Dr. Jeffrey Dach MD Bio-Identical Hormones and Natural Thyroid

Dr. Jeffrey Dach MD  Bio-Identical Hormones and Natural Thyroid Jeffrey Dach MD is founder and medical director of TrueMedMD, a clinic in Davie Florida specializing in natural thyroid and bioidentical hormones.

Like many people after years in the daily grind of a heavy work schedule, my health eventually declined, and I acquired medical problems of chronic fatigue, aches and pains, and insomnia. Being a physician myself, with 25 years experience with hospital based medicine, I knew that current medical practice using drugs or surgery could not be expected to help. After trying a number of different doct

ors and clinics, I stumbled on the idea of natural medicine and then began the road back to recovery. As a physician, I found this new body of knowledge fascinating, and I continued to study and attend medical meetings covering this topic of natural medicine. As of December 2005, I started a new medical practice located at:

TrueMedMD
7450 Griffin Road, Suite 190
Davie, Florida 33314
Office telephone : 954-792-4663

Returning to clinical medicine was easy for me since my original training was in clinical medicine, including working as an Emergency Room Doctor in Illinois. Our office practice specializes in bio-identical hormones, natural thyroid and other natural medicine therapies.

https://jeffreydachmd.com/2026/06/calcified-plaque-or-soft-plaque-which-one-to-believe/ Calcified Plaque or Soft Plaque, Which One to Believe? The statin drug paradigm was shaken up when studies made it obvious that statin drugs increase the progression of coronary calcification. In 2015, Dr. Michael Henein comes up with the magical thinking that the increased arterial calcification while on a statin drug somehow indicates “arterial plaque repair”, writing: "Despite a greater CAC [Coronary Artery Calcium Score] increase with high dose and long-term statin therapy, events did not occur more frequently in statin treated patients. This suggests that CAC growth under treatment with statins represents plaque repair rather than continuing plaque expansion." Mainstream cardiology needed to preserve the statin drug paradigm, so they came up with magical thinking which says that increasing coronary calcification on a statin drug is somehow “protective arterial repair” and it is the soft plaque and not the calcified plaque that is important. This magical thinking was shown false by the 2004 study by Dr. Paolo Raggi, and by the more recent 2017 study by Dr. Farangis Lavasani who writes: "In asymptomatic diabetic patients undergoing CTCA, CAC score and calcified plaque burden were the plaque compositional variables most predictive of future MACE. Soft plaque compositional variables did not predict future risk. These findings provide further evidence of the relationship between coronary calcium and cardiovascular risk." Note: CTCA = cat scan coronary angiography. CAC= Coronary Artery Calcification. MACE= Major Adverse Coronary Event.

In diabetics, the calcium score is highly predictive of heart attack risk, but the amount of soft plaque is not.

Mary is a 76 year old retired school teacher who has doing well on her thyroid medication for many years. During her last office visit lab review, her serum cortisol was elevated, 23.5 mcg/dl. This is much higher than the last three lab panels where it was normal, in the 15-16 mcg/dl range. Elevated cortisol suggests increased chronic stress, and Mary admitted she was experiencing more stress in her life. The effects of chronic stress can be devastating to our health, and can be understood by reviewing animal models of chronic stress.

Animal Models of Chronic Stress

Animal models of chronic stress using Cold Water-Immersion Restraint (CWIR) are useful to study the effects of stress. The poor little mouse is immobilized in a plastic tube, and then immersed in cold water for about an hour. See the image below:

This above mouse model of restraint stress induces psychological terror, depression and gastrointestinal injury, similar to humans with high-pressure jobs, trauma, or chronic illness or PTSD (post traumatic stress syndrome).

