Oxidative stress is a key driver of metabolic health, immune function, inflammation, and hormone signaling, and it impacts nearly every system in the body.

Across the lifespan, from the menstrual cycle through perimenopause and beyond, it shapes how hormones behave and how we interpret testing. When we understand these connections, we can move beyond isolated lab values to a more complete physiologic picture.

With targeted nutrition, lifestyle strategies, stress management, movement, and hormone therapy (when appropriate), we can reduce oxidative burden and support healthier aging. On the DUTCH Test, oxidative stress appears in hormone metabolism patterns, cortisol rhythms, and markers of how the body processes stress.

We’re diving deeper into oxidative stress, hormone imbalance, and immune dysfunction in this week’s webinar.

Sleep is one of the most powerful tools we have for protecting brain health. 🧠

In this episode of The DUTCH Podcast, .heathersandison joins .jaclynsmeaton to talk about how we need to approach brain health with the complexity that the brain deserves. Together, they cover the link between infections like Lyme disease, shingles, and COVID-19 and cognitive decline as well as tips for early intervention, including sleep hygiene, diet, exercise, and stress management.

Our latest peer-reviewed research on TRT monitoring followed the data, not assumptions. The takeaway? Serum testing outperforms saliva for patients using transdermal testosterone.

For years, elevated saliva levels were thought to reflect real tissue impact. But across 100+ studies, clinical outcomes consistently tracked with serum, not saliva.

What this means:
➡️ Serum = primary tool for TRT monitoring
➡️ DUTCH = powerful complement for the bigger hormone picture

Clarity matters. And so does getting it right for patients.

Brain health isn’t one-dimensional, so why treat it that way? 🧠

In this week’s episode of The DUTCH Podcast, .heathersandison and .jaclynsmeaton unpack the underlying drivers of cognitive decline and Alzheimer’s, explore how naturopathic care takes a different approach than conventional medicine, and share actionable ways to support your brain at every stage of life.

This episode also highlights:
- How infections like Lyme disease, shingles, and COVID-19 can be linked to cognitive decline
- Using genetics to inform and optimize early intervention strategies

Don’t miss this upcoming conversation with and Dr. Allison Smith, ND on Thursday, 4/23, at 12pm PST as they dive into the often overlooked role of androgens in everyday health. From low energy to reduced resilience and shifts in aging patterns, androgen imbalance can show up in ways that are easy to miss, but impactful when addressed.

In this webinar, they’ll break down the essentials of androgen physiology and share practical, clinical insights you can start using right away to better support your patients’ vitality, stress response, and long-term health.

Here’s what you’ll explore:
- How androgens function across the body, including key differences in how levels change with age in men and women
- Using DUTCH Test data to guide personalized care, illustrated through real patient cases
- Commonly used therapeutic approaches, including hormonal and non-hormonal strategies, within a functional medicine framework

Blood sugar 🤝 breakouts

In this episode of The DUTCH Podcast, .bryant joins to talk about the different causes and triggers of acne. Together, they discuss how acne is not just a skin condition, but a reflection of imbalances involving hormones, blood sugar, inflammation, and the gut microbiome.

A personalized approach to acne care isn’t just about clearer skin, it’s a pathway to supporting whole-body health.

Your acne might be telling a deeper story.

In this week’s episode of The DUTCH Podcast, sits down with .bryant to take a root cause approach to acne through a functional medicine lens. Together they move far beyond the surface to explore what’s really happening inside the body. They also discuss how acne is a reflection of imbalances involving hormones, blood sugar, inflammation, and the gut microbiome.

New peer-reviewed research from our team takes a closer look at TRT monitoring, specifically comparing serum, saliva, and, to a lesser extent, urine testing in patients using transdermal testosterone.

We approached this analysis without assumptions, following the clinical data wherever it led. The conclusion is clear: serum testing should be prioritized over saliva for TRT monitoring in this context.

Here’s why:
While saliva testing often shows markedly elevated testosterone levels with transdermal delivery, these values do not correlate with clinical outcomes. Across 100+ studies, patient response, including symptom improvement and therapeutic effect, consistently aligned with serum levels, not saliva. We found no evidence that saliva values predicted clinical impact beyond what serum already indicated.

Clinical takeaway:
- Serum remains the most reliable primary tool for TRT monitoring
- DUTCH testing can serve as a valuable complement for broader hormonal insight
- Elevated saliva values with transdermal TRT should be interpreted with caution

We believe this adds important clarity to a long-standing debate and helps support more evidence-aligned decision-making in practice.

Did you know that the DUTCH Test can also be used to assess skin concerns?

Total androgen levels, androgen metabolism, the cortisol picture, and organic acid markers all tell us about the drivers for skin problems. Factors beyond DUTCH testing that influence skin health include skin barrier function, medications, genetics, food sensitivity, thyroid function, nutrient status, the microbiome, and more.

No matter the skin condition, the underlying cause, or the treatment strategy, treating skin conditions starts with addressing the skin barrier. As the skin barrier heals, triggers may make themselves more apparent, and the clinical picture becomes clearer. DUTCH testing is a useful tool for assessing contributing factors to skin conditions, even when the outcome is a normal test result that allows you to rule out the primary suspects.

Guesswork isn’t a strategy… but testing is.

In this week’s episode of The DUTCH Podcast, Mark Newman and 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.

In this episode, they also explore:
- Why combining serum labs with DUTCH testing gives a more complete picture of hormone balance
- What happens to methylation when testosterone levels rise
- A sneak peek at upcoming research comparing hormone testing methods for tracking testosterone
