The benefits of L-theanine

Studies have found that Theanine has several health benefits, such as reducing stress and anxiety, improving cognitive function, and boosting immunity. L-theanine has been shown to increase alpha waves, a pattern of brain activity associated with a more relaxed state. These alpha waves occur in the brain just moments after taking L-theanine. L-theanine tends to increase alpha waves may explain its stress and anxiety-reducing effects. This effect also helps reduce stress-related symptoms such as headache, indigestion, and some studies have found that L-theanine can lower high blood pressure, but it’s dependent on high doses of Theanine.

How to use L-theanine for a Sense of Calmness

Theanine can be consumed in supplement form or as a tea. For optimal results, taking theanine supplements with food is recommended to prevent gastrointestinal upset. To brew a theanine tea, steep 1-2 grams of tea leaves in water for 5 minutes. Theanine can be taken with other supplements, such as magnesium, to increase its calming effect.

The recommended dosage is 100-200mg per day. Speak with your doctor before taking Theanine to rule out any possible contraindications or determine an optimal dosage for you.

Final word

Tea leaves or theanine supplements can be a helpful addition to your routine if you’re feeling stressed, anxious, or need a sense of calmness. This is achieved by reducing the production of stress hormones and producing alpha waves in the brain. When taken before bedtime, Theanine can also help improve sleep quality.
