A 52-year-old woman walks into the office with a DHEA-S of 38 mcg/dL. She has been on 50 mg of over-the-counter DHEA for the past six months because a podcast told her it would help with energy. She feels marginally better, but she is also developing chin hair, her sleep is worse than when she started, and her hairline has thinned along the part. The bottle is from Amazon. Nobody ever drew a lab. Nobody ever told her that 50 mg is roughly five to ten times what most women her age actually need.
DHEA is one of the most widely supplemented and most poorly dosed hormones in the supplement aisle. It is also one of the most useful tools I have when used correctly — and one of the easiest to get wrong. The conversation I want to have here is the dosing conversation. Not the "should I take DHEA" conversation, which is downstream of the lab work, but the "if you do, what does competent dosing actually look like" conversation that almost nobody is having with patients in middle Georgia or anywhere else.
What DHEA actually does in the body
DHEA — dehydroepiandrosterone — is the most abundant steroid hormone in the bloodstream. It is produced primarily by the zona reticularis of the adrenal cortex, with smaller contributions from the gonads and the brain. In circulation, most of it exists as DHEA-sulfate (DHEA-S), which has a longer half-life and is the form we measure on labs.
DHEA's job is to serve as a precursor pool. It is converted in peripheral tissues into androgens (androstenedione, testosterone) and to a smaller degree into estrogens (estradiol, estrone) depending on the local enzymatic environment. In a 50-year-old woman, the adrenal contribution to circulating testosterone becomes proportionally larger as ovarian production drops, and DHEA is the substrate that contribution depends on. DHEA also has independent effects: it modulates the GABA-A receptor system, supports immune function, influences mood and cognition through neurosteroid pathways, and contributes to bone density and skin thickness.
DHEA production peaks in the mid-20s and declines roughly 1-2% per year after that. By age 70, circulating DHEA-S is typically about 15-20% of its peak. This is the biological backdrop for why DHEA replacement enters the conversation at all in mid-life.
Why dose matters more here than almost anywhere else
DHEA looks deceptively simple on the label. It is just a number on a capsule. The reason competent clinicians dose it cautiously is that DHEA does not stay as DHEA — it converts. The conversion pathway is highly individual, and the same 25 mg dose in two women can produce wildly different downstream hormone profiles depending on the activity of their 17-beta-HSD, 3-beta-HSD, aromatase, and 5-alpha-reductase enzymes.
In one woman, 25 mg of DHEA may push DHEA-S into the optimal range and produce a modest, useful rise in free testosterone. In another woman with high 5-alpha-reductase activity, the same 25 mg may convert preferentially to dihydrotestosterone and produce hair loss at the scalp, hair growth on the chin, and acne along the jawline within six weeks. In a postmenopausal woman with high aromatase activity in adipose tissue, that same dose may convert to estradiol and produce breast tenderness, bloating, or breakthrough bleeding.
The practical implication: the right starting dose for most women is much lower than the supplement bottles suggest. In my practice, a typical adult female starting dose is 5 to 10 mg, occasionally 15 mg. Many women never need more than that. The 25 mg and 50 mg over-the-counter capsules are dosed for men or for someone the manufacturer is imagining who is not the patient sitting in front of me.
For men, the dosing range is wider — typically 25 to 50 mg as a starting range — but the same principle applies. Conversion to estradiol via aromatase is the variable that bites men, particularly men carrying central adipose tissue, where aromatase activity is high.
What I look for on the labs before recommending DHEA
When I evaluate a patient for adrenal DHEA replacement, the panel I want is broader than DHEA-S in isolation. DHEA-S is the obvious anchor — I am looking for a value below the optimal range for the patient's age and sex, typically below 100 mcg/dL in a mid-life woman or below 200 mcg/dL in a mid-life man, with the caveat that "optimal" is not the same as "lab-normal." Lab reference ranges for DHEA-S extend extraordinarily low because they include 80-year-olds. A 45-year-old at the 5th percentile for her age is technically in the reference range and clinically deficient.
