I was eighteen years old when I got married, and for the first time in my life, I had access to something most people take for granted: good health insurance.
Coming from foster care, my childhood health maintenance had been neglected at best. There were subpar dental checkups—I remember one dentist literally rubbing something on my teeth with his bare fingers and sending me on my way. That was professional dental care? Even as a child, I knew something was wrong with that procedure. Or rather, the lack thereof.
My foster mother didn’t know much about oral care. All her teeth were pulled out before age fifty. The best she knew was to tell us to brush our teeth in the morning and at night. The toothpaste she bought didn’t even contain fluoride. There was no sustainable preventive care, no education about what healthy teeth actually required. I learned about proper oral hygiene from watching commercials—that’s how desperate the situation was.
I survived, but my body paid the price for years of medical neglect.
When my new husband told me about his excellent insurance coverage—dental, vision, everything—I felt something shift. Finally, I could get the care I’d been missing. Finally, someone was going to help me fix what years of neglect had broken.
My first dental appointment as a married woman should have been routine. It wasn’t.
The dentist delivered his diagnosis with what felt like clinical certainty: I had over twenty cavities. Twenty. The number shocked me. But something felt wrong. He wasn’t willing to answer my questions or look me in the eye. I couldn’t help but feel that maybe he wasn’t telling me the entire truth.
I went home and told my husband, expecting concern. Instead, he was reassuring: “Don’t worry. We have insurance. Go ahead and get your teeth fixed.”
I believed him. I believed the dentist. I believed that fixing my teeth was the right thing to do.
What I didn’t know was that those fillings—the ones the dentist drilled into my teeth over painful months—contained mercury. And that mercury was about to change the trajectory of my entire life.
Looking back now, I realize how innocent I was. How trusting. I didn’t question the dentist’s diagnosis of twenty cavities or ask why so many needed mercury fillings. I didn’t research what mercury was or whether there were alternatives. I just did what I was told by the experts.
It was the first time I learned a hard lesson about health care: trusting the system isn’t always enough. Sometimes you have to question, research, and take control of your own well-being.
But I wouldn’t learn that lesson until much later—after my body had already paid the price.
The Dental Nightmare
The dentist’s plan was simple: he would drill out all twenty cavities and fill them with mercury amalgam. Over the course of several months, I sat in that chair repeatedly while he worked on my teeth.
Each visit was painful. The drilling, the grinding, the smell of the dental burr. The vibration that seemed to rattle through my entire skull. I’d leave appointments with my mouth sore and numb, swallowing blood and the metallic taste of whatever was being put into my teeth.
But I told myself this was necessary. This was what good health looked like. This was what insurance paid for. This was what the expert said I needed.
Month after month, I returned. Month after month, more mercury fillings went into my mouth.
I didn’t know what mercury was. I didn’t know it was toxic. I didn’t know that what the dentist was placing in my teeth—material so hazardous it requires special disposal as a biohazard—was being sealed permanently into my body.
I just knew I was following the expert’s orders. I was doing what responsible adults do when they finally have access to healthcare.
Looking back, I can see how naive I was. But I can also see how the system made it easy to be naive. Nobody told me what mercury was. Nobody explained the risks. Nobody offered alternatives. The dentist certainly didn’t volunteer that information while he was billing my insurance for each procedure.
I was trusting the system. And the system was failing me.
I just didn’t know it yet.
The Mysterious Symptoms
It started subtly. Then it became impossible to ignore.
Within months of finishing my dental work, my body began to change in ways I couldn’t explain. First, I noticed my heart fluttered constantly—it felt like my heart kept skipping beats. Then, in addition to that, it began to race. I later learned that my heart was beating in the 100s. What the heck?
I was told that’s called tachycardia—when the heart beats faster than normal and acceptable rates. This causes physical fatigue because the heart is working too hard to pump blood throughout the body. But knowing the medical term didn’t stop the terror I felt every time my chest started pounding.
Sleep became impossible. I might get 4-5 hours on a good night—if I was lucky. It felt like I was on caffeine, even though I didn’t drink coffee or take pills that keep you awake. My mind wouldn’t shut off. My body wouldn’t rest.
And then the weight loss. I lost weight rapidly—not through dieting, but through my body simply wasting away. I went from a size 12 to a size 7. My clothes hung off me like I was a skeleton wearing fabric. People asked if I was sick or dieting. Some women were actually jealous of my petite size, not realizing what was underneath those oversized clothes: skin and bones. It was horrifying. I looked like I was dying from cancer. Thankfully, I wasn’t. But it took a while before I actually knew what was wrong with me.
