DHEA Therapy in Aging Adults in NYC: Restoring a Foundational Hormone

Dehydroepiandrosterone — DHEA — is produced primarily by the adrenal glands and serves as a precursor to both testosterone and estrogen. It is one of the most abundant steroid hormones in the body during young adulthood, peaking in the mid-20s before beginning a slow, steady decline. By age 70, most adults have DHEA levels just 10–20% of what they were at 25.

This decline correlates with a constellation of changes that were once accepted as inevitable aging: reduced libido, declining muscle mass, increased abdominal adiposity, cognitive fog, lower energy, and diminished immune resilience. At Regen Health Physicians NYC, Dr. Ajit Dhaliwal includes DHEA assessment as a standard component of comprehensive hormone panels — particularly for patients pursuing longevity optimization or struggling with symptoms that conventional evaluation has failed to explain.

What DHEA Does in the Body

DHEA and its sulfated form, DHEA-S, exert widespread biological effects:

• Precursor hormones: Converted peripherally to testosterone and estradiol in target tissues (including brain, skin, bone, and fat)
• Immune modulation: Supports innate immunity; low DHEA-S correlates with increased inflammatory markers in aging
• Metabolic effects: Associated with improved insulin sensitivity and reduced visceral fat in clinical studies
• Neurosteroid: DHEA and DHEA-S act directly on GABA and NMDA receptors in the brain, influencing mood, memory consolidation, and stress resilience
• Bone density: DHEA supports bone mineral density, particularly in postmenopausal women

What the Research Shows

The clinical literature on DHEA supplementation is nuanced:

• A landmark study in JAMA (the DHEAS Memory Study) found that DHEA supplementation improved well-being, sexual function, and bone markers in adults over 60
• The Melatonin and DHEA in Ageing (MADAM) trial demonstrated improved quality of life in both men and women receiving DHEA supplementation
• Multiple randomized trials have shown improvements in sexual function, particularly libido and arousal, in women with adrenal insufficiency or hypoadrenalism
• In men, DHEA supplementation at physiologic doses shows modest improvements in lean mass and mood without the significant risks associated with testosterone monotherapy

That said, DHEA is not universally appropriate. It can aromatize to estrogen — which may be undesirable in certain patients — and can convert to testosterone in women at higher doses, potentially causing androgen-related side effects.

How Dr. Dhaliwal Approaches DHEA

Step 1: Comprehensive Lab Assessment

DHEA therapy is never initiated without baseline testing. Dr. Dhaliwal typically orders:

• DHEA-S (serum)
• Free and total testosterone
• Estradiol, SHBG
• Cortisol AM/PM rhythm
• ACTH stimulation if adrenal insufficiency is suspected
• CMP, CBC, lipid panel

Step 2: Clinical Interpretation in Context

Lab values are interpreted alongside symptoms — a DHEA-S at the low-normal range in a symptomatic 50-year-old may still warrant treatment, while a "normal" level in a patient with exogenous testosterone may reflect a different dynamic entirely.

Step 3: Dosing and Monitoring

DHEA is typically initiated at 25–50 mg/day in most adults, with adjustments based on follow-up labs at 6–8 weeks. Lower doses (5–25 mg) are often appropriate for women to avoid androgenic side effects. DHEA-S is the primary monitoring marker; clinical response and downstream hormone levels guide titration.

Dr. Dhaliwal monitors for:

• Androgen excess in women (acne, hirsutism, oily skin)
• Estrogen excess in men (gynecomastia, fluid retention)
• Impact on SHBG and free testosterone

Step 4: Integration With Full Hormone Panel

DHEA is rarely prescribed in isolation. It is integrated into a broader protocol that may include thyroid optimization, testosterone therapy, cortisol rhythm support, and peptide therapy — all calibrated to the individual's biology and goals.

Who Should Consider DHEA Evaluation?

DHEA testing and consultation is appropriate for:

• Adults over 40 experiencing unexplained fatigue, low libido, or cognitive decline
• Post-menopausal women with sexual dysfunction unresponsive to topical estrogen
• Men on testosterone therapy who want to address all adrenal precursors
• Patients with autoimmune or inflammatory conditions (adrenal contribution)
• Anyone pursuing a longevity-focused medicine program
