Back to Natural Health Dr. Robert Selig designs 100% natural therapeutic regimens customized around a patient's specific biochemistry.

Dr. Robert Selig, DC - Functional Medicine Practitioner and hair tissue mineral analysis expert - offers customized care plan packages to address chronic health issues affecting most of the population like mineral deficiency, fatigue, and copper toxicity. Blood tests do not provide enough information to properly address chronic health problems because they do not accurately measure deficiencies and toxicities at the root of all illness which is why we test our patients using serial hair tissue mineral analysis (HTMAs). Our mission is to identify, address, and manage chronic health problems in our patients using

Using HTMA helps us get to the root of chronic health problems in order to properly identify needs and address any deficiencies or toxicities. HTMA has been discovered to be the only test available that can accurately measure what is happening inside the cells, not just the blood. To properly address any issues, we give our patients the best nutritional medicine from around the world, and in conjunction, we employ time-tested natural healing methods to improve the efficiency and speed of the recovery process. Our approach has proven to significantly improve wellness, health, and vitality in adult and child patients without the use of expensive drugs and invasive medical procedures. Our goal is to help patients age gracefully and naturally—and avoiding unnecessary dangerous surgeries and future hospital visits. Dr. Selig explains to patients the CRITICAL importance of improving the inner gut terrain, following detoxification protocols, and enhancing the neuro-endocrine function by removing toxic metals in order to see improvement in overall mental, physical, and spiritual well-being. Patients receive invaluable natural health information to follow for the rest of their lives, and our most successful patients learn from Dr. Selig to create new natural healing habits tailored to their own lifestyle.

Xenoestrogens have been categorized into five distinct sources of hormonal disruption that permeate modern life (not including metalloestrogens).

The first category comes directly from the medical system through prescriptions, including birth control pills, hormone replacement therapy, and even tamoxifen which functions as a xenoestrogen.

The second category encompasses the food additives that find their way into nearly everything consumed from processed packages.

The third category includes the cosmetics and personal care products applied to the body daily, from makeup to shampoo to soap.

These first three categories represent areas where individuals have direct control over their exposure, requiring only awareness and conscious choice about what enters the body.

The fourth and fifth categories present a more insidious challenge as they come from environmental sources largely outside individual control.

The fourth category consists of the countless pesticides unleashed upon mankind, covering virtually every square inch of this planet with their toxic presence.

Among these, atrazine stands as the most notorious xenoestrogen, documented to transform male frogs into female frogs in laboratory studies, a finding that extrapolates directly to human health concerns.

When these xenoestrogens enter the developing womb in utero, they can lodge themselves in the brain and disrupt the fundamental architecture of sexual development.

The fifth category comprises industrial chemicals, the entire plastics industry and the plasticizers that leach into food, water, and air from countless sources.

This entire system of hormonal disruption demands our attention and action.

The males in this country have experienced a fifty percent decrease in s***m count over the last fifty years, a statistic that should alarm every one of us.

This decline explains why men are shooting blanks and why fertility clinics now occupy every city across the nation, as conception has become increasingly difficult.

The inability to conceive traces directly to widespread zinc deficiency, driven by toxic metals that systematically displace zinc from its essential positions within the body.

The same toxic metals that steal zinc are also responsible for robbing s***m of the mineral they need to function and fertilize.

This is why fertility rates have collapsed and why so many couples now require medical intervention to conceive.

The zinc finger is a remarkable protein structure that serves as one of the most fundamental mechanisms in human biology.

It brings together key molecular components, allowing them to fold into the precise three-dimensional configuration required for life to function.

Once properly folded, this structure interfaces directly with DNA, enabling the genetic code to be read and translated into the proteins that build and sustain every system in your body.

This mechanism remains the overlooked factor in the widespread hormonal dysfunction we see today.

Millions struggle with Hashimoto's, low thyroid function, low testosterone, low DHEA, estrogen dominance, low progesterone, and persistently low vitamin D that refuses to rise regardless of supplementation.

Yet the connection between these conditions and the zinc finger is rarely made.

The zinc finger is required to activate thyroid hormones, steroid hormones, and fat soluble vitamins, complexing with these molecules to allow the essential work of DNA transcription to proceed.

Within the DNA structure, specific binding domains serve as docking stations where the zinc finger and its associated protein complex must attach with precision.

