Why Pair L-Theanine With Caffeine?

Our Organic Caffeine comes from Green Tea and is one of the purest available. Our L-Theanine (a naturally occurring amino acid also found in Green Tea) is produced through an enzyme assisted process that uses Green Tea leaves as one of several starting materials, which allows us to increase its purity and benefits to the user.

Multiple studies support that using Caffeine and L-Theanine together can reduce jitters and heighten concentration and cognitive alertness, while also boosting your mood.*

It’s this combination of Caffeine and L-Theanine that makes Green Tea Leaves one of the world's most powerful cognitive boosters when used at the correct dosage.*
