Longevity Optimization with Kayla Barnes-Lentz

We're back with Dr. Szal! Today we are discussing a variety of topics: Gut health, peptides, hormone health , GLP-1's, bone health and so much more!In this conversation, Dr. Sara G dives into the gut-brain connection and explains how disrupting the microbiome can directly affect mood, anxiety, and overall mental resilience. She breaks down why even a single course of antibiotics can shift the balance of your gut in ways most people never consider, and what that means for how you feel day to day.This is where the gut-brain connection becomes practical, not theoretical. Instead of treating symptoms in isolation, understanding how the microbiome regulates neurotransmitters and inflammation changes the way these issues are approached.Rebuilding that system requires more than random probiotics or diet changes. The Weed, Seed, Feed framework focuses on restoring gut balance in the right order, removing what doesn’t belong, reintroducing beneficial bacteria, and supporting their growth long-term.This episode is sponsored by Zen Basil. Their certified edible basil seeds are designed for human nutrition, deliver 15g of fiber per serving, and are batch-tested for glyphosate and over 400 pesticides.

Bérénice Benayoun, PhD, explains why ovarian aging may be one of the earliest and most important drivers of female aging, influencing the brain, immune system, metabolism, and long-term disease risk far beyond reproduction. She breaks down what we actually know so far, including DNA damage, mitochondrial dysfunction, fibrosis, hormonal signaling, and why the ovary appears to age faster than other tissues.
We also get into one of the most surprising findings in the field right now: a brand new study from her lab found that post-reproductive gut microbiota unexpectedly improved ovarian reserve and lowered inflammatory signals in young mice, raising a completely new set of questions about the gut-ovary connection and what may eventually be possible for ovarian health.

Most people can feel when stress is affecting them. Far fewer know whether their body is adapting well or quietly being pushed toward dysfunction.
In this episode, Dr. Deb Rivera, PhD in neuroengineering, explains the hidden biological system that helps determine how well your body handles stress. Her research focuses on redox balance and the glutathione ratio, a biomarker that may reveal whether your body is adapting to stress or slowly moving toward dysfunction.

Brain health problems rarely begin where most people look. Memory issues, low mood, poor focus, anxiety, and even early cognitive decline can be driven by hidden inflammation and root-cause imbalances long before they show up the way most people expect.
In this episode, Dr. Eboni Cornish explains how chronic infections, mold, toxins, hormones, gut dysfunction, and oral or nasal microbial imbalances can all affect the brain, and why “mental health” often needs to be approached as brain health first.
She also shares how tools like brain imaging, inflammation markers, and functional testing can uncover patterns that are often missed in standard workups, while outlining the core foundations that support long-term brain health, including sleep, exercise, omega-3s, vitamin D, hormone balance, gut health, and detox capacity.
