In this episode, Dr. Mark Holthouse joins Dr. Jaclyn Smeaton and DUTCH founder Mark Newman to take a closer look at a recent peer-reviewed publication from Precision Analytical, Inc. in Frontiers in Reproductive Health, examining how different testing methods hold up when it comes to monitoring male TRT in clinical practice.

Their discussion also covers:

• Common misconceptions about how creams and gels show up in saliva testing and why the numbers can be misleading
• What the clinical data actually shows about dosing accuracy across different testing modalities 
• When to use serum, urine, and other testing approaches can be leveraged to optimize treatment.
• How under or overdosing risks can be reduced by matching the right test to the right clinical question
• Why advancing best practices in integrative medicine requires continually revisiting what the evidence supports

Join us for this episode with Dr. Jenn Simmons, an integrative breast surgeon and oncologist, alongside host Dr. Jaclyn Smeaton and DUTCH founder Mark Newman. This conversation deepens the discussion from a previous episode on hormones and breast cancer risk, challenging widely held clinical assumptions rooted in the Women's Health Initiative (WHI) study. 

This episode also explores: 

• The critical distinction between progestins and progesterone 
• The role of metabolic dysfunction in cancer development 
• Breast cancer as a disease of hormone deficiency, particularly progesterone deficiency, rather than hormone excess 
• The impact of estrogen metabolism, especially the 4-hydroxy pathway, and how the DUTCH Test can provide insight into these pathways 
• Individualized hormone therapy for breast cancer survivors

In this episode, Dr. Asare Christian and Dr. Jaclyn Smeaton discuss female longevity and health span. Dr. Christian brings his unique perspective as a former pain specialist who discovered that many of the chronic conditions he was treating were rooted in hormone imbalance.

This episode also highlights:

·       Three main factors that can contribute to women living longer

·       The protective qualities of estrogen as well as the effects of its decline during perimenopause

·       The importance of testing early and getting baseline hormone levels before symptoms appear

·       How the DUTCH Test provides a picture of hormone metabolism, leading to clarity around estrogen metabolites, the HPA axis, and more

·       Treating the hormonal root cause rather than prescribing medications for each symptom

In this episode, Dr. Jaclyn Smeaton and Dr. Donielle Wilson discuss Dr. Donielle’s clinical philosophy, research findings, and personal journey around understanding and treating stress. 

Their discussion also covers: 

• The stress response and how it’s highly individualized, shaped by genetics, and impacted by prior stress exposure 
• How standard cortisol testing misses most of the cortisol picture 
• Chronic stress and its cascade to multiple body systems, including the reproductive system in women 
• The five clinical stress patterns practitioners should be aware of 
• Small, consistent actions toward stress recovery, like mindfulness and deep breathing, can make a big difference

In this episode, Dr. Jaclyn Smeaton sits down with Dr. Bryant Esquejo, ND to unpack acne through a functional medicine lens, moving far beyond the surface to explore what’s really happening inside the body.

 Dr. Esquejo and Dr. Smeaton also discuss:  

• Acne as not just a skin condition, but a reflection of imbalances involving hormones, blood sugar, inflammation, and the gut microbiome 
• The science behind acne development, from bacterial activity and oil production to deeper drivers like insulin resistance, androgen metabolism, and chronic inflammation 
• The influence of diet, stress, sleep, and gut health 
• How advanced testing, like hormone metabolite analysis, can reveal hidden imbalances in the body 
• Treating acne as an opportunity to better understand and optimize whole-body health

In this episode, Dr. Jaclyn Smeaton and DUTCH Founder Mark Newman discuss a case study published in Integrative Medicine: A Clinician’s Journal in which Mark himself was the patient. The case covers the step-by-step hormonal and metabolic effects of using HCG to boost endogenous testosterone, revealing how increasing testosterone can cascade into elevated estrogen, impaired estrogen clearance, and strained methylation capacity. 

Their conversation also highlights: 

• The benefits of combining serum testing and DUTCH testing to monitor dosing as well as metabolism, clearance, and methylation 
• How methylation is affected by raising testosterone 
• The value of tracking step-by-step supplementation plans with repeated testing 
• The importance of baseline testing before beginning testosterone therapy 
• An upcoming research publication that compares hormone testing methods for testosterone monitoring
