What do we know about using specific probiotics for different health conditions? And is it time to move away from broad-spectrum probiotics and into condition-specific strains? With an explosion of new research on probiotics and a recent change in nomenclature, it’s easy to get confused. In this episode of New Frontiers, I lean on Dr. Noelle Patno’s extensive research knowledge to tease apart the science on probiotics. Dr. Patno holds a PhD in Molecular Metabolism and Nutrition and has designed and monitored clinical trials on microbiome and immune health. Together, we dive into the latest evidence on therapeutic uses of specific probiotic strains, including Lactobacillus rhamnosus GR-1, for women’s health and other conditions. Dr. Patno also shares excellent pearls on dosing, duration, delivery methods and antibiotic resistance. Many thanks to Noelle and the team at Metagenics for always leading the way and researching interventions. Appreciate you listening, sharing, and commenting, and always, thanks for subscribing.  - DrKF

Sergey Young's Tech Innovations for Longevity and Biological Age Reversal

The therapeutic value of curcumin makes it a fabulous recommendation as both a foundational and medicinal supplement. And since finding a preparation that is bioavailable is key to efficacy, affordability, and patient compliance, I’m excited to have Dr. Sonia Malani (from Integrative Therapeutics) here to talk about the latest advances in curcumin deliverability. 
Dr. Malani breaks down the progress of curcumin deliverability and the keys to bioavailability in a way that is simple to understand and easy to pass on to our patients in order to help them move away from the less effective brands that are currently lining the shelves of local markets so they get the therapeutic influence we are hoping for. Lots to learn, let me know what think in this great interview sponsored by Integrative Therapeutics! ~DrKF

Advances in Curcumin Bioavailability for Improved Absorption in Patients

Imagine accurately determining the status of your skin’s age to tell whether it is younger or older than your chronological age, and then use this technology to determine whether expensive anti-aging serums and creams are effective, or actually causing more harm than good. Amazing, right?

This is precisely the technology Dr. Carolina Reis Oliveira and her fellow stem cell biologists at OneSkin created and you will find this interview fascinating on so many levels – I know I sure did! After creating their skin clock, the OneSkin team discovered peptide OS1, which targets senescent cells, one of the root mechanisms of aging, and is being shown in current studies to have a positive effect on hydration, firmness, elasticity, and the skin barrier.  

Listen as Dr. Reis explains the science and ongoing studies exploring the possible benefits of OS1 for the skin microbiome, hair loss, inflammation, and overall health.

Disrupting Anti-Aging Skincare by Targeting Senescent Cells

As we gain insight into microbiome impact on our health, we need accurate tests that tell us not only what and how much is there, but also which metabolites, or post-biotics created that can have downstream effects. So today I’m thrilled to welcome the brilliant Dr. Erika Ebbel Angle, PhD, biochemist, CEO, and co-founder of Ixcela, to discuss their fingerstick gut microbiome test. We’ll discuss the 11 key markers, the value of a blood sample over urine, and the impact of endurance sports and chronic stress on health markers as revealed by the test.

We also chat about my own results, how impressed I was by the insight provided – and how they clearly identified changes I could make to improve my markers. Listen and take notes -- I know I did! ~DrKF

Measuring Metabolites of Dysbiosis and Gut Function to Create Targeted Interventions

Can functional medicine unlock the secrets to healthy aging? In this special preview of the Functional Medicine is Longevity Medicine™ Masterclass happening on September 17- September 19, 2025, Dr. Kara Fitzgerald sits down with three leading voices in medicine and research:

- Dr. Bob Rountree: functional medicine pioneer in integrative approaches to health

- Dr. Dale Bredesen: internationally recognized expert on Alzheimer’s prevention and reversal

- Dr. Charles Serhan: Harvard researcher on inflammation resolution and aging biology

Together, they explore how functional medicine reframes longevity by addressing root causes, supporting cognitive health, and resolving chronic inflammation.

Whether you’re a clinician, health professional, or simply passionate about living longer and healthier, this conversation offers a glimpse into the science and practical applications that are transforming longevity medicine.

Why Functional Medicine Is the Future of Longevity

As a former Olympian and current Iron Man triathlete, (he qualified for the world championship in Hawaii this year!) Dr. Keith McCormick was diagnosed with severe osteoporosis at 45 years old. His own healing journey lead him to become a world expert on treating osteoporosis from a functional and integrative perspective. His 2008 book, The Whole Body Approach to Treating Osteoporosis, is useful for patient and clinician alike. This podcast is a goldmine of pearls for clinicians treating individuals with bone loss. Topics covered include underlying pathogenic mechanisms, laboratory evaluations and treatments-pharmaceutical and natural. Health savvy patients will find Dr. McCormick’s content useful.

According to Dr. Bob Hedaya, it’s malpractice NOT to use functional medicine when practicing psychiatry. ALL of the nodes on the Functional Medicine Matrix [gastrointestinal, endocrine, immune, toxicity, nutritional status and especially psychological, social and spiritual] influence mental health, mental function and brain function. The bottom line is, a good functional approach yields better health, less medicine.  In this case-focused inspiring podcast, hear about Dr. Hedaya’s years of clinical experience in using functional medicine to address tough psychiatric conditions.
