What is Dehydroepiandrosterone Sulfate (DHEA-S)?
DHEA-S is the sulfated (more stable) form of the adrenal hormone DHEA. It is mostly produced in the adrenal cortex and circulates at much higher concentrations than active DHEA. It serves as a “pool” hormone that can convert into androgens or estrogens in peripheral tissues and also modulates neural function.
Why does it matter for long-term health and wellbeing?
Because DHEA-S links adrenal output with hormonal balance, it provides insight into how your body handles stress, maintains metabolic flexibility, and supports sex hormone reserves. Over years, maintaining a robust (but not excessive) DHEA-S level may help preserve energy, lean mass, mood stability, and hormonal adaptability as you age — especially in the absence of overt disease. Monitoring it helps you catch drift before functional decline becomes entrenched.
What’s an optimal level of DHEA-S?
- Laboratory (reference) range: 3.0 to 10.0 µmol/L
- Suggested optimal range (for Vively’s performance / wellness focus): ~ 4.5 to 8.0 µmol/L (i.e. comfortably within, but not pushing, the upper bound)
These figures are illustrative; optimal values may shift with age, sex, and individual context.
What influences DHEA-S levels?
Key modulators include:
- Chronic psychological or physical stress (increases adrenal demand)
- Age (levels naturally decline over adult life)
- Sleep quality and circadian rhythm disruption
- Nutritional status and metabolic stress
- Intense or unbalanced training without adequate recovery
- Hormonal milieu (feedback loops with androgens, estrogens, cortisol)
What does it mean if DHEA-S is outside the optimal range?
- Below optimal: May indicate that adrenal reserve is being taxed or stress pathways are overlearned, potentially leading to reduced hormonal flexibility, tiredness, difficulty recovering, or suboptimal metabolic performance.
- Above optimal: Suggests adrenal hyperstimulation or a shift toward excess androgenic drive, which may disrupt hormonal balance, increase oxidative load, or strain downstream feedback systems.
In either case, an out-of-range result is not a diagnosis — it’s a signal to adjust lifestyle, stress, recovery, and nutrition protocols.
How can I support healthy DHEA-S levels?
- Prioritise quality sleep and consistent circadian rhythms
- Structure stress (mental, physical) with built-in recovery modalities (e.g. breathing practices, light movement, rest)
- Moderate and periodise exercise to avoid chronic overtraining
- Optimise nutrition (micronutrients, protein balance, good fats) and avoid chronic caloric restriction
- Introduce resilience practices (e.g. meditation, cold exposure, sauna) in a balanced way
- Monitor and mitigate chronic inflammatory load and metabolic stress
