Understanding hormonal health with DHEA can transform your well-being. Discover important insights in our latest post.

Abstract

In this educational post, I present a comprehensive, first-person journey through modern hormone optimization, insulin resistance, polycystic ovary syndrome (PCOS), sex hormone-binding globulin (SHBG), vitamin D synergy, DHEA physiology, and practical prostate cancer risk assessment with total and percent-free PSA. Drawing on decades of collaborative clinical experience and the latest peer-reviewed research, I explain the physiological underpinnings of symptoms and outcomes and clarify how to operationalize these findings in patient care. I show how elevated SHBG is a health signal rather than a target to suppress, how insulin resistance precedes and amplifies hyperandrogenism, and why gut dysbiosis often sits at the root of PCOS. I outline titrated metformin and GLP-1 protocols, progesterone support for miscarriage risk, and conservative testosterone dosing in PCOS-phenotype patients. I also detail the clinical utility of percent-free PSA and prostate MRI to reduce unnecessary biopsies and safely navigate testosterone therapy in men. Throughout, I integrate chiropractic care, functional medicine principles, and practical lessons from my clinical observations at Health Coach Clinic and through multidisciplinary collaborations with leading experts.

Building The Foundation: Why Hormone Care Must Be Integrative, Systems-Based, and Evidence-Guided

As Dr. Alexander Jimenez, DC, APRN, FNP-BC, CFMP, IFMCP, ATN, CCST, I have spent years consolidating the best of endocrinology, metabolic medicine, functional medicine, and integrative chiropractic care into a unified clinical approach. Early in my journey, I learned that protocols focused solely on pellet placement or simple dosing tables cannot keep pace with the complexity of real patients. Many arrive with “normal” serum levels yet feel profoundly unwell—fatigued, foggy, inflamed, dysregulated. That paradox led me deeper into the interconnected physiology of thyroid function, oxygen delivery (O2), vitamin D receptor biology, SHBG dynamics, gut-immune crosstalk, and insulin signaling.

• Key lesson: Symptoms are often driven by receptor-level biology and intracellular signaling, not just serum concentrations.
• Practical implication: I built a layered framework that calibrates endocrine therapy in relation to gut health, insulin resistance, micronutrient sufficiency, and nervous system regulation—areas where integrative chiropractic care excels by aligning biomechanics, autonomic tone, and stress modulation with metabolic healing.

I have collaborated with colleagues across disciplines and continuously integrated new evidence, publishing and teaching while refining care pathways at Health Coach Clinic. Modern hormone care is not about dominating a single lab value; it’s about harmonizing systems that collectively determine energy, mood, fertility, and resilience.

Vitamin D, Thyroid, O2, and Hormone Receptors: Why “Normal Labs” Can Still Feel Dysfunctional

Many patients show “good” testosterone or estradiol on paper but report no improvement in cognition, libido, or vitality. In practice, I found that vitamin D functions as an essential cofactor for genomic hormone receptor activity. The vitamin D receptor (VDR), a nuclear receptor, modulates gene transcription across endocrine axes and affects androgen receptor sensitivity. Low vitamin D reduces receptor responsiveness, blunting clinical effects despite adequate serum hormones.

• Clinical observation: A long-term patient once felt no benefit from hormone therapy until we corrected her vitamin D deficiency. Within months of consistent vitamin D supplementation, she reported improved clarity, energy, and mood—without changing her sex hormone doses.
• Mechanistic insight: VDR activation influences immune tolerance, neurosteroid signaling, and the transcriptional machinery necessary for androgen, estrogen, and thyroid receptor activity (Bouillon et al., 2019).

Similarly, thyroid optimization (including attention to T3 conversion via deiodinases, which decline with age) affects mitochondrial biogenesis, oxygen utilization, and basal metabolic rate. Adequate O2 delivery—facilitated by cardiovascular fitness and musculoskeletal alignment—furthers mitochondrial ATP generation, which supports steroid hormone signaling within target tissues.

