OsteoSignal with Neal D. O'Neal, PT

Your muscles don't just shorten when they contract. They twist. This episode uncovers titin, the body's hidden "third filament" that acts like a spring inside every muscle fiber, and explains why some muscles feel impossible to stretch no matter how hard you try.  Join Neal O'Neal, Autumn Mayberry, and Brent Mayberry as they break down why passive stretching often fails, and...

Your body never stops building. Every tendon, ligament, and stretch of fascia forms from metals you eat: iron, copper, zinc, magnesium, selenium, manganese. Miss one, and repair stalls, even when standard bloodwork looks fine. This episode breaks down how each metal shapes the tissue therapists feel under their hands, from doughy fascia that won't spring back to muscles that never fully relax....

Millions of people take GLP-1 drugs like Ozempic and Zepbound to lose weight. Here's what nobody tells them: up to 40% of that weight loss is muscle, not fat. This episode breaks down why. These drugs suppress hunger so hard patients can't eat enough protein, and their bodies start cannibalizing muscle and collagen to survive. The result: sagging skin, "Ozempic face," new joint p...

Your immune cells do more than clean up damage. New research shows macrophages build synapse-like connections with injured muscle fibers, using a protein called PSD95, the same scaffolding protein found at nerve junctions. These cells plug directly into muscle tissue and pump calcium inside, triggering repair. Neal O'Neal and Autumn Mayberry break down what this means in the clinic, including...

Your child isn't addicted to their phone. Their brain might be running on empty. This episode flips the dopamine scrolling story on its head. Neal and Autumn argue that doom scrolling doesn't come from too much dopamine. It comes from too little. Dopamine isn't the pleasure chemical. (That’s serotonin.) Instead, it's the switch that lets you stop one task and start another. When a...

Transcript: https://tinyurl.com/OS033transcript Summary: Your chronic pain patients keep mentioning bloating, reflux, and food sensitivities. That's not a coincidence. This episode of OsteoSignal reveals the biochemical link most manual therapists never learn: your gut runs on four peptides that control far more than digestion. Neal breaks down the "gut peptide quartet": GLP1, GLP2,...

Your hands are chemists. Every touch you deliver as a manual therapist triggers a molecular chain reaction inside your patient's cells. This episode breaks down mechanotransduction: the five-step process that converts physical force into calcium signals, energy production, and tissue healing. You will learn why some patients heal fast while others keep relapsing after the same fascial release....

Iron deficiency and thyroid problems don't announce themselves. Your labs look fine on paper. Your doctor tells you to sleep more and stress less. Meanwhile you're cold all the time and exhausted no matter how much you rest. Neal calls this the Metabolic Triad: iron, thyroid hormone, and mitochondria. These three systems run in a loop. Iron lets your thyroid produce hormones. Thyroid hormo...

Normal blood test, but still exhausted, foggy, or stuck with an injury that won't heal? This episode covers functional iron deficiency: labs look fine, even high, but your muscles, brain, thyroid, and connective tissue are starved for iron. The cause is hepcidin, a liver hormone that locks ferroportin, the "door" iron uses to leave storage and enter your bloodstream. Neal compares it...

Iron deficiency affects far more than blood health. It powers key brain functions most clinicians overlook. Iron drives brain energy production. It fuels the choroid plexus, the structure that makes cerebrospinal fluid. Low iron slows CSF production and weakens the glymphatic system, your brain's overnight cleaning process. The result: brain fog and higher long-term risk of cognitive decline....

A November 2025 study in Nature Communications reveals that bone health starts with biology, not density. Researchers found that chronic, low-grade inflammation reshapes the bone marrow environment years before cancer or leukemia appears. Normal mesenchymal stromal cells, the structural root system of bone marrow, get replaced by inflammatory stromal cells over time. These cells release interferon...

In this episode of the OsteoSignal Podcast, Neal and Autumn pull back the curtain on one of the most overlooked drivers of chronic fatigue, brain fog, poor motivation, and unresolvable musculoskeletal dysfunction: brain iron deficiency — even when your bloodwork looks fine. This episode takes a deep dive into the physiology of iron in the central nervous system and explains why standard hemoglobin...

In this episode of the Osteosignal podcast, we examine the complexities of chronic fatigue, exploring the roles of ferritin, dopamine, and the autonomic nervous system. We discuss how iron deficiency can lead to neurological issues, the concept of central fatigue, and the symptoms of sympathetic dominance. The conversation emphasizes the importance of understanding these physiological processes in...

In this episode of the OsteoSignal podcast, we delve into the complexities of the neuroendocrine axis, focusing on the role of ferritin in fatigue and joint health. We discuss the importance of understanding signs and symptoms in patients, the limitations of standard medical assessments, and how osteopathic manual therapy can bridge the gap between clinical observations and biochemical realities....

In this episode of the Osteosignal podcast, we discuss the critical role of iron physiology in athletic performance and recovery. He emphasizes that iron is not just about anemia; it is essential for oxygen delivery, energy production, and overall endurance. The conversation explores the complexities of iron metabolism, including the importance of ferritin and transferrin, and how factors like inf...

In this episode of the OsteoSignal podcast, we delve into the critical role of iron regulation in health and athletic performance. They discuss the importance of ferritin and transferrin in iron storage and transport, the impact of inflammation on iron availability, and the connection between gut health and iron absorption. The conversation emphasizes the need for a holistic approach to understand...

In this episode of the Osteosignal Podcast, Neal O'Neal and Autumn Mayberry delve into the complexities of the neuroendocrine axis, particularly during pregnancy. They discuss how hormonal changes, especially estrogen and testosterone, can lead to significant emotional and physical changes in expectant mothers. The conversation emphasizes the importance of understanding these changes for bette...

In this episode of the Osteosignal podcast, Neal O'Neal, Autumn Mayberry, and Brent Mayberry delve into the complexities of the neuroendocrine axis, particularly focusing on adrenal disease during pregnancy.