Not sure where to start?
The Start Here pathway walks you through the most common entry points and helps you decide which consultation type is the right fit. Five minutes of self-assessment can save you a wrong-direction conversation.
Alongside DHEA-S, I run total and free testosterone, estradiol, SHBG, the full thyroid panel, fasting insulin, and a salivary or plasma cortisol pattern when the symptom picture suggests HPA-axis dysregulation. The reason for the broader panel: DHEA replacement changes the entire steroid output downstream, and I need to know the starting position of every relevant hormone to anticipate where the conversion is going to land.
I also look at scalp hair, hairline behavior, body hair, acne history, menstrual pattern in premenopausal women, and prior response to any androgenic supplement. A patient who flushed out her hair on a previous DHEA trial does not need a second trial at the same dose — she needs a much lower dose, or a different approach entirely, like direct low-dose testosterone in a delivery method that bypasses the conversion variability.
How I dose, titrate, and monitor
My standard approach in hormone optimization for a DHEA-deficient mid-life woman: start at 5 to 10 mg in the morning, ideally a pharmaceutical-grade pharmacy product rather than over-the-counter. Recheck DHEA-S, total and free testosterone, and estradiol at six to eight weeks. The DHEA-S target I am aiming for is somewhere in the upper half of the age-appropriate reference range — typically 150 to 250 mcg/dL in a healthy mid-life woman. I am simultaneously watching free testosterone to make sure we are not pushing it past the upper third of the female reference range, and watching estradiol for unexpected aromatization.
If the labs confirm we are heading the right direction and the patient feels better — energy, sleep depth, libido, cognitive clarity, mood stability are the most common early markers — we hold the dose and recheck at six months. If DHEA-S has come up but free testosterone is still bottom-quartile, the next move is usually direct testosterone supplementation rather than continuing to push the DHEA dose, because pushing DHEA further at that point typically converts to estradiol rather than to testosterone.
If the patient develops androgenic side effects — scalp hair shedding, jawline acne, increased facial hair, oily skin — we drop the dose by half or stop entirely and reassess. Side effects from DHEA usually reverse within four to eight weeks of discontinuation, but the hair shedding can take longer to fully recover.
For men, the same titration discipline applies but the dose ranges shift up. Starting at 25 mg and rechecking at eight weeks is reasonable in most cases, with attention to estradiol and the testosterone-to-estradiol ratio rather than to androgenic side effects.
When DHEA is not the right tool
DHEA is not appropriate for every patient with low-normal DHEA-S. I redirect patients away from DHEA when the underlying problem is HPA-axis dysregulation rather than simple production decline — DHEA in that setting can mask the upstream issue. I avoid DHEA in patients with hormone-sensitive cancers without oncology coordination. I am cautious in PCOS patients, who already have peripheral androgen excess and rarely benefit from added substrate. I am cautious in women with significant insulin resistance, where the conversion profile tends to favor androgens that worsen the metabolic picture.
When the goal is androgen restoration in a woman and DHEA is not the right path, low-dose transdermal testosterone or Biote pellet therapy often does the job more predictably. The pellet route is particularly useful in patients who have struggled with the variability of oral DHEA conversion. For men, the conversation more often moves toward direct men's testosterone replacement rather than pursuing DHEA optimization in isolation.
What I want you to do before you start DHEA
If you are considering DHEA — or already taking it — the next step is the lab work, not the next bottle. The comprehensive lab work panel I described above gives us the data to actually answer the question. Bring any prior labs, any current supplements with their exact doses, and a list of any symptoms you have noticed since starting or stopping previous hormone trials.
Schedule the consultation at the Columbus location or the Warner Robins location. I will read the panel, walk you through where DHEA fits in your specific physiology, and either start a properly dosed protocol or — just as often — tell you that the better answer is something else entirely. DHEA is a useful tool when it is the right tool. It is not the right tool for everyone, and the harm from a wrong-dose, wrong-patient DHEA protocol is real and avoidable.
