Personalized Functional Nutritional Therapy is bio-individual foundational health nutrition.

Functional Nutritional Therapy Integrates Seamlessly with Clinical Care

Nutrition is molecular, a vital piece of the health puzzle — one that enhances clinician treatment plans, reduces provider workload, and improves patient compliance. Our services are customized for your practice and impart a personalized nutrition plan for each patient, our client, beyond a diet of any sort.

Functional Nutritional Therapy meets each person where they are, honing daily habits that influence recovery, performance, and long term health. We ‘go deep’ with our people to set up a daily strategy to make the game plan executable — refined for each person’s particularities with minimalist stress relief to support nervous system care, a productive holistic adjunct to nutritional therapy and provider treatment.

Variety is the spice of life and the essence of a productive personalized nutrition plan. Tamara does not ever recommend a diet of any sort because diets are depriving by nature. Ours is a ‘nutrition by addition’ approach using food as medicine to support the provider’s action plan and replacing the foods that are not productive with more engaging choices.

Root Cause Insights for Unresolved Symptoms

Clinician Insight for ‘labs are normal but the patient is still unwell’

Many people today live with unexplained fatigue, anxiety, burnout, poor sleep, digestive complaints, recurrent infections, hormonal imbalance, and blood sugar dysregulation all symptoms that standard tests often fail to explain.

Trace Elements Hair Tissue Mineral Analysis | HTMA is a powerful integrative wellness tool within the Daisy Fields Company Functional Nutritional Therapy framework. It is also an excellent screening tool for preventive foundation health support.

Image to symbolize clinical integrity for TEI and Daisy Fields Company is an authorized provider for Trace Elements, Inc Hair Tissue Mineral Analysis.

Trace Elements HTMA and Functional Nutritional Therapy are powerful integrative wellness tools for clinical care.

Trace Elements HTMA offers a long‑term, cellular‑level view of mineral balance and toxic element exposure that blood tests may miss. Understanding mineral balance (not just mineral levels) is essential because minerals operate in synergistic and antagonistic relationships that influence metabolic function.

When paired with Functional Nutritional Therapy, these insights help clinicians help patients

• Identify metabolic stress patterns
• Understand nutritional drivers behind chronic, unexplained symptoms
• Personalize dietary and supplement strategies with precision
• Monitor detoxification and nutrient rebalancing over time

Key Clinical Advantages of Trace Elements HTMA with Functional Nutritional Therapy

  • Long‑term mineral and toxic element assessment

    HTMA measures 35 minerals, toxic elements, and heavy metals from a small hair sample, reflecting a stable 3–4 month biochemical picture. Blood tightly regulates levels, making it less reliable for identifying chronic patterns.

  • Metabolic and glandular insights

    Ratios such as sodium‑to‑potassium and calcium‑to‑potassium reflect adrenal and thyroid activity. These patterns help your patients identify “burnout” or “burdened” states and receive targeted nutritional support to restore energy and metabolic balance.

  • Personalized nutritional therapy

    Enables us to recommend ‘food as medicine’ to nourish burdened patterns and health foundations including blood sugar balance and digestion.  This personalized approach supports the individual rather than one-size fits all dietary guidance or educated guessing.

  • Detoxification monitoring

    Retesting allows clinicians to track the mobilization of toxic elements, evaluate nutrient rebalancing, and assess the patient’s response to the therapeutic protocol.

The Trace Elements (TEI) laboratory has performed over 3 million HTMA tests worldwide since 1984, helping people nourish their metabolic health with clinical insights.  They use highly accurate ICP-Mass Spectrometry (NexION® models) to detect mineral levels, and they maintain a strict policy of not washing the hair samples (a standard practice in other labs) to prevent losing water soluble minerals like sodium and potassium.

Here are some common case examples and how HTMA helps health flourish

Fatigue

  • Sodium‑to‑Magnesium Ratio (Adrenal Function):
    A high ratio may indicate acute stress or adrenal overactivity; a low ratio may reflect adrenal exhaustion or chronic fatigue. When adrenal output is compromised, the body struggles to maintain energy and stress resilience.

  • Calcium‑to‑Magnesium Ratio (Blood Sugar Balance):
    Imbalances can contribute to blood sugar instability, energy crashes, and difficulty maintaining stamina.

Hair Loss

  • Calcium‑to‑Potassium Ratio (Thyroid Ratio)
    A high ratio suggests sluggish thyroid activity and a slower metabolic rate—factors that may contribute to thinning hair or slow hair growth.

  • Sodium‑to‑Potassium Ratio (Adrenal Ratio)
    This ratio reflects adrenal stress, which can influence thyroid function and hair growth patterns.

Moodiness

  • Calcium‑to‑Potassium Ratio (Thyroid Function)
    Imbalances may correlate with mood swings, irritability, or low mood.

  • Sodium‑to‑Potassium Ratio (Emotional Balance)
    This ratio is essential for nervous system stability and emotional resilience, influencing symptoms such as anxiety or irritability.

