What biomarkers should I test for Hormone Imbalance?

The primary biomarkers to test for Hormone Imbalance include: Testosterone, DHEA-S, Cortisol, Estradiol, SHBG, Progesterone. A comprehensive hormone panel tested at the right time of day (morning for cortisol and testosterone, specific cycle days for female hormones) provides critical insights into metabolic health, stress resilience, and aging trajectory. Early detection allows for targeted lifestyle and, when necessary, medical interventions.

How can biomarker testing help with Hormone Imbalance?

Most annual physicals do not include hormone testing beyond basic thyroid screening. Yet hormones like testosterone, DHEA-S, cortisol, estradiol, SHBG, and progesterone profoundly affect energy, body composition, mood, sleep, cognitive function, and longevity. By the time symptoms are obvious, imbalances may have been present for years. A comprehensive hormone panel tested at the right time of day (morning for cortisol and testosterone, specific cycle days for female hormones) provides critical insights into metabolic health, stress resilience, and aging trajectory. Early detection allows for targeted lifestyle and, when necessary, medical interventions.

What is Testosterone and how does it relate to Hormone Imbalance?

Testosterone is the primary male sex hormone, though it plays important roles in both sexes. It affects muscle mass, bone density, fat distribution, red blood cell production, mood, libido, and cognitive function. Testosterone levels naturally decline with age (about 1-2% per year after age 30), but lifestyle factors can accelerate this decline significantly. Target range: Men: 500-900 ng/dL; Women: 30-70 ng/dL. If testosterone is low, optimize the fundamentals first: sleep 7-9 hours, lift heavy weights, maintain a healthy body fat percentage (15-20% for men), manage stress, ensure adequate zinc and vitamin D, and minimize alcohol. If lifestyle optimization is insufficient, discuss testosterone replacement therapy with an endocrinologist.

What is DHEA-S and how does it relate to Hormone Imbalance?

Dehydroepiandrosterone sulfate (DHEA-S) is the most abundant circulating steroid hormone, produced primarily by the adrenal glands. It serves as a precursor to both testosterone and estrogen. DHEA-S levels peak in the mid-20s and decline progressively with age. Low DHEA-S is associated with fatigue, poor immune function, reduced muscle mass, and accelerated aging. Target range: Men: 200-400 ug/dL; Women: 150-350 ug/dL (age-adjusted). If DHEA-S is low, support adrenal health through stress management, adequate sleep, and balanced nutrition. DHEA supplementation (25-50 mg for men, 10-25 mg for women) can be considered under medical supervision. Address chronic stress, which depletes adrenal output over time.

What is Cortisol and how does it relate to Hormone Imbalance?

Cortisol is a glucocorticoid hormone produced by the adrenal glands in response to stress and low blood sugar. It follows a natural diurnal rhythm, peaking in the early morning and declining throughout the day. Cortisol regulates blood sugar, immune function, inflammation, blood pressure, and the sleep-wake cycle. Both chronically elevated and depleted cortisol cause significant health problems. Target range: Morning (AM): 10-18 ug/dL. If morning cortisol is elevated, prioritize stress management: meditation, adequate sleep, moderate exercise, social connection, and possibly adaptogenic herbs (ashwagandha, rhodiola). If morning cortisol is low, investigate adrenal insufficiency and focus on rest, gentle exercise, and adrenal support. Address the root cause of chronic stress.

Primary Causes & Action Plans

Testosterone

The primary androgen affecting energy, muscle, and mood

Testosterone is the primary male sex hormone, though it plays important roles in both sexes. It affects muscle mass, bone density, fat distribution, red blood cell production, mood, libido, and cognitive function. Testosterone levels naturally decline with age (about 1-2% per year after age 30), but lifestyle factors can accelerate this decline significantly.

Target Men: 500-900 ng/dL; Women: 30-70 ng/dL

Suggested Action Plan

If testosterone is low, optimize the fundamentals first: sleep 7-9 hours, lift heavy weights, maintain a healthy body fat percentage (15-20% for men), manage stress, ensure adequate zinc and vitamin D, and minimize alcohol. If lifestyle optimization is insufficient, discuss testosterone replacement therapy with an endocrinologist.