This attachment is where the actual work of hormone activation and genetic expression occurs, transforming biological potential into functional reality.

When zinc is deficient, this entire cascade collapses, leaving hormones inactive, vitamins unusable, and the body unable to properly regulate its most essential systems.

High levels of heavy metal ions have been detected in various human tissues, including breast tissue.

Research shows a strong correlation between their accumulation and the subsequent development and progression of disease.

These metals are fundamentally estrogenic in their action, meaning they directly influence and disrupt hormonal function throughout the body.

The specific metals implicated in this process include aluminum, antimony, barium, cadmium, chromium, cobalt, copper, lead, mercury, and nickel.

This finding carries profound significance because serial hair tissue mineral analysis consistently reveals these exact metals showing up in patient samples day after day.

The clinical evidence confirms what the research suggests.

We have been thoroughly inundated with these toxic metals through environmental and industrial exposure.

Understanding their influence on estrogen becomes critical because as estrogen bioaccumulates in response to these metals, it simultaneously drives further copper retention within the tissues.

Copper receives specific attention in this research as one of the metalloestrogens with a particularly severe estrogenic effect on human physiology.

This places copper at the center of the metalloestrogen conversation, not as a minor player but as a primary driver of hormonal disruption.

The presence of these metals in breast tissue offers a tangible explanation for the rising rates of estrogen driven conditions affecting the population.

The obesity epidemic raging through the population finds one of its primary drivers in the accumulation of toxic estrogenic compounds building up within our tissues.

Estrogen in its normal physiological role promotes healthy growth, a function we absolutely require and appreciate for proper development and maintenance.

The problem emerges when estrogens become excessive, and excess estrogens promote abnormal growth throughout the body.

This abnormal growth manifests as the obesity we see everywhere, with fat tissue expanding under the direction of these overactive hormonal signals.

The same excess estrogen driving obesity also links directly to acne, cystic formations, fibroids, and the full spectrum of estrogen-driven cancers.

This is why metalloestrogens demand our immediate attention and awareness as a significant health threat.

These heavy metal ions enter our bodies through environmental contamination originating from the titans of industry who have flooded our world with toxic byproducts.

Current research demonstrates that these toxic metals produce a hyperactivation of estrogen receptors, directly linked to the genesis of large fractions of breast cancers.

Scientists are actively working to decipher the molecular basis of how these metalloestrogens activate estrogen receptors with such destructive efficiency.

The mechanisms involved include molecular mimicry, where metals impersonate natural molecules, ionic mimicry at the cellular level, and most critically, the displacement of zinc from its essential protective positions.

Understanding this cascade of disruption reveals why metalloestrogens represent a fundamental threat to hormonal health and metabolic stability.

Copper stands as the worst offender among the metalloestrogens because while it is an essential nutrient mineral, its intimate relationship with estrogen metabolism throughout female physiology becomes dangerous when copper accumulates to toxic levels.

Throughout the ovulatory phases of a woman's cycle, when estrogen reaches its highest peak, copper simultaneously reaches its highest peak, demonstrating a synchronized dance between the hormone and the metal.

During pregnancy, typically around the second and third trimesters, estrogen levels double and copper levels double in direct parallel, further cementing this inseparable biochemical relationship.

The modern environment now floods our bodies with xenoestrogens, tipping the hormonal scales toward estrogen dominance, and estrogen dominance directly causes copper retention within the tissues, leading to toxic copper accumulation.

This creates a vicious cycle where toxic copper influences estrogen while estrogen causes further copper retention, amplifying the presence and activity of both well beyond normal physiological ranges.

Copper holds the distinction of being the most highly electrical metal in all of human physiology because nothing moves electrons quite like copper, and electron movement is precisely how every chemical reaction occurs in the body.

The intimate relationship between copper and estrogen becomes particularly dangerous when excess toxic copper accumulates and begins moving electrons at the wrong time and on the wrong carbon molecules.

This misplaced electrical activity can add a hydroxyl group to an otherwise normal age-related estrogen molecule, transforming it into a malignant estrogen capable of driving cancer formation.

This mechanism explains why toxic metals, with toxic copper as the worst offender due to its hormonal connection, deserve our focused attention, especially considering that most cancers diagnosed today are estrogen-driven malignancies.

While cadmium, mercury, and lead remain significant concerns, toxic copper's inherent connection to estrogen places it at the center of today's hormone-driven cancer epidemic.
