What Is DHEA? A Naturopath's Guide to This Often-Overlooked Hormone

You've done the bloodwork. The doctor reviewed your results, said everything looks normal, and sent you on your way. But you still wake up exhausted. Your motivation is flat, your libido has quietly disappeared, and the mental sharpness you used to rely on feels like it belongs to a different version of you. Something is off — and "normal" doesn't quite cover it.

DHEA is one of the hormones that often gets missed in a standard workup. It's not flashy, it doesn't get the same attention as estrogen or testosterone, and yet it serves as the raw material your body uses to produce many of the hormones that shape how you feel every single day. Understanding what DHEA is — and what declining levels may mean for your health — is one of the more important conversations you can have about long-term vitality.

This guide walks you through what DHEA actually does, what research suggests about supplementation, and why a root-cause approach to low DHEA looks very different from simply adding a bottle to your cart.

What Is DHEA — and Why Does It Matter?

DHEA stands for dehydroepiandrosterone. That's a mouthful, so let's set the full name aside and focus on what it actually does.

DHEA is produced primarily by your adrenal glands — two small glands that sit on top of your kidneys and manage your body's response to stress, among many other things. In smaller amounts, it's also produced by the gonads and the brain. Think of DHEA as a master precursor hormone: your body converts it into estrogen, testosterone, and other key hormones depending on what it needs most.

That precursor role is what makes DHEA so significant. It doesn't act in isolation — it feeds a hormonal downstream that touches your energy levels, mood, libido, immune resilience, bone density, and metabolic health. When DHEA is in good supply and your body is converting it appropriately, many systems tend to hum along with it. When DHEA is low, those downstream effects can show up as symptoms that are easy to dismiss or misattribute — fatigue, hormonal fog, reduced drive, slower recovery.

A simple analogy: if your hormonal ecosystem were a river, DHEA would be one of the primary tributaries feeding it. You can't fully understand why the river is running low by looking only at the main channel.

How DHEA Levels Change Over Time

DHEA production typically peaks in your mid-20s. From your 30s onward, levels begin a gradual, natural decline — roughly 2–3% per year. By the time most people reach their 70s, DHEA levels may be only 20–30% of what they were at their peak.

That's a normal part of aging. But what's less commonly discussed is how quickly that decline can accelerate when certain lifestyle and physiological factors are in play:

• Chronic stress — Sustained activation of the stress response draws heavily on adrenal resources, and DHEA production often bears the cost.
• Poor or disrupted sleep — Much of the body's hormonal repair and production happens overnight. Chronic sleep deprivation can suppress adrenal function over time.
• Nutritional gaps — Key micronutrients support adrenal health; deficiencies can blunt hormone production.
• HPA axis dysregulation — The hypothalamic-pituitary-adrenal (HPA) axis is the command center for stress hormone output. When this system becomes dysregulated — as it often does in high-stress, high-demand modern life — DHEA production can suffer.

From a root-cause perspective, this matters because declining DHEA isn't always simply a function of aging. Sometimes it's a signal that your body has been under a burden — and that burden deserves attention alongside any supplement consideration.

What Does Research Suggest About DHEA Supplementation?

DHEA has been studied more extensively than many people realize, with research published in peer-reviewed literature touching on a range of applications. Here's an honest, balanced overview of what the science suggests — and where it remains limited.

Areas where research shows the most promise:

• Hormonal support in postmenopausal women — Multiple randomized controlled trials suggest DHEA supplementation may support estrogen and testosterone levels in postmenopausal women, with some participants reporting improvements in libido, mood, and energy.
• Adrenal support — Research suggests DHEA-S (the sulfated, stored form of DHEA) may serve as a meaningful marker of adrenal reserve, and that supplementation may support adrenal function in individuals with documented insufficiency.
• Cognitive function — Some studies indicate DHEA may play a role in brain health and cognitive resilience, particularly as levels decline with age, though results are not uniform across all populations.
• Immune regulation — Preliminary research suggests DHEA may support immune system balance, though this area requires more investigation.
• Libido and sexual function — Research in both men and women suggests DHEA may support sexual interest and function, though individual responses vary considerably.

