One of the primary benefits of combining L-theanine with caffeine is the **improvement in cognitive function**. Studies have shown that this combination can help **improve focus, attention, and memory**. Additionally, the L-theanine helps to **counterbalance some of the negative effects** of caffeine, such as jitters and **anxiety**. Another benefit of taking L-theanine with coffee is that it **can help regulate sleep**. Caffeine can disrupt sleep patterns, making it difficult to fall asleep or stay asleep. However, L-theanine can help **regulate the release of caffeine in the body**, allowing for a more gradual release throughout the day and **reducing the chances of caffeine-related sleep disturbances**. L-theanine also has a number of mental health benefits. This amino acid has been shown to **reduce stress, anxiety, and depression**, making it a valuable addition to the diet of anyone looking to improve their overall well-being. ## How I do it For 350ml of coffee (about 1 mug), I take about 150-200mg of L-Theanine 30 minutes before drinking. *Disclaimer: None of the above should be considered medical advice.
