Understanding DHEA’s role
DHEA, or dehydroepiandrosterone, is produced by the reticular zone of the adrenal glands and constitutes the obligatory precursor to testosterone and estrogens. It follows the pregnenolone pathway, itself derived from cholesterol, placing dietary fats at the heart of hormonal synthesis. Its role far exceeds the sexual sphere: DHEA supports physical vitality, libido, innate immunity, mood, and bone density. With age, its production drops spectacularly, making it one of the most reliable markers of biological aging. Understanding this hormonal cascade allows you to grasp why prolonged stress, by diverting pregnenolone toward cortisol, simultaneously impoverishes all downstream hormones.
Monitoring markers
Identifies several early clinical signs of DHEA decline: axillary and pubic hair that thins, skin and eyes that dry out, progressive disappearance of sexual body odor, and decreased libido. These signs often precede biological confirmation and deserve to be monitored year after year. In the laboratory, the reference assay is DHEA-S (sulfated form), more stable than free DHEA and therefore more reliable. The cortisol/DHEA ratio is also valuable: a ratio above 5 indicates adrenal imbalance in favor of stress. Free testosterone testing usefully completes the assessment to evaluate the entire androgenic cascade.
Daily prevention
Stress management is the first lever for preserving DHEA, as chronically elevated cortisol is its main destroyer through the pregnenolone theft mechanism. Quality sleep of 7 to 9 hours per night allows the adrenals to regenerate and maintain a favorable cortisol/DHEA balance. Moderate physical exercise, such as walking, yoga, or light weight training, stimulates DHEA production without exhausting the adrenals. Healthy dietary fats are essential, as cholesterol is the initial precursor for the entire hormonal cascade: egg yolks, avocado, olive oil, and organic butter deserve their place on your plate. Finally, social connections and moments of pleasure naturally stimulate DHEA, reminding us that hormonal health is inseparable from quality of life.

Physiopathology of DHEA deficit
The central mechanism of DHEA deficit is pregnenolone theft: when chronic stress maintains high cortisol demand, the body diverts pregnenolone, the common precursor, toward the cortisol pathway at the expense of the DHEA, testosterone, and estrogen pathway. This imbalance explains why prolonged stress simultaneously affects libido, mood, skin, immunity, and body composition. Meanwhile, the reticular zone of the adrenals, responsible for DHEA production, ages faster than other adrenocortical zones, further aggravating the natural age-related decline. The consequence is a vicious cycle: less DHEA means less stress resistance, therefore more cortisol, therefore even less DHEA. The skin dries out from lack of androgen-dependent sebum, abdominal fat accumulates under cortisol effect, and immunity weakens because DHEA is a powerful modulator of innate immune response. Understanding this cascade allows targeting interventions on the cause rather than symptoms.
Health markers versus laboratory markers
Clinical signs, observable without blood tests, come first; biological markers confirm them. Clinically, sparse axillary and pubic hair, dry skin and eyes, absence of sexual body odor, increased noise sensitivity, abdominal weight gain, and in men, erectile dysfunction are all warning signals. In the laboratory, DHEA-S (sulfated form) is the reference assay as it is stable throughout the day, unlike free DHEA; optimal values are in the upper third of normal range, or 200 to 400 micrograms per deciliter in women and 300 to 500 in men. The cortisol/DHEA ratio is a key indicator of adrenal balance: a ratio above 5 confirms pregnenolone theft. Testing for free testosterone and estradiol allows assessing the impact of the deficit on downstream hormones. Ideally, clinical observation and laboratory testing are combined for a complete picture.
Supporting nutrition
Healthy fats are the starting point for the entire hormonal cascade, as cholesterol is the obligatory precursor to pregnenolone, then DHEA: organic egg yolks, avocado, extra virgin olive oil, and raw butter deserve a daily place on your plate. Quality proteins provide the amino acids necessary for enzymatic synthesis and proper adrenal function. Foods rich in zinc, such as oysters, pumpkin seeds, and liver, directly support the conversion of DHEA to testosterone via the 17-beta-hydroxysteroid dehydrogenase enzyme. Vitamin C, abundant in peppers, kiwi, and citrus fruits, is consumed in large quantities by the adrenals, which concentrate it more than any other organ in the body. In parallel, it is essential to limit ultra-processed foods, refined sugars, and excess caffeine, which stimulate cortisol production and worsen pregnenolone theft. An anti-inflammatory diet rich in micronutrients is the essential foundation for any hormonal restoration strategy.