Where the evidence is more nuanced:

Results across DHEA studies vary significantly depending on the individual's baseline DHEA-S levels, the dose used, the duration of supplementation, and the population studied. What works meaningfully for someone with documented low DHEA-S may produce little noticeable effect in someone whose levels are already adequate. This is precisely why supplementing without first understanding your baseline is a limited strategy.

DHEA and Adrenal Fatigue — Is There a Connection?

Adrenal fatigue is a term you may have heard — and it's one that conventional medicine tends to dismiss, while many naturopathic practitioners observe patterns in their patients that align with what the term describes: an adrenal system that has been chronically over-demanded and is now underperforming.

DHEA-S, the primary circulating form of DHEA, is sometimes used in naturopathic and functional assessments as a marker of adrenal reserve. When someone has been running on stress hormones for an extended period — whether due to demanding work, relational strain, illness, or poor sleep — DHEA production may decline alongside other markers of adrenal health.

This is where the root-cause lens becomes important. If your DHEA is low because your HPA axis has been chronically dysregulated, simply adding a DHEA supplement addresses the output — but not the input. The ongoing stress load, sleep disruption, or nutritional gaps that led to the depletion are still present. Supporting those underlying factors alongside targeted supplementation tends to produce more sustainable results than supplementation alone.

Conventional medicine often doesn't include DHEA-S in standard fatigue workups, which means many patients are navigating patterns of exhaustion, hormonal fog, and reduced resilience without a full picture of what may be driving them. A more complete assessment — one that looks at adrenal markers, lifestyle context, and the whole person — can change what the path forward looks like.

DHEA for Men — What the Research Suggests

For men navigating declining energy, reduced drive, or slower recovery, DHEA often deserves a closer look. As a testosterone precursor, DHEA contributes to the body's androgen supply — and while supplementing DHEA doesn't automatically translate to a dramatic increase in testosterone, research suggests it may support hormonal balance in men with documented low DHEA-S levels.

What research has explored:

• Libido and sexual function — Several studies suggest DHEA supplementation may support sexual interest and function in men with low baseline DHEA-S levels. Research indicates it may support libido for some men, particularly when low DHEA is part of the hormonal picture — though individual responses vary.
• Energy and vitality — Some research suggests men with higher DHEA-S levels may have better metabolic health markers and self-reported vitality, though causation is complex.
• Muscle recovery and physical performance — Some preliminary evidence suggests DHEA may play a supporting role in lean body composition and recovery, though results are not consistent across all studies.

On dosage for men: Research studies have used a wide range — from 25 mg to 100 mg daily — making a single universal recommendation difficult and, frankly, not appropriate without knowing your individual baseline. DHEA-S testing before supplementing gives you context that a general guideline cannot. A personalized functional consultation can help you understand what your DHEA levels actually mean for your health goals.

DHEA for Women — Hormonal Support Through Perimenopause and Beyond

For women, DHEA's role in estrogen and testosterone production makes it a meaningful part of the hormonal conversation — especially as perimenopause approaches and the ovaries begin reducing their own hormone output. During this transition, the adrenal glands become a more significant source of sex hormone precursors, and DHEA becomes correspondingly more relevant.

Declining DHEA in women may present as:

• Persistent fatigue that doesn't resolve with rest
• Mood shifts, irritability, or emotional flatness
• Reduced libido or physical discomfort
• Cognitive fog or difficulty concentrating
• Decreased sense of overall well-being

Research in postmenopausal women has produced some of the most substantive DHEA data available. Several well-designed studies suggest DHEA supplementation may support hormonal balance, libido, and mood in women with documented low levels — though, again, baseline testing and individual context shape what's appropriate.

