Dr. Sandison confesses that when she first heard Dr. Dale Bredesen talk about his work reversing cognitive decline and Alzheimer's disease she was skeptical. But when she started to apply the Bredesen principles in her clinical work and saw just how meaningful the improvements were to patients' symptoms and quality of life, as she puts it: "...how do I do anything else with my life, but basically tell as many people who will listen that this is possible?" She then went on to found the first two residential care facilities for individuals with cognitive decline that are based on the Bredesen approach. She's published research on her clinical outcomes and is continuing to gather more data for publication. The information and inspiration she shares are relevant to anyone dealing with cognitive decline, caring for someone with cognitive decline, or even those of us who want to preserve and optimize cognitive function as we move through life. I found her report that environmental toxins were one of the most common findings among her patient population illuminating. - DrKF Head to https://www.drkarafitzgerald.com/fxme... for the transcription and all the resources.

Get ready for a deep dive into the world of cellular senescence and its implications for aging. Dr. Greg Kelly joins me on New Frontiers to explain the science behind targeting this Hallmark of Aging and share natural compounds and activities that target cellular senescence. I am particularly excited for you to hear his thoughts around dosing and cyclical timing of exposure to senolytic compounds, such as fisetin, luteolin, quercetin, and piperlongumine, and why that may make the difference between having the effect you want... or not. Don't miss his advice on smart exercise tweaks for aging and the caution that overdoing it with exercise in our later years is much more harmful than it was in our twenties. Lots to unpack here.

I'm excited to welcome Dr. Barry Sears, the renowned creator of the Zone Diet and a pillar in our field. Dr. Sears has not only authored bestsellers but has also made incredibly important contributions to clinical practice which we still rely on today: He is, for instance, the scientist who put the use of the AA:EPA ratio on the map. Dr. Sears provides elegant and accessible explanations of the unassailable importance of diet in addressing inflammation, metabolic health, chronic disease, and longevity, and the role that fatty acids play in that milieu. And while he and I might not agree that polyphenols need to be absorbed intact for benefit - there's plenty of evidence that their postbiotic products are very important players, especially in their interactions with the epigenome - his concerns about the chemical structure of highly concentrated fish oil supplements (with the potential for isomerization, as he argues) has opened my eyes and is important, without doubt. I think the jury is still out as to whether there is a negative influence of isomerization in highly concentrated EPA and DHA, but it's worthy of further investigation and (importantly) is another factor in the argument for a whole-food approach. - DrKF Check out the show notes at https://www.drkarafitzgerald.com/fxmed-podcast/ for all the relevant links and resources.

Fellow clinicians, get ready for a mind-blowing conversation with Dr. Nathan Price, Chief Scientific Officer of Thorne HealthTech and author of The Age of Scientific Wellness. Imagine harnessing AI to predict outcomes of our functional interventions (diet, supplements, lifestyle) by implementing a “digital twin” model that is populated with all of your patient’s bio data. And being able to test the response of our treatments (and importantly, the synergistic response of multimodal interventions). It’s heady stuff, but amazingly, it is where we are headed today. Dr. Price illustrates the incredible potential this technology brings for personalized evidence-based medicine, such as tailoring interventions based on microbial markers or targeting specific lifestyle changes for Alzheimer's prevention. The podcast is a captivating exploration of cutting-edge concepts and provides a glimpse into the exciting future of healthcare. I was wowed by my conversation with Nathan and can’t wait to start kicking the tires on this baby. I know you’ll feel the same. ~DrKF Check out the show notes at www.drkarafitzgerald.com/fxmed-podcast/ for all the relevant links and resources.

It was a career-defining (and perhaps life changing) moment when Dr. Vittorio Sebastiano, a reproductive biologist by training, realized that because we are able to create life, that same body of information could be harnessed to create youth - that is, radically reverse our biological aging process to a younger time point without losing cellular identity. In 2014, he and his lab began unpacking this epiphany. They made the radical decision to conduct their investigations in human cells and tissue rather than in rodents, with the expectation that such a start would be a better bridge to human clinical trials. Flash forward a decade and Dr. Sebastiano and his team stand poised to begin trials in humans. Dr. Sebastiano is, in my opinion, one of the most extraordinary scientists in the longevity space today who flies under the radar of most of us in functional medicine. In this podcast - which is actually two-in-one because I continued the conversation with him on a second date - you’ll hear about the remarkable work they’re undertaking at his lab. For example: They’ve created a biological clock that encompasses the whole genome consisting of millions and millions of CpG sites. They are able to clearly demonstrate the reversal of bioage using their methodology - a cocktail of Yamanaka factors plus, with clear time limits - which changes the epigenome first, and in so doing influences all of the hallmarks of aging. Teaser: they’ve identified one intervention routinely used in clinical practice that influences their bio age clock in the same way that their cocktail does. What is it? I was riveted with this conversation, as I am sure you’ll be. Leave a review if you like it, and - Yes - let me know what you think. I know this will prompt deep questions for you, as it did for me. ~DrKF Check out the show notes at www.drkarafitzgerald.com/fxmed-podcast/ for all the relevant links and resources.

