L-Theanine is a naturally occurring amino acid best known for promoting a calm yet alert mental state—making it ideal for reducing stress and improving focus without causing drowsiness. Sourced primarily from green tea leaves, this gentle supplement supports mental clarity, emotional balance, and restful sleep, all without the side effects often linked to sedatives or stimulants. Whether you’re navigating daily pressures, dealing with occasional anxiety, or looking to sharpen concentration, L-Theanine provides a natural, non-addictive solution. By positively influencing neurotransmitters like GABA, serotonin, and dopamine, and encouraging alpha brain wave activity, it helps regulate mood and calm mental noise. Perfect for students, professionals, and anyone seeking balanced energy, this supplement also complements broader cognitive and emotional support options available in our full Brain Supplements range.
This supplement works primarily by influencing neurotransmitters in the brain, including increasing GABA, serotonin, and dopamine levels, which help regulate mood and sleep. It also promotes alpha brain wave activity, associated with a relaxed yet alert mental state. For those seeking a more direct sleep aid, L-Theanine can be combined with other ingredients in products found in our Sleeping Tablets collection.
