Dehydroepiandrosterone (DHEA) Saliva

Optimal result: 137 – 336 pg/mL

Elevated levels of DHEA may reflect endogenous exposure and supplementation.

Other considerations include Polycystic Ovarian Syndrome (PCOS,) adrenal hyperplasia and adrenal tumors.

General recommendations include overall control of the cortisol response, HPA axis support using nutrition, adaptogens, and behavioral modification.

Lower levels of DHEA are seen with advancing age and have been associated with:

- immune dysregulation

- cardiovascular disease

- arthritis

- osteoporosis

- insomnia 

- declining cognition

- depression

- fatigue

- and decreased libido

General recommendations include overall control of the cortisol response, HPA axis support using nutrition, adaptogens, and behavioral modification.

DHEA levels peak at around age 25, then decline steadily through the following decades. DHEA can be converted downstream in the steroidogenic pathway to create androgens and estrogens. It has antioxidant and anti-inflammatory properties and can be protective against corticosterone’s neurotoxic effects.

The normal DHEA concentration alters significantly with age, gender and time of the day. During the day, DHEA values have the highest level in the morning and decrease over the day to the lowest level during night time. This pattern is somewhat similar to Cortisol. For this reason clear indication about the reference values is of utmost importance.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
