L-theanine and Alpha Waves: The science of relaxation with Dr Adrian Lopresti and Dr Nenad Naumovski
FX Medicine Podcast CentralShow Notes
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.

In this podcast episode, Emma Sutherland speaks with Dr Nick Fuller, Clinical Trials Director at the Royal Prince Alfred Hospital Endocrinology Department and researcher at the Charles Perkins Centre. Together they unpack the complex physiology behind weight regain, including metabolic adaptation, appetite-hormone shifts, and the evolutionary mechanisms that make long-term weight loss so challenging.
Dr Stacy Sims, expert in female physiology and training, collaborates with fx Ambassador Lisa Costa-Bir to discuss the intricate relationship between hormones and physical performance.
Jane Hutchens, naturopath and reproductive health and human genetics expert, along with fx Medicine ambassador, Emma Sutherland, raise awareness on the importance of understanding cardiovascular health implications during pregnancy and post-partum. This impacts 1 to 4 percent of women in Australia and is under recognized and underreported.
In part two of our Perspectives podcast, fx Medicine by BioCeuticals ambassadors Lisa Costa-Bir, Dr Michelle Woolhouse, Mick Alexander and Dr Adrian Lopresti, join host Emma Sutherland to explore practical, evidence-aligned treatment strategies for patients with cardiometabolic dysfunction. The discussion covers GLP-1 receptor agonists (GLP-1 RAs) including side effect management and dietary and lifestyle support. They also discuss the evolving landscape of new cardiometabolic medications, and the behavioural, psychological, and social factors that shape long-term cardiometabolic outcomes.
In this insightful conversation, naturopathic doctor and bestselling author Lara Briden joins Emma Sutherland to explore androgen physiology, excess, and sensitivity in women. Together they discuss the complexities of diagnosing androgen excess, including polycystic ovarian syndrome (PCOS) and adrenal-driven cases, and examine the metabolic consequences of chronically elevated androgens. They discuss the challenging clinical presentation of female pattern hair loss or androgenic hair loss talking about cause and realistic treatments.