Targeted supplementation
Vitamin C at 1 to 2 grams daily is the first naturopathic approach to support the adrenals, as they concentrate the highest density of vitamin C in the body and use it massively for hormonal synthesis. Pantothenic acid (vitamin B5) directly nourishes the adrenal cortex and improves stress resistance. Magnesium bisglycinate participates in over 300 enzymatic reactions and calms the hypothalamic-pituitary-adrenal axis overactivated by stress. Zinc bisglycinate is essential for converting DHEA to active sex hormones. Vitamin D, between 2000 and, modulates immunity and participates in overall hormonal balance. Finally, pregnenolone can be considered under professional supervision as a direct precursor to restart the hormonal cascade upstream of DHEA. Doses are set with your doctor or your naturopath, all the more so if you already take a medication.
Lifestyle
Stress reduction is the absolute priority in DHEA deficit, as every cortisol spike diverts pregnenolone from the DHEA, testosterone, and estrogen cascade. Daily meditation, even 10 minutes, and heart rate variability training (5 minutes, 3 times daily) are the most validated tools for lowering basal cortisol. Sleep of 7 to 9 hours per night is non-negotiable: the adrenals regenerate during deep sleep and DHEA is primarily secreted at this time. Moderate physical exercise, such as brisk walking, yoga, or light weight training, stimulates DHEA without exhausting the adrenals, but beware of overtraining which has the opposite effect by increasing cortisol. Social connections and moments of joy naturally stimulate DHEA production through neuroendocrine pathways still poorly understood but well documented. Morning natural light exposure synchronizes the hypothalamic-pituitary-adrenal axis and promotes a cortisol circadian rhythm that preserves DHEA.
Herbal medicine and gemmotherapy
Ashwagandha (Withania somnifera) is the first-choice adaptogen in DHEA deficit: by helping to moderate cortisol, it leaves more pregnenolone available for the DHEA pathway. Tribulus terrestris supports androgen production by stimulating the conversion of DHEA to testosterone, making it a valuable ally in cases of decreased libido or muscle tone. Maca (Lepidium meyenii) acts as a hormonal adaptogen by modulating the hypothalamic-pituitary-gonadal axis without directly providing hormones. Ginseng (Panax ginseng) is an ancestral adrenal tonic that improves stress resistance and supports overall adrenocortical hormone production. In gemmotherapy, oak bud (Quercus robur) is the major remedy for the endocrine system, particularly indicated for supporting fatigued adrenals and restarting hormonal production. Blackcurrant bud (Ribes nigrum) specifically stimulates the adrenal cortex and improves adaptive response to stress.
What you can do
When the adrenals run low
At this stage, DHEA deficit goes beyond simple functional imbalance and reflects advanced exhaustion of the adrenal reticular zone. Pregnenolone theft has become massive and chronic: virtually all hormonal precursors are diverted toward cortisol, depriving DHEA, testosterone, and estrogens of their raw material for probably months or even years. The consequences are systemic: collapse of innate immunity with recurrent infections, loss of muscle and bone mass, accelerated skin aging, cognitive disturbances, and treatment-resistant depression. Observes that this degree of deficit often corresponds to biological age significantly higher than chronological age, with increased risk of degenerative diseases. Without intervention, the vicious cycle perpetuates itself because absence of DHEA further reduces stress resistance capacity, amplifying cortisol diversion. Comprehensive and sustained management is now essential to reverse this spiral.
Mandatory laboratory workup
DHEA-S (sulfated form) testing is now obligatory and urgent to precisely quantify the deficit and guide management. Optimal values are in the upper third of normal range for your age and sex, but at this score level, it is likely your values are in the lower quarter or even below normal. The cortisol/DHEA ratio must be evaluated: a ratio above 7 or 8 confirms severe pregnenolone theft requiring targeted stress axis intervention. Testing should be completed with free testosterone, estradiol, progesterone, and ideally salivary cortisol at 4 points during the day to map the entire hormonal cascade. A complete thyroid profile (TSH, free T3, free T4, antibodies) is also recommended as hypothyroidism and DHEA deficit frequently coexist and mutually worsen. This workup is the non-negotiable prerequisite before any hormonal supplementation decision.