Recurrent Infections

  • Sodium‑to‑Potassium Ratio (Immune Activity)
    A low ratio may indicate suppressed immune function or an overactive immune response.

  • Copper Levels and Copper‑to‑Zinc Ratio (Immune Modulation)
    Imbalances may reflect compromised immune resilience or increased susceptibility to infections.

Heavy Metals & Toxic Burden

  • Lead, Mercury, Aluminum, and Other Toxic Elements:
    These elements can accumulate over time, disrupting enzyme pathways, mitochondrial function, and cellular health—often contributing to fatigue, brain fog, and chronic symptoms.

  • Calcium Levels as a Detox Marker:
    Elevated calcium may indicate the body is attempting to “wall off” toxic metals in bone and tissue. Over time, this can signal a higher toxic burden and the need for detoxification support.

Gastrointestinal & Metabolic Nutrition

Including Support for GLP‑1–Related Nutrient Depletions

Emerging research is highlighting that GLP‑1 receptor agonists, while effective for appetite regulation and metabolic support, may also contribute to nutrient insufficiencies over time. A recent review published in Clinical Obesity and summarized by Biotics Research evaluated nearly half a million adults and found patterns of reduced intake and lower levels of key nutrients — including vitamin D, iron, calcium, and several B vitamins — along with notable losses in lean mass. These findings were summarized by Biotics Research in their review of the Clinical Obesity publication. You can read their summary here, related to appetite suppression, delayed gastric emptying, and shifts in nutrient absorption. While the data are largely observational, the review emphasizes the importance of clinician awareness to help mitigate unintended consequences.

Functional Nutritional Therapy plays a valuable adjunctive role with GLP-1 patients. By guiding nutritional support for digestive function, and nutrient density that bridges lived experience, personalized support helps clients maintain nutrient sufficiency, preserve lean mass, and support gastrointestinal resilience while using GLP‑1 medications or after a course of GLP-1 treatment has completed.

Digestive Function: A North to South Process

The root cause of discomfort isn’t always where symptoms appear.  Our Functional Nutritional Assessment is a time‑honored, doctor designed non-invasive tool that helps identify foundational health where nutritional therapy is most needed to guide a ‘food as medicine’ approach to eating for nourishment and support the body’s natural healing.

This assessment is integrated into the client’s personalized program of Functional Nutritional Therapy, allowing us to track meaningful improvements that align with each person’s wellness goals.

Nutrition Is Molecular

Food is information.  When the body receives the right nutrients to support converting food to energy for repair and growth, it initiates healing processes. Functional Nutritional Therapy works alongside provider protocols because it focuses on ‘Nutrition by Addition’ while honoring compliance with eliminating foods that are individually counterproductive.  This supports the body to heal so that over time foods may be able to be reintroduced which adds more nutritional diversity and dietary freedom.

Applied Insight + Empathetic Mentoring

Functional Nutritional Therapy blends applied, evidence‑informed insight with empathetic 1:1 mentoring. We help your patients understand what they can eat — not just what to avoid. Personalized Nutrition Plans honor physiology, preferences, and provider protocols so individuals can make lasting, satisfying changes that support digestive health and long‑term outcomes.

Virtual Functional Nutritional Therapy Helps Individuals

People tend to think they are eating ‘clean and healthy’ when in reality, their food rotations may be limited in nutritional value and even counterproductive to their wellness goals.  Functional Nutritional Therapy provides clarity which equates to more joy because eating becomes pleasurable from an energetic and sensory perspective. 

Our expertise helps your patients

  • Navigate the modern food system and choose more real, health supportive foods aligned with your protocols and their wellness goals

  • Build sustainable habits that adapt to busy lives without demanding hours in the kitchen

  • Gain practical, accurate know how to answer the question: “What should I eat to feel good?” throughout all of life’s challenges and stresses.

Conditions We Help Clients Nourish Well

Our expertise is rooted in bio‑individual nutrition, solving complex puzzles of nutritional gaps and identifying overabundance of counterproductive foods, allowing us to support a wide range of digestive and metabolic concerns regardless of diagnosis.

Examples of client conditions we have experience guiding without any nutritional protocol being the same as another. We do not suggest ‘diets’.

  • Digestive Health — Celiac, Barrett’s esophagus, IBS, GERD/heartburn, dysphagia, constipation/diarrhea, diverticulitis, gallbladder

  • Food Allergy & Intolerance — Sensitivities, elimination guidance, reintroduction support — always a focus on more of what the person can eat, drink and do for their well-being

  • Blood Sugar Balance — Pre‑diabetes, Type 2 diabetes, hypoglycemia, insulin resistance

  • Inflammatory & Autoimmune Patterns — Psoriasis, eczema, systemic inflammation

We always welcome a conversation to hear from Clinicians about their patient’s nutritional challenges. The intention is to collaborate with a customized approach that supports your practice and patients. Feel free to Call | Message Tamara or Contact Us.