The Devastating Effects on the Gut: “Leaky Gut”

In 2021, Dr. Zhang reported that stressed mice exhibit severe damage to the gastrointestinal tract, even with acute, single-session exposure. Dr. Zhang found small bowel mucosal damage in the duodenum, jejunum, and ileum. The intestinal villi are dramatically shortened, the villus-to-crypt ratio drops, and goblet cells (which produce protective mucus) decrease. The stressed mice exhibit increased intestinal permeability, also called “Leaky Gut”, with FITC-dextran tracer studies showing more leakage of gut bacteria (LPS) into the blood stream causing low level endotoxemia. (2-3)

Increased Inflammation:

Chronic stress causes disruption and dysbiosis of the gut microbiome, the friendly bacteria in our gut shifts towards aerobic and gram-negative bacteria. Chronic stress causes disruption of the intestinal barier, also called Leaky gut with leakage of gram negative bacteria (LPS) into the blood stream causing endotoxemia. This is highly inflammatory and increases pro-inflammatory cytokines such as TNF-alpha and IL-6. Systemic inflammation and gastric ulceration are commonly seen in animal models. Note: LPS is LipoPolySaccharide, also called endotoxin, the outer membrane of gram negative bacteria which is one of the most toxic substances known to mankind. Circulation of LPS in the blood stream from leaky gut is called endotoxemia. For more on how endotoxemia causes coronary artery disease, see:

Low Level Endotoxemia and Coronary Artery Disease

Stress-related Gastritis and Peptic Ulcer Disease.

In 2020, Dr. Yisireyili studied daily restraint stress for two weeks in mice. The experimental mice developed significant gastric mucosal inflammation, gastric erosions, ulcers, enhanced oxidative stress with markedly increased lipid peroxidation, and elevated 8-OHdG, a market for DNA oxidative damage. This same mechanisms can be seen in human stress-related gastritis and peptic ulcer disease. Note: 8-OHdG is 8-hydroxy-2′-deoxyguanosine. (5)

In 2022, Zhang et al. further showed that IL-6 knockout mice experience significant reduced intestinal damage, underscoring inflammation’s central role. Note: Note: IL-6 is a major inflammatory cytokine. IL-6 knockout mice are genetically modified so they cannot mount an inflammatory reaction, thus preventing stress induced gut barrier dysruption. (2-3)

Human Studies of Chronic Stress

Patients suffering from chronic stress may have irritable Bowel Syndrome (IBS), leaky gut, and flare-ups of inflammatory bowel disease. Interventions to protecting the intestinal barrier disruption are useful here, such as Berberine and Lactoferrin.

In 2015, Dr. Kelly reviewed human studies showing psychological stress increases intestinal permeability (Leaky Gut), alters the gut microbiome, and promotes translocation of bacterial products from the gut to the bloodstream (endotoxemia), driving systemic inflammation and stress-related depression and other neuro-psychiatric disorders via the microbiota-gut-brain axis. See Dr. Maes article on Leaky Gut and Chronic Depression: Depression and Leaky Gut. (11)

In 2017, Dr. Yaribeygi highlighted how chronic stress makes our intestinal barrier more permeable (Leaky Gut), contributing to gastrointestinal and systemic inflammatory effects. (10)

Depression-Like Behaviors and Sleep Disruption

In 2019, Dr. Yasugaki showed that Cold Water-Immersion Restraint Stress (CWIRS) daily for three weeks in mice is a reliable model for depression. Mice develop despair-like behavior, anhedonia (loss of pleasure), and other signs of depression, reversed by antidepressant drugs. Dr. Yasugaki also showed chronic stress disturbs sleep: Non-REM sleep (non-rapid eye movement sleep) increases and time awake decreases over weeks,often correlating with a drop in body weight. This is all indicative of poor quality sleep. In addition, many animal studies show anxiety-like behaviors, reduced exploration activity, and decreased cognitive ability. (1)

