What are normal DHEA-S levels?
Normal DHEA-S levels vary significantly by age and sex, typically ranging from 35-430 μg/dL for adult women and 80-560 μg/dL for adult men. DHEA-S naturally peaks in your 20s-30s and gradually declines with age, making regular testing important for hormonal health monitoring.
Understanding DHEA-S and Its Role in Your Body
Dehydroepiandrosterone sulfate (DHEA-S) is one of the most abundant steroid hormones circulating in your bloodstream. Produced primarily by your adrenal glands, with smaller amounts made by the ovaries and testes, DHEA-S serves as a precursor hormone that your body converts into other important hormones, including testosterone and estrogen.
Unlike many hormones that fluctuate throughout the day, DHEA-S levels remain relatively stable, making it an excellent biomarker for assessing adrenal function and overall hormonal health. This stability also means that you can test DHEA-S at any time of day without worrying about timing affecting your results.
DHEA-S plays crucial roles in maintaining energy levels, supporting immune function, preserving bone density, and influencing mood and cognitive function. It also contributes to muscle mass maintenance, sexual function, and the body's stress response system. Understanding your DHEA-S levels can provide valuable insights into your overall hormonal balance and help identify potential health concerns before they become symptomatic. Regular monitoring through comprehensive hormone testing can help you optimize these levels for better health outcomes.
DHEA-S Reference Ranges by Age Group
| Age Group | Women (μg/dL) | Men (μg/dL) | Key Considerations | |
|---|---|---|---|---|
| 20-29 years | 20-29 years | 65-380 | 280-640 | Peak production years |
| 30-39 years | 30-39 years | 45-270 | 120-520 | Beginning of natural decline |
| 40-49 years | 40-49 years | 32-240 | 95-530 | Noticeable decline from peak |
| 50-59 years | 50-59 years | 26-200 | 70-310 | Significant reduction common |
| 60+ years | 60+ years | 13-130 | 42-290 | Lowest levels, wide variation |
Reference ranges may vary between laboratories. Always compare your results to your lab's specific ranges.
Normal DHEA-S Ranges by Age and Sex
DHEA-S levels vary significantly throughout life, following a predictable pattern of rising through childhood, peaking in early adulthood, and gradually declining with age. Understanding these age-specific ranges is essential for proper interpretation of your test results.
Adult Women's DHEA-S Ranges
For adult women, normal DHEA-S levels typically fall within these ranges:
- Ages 18-19: 145-395 μg/dL
- Ages 20-29: 65-380 μg/dL
- Ages 30-39: 45-270 μg/dL
- Ages 40-49: 32-240 μg/dL
- Ages 50-59: 26-200 μg/dL
- Ages 60-69: 13-130 μg/dL
- Ages 70 and above: 17-90 μg/dL
Adult Men's DHEA-S Ranges
Men generally have higher DHEA-S levels than women, with normal ranges including:
- Ages 18-19: 108-441 μg/dL
- Ages 20-29: 280-640 μg/dL
- Ages 30-39: 120-520 μg/dL
- Ages 40-49: 95-530 μg/dL
- Ages 50-59: 70-310 μg/dL
- Ages 60-69: 42-290 μg/dL
- Ages 70 and above: 28-175 μg/dL
It's important to note that these ranges can vary slightly between laboratories due to different testing methods and reference populations. Always compare your results to the specific reference range provided by your testing laboratory.
Factors That Influence DHEA-S Levels
Several factors beyond age and sex can impact your DHEA-S levels. Understanding these influences can help you and your healthcare provider better interpret your test results and develop appropriate strategies for optimization.
Lifestyle and Environmental Factors
- Chronic stress: Prolonged stress can disrupt adrenal function and alter DHEA-S production
- Sleep quality: Poor sleep patterns may negatively impact hormone production
- Exercise: Regular physical activity can help maintain healthy DHEA-S levels
- Diet: Nutritional deficiencies, particularly in healthy fats and certain vitamins, may affect production
- Body weight: Both obesity and being underweight can influence DHEA-S levels
- Smoking: Tobacco use has been associated with altered DHEA-S levels
Medical Conditions and Medications
Certain health conditions can significantly impact DHEA-S production:
- Adrenal disorders: Conditions like Addison's disease or adrenal hyperplasia directly affect production
- PCOS (Polycystic Ovary Syndrome): Often associated with elevated DHEA-S levels in women
- Chronic illness: Long-term health conditions can suppress DHEA-S production
- Medications: Corticosteroids, birth control pills, and certain other medications can alter levels
- Thyroid disorders: Both hyperthyroidism and hypothyroidism can influence DHEA-S
What High DHEA-S Levels Mean
Elevated DHEA-S levels can indicate various conditions or physiological states. While mildly elevated levels might not cause immediate concern, significantly high levels warrant further investigation.
