Marsha, I'm so happy you are enjoying my favorite organic Japanese Sencha!
One of the things I love most about this Sencha is how fresh and sweet it is. Superior Japanese Sencha (First Flush) also has 25–30 mg of L-Theanine per cup.
L-theanine is the amino acid responsible for the calm, focused alertness that distinguishes tea from every other caffeinated beverage. It promotes alpha brain wave activity, the same frequency your brain reaches during relaxed concentration — and it works synergistically with caffeine to deliver clarity without the jitter or crash. All true teas (Camellia sinensis) contain L-theanine.
