Brad Currier discusses Urolithin A and Resistance Training Guidelines
Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to Brad Currier, Science Lead at Timeline Nutrition and lead author of the recent American College of Sports Medicine position stand on resistance training.In this episode, the conversation begins with Urolithin A and Mitopure, exploring what it is, what it does in the body, and why it has become an area of interest for mitochondrial health and muscle function. Brad explains the proposed mechanisms, the current human evidence, and what outcomes have actually been shown to improve, from cellular-level changes through to potential real-world benefits.Mikki and Brad also discuss who may be the best fit for a supplement like this, including older adults, athletes, and those already doing the fundamentals well, while also addressing the limitations of the current research and how to think about bias when science and industry intersect.The conversation then shifts to resistance training, where Brad shares key takeaways from the ACSM position stand he led, including what matters most for strength, hypertrophy, and health, and what people can probably stop overthinking.It’s a balanced, evidence-informed conversation about mitochondrial health, supplementation, strength training, and the practical foundations that still matter most.Brad Currier is the Science Lead at Timeline Nutrition, where his work focuses on translating emerging research on mitochondrial health into practical, evidence-based applications. In particular, he has been closely involved in the science and communication around Urolithin A, the active ingredient in Mitopure, and its potential role in supporting muscle function, cellular energy, and healthy ageing.With a background in exercise science and resistance training research, Brad brings a dual lens to his work—combining performance-focused insights with a broader interest in longevity and metabolic health. He has contributed to large-scale evidence syntheses in resistance training, helping clarify what actually matters for strength, hypertrophy, and overall health, and where the field may have overcomplicated things.At Timeline, his role sits at the intersection of research, education, and application, helping bridge the gap between mechanistic science, clinical relevance, and real-world use—particularly as interest grows in interventions that support muscle and mitochondrial function across the lifespan.Brad Currier https://www.instagram.com/bradcurrier.phd/• ACSM Position Stand on Resistance Training (2026) - https://journals.lww.com/acsm-msse/fulltext/2026/04000/american_college_of_sports_medicine_position.21.aspx• Timeline Nutrition - https://www.timeline.com• Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

Mini Mikkipedia - Omega-3 Benefits Beyond Heart and Brain
In this Mini Mikkiepdia episode, Mikki takes a fresh look at omega-3 fatty acids beyond the usual “good for your heart and brain” message. She explores emerging and lesser-known research on omega-3s and their potential role in protecting muscle during immobilisation, supporting fertility and oocyte quality, reducing period pain, improving submaximal exercise efficiency, and possibly influencing dementia and colorectal polyp risk. Mikki also discusses the difference between marine omega-3s like EPA and DHA, and plant-based ALA, including surprising findings in motor neurone disease research. With practical dosing context, cautions around study limitations, and a reminder to consider omega-3 index testing, this episode is a useful listen for active people, women in perimenopause, athletes, and anyone interested in targeted supplementation. Highlights / Topics Covered: How omega-3s may reduce muscle loss during injury, surgery, or immobilisation The role of EPA and DHA in fertility, period pain, and inflammatory pathways Emerging research on omega-3s, APOE4, dementia risk, and brain structure Why athletes may benefit from improved submaximal heart rate and perceived effort Practical dosing considerations and why the omega-3 index matters Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order

The discussion explores the difference between being naturally flexible and having true hypermobility, along with the often-overlooked symptoms like chronic pain, fatigue, and proprioceptive challenges. Melissa explains what’s happening beneath the surface with joint stability and connective tissue, and why traditional approaches to exercise can sometimes do more harm than good.The conversation then shifts into what actually works. From strength training and motor control to pacing, recovery, and rebuilding trust in the body, Melissa shares a clear framework for managing hypermobility safely and effectively. They also touch on the role of muscle mass, nutrition, and daily habits in supporting long-term function.It’s a grounded and reassuring conversation for anyone navigating a body that feels unpredictable, offering both clarity and practical direction.Melissa is a physical therapist with over two decades of experience, specialising in hypermobility, joint pain, and movement rehabilitation. She lives with hypermobile Ehlers-Danlos Syndrome (hEDS) herself, giving her a unique perspective on both the clinical and lived realities of the condition.Originally a nationally competitive level 10 gymnast, Melissa’s flexibility was once a strength but ultimately contributed to a series of injuries, including a career-ending stress fracture in her lower back. Ongoing pain led her to explore different movement modalities, including Pilates, yoga, and strength and conditioning. While each offered benefits, it was the integration of these approaches that proved most effective.Melissa went on to develop the ChimeraFit method, a system that combines elements of Pilates, yoga, strength, and balance training to support people with hypermobility, arthritis, and chronic joint pain. She has been teaching this approach for over 20 years, helping individuals build strength, stability, and confidence in their bodies through safe and effective movement.https://www.instagram.com/dr.melissakoehl.pt/https://www.chimera-health.com/ground-control-september-2026-waitlisthttps://www.chimera-health.com/ Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

Mini Mikkipedia - Can Multivitamins Slow Brain Ageing?
This week’s Mini Mikkipedia takes a closer look at multivitamins, nutrient status, and whether a daily broad-spectrum supplement may support cognitive ageing. Mikki discusses the COSMOS trial, a large randomised, double-blind, placebo-controlled study that examined multivitamin use in older adults, with a particular focus on the cognitive findings from its ancillary studies. While the parent trial did not show significant benefits for cancer or cardiovascular disease, the cognitive studies found consistent benefits for episodic memory, with effects estimated to be equivalent to slowing cognitive ageing by around two to three years. Mikki also unpacks the limitations, including modest effect sizes, population generalisability, supplement formulation, and why supplements should support, not replace, the fundamentals of nutrition, exercise and sleep. Highlights: Why calorie deficits can increase the risk of micronutrient insufficiency What the COSMOS trial tells us about multivitamins and brain ageing The difference between observational research and randomised controlled trials Why episodic memory may be particularly responsive to nutrient status Why supplement quality, nutrient forms, and baseline deficiency risk matter Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order

