Key Takeaways from this Blog:

• Dr. Pamela Smith led a Southend provider session on how chronic stress reaches the mitochondria, the cell’s energy producer.
• Stress drives cortisol through the HPA axis; the mitochondria are both a target and a mediator of that response, linked to inflammation.
• Her framework: a triad of mitochondrial health, adrenal function, and inflammation, supported by diet, movement, sleep, and toxin awareness.

Stress, Cortisol, and Mitochondrial Function: Key Concepts From Our Latest Provider Education Session

Chronic stress wreaks havoc on the body. More specifically, it reaches the mitochondria, the structures inside nearly every cell that produce most of the body’s usable energy, and the downstream effects surface across many of the systems a clinician manages in the form of patient complaints day to day.

That was the throughline of a recent Southend provider education session led by Dr. Pamela Smith, a physician with roughly three decades in functional and personalized medicine, a master’s degree in public health, and a degree in metabolic and nutritional medicine. For the providers who could not join live, here are the concepts worth carrying back to practice.

One note before we start: the material below is educational and reflects Dr. Smith’s independent clinical perspective. It is not medical or legal advice, and it is not a claim about any specific compounded preparation. Compounded medications are not reviewed or verified by the FDA for safety, effectiveness, or quality and are not FDA-approved. Instead, compounded drugs may be prepared, or compounded, for patients who cannot be treated with an FDA-approved medication. In situations like this, compounding can serve important patient needs. A licensed healthcare provider will evaluate if treatment involving a compounded medication is necessary or appropriate for you. 503A pharmacies are required to comply with FDA rules, regulations, and guidance, among other applicable laws, rules, regulations, and guidance.

What is mitochondrial function, and why does it matter clinically?

Mitochondria are the structures inside most cells that generate ATP, the molecule cells use for energy, through a process called oxidative phosphorylation. They carry their own DNA, inherited maternally, and their role goes beyond energy: they help regulate metabolism, participate in programmed cell death, store calcium, and contribute to the synthesis of certain hormones and metabolites.

Because so many tissues depend on mitochondrial output, changes in mitochondrial function tend to appear wherever energy demand is high. Mitochondrial health is a common theme running through longevity, metabolic health, and cognitive and cardiovascular physiology.

How does stress affect the mitochondria?

Stress activates the HPA axis (hypothalamic-pituitary-adrenal), which drives the release of cortisol. Cortisol receptors sit throughout the body, from the nervous and immune systems to the cardiovascular, respiratory, and musculoskeletal systems, which is part of why stress physiology reaches so widely.

Dr. Smith’s central point: the mitochondria are both a target of stress and a mediator of the body’s stress response. Chronic stress has been associated in the research literature Dr. Smith presents with shifts in mitochondrial structure and function and with low-grade inflammation. She also emphasized that cortisol is not the whole story. Other hormones in and around the HPA axis participate in the body’s inflammatory balance.

Dr. Smith and the clinical framework

Dr. Smith focused the talk around a simple triad: mitochondrial health, adrenal function, and inflammation. Her practical takeaways leaned on foundational levers, a Mediterranean-patterned diet rich in fruits and vegetables, movement, sleep, toxin awareness, stress-reduction practices, and attention to methylation status. Where nutrient support enters a plan, Dr. Smith says that the decision belongs to the treating provider and the individual patient in front of them.

The nutrient discussion

Dr. Smith discusses the nutrients NAD+, Glutathione, and Methylcobalamin as a part of the broader clinical discussion during the webinar. Whether any are appropriate for a given patient is a clinical decision for the prescriber.

Why Southend hosts sessions like this

A provider educational webinar is just one of many ways we bring our clinical depth to the provider community, by providing access to industry specialists who are key opinion leaders, practitioners, or a leading authority on the current work in the compounding pharmacy and provider spaces. By holding these sessions, we are able to discuss practical applications that impact our practices and, ultimately, the care providers deliver to their patients.

The connection doesn’t end when the session does. Every practice that works with Southend has a dedicated account manager who knows the account and holds the full order history, and when a question runs past what an account answer can cover, our clinical pharmacy team is there.

Behind that: LegitScript certification, USP 797 adherence, a 55,200 square foot Houston facility, licensure across 40+ states, and onboarding that runs in one business day with first patient orders shipping in three to five business days. One pharmacy for the whole protocol, one account manager, one record.

FAQ

What is mitochondrial function?

Mitochondrial function refers to how well a cell’s mitochondria produce energy (ATP) and carry out their other roles, including metabolic regulation, calcium storage, and programmed cell death.

How does chronic stress affect the mitochondria?

Chronic stress activates the HPA axis and cortisol release, and has been associated in the research literature with changes in mitochondrial structure and function and with low-grade inflammation. In Southend’s provider session, Dr. Pamela Smith described the mitochondria as both a target and a mediator of the stress response.

Does Southend offer ongoing provider education?

Yes. Southend hosts clinical education sessions for providers, like this one with Dr. Pamela Smith. To hear about upcoming sessions, check out southendpharmacy.com under the hub, we have all webinars and upcoming speakers listed.
