Health benefits at a glance:

First of all, what is L-theanine? It’s a naturally occurring amino acid that has been shown to support a healthy response to stress. (1)

Action-packed days demand a lot from our bodies. Over time, unmanaged stress can leave us feeling frazzled. (2) And most people are familiar with the notion “it’s just one of those days”.

Green tea is rich in L-theanine, and for many, drinking a freshly brewed cup of green tea can help soothe the mind when life is hectic. A green tea break isn’t always an option though, and that’s why Life Extension created Theanine XR™ Stress Relief.

Theanine XR™ Stress Relief can provide all-day stress support with extended-release technology, so you can stay calm and collected all day long — without drowsines.

Why it works:

Theanine XR™ Stress Relief formula provides 400 mg of green tea’s amino acid L-theanine over a six-hour period. This is to promote a prolonged state of wakeful relaxation and in that way helping the body manage daytime stress. (1,3)

L-theanine is shown to significantly increase brain wave activity that can help promote a state of wakeful rest. (4) It can also help decrease glutamate signaling, effectively calming the mind — even during those days where you feel you have too much on your plate. (1,3,6)

The science behind the product:

L-theanine and a relaxed mind

Studies indicate that L-theanine can cross the brain-blood barrier, positively affecting the brain’s pathways associated with mental relaxation and calmness. It has been shown to help protect brain areas associated with your stress response from oxidative stress. (4)

It can also help modulate the activity of excitatory neurotransmitters like glutamate and increase levels of GABA (5), another neurotransmitter that helps keep the mind calm and relaxed, especially when you’re having “one of those days.” (1,3,6)

Formula with extended-release of l-theanine

Your body metabolizes L-theanine quickly. You would need to drink several cups of green tea during the day or take multiple doses of regular L-theanine to maintain a steady supply of L-theanine, and green tea by itself contains very low levels of theanine.

Using an immediate- and extended-release technology, scientists have found a way to allow L-theanine to stay in the body for up to six hours.

One study in moderately stressed adults found that a single dose of this form of L-theanine led to a greater increase in indicators of relaxation compared to placebo. (7)

This unique technology allow Theanine XR™ Stress Relief to provide a steady supply of the stress-modulating amino acid.  Each vegetarian tablet is gluten-free and non-GMO.

This supplement can be the perfect complement to your busy, modern lifestyle.
