Difference Between DHEA and DHEA-S: DHEA (Dehydroepiandrosterone) and DHEA-S (Dehydroepiandrosterone sulfate) are both hormones that are produced by the adrenal glands. They are precursors to hormones such as estrogen and testosterone and play various roles in the body. However, there are some key differences between DHEA and DHEA-S.

What is DHEA(Dehydroepiandrosterone)?
Dehydroepiandrosterone (DHEA) is a steroid hormone produced mainly by the adrenal glands, which are located on top of the kidneys. It is classified as an androgen. DHEA is produced in both males and females but the levels tend to be higher in males.
Key points about DHEA
- Hormone Production: DHEA is produced in the adrenal glands through a series of enzymatic reactions from cholesterol. It is secreted in a diurnal (daily) rhythm with levels typically highest in the morning and gradually declining throughout the day.
- Age-related Decline: DHEA levels peak in the early to mid-20s and gradually decline with age. By the time individuals reach their 70s, DHEA production is significantly reduced.
- Biological Effects: DHEA serves as a precursor for the production of sex hormones, such as estrogen and testosterone. It plays a role in maintaining the balance of these hormones in the body. DHEA also has additional physiological effects, including potential effects on mood, energy, muscle strength, and overall well-being.
- Clinical Applications: DHEA supplementation has been studied for various conditions, including hormone imbalances, aging-related symptoms, and certain disorders. However, the clinical applications of DHEA supplementation are still being researched, and its long-term effects and optimal dosages require further investigation.
- Measurement: DHEA levels can be measured in blood or saliva samples. Typically, free DHEA (unbound to proteins) is measured to assess its availability for conversion into other hormones.
What is DHEA-S(Dehydroepiandrosterone sulfate)?
Dehydroepiandrosterone sulfate (DHEA-S) is a sulfated form of the hormone dehydroepiandrosterone (DHEA). DHEA-S is the most abundant circulating form of DHEA in the bloodstream. Like DHEA, it is produced primarily by the adrenal glands, which are located on top of the kidneys.
Key Points about DHEA-S:
- Production: DHEA-S is synthesized in the adrenal glands, primarily from DHEA. It is released into the bloodstream and circulates throughout the body.
- Sulfation Process: DHEA is converted to DHEA-S through a process called sulfation. Sulfation involves adding a sulfate group to the DHEA molecule, which increases its stability and water solubility.
- Circulating Form: DHEA-S is the major circulating form of DHEA in the bloodstream. It is present in much higher concentrations than free, unconjugated DHEA.
- Diagnostic Marker: DHEA-S levels can be measured in blood tests to assess adrenal gland function and as an indicator of overall DHEA levels in the body. Abnormal levels of DHEA-S may provide insight into certain adrenal disorders or hormonal imbalances.
- Clinical Applications: While DHEA-S is primarily used as a marker of adrenal function, its clinical applications are limited compared to DHEA. DHEA-S supplementation is not commonly recommended or prescribed, as the sulfated form is less biologically active than DHEA.
Conclusion
DHEA and DHEA-S are distinct forms of the same hormone, each with its own characteristics and functions. DHEA serves as a precursor for sex hormones and has broader clinical applications. while DHEA-S acts as a storage form of DHEA in the body. Understanding the differences between these two forms of the hormone is crucial for appropriate diagnosis, treatment, and supplementation. Seeking guidance from healthcare professionals is essential to ensure the safe and effective use of DHEA and DHEA-S in the context of individual health needs.
FAQs on DHEA and DHEA-S
Q1: What are DHEA and DHEA-S?
Answer:
DHEA (dehydroepiandrosterone) is a steroid hormone produced by the adrenal glands. It serves as a precursor for the synthesis of other hormones, including estrogen and testosterone. On the other hand, DHEA-S (dehydroepiandrosterone sulfate) is a sulfated form of DHEA and is the most abundant circulating form of DHEA in the bloodstream.
Q2: How are they produced?
Answer:
Both DHEA and DHEA-S are primarily produced by the adrenal glands. DHEA is synthesized directly in the adrenal glands, while DHEA-S is formed by adding a sulfate group to DHEA through a process called sulfation.
Q3: What is their circulating form?
Answer:
DHEA circulates in the bloodstream as a free form, unbound to proteins. In contrast, DHEA-S is the major circulating form of DHEA and is present in significantly higher concentrations. The sulfation process makes DHEA-S more stable and water-soluble.
Q4: What are their diagnostic uses?
Answer:
DHEA is often measured as free DHEA in blood or saliva to assess adrenal function and hormonal imbalances. It may be used as a marker for certain conditions. DHEA-S on the other hand, is primarily measured in blood tests to evaluate adrenal gland function and overall DHEA levels in the body.
Q5: Are there clinical applications?
Answer:
DHEA supplementation has been studied for various conditions such as hormone imbalances and aging-related symptoms. It may affect mood, energy, muscle strength, and overall well-being. However, the clinical applications of DHEA-S are limited compared to DHEA. DHEA-S is mainly used as an indicator of adrenal function, and DHEA-S supplementation is not commonly recommended.