Research suggests DHEA may be well-tolerated at appropriate doses in women, but higher doses have been associated with androgenic effects (such as acne or changes in hair) in some individuals. This is another reason that working with a practitioner rather than self-dosing based on general guidelines tends to produce safer, more targeted outcomes.

How to Take DHEA — Timing, Dosage, and What to Know First

Timing: DHEA is commonly suggested to be taken in the morning, as this more closely mirrors the body's natural cortisol and adrenal rhythm — both of which tend to be higher in the first half of the day. Taking it with food may also help with absorption. That said, timing recommendations vary in the literature, and individual response matters.

Dosage: Research studies have used a wide range of doses depending on the population and health focus. Lower doses (5–25 mg) are sometimes appropriate as a starting point, particularly for women, while some men's health studies have used 50 mg or higher. The key variable that the general dosage conversation can't account for is your DHEA-S level — which is exactly why testing before supplementing is worth prioritizing.

Stacking DHEA with ashwagandha: This is a reasonable question. Ashwagandha is an adaptogenic herb with research support for supporting HPA axis function and modulating the stress response. Since HPA axis dysregulation is often a contributing factor to depleted DHEA, combining DHEA supplementation with adaptogenic support may be a complementary approach for some individuals. There are no well-documented negative interactions between the two, but as with any supplement protocol, individual context matters — and a practitioner-guided approach will serve you better than experimenting independently.

Before you start: Testing your DHEA-S baseline gives you the context to supplement meaningfully rather than blindly. Knowing where you are before you begin also helps you assess whether supplementation is making a difference over time.

What to Look for in a Quality DHEA Supplement

The supplement market is crowded, and DHEA quality varies considerably. A few things worth understanding when evaluating a product:

Micronized DHEA: Micronized formulations use smaller particle sizes to support better absorption. Some research suggests micronized DHEA may be more bioavailable than standard formulations, which can matter at lower doses.

Third-party testing: Quality DHEA supplements are third-party tested for potency and purity — meaning an independent lab has verified that what's on the label is actually in the bottle, and that contaminants aren't. This matters more than most people realize in a category where label accuracy isn't federally guaranteed in the same way pharmaceuticals are.

Clean sourcing and minimal fillers: Look for products free from unnecessary binders, artificial colors, and common allergens. Simpler formulas tend to be easier to assess and better tolerated.

Practitioner-grade vs. retail: Practitioner-grade supplements are formulated with bioavailability and clinical application in mind. They may cost more than mass-retail options, but in a category where dose precision and purity matter, the distinction is meaningful.

The Root-Cause Approach to Hormonal Health

DHEA is one piece of a much larger hormonal picture. Understanding your DHEA-S level is useful — but understanding why it is where it is, and what else in your body's interconnected system may be contributing to how you feel, is where meaningful, lasting change tends to begin.

A comprehensive naturopathic hormonal assessment might explore:

• Functional lab work that goes beyond a standard hormone panel
• Adrenal and HPA axis function
• Stress load, sleep quality, and lifestyle patterns driving depletion
• Genetic factors that influence how you produce and metabolize hormones — including insights available through Boro Gene Mapping™
• Nutritional status and gut health as foundational factors in hormone conversion

Dr. Suzanna Underwood — a former nurse with conventional clinical experience who intentionally chose traditional naturopathic training outside the conventional licensing framework — brings a uniquely layered perspective to hormonal health. Her approach doesn't begin with a supplement recommendation. It begins with understanding the full pattern: your history, your labs, your lifestyle, and the interconnected system your body actually is.

Your body was intelligently designed with its own hormonal ecosystem. Supporting it well means understanding it well — not just adding to it and hoping for the best.

If you're ready to look at your hormonal health through a more complete lens, Boro Holistic Health's membership-based care model offers personalized, root-cause support in a private practice setting — outside the insurance-based model and the time constraints that come with it.
