Caffeine + L-theanine is a two-component dietary supplement that combines a strong dose of caffeine with the non-essential amino acid L-theanine. You will appreciate caffeine, especially thanks to its connection with increased alertness and improved concentration. L-theanine from green tea functionally complements the whole mixture. It is thus an ideal choice for students, managers, and athletes.

As a gym rat who wants to be 100% a gym rat and 100% a university student, this is a very helpful product. Combining these two things is a game changer for me. Love it.

I usually respond very well to caffeine and I only need 100–200 mg to have a good workout, but with this version I didn’t feel anything else. I tried 1 tablet—nothing. I tried 2 tablets—nothing. I tried 4 tablets—an average effect. Compared to plain caffeine, where just one tablet makes the effect very intense, this one has almost no effect. Disappointing…Was this review helpful to you?Filip
