L-TeaActive™ (L-Theanine) is an amino acid derived from green tea through a proprietary manufacturing process. L-theanine safely induces relaxation (without drowsiness) and reduces stress. Extreme stress can be detrimental to our health by impairing normal hormonal balance, the immune system and our sense of well-being. L-TeaActive™ works by increasing production of Alpha waves in the brain responsible for a relaxed state of mind and mental alertness. Blue California is proud to offer this natural high-purity L-Theanine, confirmed as GRAS by the FDA in 2010, at a very competitive price. We want your product to be efficacious and affordable!
