What is S-DHEAS?

DHEAS (Dehydroepiandrosterone sulfate) is the most abundant circulating steroid hormone in the body, produced almost entirely by the adrenal glands. Levels peak in your twenties and decline steadily with age. This makes DHEAS a useful marker for assessing adrenal health and how well your body is maintaining its hormonal reserves under the demands of everyday life.
The role of DHEAS in the body
DHEAS acts primarily as a precursor hormone, it provides the raw material that the body converts into androgens like testosterone and estrogens like estradiol in various tissues. Beyond this, it has direct effects of its own: it supports immune function, helps maintain bone mineral density, and acts as a neurosteroid, protecting the brain and helping to stabilise mood. It also functions as a counterbalance to cortisol, buffering some of the breakdown effects that come with prolonged stress.
Why test DHEAS?
Since DHEAS levels decline steadily with age after twenty years of age in a process known as adrenopause, testing it gives you a sense of whether your adrenal glands are keeping up with your lifestyle demands, or whether chronic stress is accelerating that decline faster than expected.
You should be extra attentive to this marker if you:
Are investigating symptoms of PCOS, such as irregular cycles or unwanted hair growth.
Experience persistent low libido, low mood, or a general lack of drive.
Want to assess your adrenal health during a period of chronic stress or burnout.
Are interested in tracking longevity markers and maintaining hormonal vitality as you age.
High DHEAS: what does it mean?
A high result means the adrenal glands are in a state of overproduction. While this can present as high energy, it can also drive hormonal imbalances elsewhere.
Elevated levels may indicate:
Adrenal hyperplasia or overactivity: The adrenal glands are hyper-responsive, often due to significant systemic stress or genetic traits.
PCOS: In women, high DHEAS is a common sign that the adrenal glands are contributing to an androgen-dominant hormonal state.
Supplementation: Using DHEA supplements will directly and rapidly raise these levels in the blood.
Insulin resistance: High levels of insulin can sometimes signal the adrenals to increase DHEAS production.
Low DHEAS: what does it mean?
A low result suggests that adrenal reserve is depleted, which can affect overall resilience, mood, and hormonal output.
Common reasons for low levels include:
Age-related decline: It is normal for DHEAS to drop with age, but levels that are low relative to your age group can suggest the adrenal glands are aging faster than expected.
Chronic stress: When the body is under sustained pressure, cortisol production is prioritized and DHEAS output tends to decline over time.
Weak brain-adrenal signaling: If the pituitary gland is not sending adequate signals to the adrenal glands, due to chronic stress, illness, or injury, DHEAS production will gradually decline alongside other adrenal hormones.
Chronic illness: Long-term inflammation can drain the body's hormonal precursors, leading to lower circulating DHEAS.
Practical steps for DHEAS balance
You can support healthy DHEAS levels by protecting your adrenal glands and managing the lifestyle factors that drain your hormonal reserves.
Prioritize stress management: Cortisol and DHEAS are produced by the same glands and draw on the same raw materials. Reducing chronic stress helps preserve the capacity for DHEAS production alongside cortisol.
Healthy fats: All steroid hormones are made from cholesterol. Don't fear healthy fats like eggs, avocados, and butter.
Engage in resistance training: Lifting weights has been shown to help maintain DHEAS levels and improve how your body uses these hormones.
Optimize vitamin D and zinc: These nutrients are essential cofactors for the enzymes that produce and convert adrenal hormones.

Testing with Elfcare
S-DHEAS is included in Elfcare’s blood test package and in our full body health check. We analyse your DHEAS alongside cortisol and testosterone to give you a complete picture of whether your body is currently in a state of building and repair or breakdown and stress.
Understanding your DHEAS is a key step in proactive health. Elfcare’s tests provide the data you need to act before imbalances affect your daily life.
Summary
DHEAS is a precursor hormone produced by the adrenal glands, providing the raw material for testosterone and estrogen production throughout the body.
High levels can point toward PCOS, overactive adrenal glands, or the use of DHEA supplements.
Low levels relative to your age are a signal of chronic adrenal strain or sustained systemic stress, both of which are worth addressing proactively.
Mastering your DHEAS data allows you to protect your hormonal reserve, ensuring you maintain the strength, mood, and resilience needed for a long and active life.
