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.

We must understand the critical concept of metastatic calcium, which is calcium that migrates and deposits in tissues where it does not belong.

This misplaced calcium is the root cause of what we term deposition diseases, a category that affects virtually every system.

This includes the formation of gallstones and kidney stones, the plaquing of arteries and veins, the development of cataracts in the eyes, and calcification within the brain.

It is also the primary driver of calcium deposition in the joints, manifesting as arthritis, bunions, and various bone deformities.

When this metastatic calcium builds up, it can disrupt every physiological function, leading to the chronic degenerative conditions that inevitably impact us all.

The central goal of true mineral balancing is to regulate and modulate calcium through an understanding of the entire mineral grid.

This systemic approach ensures calcium remains in solution, performing its vital roles, rather than precipitating out to become the deposition diseases that get us all in the end.

Zinc serves as an essential cofactor for the transcription factors that guide genetic expression, a process critically amplified in a developing child.

A young body undergoes massive cellular growth and differentiation, requiring constant DNA transcription and translation to create the proteins necessary for protein synthesis and proper development.

This foundational role extends to every major system.

Zinc activates the entire white blood cell response, forming the backbone of a competent immune system.

It is the crucial element for creating pancreatic juices and digestive enzymes, enabling nutrient breakdown and absorption.

Furthermore, the very production of stomach acid is dependent on adequate zinc status.

When zinc is deficient, especially at rock-bottom levels, these fundamental processes falter, making zinc deficiency one of the most significant factors in developmental, immune, and digestive health.

Without adequate zinc, the body fundamentally loses its immune competence and its crucial DNA auditing and repair system.

Zinc serves as the essential patrol agent in all bodily fluids, including the cerebrospinal fluid, synovial fluid, menstrual and seminal fluids, digestive juices, saliva, and tears.

Within these fluids, zinc performs two critical functions.

It acts as a natural antiseptic, maintaining a microbial balance in the body's internal waters.

Simultaneously, it provides a lubricating effect that prevents the cytoadherence of pathogens, meaning it stops microorganisms like bacteria and yeast from sticking to cell membranes.

This is why zinc status is so vital for mucosal health, helping to prevent recurrent issues like Candida overgrowth and urinary tract infections, especially during times of physiological opening such as the cervical phase of a woman's cycle.

Zinc is not merely a nutrient, it is the guardian of your internal terrain.

In a state of copper overload, copper acts as a metabolic blockade.

It blocks the absorption and function of magnesium, zinc, and selenium, while oxidizing vitamin B6.

This depletion of crucial nutrient minerals prevents the progesterone cycle from initiating, locking the body into a low-progesterone, high-estrogen state.

This explains why most women with estrogen dominance are, in essence, experiencing a copper overload.

The relationship between the hormones estrogen and progesterone is fundamental to normal copper metabolism and balance.

When estrogen is high, copper is retained in the body.

This is powerfully demonstrated during pregnancy, where a woman produces more estrogen than she will in the rest of her lifetime.

This estrogen powerhouse, along with sharply increased serum copper and ceruloplasmin, is not a mistake but a necessity.

The copper drives the essential redox chemistry and transcriptional factors that facilitate the anabolic growth of the placenta.

It is paramount for angiogenesis, the formation of entirely new blood vessels to feed the placenta and widen the uterine arteries, ultimately supporting the new life.

For nearly two decades, I have observed a consistent and alarming pattern.

Every child today is born with a foundational mineral imbalance of low zinc and high copper.

This copper dysregulation has an incredible impact on infants and children, as copper is essential for countless physiological processes, most critically for mitochondrial energy production.

Copper serves as the final donator of electrons to molecular oxygen in the mitochondria, splitting oxygen to create water and our universal energy currency, ATP.

When copper is dysregulated and cannot reach the mitochondria, the body is forced into inefficient anaerobic energy production.

In this anaerobic state, pyruvate converts to lactic acid through fermentation instead of entering the efficient Krebs cycle.

This process creates an acidic, low-oxygen internal environment, which sets the perfect table for candida, yeast, mold, parasites, and worms to thrive and survive.

This foundational imbalance explains the epidemic of pediatric health challenges we are witnessing, rooted in cellular energy failure from day one.

Copper stands as the most profoundly dysregulated metal in all of human physiology.

This dysregulation can manifest as a straightforward deficiency, a toxic overload, or a state of bio-unavailability where copper is present but cannot be utilized by the body.

The pressing question we must ask is why copper has become such a critical issue in our time.

On an energetic and even historical level, we have recently transitioned into the Bronze Age, and bronze is comprised of 90% copper.

For the past two millennia, we have lived under the Iron Age, which controlled and subjugated feminine energy, marginalizing its vital force.

Now, as copper assumes its role as the leading element of this new epoch, the feminine energy it represents must find its rightful place in the scales of balance.

This recalibration is not merely biochemical but deeply cultural and spiritual, explaining both the challenge and necessity of addressing copper imbalance today.
