CHRONICALLY HOLISTIC
What Is Functional Nutritional Therapy?
Understanding HTMA & the Power of Minerals
Your body is constantly communicating with you. Sometimes, we just need to learn how to listen.
Have you ever felt like something was off with your body, but your blood work came back “normal”?
Maybe you’re constantly exhausted, struggling with digestion, experiencing hormonal changes, or feeling like your nervous system is always running on empty.
As a registered nurse and Functional Nutritional Therapy Practitioner (FNTP), I believe nutrition is one important piece of understanding the bigger picture of your health.
Rather than focusing only on symptoms, Functional Nutritional Therapy explores the foundations that help your body function every single day.
And one of the tools I incorporate into my practice is Hair Tissue Mineral Analysis (HTMA).
What Is Functional Nutritional Therapy?
Functional Nutritional Therapy (FNT) is a personalized, food-first approach to wellness that focuses on supporting the body’s foundational nutritional needs.
Instead of assuming everyone needs the same diet, supplements, or lifestyle recommendations, we look at the individual.
Your health history, stress levels, digestion, eating habits, lifestyle, and nutritional status all contribute to your unique needs.
As a Functional Nutritional Therapy Practitioner (FNTP), I work with clients to identify areas where nutritional support may be beneficial.
The Six Foundations of Nutritional Therapy
1. Nutrient-Dense Whole Foods
Providing the body with protein, healthy fats,
carbohydrates, vitamins, and minerals through
real, nourishing foods.
2. Digestion
Supporting the digestive process from north to south,
including chewing, stomach acid, enzymes,
and regular bowel movements.
3. Blood Sugar Regulation
Building balanced meals that support steady energy,
appetite regulation, and metabolic health.
4. Fatty Acid Balance
Including essential fats that contribute to
cell membrane structure, hormone production,
and normal inflammatory processes.
5. Cellular Hydration
Supporting adequate fluid intake and electrolyte
balance for normal cellular function.
6. Mineral Balance
Understanding how essential minerals contribute
to muscle function, nerve signaling, energy
metabolism, and overall health.
These foundations work together. When one area needs attention, it can influence how you feel in other areas.
Why I Focus So Much on Minerals
Minerals are involved in thousands of processes throughout the body.
They help regulate fluid balance, support nerve communication, contribute to energy production, and maintain healthy muscles and bones.
Magnesium: Supports muscle and nerve function, energy metabolism, and normal blood sugar regulation.
Sodium: Plays an important role in fluid balance, nerve impulses, and muscle contraction.
Potassium: Supports normal heart rhythm, nerve signaling, and muscle function.
Calcium: Essential for bones, muscle contraction, and cellular signaling.
Zinc: Supports immune function, tissue repair, and numerous enzymatic processes.
Copper: Contributes to iron metabolism, connective tissue formation, and antioxidant enzyme activity.
Manganese: Supports metabolism and normal antioxidant defenses.
Molybdenum: Acts as a cofactor for enzymes involved in processing certain compounds in the body.
The goal isn’t simply to take more supplements. It’s to understand your nutritional intake, identify possible gaps, and build a sustainable foundation using food first.
A CLOSER LOOK
What Is Hair Tissue Mineral Analysis (HTMA)?
Hair Tissue Mineral Analysis is a laboratory test that measures concentrations of selected minerals and trace elements in a small sample of hair.
Hair incorporates certain elements as it grows, so testing can provide information about mineral and environmental element exposure over the period represented by the sampled hair.
Unlike blood testing, which measures substances circulating in your bloodstream at the time of collection, HTMA evaluates elements incorporated into hair.
Hair mineral concentrations are not the same as blood or tissue nutrient levels. HTMA cannot reliably diagnose nutritional deficiencies, hormone imbalances, adrenal dysfunction, or metabolic conditions on its own.
Results can also be influenced by hair treatments, external contamination, laboratory methods, and individual differences.
For these reasons, I use HTMA as a complementary tool alongside your health history, dietary intake, symptoms, and conventional testing when appropriate.
A LOOK INSIDE YOUR RESULTS
What Does an HTMA Report Look Like?
One of the most common questions I receive is, “What exactly will my hair mineral analysis show?”
Below is an example of a Hair Tissue Mineral Analysis report from Trace Elements, Inc.
Your Mineral Levels
This page displays nutritional minerals, toxic elements, and additional elements measured in the hair sample.
https://traceelements.com/docs/Graph.pdf#page=1&view=FitHWhat About Mineral Ratios?
Some HTMA reports calculate relationships between minerals, including:
Calcium to Potassium (Ca/K)
A comparison of calcium and potassium concentrations in the hair sample.
Sodium to Magnesium (Na/Mg)
A comparison of sodium and magnesium concentrations.
Sodium to Potassium (Na/K)
A comparison of two minerals involved in normal fluid balance and nerve function.
Zinc to Copper (Zn/Cu)
A comparison of two essential trace minerals.
These ratios are sometimes described in HTMA interpretation systems as indicators of thyroid activity, adrenal function, stress, or metabolic patterns.
It’s important to understand that these interpretations have not been adequately validated for diagnosing those conditions.
I consider mineral ratios exploratory information rather than a diagnosis or a reason to prescribe high-dose mineral supplements.
Food First. Always.
One of the biggest misconceptions about functional nutrition is that everyone needs a cabinet full of supplements.
That’s not how I approach wellness.
I want to know what you’re eating, how you’re digesting your meals, whether you’re eating enough, and how your daily routine supports your body.
Sometimes the first step is as simple as eating breakfast, increasing protein, adding mineral-rich foods, or establishing a more consistent meal schedule.
Mineral-Rich Foods I Love
Magnesium: Pumpkin seeds, almonds, spinach, beans, and dark chocolate.
Potassium: Potatoes, avocado, bananas, white beans, and sweet potatoes.
Calcium: Yogurt, sardines with bones, calcium-set tofu, and leafy greens.
Zinc: Beef, oysters, pumpkin seeds, and eggs.
Copper: Cashews, sesame seeds, lentils, mushrooms, and liver.
Manganese: Oats, pecans, brown rice, and legumes.
Molybdenum: Lentils, beans, whole grains, and peas.
How I Combine Nursing & Functional Nutrition
Before becoming a Functional Nutritional Therapy Practitioner, I spent years working as a registered nurse.
My nursing background taught me the importance of understanding physiology, recognizing concerning symptoms, and appreciating the role of conventional medical care.
Why I Became an FNTP
My journey into Functional Nutritional Therapy started long before I became a practitioner.
After years of navigating chronic illness myself, including POTS, autoimmune conditions, and periods of disability, I knew what it felt like to search for answers while feeling disconnected from my own body.
Even after years of working as a registered nurse, I found myself wanting to understand more about the role nutrition, minerals, digestion, and lifestyle play in our overall health.
That’s what led me to become a Functional Nutritional Therapy Practitioner (FNTP).
I wanted to bridge my clinical nursing background with a more individualized, food-first approach to wellness.
Today, through Chronically Holistic, my goal is to help others feel heard, understand their bodies, and find practical ways to support their health— because I know firsthand how overwhelming that journey can be.