Common causes of elevated DHEA-S include:
- Polycystic Ovary Syndrome (PCOS): One of the most common causes in women of reproductive age
- Congenital Adrenal Hyperplasia: A genetic condition affecting adrenal hormone production
- Adrenal tumors: Both benign and malignant tumors can increase DHEA-S production
- Cushing's syndrome: Though less common, can sometimes present with elevated DHEA-S
- DHEA supplementation: Taking DHEA supplements will naturally increase blood levels
Symptoms associated with high DHEA-S levels may include acne, excessive hair growth (hirsutism) in women, male-pattern baldness, irregular menstrual periods, and mood changes. However, many people with mildly elevated levels experience no symptoms at all.

What Low DHEA-S Levels Mean
Low DHEA-S levels are often associated with aging, but when levels fall below the expected range for your age, it may indicate underlying health issues that deserve attention.
Potential causes of low DHEA-S include:
- Adrenal insufficiency: Including Addison's disease or secondary adrenal insufficiency
- Hypopituitarism: When the pituitary gland doesn't produce adequate hormones
- Chronic stress or illness: Long-term health challenges can suppress production
- Malnutrition or eating disorders: Severe nutritional deficiencies affect hormone production
- Certain medications: Long-term corticosteroid use can suppress natural DHEA-S production
Symptoms of low DHEA-S may include chronic fatigue, decreased muscle mass, reduced libido, mood changes including depression, dry skin, and decreased bone density. These symptoms often overlap with normal aging, making testing particularly valuable for distinguishing between expected age-related changes and potentially treatable deficiencies.
Testing and Monitoring Your DHEA-S Levels
DHEA-S testing is a simple blood test that doesn't require fasting or special timing, making it convenient to include in routine health screenings. Because DHEA-S levels remain stable throughout the day, you can have your blood drawn at any time, unlike cortisol which requires specific timing.
Regular monitoring of DHEA-S can be particularly valuable for:
- Women with symptoms of PCOS or other hormonal imbalances
- Individuals experiencing unexplained fatigue or mood changes
- People interested in optimizing their hormonal health and aging process
- Those with known adrenal or pituitary conditions
- Anyone taking DHEA supplements to ensure levels remain in a healthy range
For comprehensive hormonal assessment, DHEA-S is often tested alongside other hormones like testosterone, estrogen, cortisol, and thyroid hormones. This broader panel provides a more complete picture of your endocrine health and helps identify patterns that might not be apparent from a single biomarker. If you're experiencing symptoms of hormonal imbalance or want to optimize your health, comprehensive hormone testing can provide the insights you need to take action.

Optimizing Your DHEA-S Levels Naturally
While DHEA supplements are available, there are several natural approaches to support healthy DHEA-S production:
Lifestyle Strategies
- Stress management: Practice meditation, yoga, or other stress-reduction techniques
- Quality sleep: Aim for 7-9 hours of restorative sleep nightly
- Regular exercise: Both resistance training and moderate cardio support hormone health
- Balanced nutrition: Focus on whole foods, healthy fats, and adequate protein
- Maintain healthy weight: Both extremes can negatively impact hormone production
- Limit alcohol: Excessive alcohol consumption can interfere with hormone balance
When to Consider Supplementation
DHEA supplementation should only be considered under medical supervision, as inappropriate use can lead to hormone imbalances and unwanted side effects. Your healthcare provider may recommend supplementation if you have documented low levels and symptoms that haven't responded to lifestyle interventions.
It's crucial to monitor your levels regularly if you're supplementing, as too much DHEA can cause acne, hair loss, mood changes, and other hormonal symptoms. The goal is to restore levels to an age-appropriate range, not to achieve the levels of a 20-year-old if you're 50.
Taking Action for Hormonal Health
Understanding your DHEA-S levels is just one piece of the hormonal health puzzle, but it's an important one. This biomarker provides valuable insights into your adrenal function, aging process, and overall endocrine balance. Whether your levels are high, low, or within the normal range, knowing where you stand empowers you to make informed decisions about your health.
Remember that optimal DHEA-S levels are highly individual and depend on various factors including your age, sex, and overall health status. What matters most is understanding your baseline, monitoring changes over time, and working with healthcare providers who can help you interpret results in the context of your complete health picture.
By combining regular testing with healthy lifestyle choices and appropriate medical guidance when needed, you can support optimal DHEA-S levels throughout your life, contributing to better energy, mood, and overall vitality as you age.