• Integrative chiropractic fit: Postural restoration, breathing mechanics, and autonomic balance through spinal and soft-tissue interventions optimize diaphragm function, rib mechanics, and vagal tone, indirectly improving oxygenation, HRV, and endocrine resilience (Harte et al., 2019; McParland et al., 2022).
• Practical recommendations:

• Aim for vitamin D 25(OH)D levels in the 40–60 ng/mL range for most adults, with individualization based on comorbidities and sun exposure (Holick, 2017).
• Monitor TSH, free T4, free T3; consider reverse T3 and thyroid antibodies when clinically indicated.
• Support respiration mechanics and aerobic capacity; mobilize the thoracic spine and rib cage to improve O2 utilization.

In short, optimizing receptor ecology and cellular energetics often unlocks the benefits patients expect from hormone therapy.

SHBG: A Metabolic Barometer and Why We Rarely Lower It

Sex hormone-binding globulin (SHBG) binds testosterone and estradiol, modulating the bioavailability of free hormones. Clinically, high SHBG can limit free testosterone; low SHBG commonly accompanies metabolic syndrome and insulin resistance. Crucially, the literature now shows low-trending SHBG often precedes rising A1C and predicts metabolic dysfunction (Ding et al., 2009; Lakshman et al., 2010).

• Key takeaways:

• Low SHBG is linked to a higher risk of insulin resistance, type 2 diabetes, cardiovascular disease, and mortality (Ding et al., 2009; Selva et al., 2009).
• High SHBG is generally associated with healthier metabolic profiles; it is not an automatic target to suppress.

Therefore, the strategy is not to lower SHBG but to work around it:

• If SHBG is high:

• Raise total testosterone conservatively and support hepatic production with nutrients that balance estrogen metabolism and promote healthy binding dynamics.
• Use targeted supplements such as shilajit (to support mitochondrial function and steroidogenesis) and DIM (to modulate estrogen metabolism), observing changes in free testosterone and symptom relief (Khan et al., 2016; Zeligs, 1998).

• If SHBG is low:

• Treat the underlying insulin resistance and inflammation with lifestyle and nutrition interventions, GLP-1 receptor agonists, and titrated metformin. Improving insulin sensitivity typically raises SHBG levels naturally (Selva et al., 2009).

• Clinical pearl: Elevated SHBG often accompanies thin phenotypes, certain medications, and exogenous estrogen. When free testosterone is limited, I adjust total testosterone doses and employ nutraceuticals that enhance receptor availability and hepatic estrogen handling, ensuring symptom relief without chasing SHBG downwards.

PCOS Root Cause: Gut Dysbiosis, Insulin Resistance, and Hyperandrogenism

The most common endocrine disorder in women, PCOS, is frequently misclassified as primarily ovarian. Emerging research points to a gut-origin model: dysbiosis drives systemic inflammation, insulin resistance, and altered steroid metabolism. This cascade elevates androgens, lowers SHBG, and disrupts ovulation (Qi et al., 2019; Torres et al., 2018).

• Physiology overview:

• Gut dysbiosis increases lipopolysaccharide (LPS) translocation, activating TLR4 and stimulating hepatic and ovarian steroidogenic enzymes.
• Hyperinsulinemia augments theca-cell androgen production, suppresses SHBG, and raises free testosterone (Pasquali & Gambineri, 2006).
• An altered LH: FSH ratio may be observed, though the literature debates its reliability; clinical context matters.

• Diagnostic framework (Rotterdam criteria):

• Two of three: oligo/anovulation, hyperandrogenism (clinical or biochemical), polycystic ovaries (ESHRE/ASRM, 2004).

• Important nuance:

• Many PCOS patients are not obese. PCOS-like syndromes feature hyperandrogenic symptoms without cystic ovaries. Insulin resistance often precedes androgen excess and cycles.

Practical Management of PCOS

• Address gut dysbiosis:

• Ensure regular bowel movements, anti-inflammatory nutrition, and targeted probiotics.
• Clinical note: In my practice, high-quality multi-strain probiotics such as GL-focused formulations help reduce GI symptoms and improve insulin sensitivity. Pair probiotics with fiber, polyphenols, and elimination of trigger foods to calm gut-immune activation (Hill et al., 2014; Cani, 2018).

