    Harvard MD: The Truth About Peptides And Longevity Medicine

    Harvard MD: The Peptide Boom Is Here.. But Is Medicine Ready? In this episode of Return on Health, Niko and Miguel speak with Dr. Anand Vinjamoori, Harvard Medical School and Harvard Business School trained physician, former founding Chief Medical Officer at Modern Age, advisor to Superpower, and founder of Next Generation Medicine. Together, they discuss why longevity medicine is booming while many companies still struggle to build sustainable businesses, why peptides may become one of the next major waves in health optimization, and why the future of biomarkers will likely require a much more individualized and data-driven approach. This episode covers: The peptide boom and why it mattersWhy longevity businesses often failWhat biomarkers can and cannot tell us Dr. Anand explains why the current medical evidence system may be too slow for the next generation of therapies, how real-world data and patient registries could help close the evidence gap, and why biomarkers should be used with nuance rather than treated as absolute truth. He also shares his view on overhyped interventions, the role of exercise, and the cultural differences between American optimization culture and European lifestyle rhythms.

    Geriatrician: Most Aging Is Preventable (But We Start Too Late)

    Most people think aging is something that happens later. In reality, the processes that determine how you age — and whether you stay functional — start decades earlier. In this episode of Return on Health, we sit down with Roberta Vella Azzopardi, a geriatrician and geroscientist with a PhD in cognitive frailty, to break down what aging actually looks like in clinical practice. Instead of focusing on single diseases, this conversation zooms out: Why do people lose independence? What really drives decline? And where are the biggest missed opportunities in prevention? What this episode covers Why modern medicine often intervenes too lateWhat frailty really means — and why it matters more than ageHow loss of muscle drives metabolic and cognitive declineThe concept of peak span and why function beats lifespanWhy hearing loss is one of the biggest overlooked dementia risk factorsThe massive gap in menopause and women’s health careWhat actually works vs. what’s just hype in longevityKey takeaways Frailty is best understood as loss of physiological reserves.When those reserves drop below a certain threshold, even small stressors can lead to long-term decline. This is why two people at the same age can look completely different clinically — one independent, one dependent. A major driver of this process is muscle loss.Muscle is not just about movement. It directly affects metabolic health, insulin sensitivity, and even brain function. The good news: even later in life, resistance training and sufficient protein intake can still improve outcomes. One of the most underestimated risk factors discussed in this episode is hearing loss.It contributes to cognitive decline through increased cognitive load, social isolation, and shared vascular mechanisms — yet remains widely underdiagnosed and undertreated. Another critical blind spot is women’s health, especially around menopause.Many symptoms are treated in isolation instead of addressing underlying hormonal changes, leading to years of missed intervention opportunities.

    Karolinska MD PhD: The Hidden Phase Before Disease

    Karolinska MD PhD: You Feel Healthy. Your Data Disagrees Most people think they’re healthy. But biology doesn’t care how you feel. Long before symptoms show up, your physiology is already shifting.. and most check-ups won’t catch it. In this episode, we sit down with Natalia Trpchevska (MD, PhD Karolinska, Medical & Scientific Director at AYUN) to break down what longevity medicine actually looks like when applied properly. We go beyond surface-level optimization and talk about what actually drives risk: mitochondria, metabolic flexibility, genetics, and why most people are already off track without knowing it. This episode covers: Why longevity medicine still struggles in practiceMitochondria, NAD+ and optimization mythsBiohacking and the future of healthcare Key takeaways: Health declines silently — symptoms come lateLongevity medicine asks: where are you heading biologically?The basics still dominate outcomes — most people underestimate themThe next level is personalization, not more hacksTwo “healthy” people can have completely different risksMitochondria adapt first — then they start driving dysfunctionMost mitochondrial interventions are misunderstoodGenetics gives probabilities, not certaintyReal optimization = prioritization + sequencing About Natalia: Natalia Trpchevska is a medical doctor and holds a PhD in genetics from the Karolinska Institutet. She is the Medical & Scientific Director at AYUN in Zurich, where she focuses on applying systems biology and layered diagnostics to detect early shifts in physiology — before disease develops. Her work bridges clinical medicine and research, with a strong emphasis on translating complex biology into actionable interventions.

    Stanford-Trained MD: Do This to Prevent Chronic Disease

    This episode digs into why midlife health quietly shapes your future more than most people realize - and why the healthcare system is structurally bad at dealing with that phase of life. Together with Stanford-trained MD Ali Zaidi, we talk about what actually changes in your body during midlife, which signals people tend to miss, and where medicine often reacts too late instead of setting the right defaults early on. A grounded conversation about biology, behavior, and why “doing nothing until something breaks” is still the dominant strategy in most health systems. Takeaways Midlife health is crucialPreventive care is undervalued in the healthcare system Longevity interventionsTesting for mid-lifers Chapters 00:00 The Importance of Midlife Health06:02 Physiological Changes in Midlife19:02 Personal Health Stories and Biases28:10 Experimental Approaches in Healthcare36:18 Exploring Red Light Therapy and Vision Health Follow Ali:https://www.linkedin.com/in/ali-zaidi-4a81121/https://www.alizaidimd.com/ More about Return on Health: https://returnonhealth.de/ Niko: https://www.linkedin.com/in/niko-hems/ https://www.instagram.com/niko_hems https://nikohems.de/ Miguel: https://www.linkedin.com/in/miguel-medina-stanivukovic-857b9720b/ https://www.instagram.com/miguelmedinastanivukovic/?hl=en

    What is Return on Health?

    In our first episode, we explain why this podcast exists. We talk about how Miguel and Niko met during their Master’s at NOVA SBE, how endless late-night debates about health, medicine, and broken incentives slowly turned into a shared frustration with the system - and why starting this podcast became the only logical step. We break down what “Return on Health” actually means: why most health decisions optimize for short-term comfort, not long-term outcomes;why good intentions fail when incentives are misaligned;and why prevention, incentives, and system design matter more than hacks and biohacking trends.You’ll get a clear sense of: what we will challenge on this podcastwho this is for (founders, operators, builders, and anyone tired of health content that oversimplifies reality)how we’ll approach topics: data-driven, critical, open to uncertaintywhy we will talk to people we disagree withand why some “promising” health ideas never get good evidence — and what to do with that reality More about Return on Health: https://returnonhealth.de/ Niko: https://www.linkedin.com/in/niko-hems/ https://www.instagram.com/niko_hems https://nikohems.de/ Miguel: https://www.linkedin.com/in/miguel-medina-stanivukovic-857b9720b/ https://www.instagram.com/miguelmedinastanivukovic/?hl=en