Hormonal reconstruction diet
In severe deficit, nutrition must become a true therapeutic tool centered on rebuilding the hormonal cascade. Give good fats a clear place at every meal to provide the cholesterol necessary for pregnenolone synthesis: organic egg yolks (2 to 3 daily), raw butter, coconut oil, daily avocado, and fatty fish three times weekly. High-quality animal proteins, at 1.2 to 1.5 grams per kilogram of body weight, provide amino acids essential for adrenal enzymatic synthesis. Dietary zinc should be maximized through regular consumption of oysters, veal liver, pumpkin seeds, and pasture-raised red meat. All ultra-processed foods, refined sugars, alcohol, and excess caffeine must be eliminated without compromise as they stimulate cortisol production and directly worsen pregnenolone theft. Cruciferous vegetables, rich in DIM (diindolylmethane), support estrogen metabolism and participate in overall hormonal balance.
What you can add
Vitamin C should be increased to 2 to 3 grams daily in divided doses to saturate the adrenals, which are the most concentrated vitamin C organ in the body and use it massively during stress periods. Pantothenic acid (vitamin B5) is the most specific nutrient for the adrenal cortex and accelerates functional regeneration of the glands. Magnesium bisglycinate must be increased to to calm the stress axis hyperactivation and restore intracellular reserves often profoundly depleted. Zinc bisglycinate (copper to maintain balance) is essential for converting DHEA to testosterone. Pregnenolone, under strict professional supervision, can restart the hormonal cascade upstream by directly providing the DHEA precursor. DHEA supplementation itself, as 7-keto-DHEA or micronized DHEA, can be considered under medical control with regular laboratory monitoring of DHEA-S and downstream hormones. Doses are set with your doctor or your naturopath, all the more so if you already take a medication.
Complete lifestyle overhaul
At this deficit level, stress management is no longer optional but urgent therapeutic priority: every chronic stress source must be identified and, to the extent possible, eliminated or radically reduced. Heart rate variability training must be practiced minimum 3 times daily for 5 minutes, and daily meditation practice of at least 20 minutes is strongly recommended to sustainably lower basal cortisol. Sleep must be sanctified: 8 to 9 hours nightly in total darkness, no screens one hour before bed, retiring before 22:30 to respect the nocturnal adrenal regeneration peak. Physical exercise must be exclusively gentle and regenerative, such as nature walking, restorative yoga, or qi gong; any intense training is best set aside while you rebuild, as it raises cortisol and worsens pregnenolone theft. Hot baths, infrared sauna, and massage activate the parasympathetic nervous system and promote adrenal recovery. Psychological support or stress management therapy may be necessary if stress sources are emotional or relational in nature.
The plants and buds that support
Ashwagandha (Withania somnifera) should be used at therapeutic dose, as a standardised extract, for its moderating action on cortisol, which leaves more pregnenolone available for the DHEA pathway. Rhodiola (Rhodiola rosea) complements ashwagandha by improving resistance to physical and mental stress and protecting the adrenals from exhaustion. Tribulus terrestris actively supports DHEA conversion to testosterone, particularly useful given the androgenic collapse at this stage. Ginseng (Panax ginseng) of extract standardized in ginsenosides acts as a powerful adrenal tonic and restores overall adaptive capacity. In gemmotherapy, oak bud (Quercus robur) is the major remedy for deep endocrine exhaustion, while blackcurrant bud (Ribes nigrum) directly stimulates the adrenal cortex and potentiates the action of all other remedies. Professional follow-up by a naturopath or physician trained in hormonology is essential to adjust this protocol over time and consider, if necessary, direct DHEA supplementation. Doses are set with your doctor or your naturopath, all the more so if you already take a medication.

How to read this test
DHEA (dehydroepiandrosterone) is often called the mother of hormones. Produced by the adrenal glands, it serves as a precursor to testosterone and estrogens, making it a pillar of vitality, libido, muscle tone, and stress resistance. DHEA is also one of the most reliable markers of aging: its levels drop 80 to 90% between ages 25 and 75. Chronic stress accelerates this decline through the mechanism of pregnenolone theft, where the body diverts hormonal precursors toward cortisol production at the expense of DHEA. The clinical observation of Dr Thierry Hertoghe, a Belgian endocrinologist, allows detection of deficit signs even before DHEA-sulfate testing confirms it. This questionnaire is directly inspired by his work and his Atlas of Endocrinology for Hormone Therapy.