• Treat insulin resistance:

• Metformin titrated slowly to 2,000 mg/day (extended-release 1,000 mg BID) reduces hepatic gluconeogenesis, improves insulin signaling, decreases ovarian androgen synthesis, and increases SHBG (Viollet et al., 2012).
• GLP-1 receptor agonists (semaglutide, tirzepatide) improve glycemic control, weight, and ovulatory function by reducing appetite, enhancing glucose-dependent insulin secretion, and suppressing glucagon secretion (Wilding et al., 2021; Jastreboff et al., 2022).
• Titration is crucial to avoid GI distress; receptors desensitize over weeks, allowing dose escalation without intolerable side effects.

• Progesterone support:

• PCOS patients are frequently progesterone-deficient, increasing miscarriage risk. I often use 200 mg micronized progesterone nightly; some require an additional 100 mg daytime dose. Maintain luteal-phase levels >20 ng/mL (Practice Committee of ASRM, 2021).
• Rationale: Progesterone stabilizes the endometrium, modulates immune tolerance, and supports early pregnancy.

• Symptom control:

• Spironolactone 100 mg daily in true PCOS for hirsutism/acne; avoid >50 mg in non-PCOS hair-growth cases due to total androgen blockade and sexual side effects (Layton et al., 2017).
• Topical agents for acne may be useful; oral combined approaches depend on fertility goals and risk tolerance.

• Conservative testosterone dosing in PCOS phenotype:

• These patients often have low SHBG and heightened hair follicle sensitivity. Start low-dose testosterone if indicated, using iterative lab/clinical feedback, to avoid worsening acne/hirsutism.
• In pellet therapy, starting doses near 75–87.5 mg can be appropriate when insulin resistance and hyperandrogenic features co-exist. “Start low, go slow” minimizes adverse androgenic reactions.

• Expected timelines:

• Ovulatory restoration and stable cycles can take up to 2–3 years. Symptom relief for hirsutism and acne often requires 6–12 months of consistent therapy.

• Integrative chiropractic fit:

• Stress biology, circadian rhythm, and autonomic tone shape insulin signaling and ovarian function. Chiropractic care that improves sleep quality, reduces pain, and enhances parasympathetic reactivity complements endocrine and nutrition strategies, improving adherence and outcomes (Bjornebekk et al., 2021).

Insulin Resistance: The Primary Driver of Hyperandrogenism in PCOS

In PCOS, hyperinsulinemia directly stimulates ovarian steroidogenesis and reduces SHBG, creating excess free testosterone that drives hirsutism, acne, and menstrual disruption (Pasquali & Gambineri, 2006).

• Why metformin and GLP-1s:

• Metformin attenuates hepatic glucose output, improves muscle glucose uptake, and reduces ovarian androgen production, thereby indirectly raising SHBG and lowering free testosterone (Viollet et al., 2012).
• GLP-1 agonists promote weight loss, reduce inflammation, and improve ovulatory function via central appetite suppression and pancreatic islet effects (Wilding et al., 2021).

• Protocol design:

• Begin metformin ER 500 mg nightly; escalate gradually (every 1–2 weeks) to 1,000 mg BID as tolerated.
• Initiate GLP-1s at low doses; titrate to therapeutic range per labeling, monitoring GI tolerance and glycemic response.

• Lifestyle:

• Emphasize intermittent fasting, low-glycemic nutrition, resistance training, sleep optimization, and stress reduction. These modulate insulin and cortisol, synergizing with medications (Mattson et al., 2017).

• Clinical outcomes:

• Lower insulin enhances SHBG, binding excess androgens; acne and hirsutism fade gradually; ovulatory function returns with consistent metabolic control.

Percent-Free PSA: Precision Prostate Risk Assessment and MRI-First Strategy

Men seeking testosterone therapy often raise questions about PSA and prostate cancer risk. PSA alone is specific but not sensitive. The percent-free PSA adds sensitivity, guiding referral decisions and reducing unnecessary biopsies (Catalona et al., 1998).

• Concepts:
  • Velocity of change matters: A jump from 0.9 to 2.9 ng/mL within a year increases risk even if total PSA is below conventional concern thresholds (Loeb et al., 2012).
  • Percent-free PSA:

• <10%: high likelihood of cancer—urology referral or direct prostate MRI.
• 10–25%: intermediate—consider prostatitis evaluation, repeat testing, MRI if indicated.

