What Is DHEA-S?
DHEA-S (dehydroepiandrosterone sulfate) is the sulfated, stable form of DHEA — the most abundant hormone in the human body. It is produced primarily by the adrenal glands and serves as a precursor to both testosterone and estradiol.
Why DHEA-S Is Clinically Significant
DHEA-S peaks in early adulthood (around age 25–30) and then declines steadily throughout life, falling to approximately 10–20% of peak levels by age 70–80.
- Immune modulation — supports immune function and has anti-inflammatory effects
- Neurological health — acts as a neurosteroid influencing mood, cognition, and stress resilience
- Body composition — associated with better muscle maintenance and less visceral fat
- Bone density — contributes to bone remodeling, particularly in postmenopausal women
- Cardiovascular health — higher DHEA-S associated with lower cardiovascular risk in older adults
Chronic Stress and DHEA-S
Under chronic stress, the body prioritizes cortisol production — and DHEA-S levels tend to fall. A low DHEA-S in the context of high cortisol is a pattern consistent with chronic HPA axis activation.
How to Address Low DHEA-S
- Address underlying chronic stress
- Sleep optimization
- Exercise — moderate-intensity resistance and aerobic exercise
- DHEA supplementation — by prescription in Canada; requires physician oversight
- Rule out adrenal insufficiency
Is DHEA-S Tested in a Standard Physical?
No. Stem Health includes DHEA-S in the hormonal panel of the Core and Horizon Assessments.
