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.
