Caffeine & L-Theanine

A great marriage is sometimes the combination of opposites that attract. So it is with the union of caffeine and L-theanine. To put it simply:

Caffeine stimulates the brain and sharpens mental acuity, but the effects often come with an increase in heart rate and blood pressure that results in nervousness or classic caffeine jitters.

L-Theanine inhibits stimulation in the brain which can lower heart rate, blood pressure and stress hormone levels in the body, producing a sense of calm.

Blissfully wed, caffeine and L-theanine bring out the best in each other out and become an amazing amalgamation that can elevate mood while enhancing focus and mental clarity.

Loud Brew has been scientifically formulated to bring you the happy benefits of a well-balanced blend of caffeine and L-Theanine in a flavorful, well-crafted coffee.

Sounds too good to be true, but…

We're not making this up!
