Theanine, 90 Capsules

Dietary SupplementSleepStressGluten FreeL-theanine is a unique amino acid that is found almost exclusively in the tea plant (Camellia sinensis) and which has been used safely in Japan for decades. L-theanine has been shown to positively modify brain waves and the key neurotransmitters involved in mood, focus, and memory. L-theanine enhances the production of the neurotransmitters dopamine and serotonin, and also appears to play a role in the formation of GABA – a neurotransmitter that acts like a "brake" during times of runaway stress. L-theanine also enhances brain alpha-wave activity, a marker of relaxation. This effect has been observed to be most pronounced in individuals subjectively feeling the highest levels of stress.A Japanese study of university students found that 200 mg of L-theanine led to increased brain alpha-waves and a subjective sense of relaxation. In the same study, L-theanine administration also caused a dose-dependent relaxed, yet alert, state of mind without sedation, beginning approximately 40 minutes after ingestion.L-theanine can enhance the production of the neurotransmitters dopamine and serotonin, and it appears to play a role in the formation of GABA – a neurotransmitter that acts like a "brake" during times of runaway stress. L-theanine helps establish balance in the neurotransmitter system, resulting in improvements in the mental/emotional and physical disturbances resulting from being overly stressed.

Our Theanine XR™ Stress Relief formula delivers 400 mg of L-theanine using extended-release technology, so you’ll stay on an even keel all day long.What Is Theanine XR™ Stress Relief?Seeking a “zen” state of mind? Theanine XR™ Stress Relief supports a healthy response to stress so you can stay calm and collected all day long—without sleepiness. This formula’s extended-release technology helps the body manage daytime stress.Maintain a calm energy with our once-a-day Theanine XR™ Stress Relief.Theanine XR™ benefitsPromotes relaxation—without making you sleepyEncourages brain wave patterns associated with wakeful relaxationAll day stress support with extended-release technologyAction-packed days demand a lot from our bodies. Over time, the unmanaged stress can leave us feeling frazzled. For many, drinking a freshly brewed cup of green tea has been the best way to achieve a state of “zen,” even when life is hectic. That’s because green tea is rich in L-theanine, a naturally occurring amino acid that has been shown to support a healthy response to stress.But a green tea break isn’t in the cards for everyone—in fact, when times are chaotic, you’re even less likely to take time for tea time. That’s why we created Theanine XR™ Stress Relief. Our formula delivers 400 mg of green tea’s amino acid L-theanine over a six-hour period to promote a prolonged state of wakeful relaxation, helping the body manage daytime stress.L-theanine and a calm state of mindL-theanine can cross the blood-brain barrier where it’s been shown to help protect brain areas associated with your stress response from oxidative stress. It also helps modulate the activity of excitatory neurotransmitters like glutamate and increase levels of GABA, another neurotransmitter which helps keep the mind calm and relaxed—especially when you’re having “one of those days."Why is this L-theanine formula extended release?Your body metabolizes l-theanine quickly. In fact, you’d need to drink several cups of green tea throughout the day to maintain a steady supply of l-theanine—and green tea by itself contains very low levels of theanine. But extended-release technology allows our Theanine XR™ Stress Relief to stay in your body for up to six hours, giving the body a steady supply of this stress-modulating amino acid.Theanine XR™ Stress Relief is the perfect complement to your fast-paced, modern lifestyle. Each vegetarian tablet is gluten-free and non-GMO. Take one tablet a day and help keep stress at bay.