Rethinking Protein and Plant-Based Health with Dr Matt Nagra
Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to Dr Matt Nagra, a naturopathic doctor and researcher known for his evidence-based perspective on nutrition, with a particular focus on plant-based diets and chronic disease.In this episode, the conversation tackles one of the most debated topics in nutrition right now: protein. Matt helps unpack why protein has become such a focal point, how to interpret the current evidence, and what outcomes actually matter when we’re talking about intake and health. They explore the long-standing protein RDA and what it was designed to represent.The discussion then moves into protein quality, addressing common claims around plant versus animal protein, and why mechanistic research doesn’t always align with long-term health outcomes. Matt also provides important context around dietary patterns and chronic disease risk, helping to separate the role of protein itself from the broader way people eat.They finish with a dive into choline, covering its role in the body, how it interacts with other nutrients like folate and betaine, and what this means for people following predominantly plant-based diets.It’s a thoughtful, nuanced conversation that cuts through the noise and brings clarity to some of the biggest questions in modern nutrition.Dr Matt Nagra is a naturopathic doctor who graduated from the Boucher Institute after completing a Bachelor of Science in Microbiology at the University of Victoria. He holds additional board certifications in prescriptive authority, immunisations, advanced injection therapies, intravenous therapies, and acupuncture. Using an evidence-based approach, he creates individualised treatment protocols tailored to each patient’s health goals and lifestyle.He has a particular passion for plant-based and vegan nutrition, physical medicine, and chronic disease treatment. With additional training in nutrition, he holds a Plant-Based Nutrition Certification from Cornell University and the T. Colin Campbell Center for Nutrition Studies, where he has also authored multiple articles. His work aims to support individuals in thriving on plant-based diets, while bridging the gap between lifestyle-based interventions and medical care.Choline paper: https://www.academia.edu/3067-1345/2/4/10.20935/AcadNutr8085Instagram: @dr.matthewnagraDr. Nagra’s website Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

Mini Mikkipedia - Metabolic Memory: Why Your Body Remembers Everything
In this Mini Mikkipedia episode, Mikki explores the concept of metabolic memory—a powerful and often overlooked driver of long-term health. Drawing on landmark studies like DCCT and UKPDS, she explains how periods of poor metabolic health can leave a lasting imprint, continuing to influence disease risk even after markers like blood glucose are brought back under control. But it’s not all bad news. Mikki also unpacks the flip side: how positive adaptations from training, nutrition, and metabolic challenges can create a beneficial “memory” that helps the body rebound faster and perform better over time. From epigenetics to mitochondrial function, this episode highlights why timing matters and why early intervention—and consistency—can shape your metabolic future. Highlights: What metabolic memory is and where the concept originated The “legacy effect” in diabetes research and why early control matters Cellular mechanisms: epigenetics, oxidative stress, and AGEs The positive side: training, ketosis, and metabolic flexibility Why your past habits—good or bad—continue to influence your health Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order

Don walks through the historical context behind early guidelines, including where things may have gone off track, particularly around the treatment of fat, cholesterol, and protein-rich foods.From there, the discussion moves into the science. Don outlines the limitations of relying heavily on observational nutrition research and contrasts this with findings from controlled trials, particularly in relation to protein requirements and metabolic health. He explains why he recommended a shift to the new protein targets to better support muscle, satiety, and overall health.Dr. Donald Layman is Professor Emeritus in the Department of Food Science & Human Nutrition at the University of Illinois at Urbana-Champaign. Dr. Layman has been a leader in research about protein, nutrition for athletic performance, obesity, diabetes and cardiovascular health. Dr. Layman has over 100 peer-reviewed publications. He has received numerous awards for his research from the American Society for Nutrition and the National Institutes for Health and for his nutrition teaching. Dr. Layman currently serves as Associate Editor of the Journal of Nutrition Education and Behavior and on the editorial boards of Nutrition & Metabolism, and Nutrition Research and Practice.

Mini Mikkipedia - High Protein Diets: What the Evidence Actually Shows
In this Mini Mikkipedia episode, Mikki breaks down one of the most persistent nutrition debates: are high-protein diets actually harmful? Drawing on a recent perspective paper published in the American Journal of Clinical Nutrition, she unpacks common claims around kidney damage, bone loss, diabetes risk, and reduced longevity. Rather than dismissing concerns outright, Mikki walks through what the research truly shows, highlighting key methodological flaws, the limits of observational data, and the importance of context. From overfeeding studies to real-world dietary patterns, this episode challenges headline-driven narratives and brings nuance back into the conversation. If you’ve ever questioned whether your protein intake is “too high,” this is a grounded, evidence-informed discussion to help you cut through the noise and make more confident decisions.Highlights: Why the “protein turns to fat” claim doesn’t hold up in real-world studies The truth about protein intake and kidney health in healthy individuals How higher protein diets impact bone density and fracture risk The nuance behind protein, insulin resistance, and type 2 diabetes Why observational data often misleads protein-related health claims Contact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwillidenNZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzSave 20% on all Nuzest Products WORLDWIDE with the code MIKKI at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comCurranz supplement: MIKKI saves you 25% at www.curranz.co.nz or www.curranz.co.uk off your first order