• 25%: low likelihood—monitor and recheck.

• Practical lab setup:

• Auto-reflex percent-free PSA if total PSA >4.0 ng/mL; laboratories can enable this on request.

• Prostate MRI:

• I increasingly use multiparametric MRI before biopsy. MRI detects suspicious lesions, grades risk, and frequently identifies prostatitis or BPH, preventing unnecessary invasive procedures (Barentsz et al., 2012).
• Patient-friendly: MRI avoids transrectal risks and clarifies the etiology of PSA rise.

• Caveats:

• Finasteride lowers PSA by ~50%; double-measured values for interpretation (Thompson et al., 2005).
• Sexual activity and prostate massage elevate total PSA but do not alter percent-free PSA substantially, aiding differential decisions.

• Testosterone therapy in men with prior prostate cancer:

• Evolving guidelines now allow resumption once PSA normalizes and oncology/urology deems disease controlled, with shared decision-making and monitoring (Khera et al., 2018).

• Integrative chiropractic fit:

• Pelvic floor mechanics, lower back function, and autonomic regulation influence LUTS (lower urinary tract symptoms). Chiropractic and rehabilitative strategies reduce pelvic congestion, improve posture, and support comfortable activity, which is beneficial for men with BPH or prostatitis symptoms.

DHEA: Neurosteroid, Immune Modulator, and Metabolic Ally

For years, DHEA was viewed as a mere precursor to testosterone/estradiol. Modern research identifies DHEA as a potent neurosteroid with its own receptors in the brain and nervous system, modulating mood, cognition, and immune function (Maninger et al., 2009; Baulieu, 1996).

• Physiology:

• Produced by the adrenal cortex, rapidly sulfated to DHEA-S (the lab-tested form).
• Declines markedly with age—greater proportional decline than testosterone—affecting endothelial function, muscle strength, bone health, and psychological well-being (Mora et al., 2006).
• DHEA and cortisol are reciprocally related; high cortisol suppresses DHEA. Restoring DHEA can improve stress resilience, sleep quality, and mood.

• Clinical observation:

• Women with optimized thyroid and sex hormones who still report low mood, libido, and energy often have low DHEA-S. When we correct DHEA-S into the upper-normal range, they commonly report improved affect, motivation, and sexual desire.

• Benefits linked to DHEA:

• Endothelial support, immune modulation (enhanced NK-cell function), anti-inflammatory signaling, bone accrual, skin integrity, improved mood and cognition (Weber et al., 2014; Panjari & Davis, 2010).

• Dosing:
  • I prefer compounded DHEA for accuracy; start low and titrate:

• Women: ~10–20 mg daily; adjust based on symptoms and labs.
• Men: ~25–50 mg daily as needed; titrate carefully to avoid acne/hair changes due to DHT conversion.

• • Monitor for androgenic side effects; consider DIM and lifestyle to optimize metabolism.
• PCOS caveat:

• Some PCOS phenotypes show elevated adrenal androgens (including DHEA-S). In these cases, avoid adding DHEA; treat insulin resistance and gut dysbiosis first.

• Integrative chiropractic fit:

• Stress modulation through spinal care, breathwork coaching, and movement programs improves cortisol-DHEA balance. Autonomic recalibration helps patients tolerate medication titrations and sustain lifestyle changes.

Practical Protocols: Titration, Safety, and Sequencing

To transform evidence into sustainable outcomes, I use clear protocols:

• Metformin:

• Begin ER 500 mg nightly; then 500 mg BID; advance to 1,000 mg BID as tolerated over weeks.
• Rationale: GI adaptation through gradual receptor desensitization reduces side effects while achieving therapeutic insulin resistance reversal.

• GLP-1 agonists (semaglutide, tirzepatide):

• Start at the lowest labeled dose; escalate based on response and tolerability.
• Rationale: Central satiety, reduced caloric intake, improved beta-cell function; synergy with dietary coaching and resistance training.