Aging itself stands as the paramount driver of disease. As functional practitioners, the question arises: How can we assess biological age to make precise corrections that foster both healthspan and lifespan? Enter the era of omics, where metabolomics emerges as an exceptional tool with transformative potential. I'm thrilled to welcome back Dr. Betsy Redmond, longtime friend and the senior education specialist at Diagnostic Solutions Laboratory, to New Frontiers to lead us on this discussion.Together, we'll take a deep dive into specific metabolites and pathways intricately linked to aging, mood, inflammation, and gut health and you’ll hear about equol, a rising star on the postbiotic scene. We'll even unravel some surprising insights from my own test results! Be sure to grab a copy of the Sample Report and pull up a seat for this fascinating discussion packed with valuable takeaways for yourself and your practice. ~DrKF You'll find it all at www.drkarafitzgerald.com/fxmed-podcast/

Working in healthcare brings a unique set of challenges and stressors. But the truth is that any of us can get to burnout through challenging circumstances of work or study. And the consequences can range from severe to devastating. Burnout still hasn't been fully understood or recognized by the medical profession and other industries - there is still no official diagnosis classification. Along with other mental health disorders, it is often still (wrongly) stigmatized and can even sometimes be seen as a "badge of honor," much to our detriment. Dr. Jonathan Prousky, Chief Naturopathic Medical Officer at the Canadian College of Naturopathic Medicine, joins me once again in this New Frontiers episode to explore the state of burnout in healthcare workers and beyond. Whether you work in our field or not, I guarantee you'll find it insightful. Together we explore the challenges we all face, and practical solutions to help you maintain your own health and well-being. As always, please feel free to share, comment, and rate - and let us know your thoughts on this important topic. ~DrKF Do You Think You Might Be Suffering From Burnout?

When it comes to mitochondrial health, few nutrients have burst onto the bioenergetics stage with quite the impressive force as the postbiotic rock star Urolithin A (UA). On this New Frontiers episode Dr. Chris Rinsch, co-founder of Amazentis / Timeline, shares the incredible scientific journey of UA's discovery and subsequent unfolding of its many benefits, as confirmed by multiple clinical studies. Together, we explore UA's mechanisms of action, including the role of the microbiome, and exciting preliminary research on UA's potential to reverse immune aging. Of course, our conversation wouldn't be complete without discussing the possible role UA may play in slowing down biological aging and extending healthspan - after all mitochondrial decline is one of the hallmarks of aging. Tune in and please leave us a review wherever you listen to New Frontiers. - DrKF Check out the Shownotes for the episode at https://www.drkarafitzgerald.com/fxmed-podcast/,

Did you know that "bone-eating" osteoclast cells are derived from immune cell precursors and are stimulated by inflammation, just like other immune cells? Or that bone has its own glycocalyx whose health is essential to realize the benefits of exercise for bone? Folks, Dr. Keith McCormick is back on New Frontiers with ever-more juicy pearls like these, and with important updates on bone care for functional medicine practitioners and patients alike. Dr. McCormick is living proof that osteoporosis and a history of multiple bone fractures - he had 12 between the ages of 45-50 - are not an irrecoverable life (or death) sentence. In fact, even as he nears 70, Dr. McCormick is out there competing in Ironman and pentathlon events, living his life to the fullest. Dr. McCormick is arguably the top thinker and practitioner on bone health from a systems and functional point of view. His nuanced navigation of diagnostic tools as well as both pharmaceutical and nonpharmaceutical interventions is fully comprehensive and deep. You'll want to tune in to find out how he navigates his patient cases, casting a wide net for underlying contributing factors, his go-to interventions for specific situations, how he doses supplements, and more.

Over 270,000 new cases of breast cancer are diagnosed each year in the US. And while BRCA mutations often get the most press, there are other, potentially more critical factors we can address. Today, Dr. Ruth Hobson joins us to delve into the realm of breast health, shedding light on both modifiable and non-modifiable risk factors, and sharing real-life strategies for supporting our patients. We dive into a range of essential topics, from dietary and lifestyle influences to the ongoing debate around Hormone Replacement Therapy (HRT), and venture into the world of functional tests to evaluate hormones and metabolites crucial for comprehensive breast health. We’ll uncover the intricate connection between gut health and breast health - Did you know that breast tissue has its own microbiome?!? - and examine how inflammation, peripheral fat, and methylation impact cancer risk. Bring a pen and paper, this is a deep dive into the hormones and breast health that you won’t want to miss. ~DrKF

