What makes L-Theanine and caffeine so great together?
Caffeine is great for concentration, improving attention, and focus. The downside is increased heart rate, blood pressure, and anxious / jittery feelings.
L Theanine is a relaxant that can reduce heart rate and blood pressure , promote alpha brain waves (associated with relaxation) and provide balance for the brain to avoid jitters.
But combined, caffeine and L-theanine work better together.
You can concentrate on your work more thoroughly, be more creative, and achieve more success with the absence of headaches, crashes, and anxiety. The combination gives you the power to perform better than taking either alone.
Don’t believe me? Here is some evidence:
- “…suggests that L-theanine and caffeine in combination are beneficial for improving performance on cognitively demanding tasks.” (Journal of Nutritional Neuroscience, 2008)
- “…’Headache’ and ‘tired’ ratings were reduced and ‘alert’ ratings increased. There was also a significant positive caffeine x L-theanine interaction on delayed word recognition reaction time.” (Journal of Biological Psychology, 2008)
According to the Reddit Nootropics group “The combination of L-theanine and caffeine may improve attention more than caffeine alone.”
Most companies find individual ingredients with studies, but have no evidence for the combinations that they make.