I went to the doctors. I had tests. Blood work. EKGs. They couldn’t find anything definitively wrong. The symptoms were real, but the cause remained a mystery. One doctor suggested it was anxiety. Another said it was stress. Nobody connected the dots.
Nobody asked about my teeth.
Nobody mentioned mercury.
Years passed with these symptoms. Years of feeling sick without being officially sick. Years of not understanding what was happening to my own body. The medical system that had promised to help me with my teeth had no answers for what was happening now.
I was losing my health in real time, and nobody could tell me why.
The Diagnosis
My general doctor ordered blood work and diagnostic tests. After reviewing the results, he delivered his diagnosis: Graves’ Disease.
I asked him how I got this. I honestly don’t remember everything he said, but I know exactly what he didn’t say: he didn’t mention dental work. He didn’t ask about recent procedures. He suggested stress, anxiety, and other lifestyle factors as the cause.
Then he presented my treatment options. We could manage the Graves’ Disease with medication. Or I could undergo radioactive iodine treatment, which would convert my hyperthyroidism into hypothyroidism—a different condition, but one that’s manageable with medication for better long-term control.
I chose the radioactive iodine treatment.
The day of the procedure, I sat in the waiting room. A technician appeared in a protective suit that looked like an astronaut suit, complete with special gloves. She placed a bottle on a special table in front of me—it resembled a Matryoshka doll with multiple layers. When I reached the final stack, there was a large capsule inside. She pinched it carefully with a special tool and dropped it into the palm of my hand. Then she handed me a glass of water and instructed me to swallow it. The whole scene felt surreal. This tiny capsule, handled with such extreme precaution, was about to fundamentally change my thyroid function.
From that moment forward, I was managing hypothyroidism instead of hyperthyroidism. My body had been chemically altered. The symptoms changed. The treatment changed. My entire health picture shifted.
Nobody had connected the dots to my teeth. Nobody had mentioned mercury.
The Awakening
Years passed after my diagnosis and radioactive iodine treatment. But managing hypothyroidism wasn’t the end of my health crisis—it was just the beginning of new ones.
Unexpectedly, I developed severely elevated blood pressure. Out of nowhere, my body was in crisis. As a middle-aged African American woman, I found myself rushed to the emergency room—often enough to create medical debt I could not pay. The doctors immediately assumed I was having a heart attack. Statistics showed that women like me—Black women my age—had high rates of heart disease and died young from cardiac events. The ER team ran a myriad of tests, expecting to find the worst.
They were surprised when I didn’t have heart disease. But they were puzzled by my persistent high blood pressure. No clear cause. No clear explanation. Just another symptom with no answers.
Then one day in the ER, a doctor asked me questions that my general practitioner never had.
He looked at my medical history, listened to my symptoms, and asked about my dental work. Specifically, he asked about mercury fillings.
When I told him about the twenty mercury fillings from my late teens, he didn’t hesitate. He told me directly: the mercury from those fillings likely contributed to your Graves’ Disease and the complications I’d experienced since.
I was stunned. For years, I’d been told my symptoms were caused by stress, anxiety, or just bad luck. For years, I’d accepted that I simply had to manage whatever condition came next. But this doctor—a doctor who actually cared about getting to the root cause—saw the connection immediately.
More importantly, this doctor gave me something invaluable: he gave me permission to question the system. He showed me that one doctor’s answer wasn’t necessarily the complete answer. He demonstrated that sometimes you have to dig deeper, ask harder questions, and look for the root cause instead of just treating symptoms.
That conversation changed everything.
Years later, I learned that the World Health Organization had issued a report in 2009 recommending a global phase-out of dental mercury due to its impact on human health and the environment. By then, I’d already spent decades managing the consequences of mercury exposure—but at least I finally understood why.
That caring doctor’s willingness to dig deeper and tell me the truth taught me the most important lesson of my health journey: if I wanted to be healthy, I couldn’t passively accept diagnoses. I had to become an active participant in understanding my own body.
That realization was the beginning of everything that came next.
The 30-Year Journey
After that ER doctor revealed the mercury connection, I made a decision that would shape the next three decades of my life: I was going to take control of my health, even if it meant going against conventional recommendations.