• Progesterone in PCOS or luteal insufficiency:

• 200 mg night; add 100 mg daytime if indicated; target luteal levels >20 ng/mL.
• Rationale: Prevent miscarriage, normalize cycles, improve sleep, and reduce anxiety.

• Spironolactone in PCOS:

• 100 mg daily for hirsutism/acne; avoid higher doses; monitor potassium, blood pressure.
• Rationale: Androgen receptor blockade reduces follicular miniaturization and sebum; slow effect over 6–12 months.

• Testosterone in PCOS phenotype:

• Conservative dosing; recheck free testosterone, SHBG, symptoms frequently; add nutraceuticals (DIM, shilajit) to support receptor and hepatic metabolism as needed.

• DHEA:

• Replace only when low; adjust sex hormone plan accordingly; monitor DHEA-S every 8–12 weeks initially.

• Vitamin D:

• Replete to 40–60 ng/mL; monitor calcium, PTH in special populations.

• Percent-free PSA:

• Auto-reflex testing above PSA thresholds; consider MRI before biopsy; adjust interpretation when on 5-alpha-reductase inhibitors.

• Integrative chiropractic:
  • Address musculoskeletal drivers of systemic stress:

• Thoracic mobility for respiratory efficiency.
• Pelvic alignment to reduce pelvic floor load and LUTS.
• Vagal-tone practices to lower cortisol and improve insulin signaling.
• Progressive movement programming to enhance mitochondrial capacity.

Clinical Observations: Real-World Outcomes From Health Coach Clinic

In my practice at Health Coach Clinic, patients who “feel nothing” on initial hormone programs often transform after we address vitamin D, thyroid conversion, gut dysbiosis, and insulin resistance. A patient skeptical about vitamin D became a strong advocate after consistent daily intake unlocked the benefits of her hormone therapy. Several PCOS patients regained cycles over one to three years with titrated metformin/GLP-1 therapy, progesterone, and gut support—an especially meaningful case culminated in a healthy pregnancy after years of irregular cycles.

Men with ambiguous PSA elevations benefited from percent-free PSA stratification and MRI-first evaluation, reducing unnecessary biopsies and clarifying when TRT could proceed safely. Across scenarios, we saw how integrative chiropractic care amplified outcomes by lowering pain and stress, improving sleep, and strengthening adherence—critical factors for metabolic and endocrine success.

Why Integrative Chiropractic Care Belongs In Hormone and Metabolic Treatment Plans

Pain, poor posture, and restricted breathing patterns upregulate sympathetic tone, elevating cortisol and insulin resistance. Autonomic imbalance blunts thyroid conversion, impairs sleep, and worsens mood—undermining endocrine therapies. By improving spinal biomechanics, rib mobility, and diaphragmatic function, integrative chiropractic care reduces systemic stress and supports:

• Enhanced HRV and parasympathetic recovery
• Better oxygenation and mitochondrial output
• Lower pain and improved exercise adherence
• More stable glucose-insulin dynamics

This neuromechanical support is not ancillary—it is a core accelerator for hormone and metabolic programs, aligning the body’s structural, nervous, and endocrine systems for durable change.

Key Action Steps For Clinicians and Patients

• Test comprehensively:

• Thyroid panel (TSH, free T4, free T3), vitamin D 25(OH)D, insulin/glucose/A1C, SHBG, total and free testosterone, estradiol, DHEA-S.
• In men with PSA concerns: percent-free PSA and consider MRI-first.

• Treat root causes:

• Gut dysbiosis with diet, probiotics, and lifestyle.
• Insulin resistance with metformin (titrated) and GLP-1s, plus exercise and sleep optimization.
• Progesterone deficiency in PCOS/luteal-phase insufficiency.

• Dose conservatively:

• Testosterone in PCOS phenotype; spironolactone at appropriate PCOS doses; DHEA only when low.

• Harness integrative chiropractic care:

• Optimize breathing mechanics, vagal tone, and movement to reduce cortisol and enhance metabolic signaling.

• Monitor and iterate:

• Expect 6–12 months for cosmetic androgen symptom changes and 1–3 years for full cycle restoration in PCOS.
• Re-assess every 8–12 weeks early in therapy, then space as stability improves.
