Ingredient spotlight


L-Theanine is an amino acid found in the tea plant Camellia sinensis, that has been shown to promote a calm, focused, relaxed wakefulness. By crossing the blood-brain barrier and stimulating alpha brain waves, L-Theanine helps moderate stress levels and create a sense of mental alertness. Studies show that when combined with caffeine, the stimulatory effect of caffeine on the nervous system is counteracted by the moderating effect of L-Theanine.

Thought to be the amino acid equivelant of an adaptogenic herb, we knew L-Theanine would be the perfect match for Productive Energy. This is why we we include ~10x the amount of L-Theanine found in a standard cup of green tea (100mg) in each serving of CogniTea, and pair it with 90mg of natural caffeine for optimal effect.

What People Think of Productive Energy

Hands down the best energy tea out there. I have tried a lot of brands that are either overkill with caffeine and give me jitters, taste artificial, or don't work at all. This combo of theanine and caffeine gives me the perfect amount of energy to focus and flow. The hint of mint is a great subtle flavor too.

I drink it every morning because it works well and I don't crash by midday. I don't notice any difference between the old formula and the new one, I am just happy it is back in stock!

Julia F. | Arlington, VA

I was happily surprised. I was quite tired and slow after a bad night's sleep, a big lunch, and a long meeting. CogniTea perked me right up and cleared out the cobwebs so I could carry on. Good stuff!

Dan B. | Boston, MA

CogniTea was great! I thought it had the perfect amount of peppermint (it wasn't so strong that it was overwhelming, I don't partically like mint flavored things). My brain felt alert but wasn't super wired.

Tiffany M. | Tuscon, AZ

I didn't think tea could replace my morning coffee, but this actually did. I love coffee but it is too acidic for my stomach all the time, so I switch on and off with CogniTea. It is also great when I need an afternoon boost.
