​L-Theanine is an amino acid naturally found in tea leaves that has attracted much attention in recent years for its synergistic effects with caffeine. ​Adding L-theanine to coffee not only enhances the flavor of the drink, but also provides multiple health benefits, especially in terms of improving cognitive function and reducing the side effects of caffeine. ​
Synergy between L-theanine and caffeine
Caffeine is popular for its refreshing effects, but some people may experience side effects such as anxiety and palpitations. ​Research shows that L-theanine can relieve the tension and anxiety caused by caffeine by increasing alpha wave activity and promoting relaxation and focus. ​When the two are combined, L-theanine is able to enhance the positive effects of caffeine, such as improving attention and cognitive performance, while reducing its negative effects. ​
Potential benefits for attention deficit hyperactivity disorder (ADHD)
For people with ADHD, the combination of L-theanine and caffeine may have special advantages. ​A study found that this combination helped improve sustained attention and overall cognitive performance in children. ​This suggests that combining L-theanine with coffee may provide a new intervention strategy for people with ADHD.​
Advantages of using L-theanine in coffee products
Adding L-theanine to coffee products can create functional drinks with unique selling points, meeting consumers' demand for healthy and high-performance drinks. ​This innovative combination not only enhances the market competitiveness of the product, but also provides consumers with a more balanced and longer-lasting energy release experience. ​