As a nurse, I understood the power of medications—but I also understood their serious side effects. I knew that for every symptom, there seemed to be another medication, which would cause new side effects, requiring more medications. That cycle wasn’t sustainable for my body, my health, or my wallet.
So I made a choice: the only medication I truly had to take was thyroid replacement. For everything else—the blood pressure issues, the weight management, the energy fluctuations, the inflammation—I was going to find another path.
I turned to supplements.
My doctors wanted to put me on blood pressure medications. I chose supplements instead—specifically, heart-healthy supplements that could help manage my blood pressure naturally. But this wasn’t a reckless decision. I had to learn how to use them correctly. Taking them incorrectly negatively impacted my thyroid medication. So I worked WITH my doctor while doing my own research to learn which supplements worked well with my medication and which did not.
The learning curve was steep. I visited trusted medical websites like the Mayo Clinic and MedlinePlus to research supplements. Sometimes I called my pharmacist, who had access to my medical profile and could answer questions specific to my condition and medications. I tracked my symptoms carefully. I documented what worked and what didn’t. I learned to evaluate supplement claims and understand how different ingredients might interact with my thyroid medication.
And it worked. I haven’t had to call 911 for a blood pressure crisis in over a year because of those supplements. Being knowledgeable saved both my health and my money.
But I wanted to understand more. I wanted formal training in healthcare so I could truly bridge both worlds—conventional medicine and natural health.
Life gave me that opportunity in an unexpected way.
In 2007, during the subprime mortgage crisis, I lost my accounting position. The financial collapse that devastated so many families hit mine too. I had to make a hard pivot: I sold my home and enrolled in nursing school.
It was terrifying. I was a single mother with four children, reinventing my entire career during one of the worst economic downturns in modern history.
But it was also the fulfillment of a dream I’d had since I was a teenager. My foster mother wouldn’t allow me to attend the vocational high school to become a nurse back then. Now, decades later, I finally had the chance.
By 2008, I became a licensed practical nurse.
Nursing gave me three things I desperately needed: a stable income, the flexibility to raise my children as a single mom, and the medical knowledge to understand both conventional treatments and natural health approaches.
My financial status began to improve. My overall health improved as I applied my newfound knowledge. I finally had the tools to manage my thyroid condition, my blood pressure, and my overall wellness in a way that worked for my body AND my budget.
For the next 17 years, I practiced nursing while continuing my supplement research. I saw firsthand in my patients what I’d experienced myself: people managing chronic conditions, overwhelmed by medications, looking for alternatives but not knowing where to start or who to trust.
I could relate to their journey because I’ve been through it myself.
That’s when I realized my unique position: I was someone who understood the medical system from the inside, who’d personally navigated chronic illness, who’d researched supplements extensively for three decades, and who knew how to communicate complex health information in ways people could understand and trust.
I had become the bridge between two worlds that often don’t speak to each other—conventional medicine and natural health.
Why This Matters Now
Today, I help supplement companies communicate the value of their products in ways that are honest, compliant, and effective.
Why supplement companies? Because I’ve been on both sides of the counter.
I’ve been the desperate customer standing in the supplement aisle at 6:45 PM, trying to find something—anything—that might help when conventional medicine fell short.
I’ve been the patient managing chronic conditions with a combination of necessary medications and carefully researched supplements.
I’ve been the nurse seeing patients overwhelmed by medications and looking for alternatives.
And I’ve spent 30 years learning what actually works, what doesn’t, and how to tell the difference.
That experience gave me something unique: I understand what your customers are going through because I’ve been through it myself. I know what makes them trust a brand and what makes them walk away. I know how to communicate health benefits within FDA guidelines because I’ve spent decades navigating those same rules for my own health.
Most importantly, I understand that being informed about your health isn’t just about feeling better—it’s about preserving your financial wellbeing too. When I learned which supplements could help manage my blood pressure, I saved myself from years of additional medications, side effects, and mounting medical bills.
Being knowledgeable saves both your health and your money.
That’s the message I help supplement companies share with their customers: accurate information, delivered with empathy, grounded in both medical knowledge and real-world experience.
If my story taught me anything, it’s that people deserve to understand what’s going into their bodies and why. They deserve transparency about ingredients, honest communication about benefits, and guidance they can trust.
That’s what I bring to supplement companies: the ability to communicate your value in a way that builds trust, drives sales, and keeps customers coming back—not because of marketing tricks, but because your products actually deliver on their promises.
I spent three decades learning these lessons the hard way. Now I help supplement brands share their value the right way.
