What are bacteriophages? Bacteriophages, or phages, are viruses that infect bacteria. Some multiply inside a matching bacterial cell, then break it open in a process called lysis.

Dr. David Jernigan of Biologix Center for Optimum Health in Franklin, Tennessee, explains how this process works and raises a bigger question: what happens after the bacteria are killed?

This Short explores the phage life cycle and why recovery can also involve addressing damage left behind by illness.

Why would a therapy involve viruses?

Start with this surprising detail: bacteria can get infected, too. The viruses that infect bacteria are called bacteriophages, or phages.

In this BRMI webinar excerpt, Dr. David Jernigan of Biologix Center for Optimum Health in Franklin, Tennessee, introduces INPT—Induced Native Phage Therapy.

He describes a proposed approach focused on stimulating “native” phages: phages already present in the body.

Understanding what these viruses do is the first step toward understanding the conversation about INPT.

What are bacteriophages? Bacteriophages, also called phages, are viruses that infect bacteria and use bacterial cells to reproduce. Some phages destroy their bacterial hosts during this process.

In this clip from the Take Back My Brain podcast, Dr. David Jernigan explains the relationship between phages and bacteria and discusses antibiotic resistance.

Dr. Jernigan is the founder of Biologix Center for Optimum Health in Franklin, Tennessee. His full conversation with host Laurie Hammer also explores the development of Induced Native Phage Therapy (INPT) and his perspective on complex chronic illness.

For Dr. David Jernigan, the search for answers was personal.
Helping his wife through years of chronic illness became a driving force behind his work.

In this episode of Take Back My Brain, Biologix Center’s Dr. Jernigan joins Laurie Hammer to share that story and discuss the development of Induced Native Phage Therapy (INPT).

Their conversation explores antibiotic resistance, naturally occurring phages, and how he distinguishes his approach from conventional phage therapy. He also reflects on the experiences with complex chronic illness that continue to shape his work.

Longevity is more than a number.

The more meaningful measure is healthspan the years of life spent with the physical capacity, cognitive function, energy, and resilience to live fully.

This changes the conversation around health.

Instead of focusing exclusively on the presence or absence of disease, we can look more deeply at how the body is functioning today and how well its systems are equipped to adapt, recover, and perform over time.

At Biologix Center for Optimum Health, our approach considers the body as an interconnected biological system, with the goal of understanding the individual rather than isolating a single symptom.

For some, that journey begins with recovery from complex illness.

For others, it begins from a place of health with the desire to preserve it, strengthen it, and explore a greater level of function.

The goal is not simply more years.
It’s greater potential within them.

The conversation around aging is changing.

The goal isn't simply to extend lifespan. Increasingly, attention is turning toward healthspan the portion of life spent with the physical function, cognitive capacity, resilience, and independence to live well.

Healthy aging begins long before we consider ourselves “old.”

Sleep. Metabolic health. Nutrition. Movement. Cognitive health. Relationships. Stress. Environment. Biological function.

The patterns established across decades can influence how we experience the years ahead.

At Biologix Center for Optimum Health, we're interested in a more meaningful question than simply how long someone might live:

How can we support the body's ability to function well throughout those years?

September is Healthy Aging Month.

Let's make longevity about more than adding years.

Let's pursue more life within them.

Prostate health is an important part of the longevity conversation for men.

Age is one of the strongest risk factors for prostate cancer, which makes appropriate screening and informed conversations with your healthcare provider increasingly important over time.

Proactive health isn't about waiting for symptoms to create urgency.

It's about understanding personal risk, paying attention to changes, using appropriate screening tools, and making informed decisions with your healthcare team.

The goal of longevity is not simply reaching an older age.

It's protecting the health, function, and independence that allow those additional years to be lived fully.

This Prostate Cancer Awareness Month, consider a simple question:

Is prostate health part of your long-term health strategy?
