (HR), blood pressure (BP), and immunoglobulin A (IgA).(3) Furthermore, L-Theanine may support neuroinhibition via glycine receptors.(5)\u003c\/p\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cstrong\u003eResearch Study:\u003c\/strong\u003e The influence of L-Theanine on stress-induced psychological and physiological states were investigated in a randomized, controlled study in 2007. Twelve healthy male undergraduate students underwent four separate trials: in the first trial L-Theanine (200mg) was administered at the start (L-Theanine 1) and in the second trial L-Theanine (200mg) was taken midway (L-Theanine 2), while the third and fourth trial involved taking a placebo or no treatment at all. Study participants were exposed to an acute stressor (a mental arithmetic task) over a period of 20 minutes. Psychological measures included self-evaluated (subjective) perception of stress as well as physiological measures such as HR and concentrations of IgA. L-Theanine intake was shown to significantly lower subjective stress scores in L-Theanine 1 and 2 conditions, and reduce both HR and salivary IgA responses to the acute stress task when compared to placebo. Oral intake of L-Theanine was consequently suggested to reduce acute stress responses by buffering sympathetic activity (Figure 1).(3)\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003cp\u003eThere are four basic brain wave patterns (alpha, beta, delta, and theta), each of which are associated with different mental states and states of consciousness. Alpha-brain waves typically indicate a relaxed but alert state.(6)\u003c\/p\u003e\n\u003cp\u003eL-Theanine induces detectable alpha-brain wave activity after 30 minutes in a dose dependant manner, and leads to a relaxed, yet alert, state of mind without causing drowsiness or sedation.(2,6,8) Perception of relaxation coincides with the detection of alpha brain waves. However, this effect may only be achieved at doses above those found in a cup of tea (typically around 20mg).(8) Research has demonstrated that consumption of about 200mg of L-Theanine results in an increase in alpha wave activity in the brain within 30-40 minutes.(6,9) L-Theanine has also been shown to support, indirectly, the ability to counteract the stimulatory effects of cortisol and caffeine.(2)\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" alt=\"Vera’s Formulations Ultra Theanine Figure 1 - Effects of L-Theanine on Heart Rate HealthMasters\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2075\/8503\/files\/Vera_s_Formulations_Ultra_Theanine_Figure_1_-_Effects_of_L-Theanine_on_Heart_Rate_HealthMasters_600x600.jpg?v=1586305959\"\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eFigure 1: Effects of L-Theanine on Heart Rate (3)\u003c\/h3\u003e\n\u003ch3\u003e\u003cem\u003eNeuroprotection and Support of Cognitive Function\u003c\/em\u003e\u003c\/h3\u003e\n\u003cp\u003eL-Theanine has been shown to possess neuroprotective and cognitive enhancing activity.(4,10-12) Its neuroprotective effect is suggested to be related to its antagonistic effects on glutamate receptors as well as glutamate transporters,(4,12) while important aspects of attention are supported by alpha wave activity.(8,3)\u003c\/p\u003e\n\u003cp\u003eAs supported by various randomized, controlled studies, L-Theanine may also negate the stimulatory effect of caffeine on blood pressure. (2,12) In combination with caffeine, L-Theanine has been shown to improve and help focus attention during demanding cognitive tasks, (14,15) increase reaction time, (16) improve speed and accuracy of performance of attention switching tasks, and reduce susceptibility to distracting information.(17)\u003c\/p\u003e\n\u003ch3\u003e\u003cem\u003ePossesses Antioxidant Activity and May Support Immunity\u003c\/em\u003e\u003c\/h3\u003e\n\u003cp\u003eThe antioxidant activity of L-Theanine has been studied in relation to LDL cholesterol, liver and neurologic function.