jeffreydachmd.com/2026/06/stem-cell-therapy-health-benefits-part-two/ Stem Cell Therapy Health Benefits, Part Two. Joe is a 62 year old stock broker with low testosterone, type 2 diabetes, insulin resistance, and metabolic syndrome. His labs show a fasting glucose of 120, a hemoglobin A1C of 6.9 and elevated insulin levels, and a testosterone level of 321. Joe’s health will improve once his testosterone levels have improved with either topical or injectable testosterone. The elevated blood sugar and HbA1C will improve with dietary modification, elimination of sugars and processed carbohydrates from the diet. Another option for Joe is regenerative therapy with umbilical stem cell infusion. These are stem cells derived from umbilical cord cells, also called allogenic mesenchymal stem cells (UC-MSCs) usually obtained from the Wharton’s Jelly in the umbilical cord. A number of my patients have traveled to stem cell clinics outside the US in Antigua, Panama and Mexico for stem cell infusions for various medical conditions. Afterwards, they report on the benefits. They must travel outside the US because umbilical cord stem cell treatments are not FDA-approved in the United States. Although this type of therapy is not mainstream medicine, I predict this will be incorporated into mainstream medicine in the near future. Clinics in Antigua, Panama and Mexico operate under local regulations and promote the stem cells for anti-inflammatory, immunomodulatory, and regenerative properties. The benefits of stem cell therapy arise from the paracrine effects, the secretome or secreted substances released by the stem cells, rather than the stem cells actually engrafting and replacing damaged tissue. There is also a benefit from mitochondrial transfer from the stem cells to damaged cells via tunneling nanotubules (see image below). That said, the preclinical data is impressive and worth reviewing for anyone considering this approach.

jeffreydachmd.com/2026/06/magnesium-for-prevention-and-treating-of-coronary-artery-disease/ Magnesium For Prevention and Treatment of Coronary Artery Disease. A shocking number of Americans suffer from coronary artery disease. Millions are now taking statin drugs, blood pressure pills, water pills and other medications, yet the epidemic continues. What if the answer lies in a simple, inexpensive mineral that most doctors overlook? Magnesium.

In my office, I see patients every day with coronary artery disease, high blood pressure, and cardiac arrythmias. Many have low magnesium levels on testing the RBC Magnesium. When we correct the magnesium deficiency with diet and supplementation, the results are often dramatic: better energy, fewer symptoms, and improved lab markers. Why does magnesium work so well? It is not one single effect. It works through multiple mechanisms that directly address the root causes of atherosclerosis and coronary artery disease.

Important Point: Magnesium is not a drug. It is a natural mineral cofactor for hundreds of enzymes in the body.

Here are the key reasons magnesium is so effective:

1. Anti-Inflammatory Properties

In 2006, Dr. Stephan J Ott demonstrated that coronary artery plaque is fundamentally a polymicrobial biofilm demonstrated by multiple independent labs using 16s ribosome genetic sequencing of atherosclerotic plaque specimens. The plaque in your arteries is not just a passive buildup of cholesterol. It is an active infectious process driven by the microbes originating in the gut and pharynx causing immune reaction and calcification. Infection is one of the strongest triggers in the human body for an inflammatory reaction, thus causing soft tissue calcification in response to intense inflammation. (1)

Inflammatory Pathways Activated

Low magnesium activates inflammatory pathways such as NF-κB and the NLRP3 inflammasome, raising cytokines like CRP, IL-6, and TNF-α. This promotes plaque formation, endothelial activation, and monocyte recruitment. Magnesium supplementation reliably lowers these inflammatory markers. Multiple randomized controlled trials and meta-analyses confirm this benefit, especially in patients who are deficient.

In 2022, Dr. Nicola Veronese did a meta-analysis of 17 randomized trials and found significant reductions in CRP (C-reactive protein, a non-specific inflammatory marker, and other inflammatory markers with magnesium supplementation. The magnesium calms down the inflammatory and immune-driven progression of atherosclerotic plaque. (2)

2. Metabolism and Mitochondrial Function

Magnesium is the single most important nutrient for our mitochondria, the power plants inside every cell. Magnesium is required for ATP synthesis, the Tricarboxylic Acid (TCA) cycle, and electron transport chain enzymes. Without adequate magnesium, mitochondria cannot produce energy efficiently. This leads to increased oxidative stress, calcium overload, and impaired energy metabolism in heart muscle and vascular cells.

