Brain Support

  • Raises activity of Alpha brainwaves.*
  • Protects brain cells by blocking glutamate receptors.*
  • Supplies neuroprotective antioxidant activity.*
  • May inhibit excitatory neural states.*

Nootropic Effects

  • Helps instill calm tranquility without sedation.*
  • Promotes memory, concentration, alertness and learning.*
  • Helps attention during difficult, long-duration mental tasks.*

Mind Lab Pro®'s L-Theanine as Suntheanine®

  • Premium Suntheanine®, 100% pure L-isomer form.
  • Patented fermentation process mirrors green tea's profile.
  • Protected by over 40 additional U.S. and international patents.
  • Suntheanine® is shown in human research to raise Alpha brainwaves.
  • Mind Lab Pro®'s 100 mg Suntheanine® dosage supplies the equivalent L-Theanine amount found in 10+ cups of green tea.

Why Mind Lab Pro® Includes L-Theanine

The Alpha brain wave frequency (8-14 Hz) promotes an alert state of relaxation without drowsiness.

Also known as "wakeful relaxation," The Alpha brain wave mind state is considered beneficial for studying, new learning, creative problem solving, art, or other tasks that require quiet contemplation.

Mind Lab Pro® includes L-Theanine as the best evidence-backed nootropic for promoting Alpha brainwaves, supplying unique cognitive support for productivity, creativity and mood.

L-Theanine's brainwave modulation and other brain-supportive bioactivities may support healthy cognitive function in many ways. L-Theanine has been suggested in human research to:

  • Sustain attention over the duration of time-consuming, difficult cognitive tasks.1
  • Exert anti-stress effects by calming excitable nerves, resulting in a slower heart rate and lower stress hormone levels.2
  • Indirectly support cognitive performance by promoting sleep via relaxation, not sedation.3
  • Help reduce the rate of cognitive decline in elderly individuals.4

L-Theanine fits Mind Lab Pro®’s Universal Nootropic strategy with versatile brain benefits for everyone: Younger students under pressure to perform mentally; over-caffeinated professionals who need a cleaner, calmer pick-me-up for productivity; and adults age 50+ who want to maintain their mental sharpness.

How L-Theanine may help with brain health and mental performance

Brain Waves

L-Theanine has been shown to significantly raise Alpha brainwaves. This Alpha activity is suggested to raise mental awareness and arousal, induce relaxation without drowsiness, and significantly influence some aspects of attentional performance.5

Brain Chemicals

L-Theanine can cross the blood-brain barrier to directly support brain chemicals associated with relaxation: GABA, dopamine and serotonin.6 At the same time, L-Theanine binds to glutamate receptors to block the excitatory brain chemical L-Glutamate, which triggers stressful, agitated mind-states and may contribute to brain degeneration concerns.7

Brain Protection

Tea consumption has been associated with benefits for cognitive performance in elderly individuals in cognitive decline.8 This possible advantage has been attributed to tea’s neuroprotective compounds, including polyphenols and L-Theanine.9

Mind Lab Pro® Stack Strategy: L-Theanine + Your Favorite Source of Caffeine for Mental Alertness

Mind Lab Pro® is caffeine-free. One of the reasons why: Many people already drink coffee, tea, energy drinks, and other caffeinated beverages to boost their alertness during the day. Mind Lab Pro®'s L-Theanine works as a complement to caffeine:

L-Theanine is suggested to potentiate the effects of caffeine, and has been shown to attenuate the blood vessel constriction and reduction in cerebral circulation that accompanies caffeine consumption.10

L-Theanine + Caffeine is a popular nootropic stack, suggested to provide a clean vitality lift with fewer jitters than caffeine alone. 

Mind Lab Pro® supplies L-Theanine in a caffeine-free formula, enabling more precise control over stimulant intake and the L-Theanine + Caffeine stack's ultimate nootropic effects.
