The Longevity & Lifestyle Podcast

In this episode of the Longevity & Lifestyle Podcast, Claudia von Boeselager sits down with Dr. Alexander Grinberg, one of the few physicians who has worked with peptide therapeutics since the 1980s.
Long before peptides became a social media trend, Dr. Grinberg was involved in clinical research using peptide bioregulators in patients with autoimmune disease, immune dysfunction, radiation exposure, viral illnesses, and regenerative medicine. Drawing on more than 35 years of clinical and scientific experience, he explains what peptides can realistically do, where the evidence is strongest, and why personalized medicine matters far more than following influencer protocols.

They discuss the biggest mistakes people make when self-experimenting with peptides, why proper diagnostics are essential before starting treatment, cancer considerations, mitochondrial health, immune function, bioregulators, GLP-1 medications, and what the future of peptide medicine may look like.

Whether you're curious about BPC-157, GHK-Cu, Epitalon, MOTS-c, SS-31, or simply want to separate scientific evidence from marketing hype, this conversation offers one of the most balanced and informative discussions on peptides available today.

In this episode you'll learn:
Why peptides are far more powerful than most people realize
The biggest risks of self-prescribing peptide protocols
Who should avoid certain peptides altogether
The blood tests and biomarkers to check before starting
Why longevity treatments should always be personalized
The fascinating history of peptide medicine dating back to the 1980s
How peptides may support healthy aging, immune health and regenerative medicine
The future of peptide therapeutics and precision longevity medicine

My guest today is Roger Love - one of the world’s most renowned voice coaches. He has worked with top performers, executives, actors, and public figures, and his work sits at the intersection of voice, confidence, emotional expression, breath, nervous system regulation, communication, and identity. In this conversation, we explore how the way you sound shapes the way people perceive you and the way you perceive yourself.

We get into Roger’s framework for mastering the five core voice variables — pitch, pace, tone, melody, and volume — and why most people unknowingly sound monotone, anxious, apologetic, or less confident than they really are.

He explains how voice patterns influence emotion, why public speaking fear is really fear of judgment, and how changing the sounds of confidence can actually help build confidence in real life.

We also discuss the connection between voice and longevity, Roger’s work using singing and airflow to help people with stuttering and post-stroke speech challenges, and why he believes your voice may be one of the most overlooked tools for improving relationships, self-expression, business, and quality of life.

This episode is for anyone who wants to communicate with more clarity, warmth, authority, and authenticity.

Dr. Darshan Shah is a board-certified surgeon, longevity physician, entrepreneur, and founder of Next Health. After performing more than 20,000 surgeries and training at the Mayo Clinic, Darshan realized something most people never hear from the medical system: treating disease is not the same as creating health.

In this episode, he shares the personal health crisis that changed his life, the longevity pyramid he uses with patients, the key biomarkers and scans to know before disease appears, why muscle and metabolic health matter so much, how toxins and hormone disruption are affecting people earlier than ever, and what hyper-preventive medicine may look like in the years ahead.

Dr. Bilal Chughtai is a board-certified urologist and expert in women’s urinary health, recurrent urinary tract infections, the urinary microbiome, and preventative urology.

In this episode, Claudia speaks with Dr. Chughtai about why bladder health deserves far more attention in the longevity conversation - especially for women dealing with recurrent UTIs, menopause, changing hormones, and the often-overlooked effects urinary health can have on cognition, confidence, intimacy, travel, and quality of life.

They explore why UTIs are so common in women, why they often become more frequent with age, how estrogen loss during menopause changes the bladder environment, and why repeated antibiotic use may not always be the best long-term solution. They also discuss the emerging science of the urinary microbiome, the link between UTIs and neurological symptoms in older adults, and practical tools that may help reduce recurrence and support long-term urinary health.

We discuss:

Why bladder health matters for longevity and healthy aging
Why women are more prone to recurrent UTIs
The connection between menopause, estrogen decline, and bladder health
Why UTIs can sometimes show up as confusion or delirium in older adults
The urinary microbiome and how the science is evolving
The downside of repeated antibiotic use
Cranberry, D-mannose, vaginal estrogen, pelvic floor therapy, and other prevention tools
Practical habits to support urinary health over time

What if sweetness itself isn’t the real problem?
In this episode, Claudia welcomes back Sakiko Reuterskiöld, founder and CEO of NOMOSU, to explore the science of sugar, fructose, fiber, cravings, sweeteners, the microbiome, and metabolic health. Sakiko explains why many people may be blaming the wrong thing when it comes to blood sugar, weight gain, and long-term metabolic dysfunction and why the bigger issue may be excess sugar, especially liquid fructose, low fiber intake, and the structure of modern foods.

They discuss the difference between sweet taste and metabolic harm, why liquid fructose may be especially damaging over time, how fiber supports satiety, insulin sensitivity, and gut health, and what the science really says about stevia, erythritol, cacao, and so-called “healthy” sugars. This episode is especially relevant for anyone who wants better energy, fewer cravings, improved blood sugar control, and a smarter, more science-backed relationship with sweetness.
