Product Details

Action-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 mind

L-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.
