Additional Information

People take L-Theanine to support a calm, relaxed mood and healthy response to stress.**

L-Theanine is an amino acid that can be absorbed across the brain, where it has been linked to an increase in alpha- waves in the brain. The increase of alpha- waves helps you to feel more relaxed without the drowsy side effects common in most anxiety prescription medication. As a natural phytochemical found in Japanese green tea, L-Theanine supports a calm and relaxed mood without the drowsiness or negative side effects associated with other prescription calming agents.**

    Q: Does L-Theanine help with anxiety?
    A: In a clinical study, participants showed decreased levels of stress with improved cognitive function after supplementing with L-Theanine for four weeks! It even showed an improvement of sleep quality. With the recent restrictions on prescribing benzodiazepines to help patients manage generalized anxiety, L-Theanine has been a popular alternative among Psychiatrists and Primary Care Physicians alike. L-Theanine enhances GABA production in the body, with more GABA there is more dopamine and serotonin that promote the feelings of calm well-being.

    Q: How long does L-Theanine take to kick in?
    A: Using L-Theanine for sleep, it becomes effective within 30 - 40 minutes after taking it and calming effects may last 8 - 10 hours. Vitamin World’s rapid release capsules are designed to ensure you get relief as soon as possible, especially if you are experiencing uncomfortable anxiety symptoms.

    Q: Can L-Theanine help you lose weight?
    A: L-Theanine helps improve sleep quality, getting better sleep and reducing stress are key factors in supporting and maintaining a healthy weight.