found almost exclusively in tea (Camellia sinensis). While tea contains a number of active constituents, L-Theanine comprises about 1-2% of its dry weight, contributes significantly to its characteristic taste, and is the most well researched for health benefits.(2)\u003c\/p\u003e\n\u003ch3\u003e\u003cem\u003eHelps Relieve Nervous System Stress and Mild Anxiety\u003c\/em\u003e\u003c\/h3\u003e\n\u003cp\u003eL-Theanine crosses the blood brain barrier (BBB) and increases the secretion and function of neurotransmitters, especially serotonin, dopamine and gamma aminobutyric acid (GABA).(2,3,4) As neurotransmitters typically modulate emotional and physiological states in humans, L-Theanine is believed to also influence these states.(3)\u003c\/p\u003e\n\u003cp\u003eL-Theanine’s competitive role against neuroexcitation and well known relaxing effects are attributed to its ability to block the binding of L-glutamic acid to glutamate receptors in the brain. Increased glutamate levels are commonly induced by acute stressors and contribute to the stimulation of the sympathetic nervous system. Measurable indices of acute stress responses include several autonomic parameters, including heart rate (HR), blood pressure (BP), and immunoglobulin A (IgA).(3) Furthermore, L-Theanine may support neuroinhibition via glycine receptors.(5)\u003c\/p\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cstrong\u003eResearch Study:\u003c\/strong\u003e The influence of L-Theanine on stress-induced psychological and physiological states were investigated in a randomized, controlled study in 2007. Twelve healthy male undergraduate students underwent four separate trials: in the first trial L-Theanine (200mg) was administered at the start (L-Theanine 1) and in the second trial L-Theanine (200mg) was taken midway (L-Theanine 2), while the third and fourth trial involved taking a placebo or no treatment at all. Study participants were exposed to an acute stressor (a mental arithmetic task) over a period of 20 minutes. Psychological measures included self-evaluated (subjective) perception of stress as well as physiological measures such as HR and concentrations of IgA. L-Theanine intake was shown to significantly lower subjective stress scores in L-Theanine 1 and 2 conditions, and reduce both HR and salivary IgA responses to the acute stress task when compared to placebo. Oral intake of L-Theanine was consequently suggested to reduce acute stress responses by buffering sympathetic activity (Figure 1).(3)\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003cp\u003eThere are four basic brain wave patterns (alpha, beta, delta, and theta), each of which are associated with different mental states and states of consciousness. Alpha-brain waves typically indicate a relaxed but alert state.(6)\u003c\/p\u003e\n\u003cp\u003eL-Theanine induces detectable alpha-brain wave activity after 30 minutes in a dose dependant manner, and leads to a relaxed, yet alert, state of mind without causing drowsiness or sedation.(2,6,8) Perception of relaxation coincides with the detection of alpha brain waves. However, this effect may only be achieved at doses above those found in a cup of tea (typically around 20mg).(8) Research has demonstrated that consumption of about 200mg of L-Theanine results in an increase in alpha wave activity in the brain within 30-40 minutes.(6,9) L-Theanine has also been shown to support, indirectly, the ability to counteract the stimulatory effects of cortisol and caffeine.(2)\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" alt=\"Vera’s Formulations Ultra Theanine Figure 1 - Effects of L-Theanine on Heart Rate HealthMasters\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2075\/8503\/files\/Vera_s_Formulations_Ultra_Theanine_Figure_1_-_Effects_of_L-Theanine_on_Heart_Rate_HealthMasters_600x600.jpg?v=1586305959\"\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eFigure 1: Effects of L-Theanine on Heart Rate (3)\u003c\/h3\u003e\n\u003ch3\u003e\u003cem\u003eNeuroprotection and Support of Cognitive Function\u003c\/em\u003e\u003c\/h3\u003e\n\u003cp\u003eL-Theanine has been shown to possess neuroprotective and cognitive enhancing activity.(4,10-12) Its neuroprotective effect is suggested to be related to its antagonistic effects on glutamate receptors as well as glutamate transporters,(4,12) while important aspects of attention are supported by alpha wave activity.(8,3)\u003c\/p\u003e\n\u003cp\u003eAs supported by various randomized, controlled studies, L-Theanine may also negate the stimulatory effect of caffeine on blood pressure. (2,12) In combination with caffeine, L-Theanine has been shown to improve and help focus attention during demanding cognitive tasks, (14,15) increase reaction time, (16) improve speed and accuracy of performance of attention switching tasks, and reduce susceptibility to distracting information.(17)\u003c\/p\u003e\n\u003ch3\u003e\u003cem\u003ePossesses Antioxidant Activity and May Support Immunity\u003c\/em\u003e\u003c\/h3\u003e\n\u003cp\u003eThe antioxidant activity of L-Theanine has been studied in relation to LDL cholesterol, liver and neurologic function.
