In recent years, l-theanine has emerged as a trendy ingredient in various beverages, particularly lattes. This amino acid offers a unique flavor profile and potential benefits, making it a popular choice among health-conscious consumers. With its calming yet alerting effects, it’s no wonder that cafes and restaurants are adding l-theanine-infused drinks to their menus.
What is l-theanine?
L-theanine is a non-protein amino acid found naturally in green, black, and oolong teas, according to Yoshua Quinones, MD, an internal medicine doctor with Medical Offices of Manhattan and a contributor to LabFinder. This amino acid acts as an antioxidant, helping to reduce inflammation in the body. “It’s well-known for its ability to induce a state of calm while maintaining alertness,” Dr. Quinones explains.
If you regularly enjoy matcha, you’re likely familiar with this effect. The caffeine in green tea promotes alertness, while l-theanine counters the jitteriness often associated with coffee. Sunjya Schweig, MD, a functional medicine doctor at the California Center for Functional Medicine, emphasizes that adding l-theanine to coffee allows consumers to enjoy similar benefits without switching to matcha.
“L-theanine has grown increasingly popular as a means for individuals to feel calmer and more focused without sedation,” states Jennifer Timmons, MD, functional medicine doctor and medical director of Timmons Wellness. L-theanine influences multiple neurotransmitter systems in the brain, including GABA, dopamine, and serotonin systems. It promotes alpha brainwave activity associated with a relaxed yet alert mental state. As Dr. Timmons explains, “Instead of feeling drowsy and sedated, you’re alert and relaxed. It also lowers cortisol levels, contributing to a greater sense of calm.”
This calming effect has led to an increase in l-theanine being incorporated into nonalcoholic drinks. If you struggle with sleep due to stress or racing thoughts, a l-theanine supplement may provide relief through its cortisol-lowering properties.
Jeffrey Bland, PhD, a biochemist and longevity expert at Big Bold Health, notes that certain clinical studies suggest l-theanine can help individuals fall asleep faster when taken 30 to 60 minutes before bedtime, despite not being classified as a sedative. Additionally, a 2022 study published in Frontiers in Nutrition showed that supplementing l-theanine may enhance sleep quality by reducing brain overstimulation that can disrupt rest.
So why is l-theanine trending now? According to Brian Anderson, DO, founder of the Anderson Longevity Clinic, the growing interest in brain health plays a significant role. “Optimized brain health is currently a significant trend in longevity-oriented health care. L-theanine aligns with this trend and is widely accessible,” he states.
Dr. Schweig adds that the quest for improved sleep contributes to the ingredient’s rising popularity. “People are experiencing heightened stress and sleep disturbances. When they inquire about solutions, l-theanine is often recommended by AI tools,” he explains.