Magnesium deficient mitochondria means more inflammation, and inhibition of the reverse cholesterol transport mechanism. Restoring magnesium improves ATP production and cardiac diastolic function, which is especially helpful in heart failure with preserved ejection fraction.

In 2020, Drs. Man Liu and Samuel Dudley reviewed the many mechanisms of magnesiums benefits and stated that magnesium(Mg) supplementation improves mitochondrial function and cardiac diastolic performance in diabetics, The authors write:

In this review, we discuss the possible mechanisms by which Mg deficiency plays detrimental roles in cardiovascular diseases and review the results of clinical trials of Mg supplementation for heart failure, arrhythmias and other cardiovascular diseases…Mg supplementation has shown significant therapeutic effects in HF [heart failure] and CVD [cardio-vascular disease] …. It has also been shown to improve arrhythmias including torsades de pointes (TdP, polymorphic ventricular tachycardia with marked QT prolongation on the electrocardiogram), atrial fibrillation (AF) , ventricular arrhythmias (VA), and arrhythmias in acute myocardial infarction (MI).

3. Antioxidant Properties

Arterial wall breaks are induced by sheer stress at arterial bifurcations, allowing entrance of poly-microbial infection and oxidized LDL particles which incite inflammation, soft tissue calcification and progression of atherosclerotic plaque. Microbial infection of the arterosclerotic plaque, inflammation and calcification and oxidative stress are the initiating events of atherosclerosis.

Magnesium deficiency increases reactive oxygen species (ROS) from mitochondria and depletes antioxidant defenses such as superoxide dismutase and glutathione. At the cellular level, magnesium stabilizes cell membranes, supports enzymatic antioxidants, and reduces lipid peroxidation. It directly counters oxidative damage to cells.The comprehensive review by Drs. Man Liu and Samuel Dudley details these antioxidant mechanisms and their importance in cardiovascular protection.

4. Nitric Oxide Synthesis and Endothelial Function

The endothelium is the inner lining of your arteries, and this is the weak link in vascular health. Endothelial dysfunction means the arteries become stiff, constricted, and subject to damage. Enter Nitric Oxide, the protector of endothelial function. Magnesium is essential for endothelial nitric oxide synthase (eNOS) activity and nitric oxide (NO) production, which keeps vessels dilated and healthy.

Magnesium deficiency with low magnesium RBC levels will reduce nitric oxide production (NO), increase adhesion molecules, and promote vasoconstriction and thrombosis. Magnesium supplementation improves flow-mediated dilation, the standard clinical test of endothelial function, and exercise tolerance in patients with coronary artery disease.

Shecter Oral Magnesium Improves Endothelial Function

A landmark randomized trial in 2000 by Dr. Michael Shechter in Circulation showed that oral magnesium therapy significantly improved endothelial function in patients with coronary artery disease. This is one of the most cited studies in the field. (4)

5. Reduction in Atherosclerotic Plaque

Clinical Evidence from a 2019 Randomized Trial

Further strong support comes from a well-designed 2019 randomized, double-blind, placebo-controlled trial by Dr. Hamid Reza Talari. In this study, diabetic patients on hemodialysis received a modest dose of only 150 mg of magnesium oxide, one of the cheapest and poorly absorbed forms of magnesium. The effect of magnesium supplementation was studied with ultrasound imaging of the carotid arteries. Despite the conservative dose and lower absorption rate, the results were impressive and wide-ranging:

Vascular Health:

In the 2019 study by Dr. Hamid Reza Talari’s using ultrasound imaging to measure carotid intima thickness, there was significant reduction in mean carotid intima-media thickness (CIMT), meaning less atherosclerotic plaque buildup in the carotid arteries. The carotid arteries are the two large arteries (right and left) in the neck which supply blood flow to the brain.

