Dr. Nenad Naumovski, a leading food science researcher at the University of Canberra, shares groundbreaking insights into L-theanine, an amino acid found in green tea. He discusses its ability to enhance sleep quality, reduce stress, and boost cognitive function by increasing alpha waves in the brain. The conversation also highlights the challenges of developing palatable functional foods that retain health benefits and the potential of L-theanine for various populations, including those with ADHD. Tune in for a deep dive into the science of relaxation!

L-Theanine Is Tea's Relaxing Amino Acid
L-theanine is a non-proteinogenic amino acid most abundant in green tea and linked to relaxation and cognition.
Typical green tea consumption rarely provides therapeutic L-theanine doses without many cups.
insights INSIGHT
Prefer L-Theanine For Physiological Effects
L-theanine (L-form) is the biologically active isomer and modern synthetic sources reach >98% purity.
Early synthesis produced mixed D/L blends, but current products are largely L-theanine.
insights INSIGHT
Rapid Brain Effects Via Alpha Wave Induction
L-theanine crosses the blood-brain barrier and increases alpha brain waves associated with relaxed alertness.
It distributes systemically after absorption and may be taken orally or potentially absorbed in the mouth.

In this episode of fx Medicine by BioCeuticals, host Dr Adrian Lopresti interviews Dr Nenad Naumovski, a leading researcher in food science and human nutrition at the University of Canberra. Dr Naumovski delves into his pioneering research on L-theanine, a non-proteinogenic amino acid found in green tea, highlighting its potential to improve sleep quality, reduce stress, and enhance cognitive function.
Dr. Nenad discusses how L-theanine impacts neurotransmitters and increases alpha waves in the brain to induce relaxation and sleep. He also explains how L-theanine works to improve memory and cognition, which can be understood through its neuroprotective, anti-inflammatory, and antioxidant properties.
The discussion also covers the development of functional food products fortified with nutrients, including L-theanine, and the challenges of making them viable and palatable while maintaining health benefits.
This episode offers invaluable insights into L-theanine's role as a potent therapeutic agent and its positive effects on sleep, cognition and mental health, as well as its place in integrative medicine.