The epigenetic pioneer, Dr. Randy Jirtle, returns to New Frontiers to share his latest groundbreaking work. And I really do mean groundbreaking. Dr. Jirtle's work in mapping our "imprintome" is literally creating a brand new branch of scientific study that is expected to provide valuable insights and opportunities for epigenetially-targeted therapies, including nutrition and lifestyle. What I so appreciate about Dr. Jirtle's work is that it clearly demonstrates how we are not inescapably at the mercy of our genes. Instead, Dr. Jirtle views disease-associated genes as a starting point for the environment to direct its expression. Join me on this episode of New Frontiers to find out what your imprintome actually is, why it is so important, and what you can expect from this area of scientific discovery in the near future. ~DrKF

In this episode, I have the pleasure of interviewing Mark Newman, the president and founder of Precision Analytical, the company behind the revolutionary DUTCH test. Mark is a true pioneer in the field of hormone testing, and in our conversation, we delve into the latest developments in this rapidly evolving field. We discuss how the DUTCH test has expanded to include additional markers, providing even more comprehensive insights into hormone health. During our conversation, we also address the controversy surrounding saliva testing for hormone analysis. Mark sheds light on the limitations of this method and why the DUTCH test offers a more accurate and reliable alternative. I’m sure you’ll find this interview as fascinating as I did, and it will be super helpful for identifying the best forms of hormone testing for your patients. So, without further ado, let’s dive into this enlightening conversation with Mark Newman. ~DrKF

Harvard's award-winning Dr. Charles Serhan isn't just an expert on specialized pro-resolving lipid mediators (SPMs), he is the scientist who actually discovered them. His breakthroughs opened up a brand new field of research and clinical application with immense potential. After all, chronic, unresolved inflammation is a contributor or cause of so many conditions. The growing body of research on the utility of SPMs continues to astound (although when you start to understand the mechanisms, it's perhaps easy to understand some of the "why") - pain, rheumatoid, osteo- and Lyme arthritis, macular degeneration, periodontal disease, uveitis, surgical recovery, and repetitive head injury, for instance, have all been shown to be potentially benefited by the ability of SPMs to promote inflammation resolution. Clinically, I consider SPMs in all conditions where unresolved inflammation is a contributing factor. Not only that, but SPMs appear to have some rather surprising additional effects including stem cell regulation, tissue regeneration, and inhibition of amyloid-beta peptide in Alzheimer's models (even restoring memory loss in mice). I am honored to host Dr. Serhan here on New Frontiers along with his esteemed colleague, Dr. Megan Sulciner. Dr. Sulciner is a clinician-scientist and resident in the Serhan Lab whose exciting work focuses on advancing postoperative outcomes for surgical patients as well as the role of SPMs in enhancing cancer therapy and preventing cancer metastasis. I’m sure you will love this insightful, tour-de-force conversation! ~DrKF

Vascular health is fundamentally essential to longevity and health span, and that’s why I’m thrilled to be welcoming Dr. Michael Twyman to New Frontiers. Trained as an invasive cardiologist, Dr. Twyman has made the shift to a more preventative approach, moving beyond traditional cath lab results to focus on the health of the 60,000 miles of blood vessels that carry vital blood, oxygen and nutrients to every organ in the body, with hopes of reaching patients before they reach the end stages of disease. In this episode we’ll look at endothelial glycocalyx dysfunction as the root cause of cardiovascular disease, and dive into the key roles of nitric oxide, circadian biology, and the oral microbiome on cardiovascular health. I know you’ll find this interview to be absolutely fascinating. Have a listen and leave me a comment let me know what you think. ~DrKF

I’m so happy to be here with Dr. Vincent Pedre to dig into emerging science on the microbiome. Dr. Pedre shares extensive clinical pearls from his vast experience in functional gut health in an approachable and fun way as he drills down on possible causes of the challenging gut epidemic we clinicians see in the increasing numbers of IBS patients walking through our doors. Dr. Pedre and I discuss how microbial diversity is the holy grail for reducing the risk of chronic disease, and how the gut disruptors of our time, (including food and environmental toxins, chronic stress, our over-sterilized world and lack of time in nature) are leading to many of the health challenges of the day. We get into current science on the impact of a high-fiber vs a diet high in fermented food on microbial diversity and immune activation. And there’s more: we talk about how where we live matters when it comes to our microbiome, the health- or disease-promoting post-biotics that are created, our optimal diet, overall health and our ability to create stress resiliency. It’s a lot -- and I’m sure you’ll be fascinated by Dr. Pedre and find numerous valuable insights to support your patients. Thanks for listening, and please leave me a review wherever you hear my voice. ~DrKF

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