Glycemic Control and Insulin Sensitivity:

Dr. Talari’s study also showed magnesium decreases fasting insulin, lowers HbA1c, lowers high-sensitivity CRP (hs-CRP), increases total antioxidant capacity (TAC) and lowers cholesterol.

Dr. Talari’s is particularly convincing because it was conducted in a very high-risk population, in diabetic patients with advanced kidney disease, yet still produced meaningful improvements across vascular and metabolic parameters, and inflammatory markers with a simple, inexpensive form of magnesium (magnesium oxide). (5)

https://jeffreydachmd.com/2026/05/arthroscopic-meniscus-surgery-for-torn-meniscus/ Arthroscopic Meniscus Surgery for Torn Meniscus: The Evidence For and Against by Jeffrey Dach MD.
Recently, a 58-year-old post-menopausal woman came to see my in the office. She was doing well on her bioidentical hormone program. However, she was experiencing bilateral knee pain and swelling. She had been active all her life, hiking, gardening, and chasing after grandchildren, but now had trouble with stairs and long walks. Her MRI scans showed bilateral degenerative medial meniscus tears along with small joint effusions. No advanced osteoarthritis yet, but the changes were clear. Her orthopedic surgeon had recommended arthroscopic partial meniscectomy, called “keyhole” surgery to trim out the torn pieces of the meniscus on both knees. After a full discussion of the medical literature, she decided against arthroscopic knee surgery. Instead, she chose regenerative treatment with stem cell injections into both knees. Six months later she reported excellent pain relief, better function, and no more effusions. She was back to her normal activities and thrilled she had avoided the surgical procedure.

Atrazine: The Endocrine Disrupting Pesticide Causes Breast Cancer by Jeffrey Dach MD The Trump administration has just re-authorized the pesticide atrazine for widespread agricultural use. Atrazine is one of the most heavily used herbicides in the United States, and the medical literature leaves no doubt: it is a potent endocrine-disrupting chemical (EDC) linked to breast cancer, other cancers, and infertility.
In my office, I routinely advise women concerned about breast cancer risk to avoid EDC chemical exposures. Pesticides like atrazine act as hormone disruptors, interfering with estrogen, testosterone, and the hypothalamic-pituitary-gonadal axis. The result? Altered cell growth, suppressed immunity, and increased cancer risk. This is not speculation. It is documented in peer-reviewed studies.

Atrazine is a Dangerous Pesticide Highlighted in Theo Colburn's Book, Our Stolen Future.

Podcast with Dr. Louise Newson and Jeffrey Dach MD. I have been a fan of Dr. Louise Newson for a long time, and have learned a great deal from her publications in the medical literature on hormone replacement. She is a prolific writer with a large following on her podcast, located in the U.K. in London. The Newson Clinic is located in Stratford-upon-Avon, specializing in hormone replacement for menopausal women. Dr. Louise Newson has a unique medical background, having trained as a pathologist, and with 25 years experience as a GP (general practitioner). And that is why I was so delighted and honored when she invited me on her podcast to discuss my new book, Bioidentical Hormones 101, second edition (2025). Without further ado, here is the 30 minute podcast. Enjoy!

https://jeffreydachmd.com/2026/04/stem-cell-therapy-what-is-it/ Stem Cell Therapy, What Is it? I am frequently asked about offshore stem cell clinics offering mesenchymal stem cell (MSC) therapies. One of the most prominent is the Stem Cell Institute (SCI) in Panama City, Panama, the Riordan Institute. Founded over 20 years ago, specializing in allogeneic human umbilical cord tissue-derived mesenchymal stem cells, “Golden Cells™.” The clinic operates has performed more than 80,000 procedures. They have an in-house GMP-compliant lab, extensive patient data, and a data-driven approach to cell selection. In this post, I’ll provide an overview of the clinic, treatments, claimed outcomes, and costs. I’ll also compare their Golden Cells™ to other clinic MSCs (mesenchymal stem cells) and review key publications by founder Neil H. Riordan, PA, PhD.

The Riordan Clinic in Panama uses Stem Cells from the Umbilical Cord.