DHEA-S

The longevity hormone and adrenal health marker

Dehydroepiandrosterone sulfate (DHEA-S) is the most abundant circulating steroid hormone, produced primarily by the adrenal glands. It serves as a precursor to both testosterone and estrogen. DHEA-S levels peak in the mid-20s and decline progressively with age. Low DHEA-S is associated with fatigue, poor immune function, reduced muscle mass, and accelerated aging.

Target Men: 200-400 ug/dL; Women: 150-350 ug/dL (age-adjusted)

Suggested Action Plan

If DHEA-S is low, support adrenal health through stress management, adequate sleep, and balanced nutrition. DHEA supplementation (25-50 mg for men, 10-25 mg for women) can be considered under medical supervision. Address chronic stress, which depletes adrenal output over time.

Cortisol

The primary stress hormone regulating energy and inflammation

Cortisol is a glucocorticoid hormone produced by the adrenal glands in response to stress and low blood sugar. It follows a natural diurnal rhythm, peaking in the early morning and declining throughout the day. Cortisol regulates blood sugar, immune function, inflammation, blood pressure, and the sleep-wake cycle. Both chronically elevated and depleted cortisol cause significant health problems.

Suggested Action Plan

If morning cortisol is elevated, prioritize stress management: meditation, adequate sleep, moderate exercise, social connection, and possibly adaptogenic herbs (ashwagandha, rhodiola). If morning cortisol is low, investigate adrenal insufficiency and focus on rest, gentle exercise, and adrenal support. Address the root cause of chronic stress.

Estradiol

The primary estrogen affecting bone, brain, and cardiovascular health

Estradiol (E2) is the most potent and prevalent estrogen in the body. In women, it is primarily produced by the ovaries and plays a central role in reproductive health, bone density, cardiovascular protection, brain function, and skin health. In men, estradiol is produced by aromatization of testosterone and is important for bone health and libido, but excess levels can cause problems.

Read detailed analysis

Target Women (premenopausal): varies by cycle phase; Men: 20-40 pg/mL

Suggested Action Plan

For women, interpret estradiol in the context of cycle phase and symptoms. Low estradiol in perimenopause/menopause warrants discussion of hormone replacement therapy. For men, elevated estradiol (often from high body fat and aromatase activity) can be addressed through weight loss and reducing aromatase activity.

SHBG

Sex hormone binding globulin controls free hormone availability

Sex Hormone Binding Globulin (SHBG) is a protein produced by the liver that binds testosterone and estradiol, regulating how much of these hormones is free (bioavailable) to act on tissues. SHBG levels are influenced by insulin, thyroid hormones, liver function, and body composition. Low SHBG (common with insulin resistance) leads to more free testosterone, while high SHBG can cause symptoms of low testosterone despite normal total levels.

Read detailed analysis

Target Men: 20-50 nmol/L; Women: 40-120 nmol/L

Suggested Action Plan

If SHBG is low, investigate insulin resistance (the most common cause). Improving insulin sensitivity through diet, exercise, and weight loss typically raises SHBG. If SHBG is high, check thyroid function and liver health. Calculate free testosterone to determine bioavailable hormone levels.

Progesterone

The calming hormone supporting sleep, mood, and fertility

Progesterone is a steroid hormone produced primarily by the corpus luteum in the ovaries after ovulation, and in smaller amounts by the adrenal glands (in both sexes). It plays critical roles in menstrual cycle regulation, pregnancy maintenance, mood stabilization, sleep quality, bone building, and neuroprotection. Progesterone deficiency is common in perimenopause and contributes to estrogen dominance.

Read detailed analysis

Target Women (luteal phase): 10-25 ng/mL; Men: 0.3-1.2 ng/mL

Suggested Action Plan

For women with low progesterone, investigate anovulatory cycles, luteal phase defects, and perimenopause. Support progesterone naturally through stress reduction (cortisol steals progesterone precursors), adequate vitamin B6, vitamin C, and zinc. Bioidentical progesterone supplementation may be appropriate. For men, progesterone is less commonly tested but plays a role in mood and sleep.
