we don’t guess; we test

Data backed insight into your body’s needs.

Your Solid Foundation

  • This test (hair sample!) is one of the very first things we do because it gives us real data — not guesswork — on what’s happening inside your body.

  • Unlike blood tests, which show us what’s happening in a moment like a snapshot, this test reveals what your body has been storing or depleting over the last few months. It’s like reading your body’s long-term journal, rather than a single page.

  • Minerals are often called the spark plugs of the body because nearly every single biochemical reaction in your body depends on them.

Test kits are shipped directly to you. A simple hair sample is all we need. Pop it back in the post + wait for your results. Test kits can be shipped to the UK/the US/the EU. Wondering if we can get a test kit to you? Contact us here.

WHAT is MEASURED?

  • What Minerals Do in the Body

    Minerals are the foundational building blocks your body relies on for nearly every physiological process — from energy production and hormone balance to detoxification, mood, immunity, and metabolic health.

    Our foundational minerals lab test looks at both major minerals and trace minerals, each essential but needed in different amounts.

    Major Minerals

    These are required in larger quantities and play key roles in structural integrity, electrolyte balance, nerve signaling, and energy production.
    We test: calcium, magnesium, phosphorus, potassium, sodium.

    • Calcium (Ca): Supports bone strength, muscle contraction, nerve signaling, and blood clotting. Low levels are common in women and may contribute to fatigue and muscle irritability.

    • Magnesium (Mg): A cofactor for over 300 enzymes, essential for ATP energy production, stress resilience, blood sugar balance, and muscle/nerve function.

    • Sodium (Na): Regulates fluid balance, nerve impulses, and muscle contractions; closely tied to adrenal function.

    • Potassium (K): Helps maintain stable heart rhythm, supports muscle contraction, balances fluids, and influences blood pressure.

    • Phosphorus (P): Key for bone structure and ATP (cellular energy) production; imbalances may indicate protein metabolism issues or toxicity.

    Trace Minerals

    Needed in smaller amounts but profoundly influential. These minerals regulate hormones, enzymes, immune function, detoxification, and metabolism.
    We test: zinc, copper, chromium, selenium, manganese, iron.

    • Copper (Cu): Supports energy production, neurotransmitter balance, antioxidant defenses, and red blood cell formation.

    • Manganese (Mn): Important for bone development, metabolism of amino acids and cholesterol, and blood sugar regulation.

    • Zinc (Zn): Crucial for immune strength, wound healing, enzyme activity, hormonal balance, mood, and DNA/protein synthesis.

    • Chromium (Cr): Helps regulate blood sugar, improves insulin sensitivity, and supports stable energy levels.

    • Selenium (Se): A potent antioxidant that supports thyroid hormone conversion, immune function, and protection from oxidative stress and heavy metals.

    • Iron (Fe): Needed to carry oxygen in the blood and muscles, supports neurotransmitters, collagen, and hormonal health. Low levels cause fatigue; high levels in hair often reflect retention or toxicity.

    Testing Matters

    Even small shifts in minerals can dramatically impact energy, mood, metabolism, stress tolerance, and overall wellbeing.
    Our foundational minerals lab test reveals long-term patterns that blood work often misses, giving you a deeper look into your metabolic and cellular health.

  • Lead, Mercury, Cadmium, Arsenic, and Aluminum.

    When heavy metals accumulate in the body — even in small amounts — they can disrupt mineral balance, interfere with detoxification pathways, stress the nervous system, and impair mitochondrial energy. These toxins are linked to symptoms such as fatigue, brain fog, hormonal imbalances, headaches, mood changes, skin issues, cardiovascular strain, and difficulty focusing or learning.

    Toxic metals can also block the absorption of essential minerals (like calcium, zinc, and magnesium) and directly suppress thyroid, immune, and metabolic function. Rhythm’s lab provides a unique long-term look at heavy metal exposure, allowing us to identify hidden burdens that blood tests often miss.

  • While individual mineral levels matter, their relationships often reveal far more about your metabolic health, stress load, thyroid function, and overall resilience. Mineral ratios act like “communication lines” between different systems of the body — showing how efficiently your cells are producing energy, managing stress, regulating hormones, and detoxifying.

    Imbalanced ratios can point to issues such as carbohydrate intolerance, adrenal exhaustion, inflammation, hidden copper toxicity, slowed thyroid function, tissue breakdown, or even the development of a protective calcium shell (a marker of chronic stress physiology).

    Here are the primary ratios assessed on the foundational minerals lab and what they can tell us:

    ✨ Calcium / Magnesium (Ca/Mg)

    This ratio reflects metabolic balance and blood sugar handling.
    A high Ca/Mg ratio may indicate carbohydrate intolerance, insulin resistance, or increased emotional stress.
    A low ratio often points to magnesium depletion, muscle tension, anxiety, or difficulty relaxing.

    ✨ Calcium / Potassium (Ca/K)

    Often referred to as the “thyroid ratio.”
    This ratio reflects how efficiently thyroid hormones are being used at the cellular level — which can differ dramatically from blood thyroid labs.
    A high Ca/K ratio may signal sluggish thyroid activity or low cellular metabolism;
    a low Ca/K ratio can point to hyperthyroid patterns or high stress output.

    ✨ Sodium / Potassium (Na/K)

    Known as the “stress and vitality ratio,” this is one of the most important markers on an HTMA.
    It reflects adrenal function, inflammation levels, and how well your body is adapting to life stressors.
    A low Na/K ratio is associated with burnout, emotional overwhelm, chronic stress, or immune dysfunction.
    A high ratio may indicate acute stress, inflammation, or an activated sympathetic nervous system (“fight or flight”).

    ✨ Zinc / Copper (Zn/Cu)

    This ratio influences mood, hormones, immune function, and detox pathways.
    A high Zn/Cu ratio may suggest low usable copper, impacting energy and neurotransmitter function.
    A low Zn/Cu ratio can indicate hidden copper toxicity — a common driver behind anxiety, PMS, skin issues, headaches, and estrogen dominance.

    ✨ Calcium / Phosphorus (Ca/P)

    Reflects metabolic rate and sympathetic versus parasympathetic dominance.
    A high ratio often signals a slower metabolic rate or a protective “calcium shell.”
    A low ratio can reflect fast metabolism, high sympathetic drive, irritability, or tissue breakdown.

  • Your oxidation rate reflects how efficiently your body converts food: carbohydrates, proteins, and fats — into usable energy. This process, known as oxidation, takes place inside every cell and directly influences how you feel: your energy levels, mood stability, metabolism, stress resilience, and even your hormonal rhythm.

    By looking at key mineral ratios in the hair, especially Calcium/Potassium (thyroid) and Sodium/Magnesium (adrenal) the Rhythm Foundational Minerals Lab provides a clear picture of your metabolic pace. When oxidation occurs too fast or too slow, energy production becomes compromised, which can lead to fatigue, irritability, anxiety, cravings, weight changes, and mood fluctuations.

    Your oxidation type is shaped by both genetics and lifestyle factors (particularly nutrition), meaning the foods you eat can either support or strain your metabolic efficiency. Understanding your oxidation rate helps tailor your diet and lifestyle so your body can produce energy in a way that feels smooth, stable, and sustainable.

    ✨ Why Oxidation Rate Matters

    When your diet doesn’t match your metabolic pace, your mitochondria — the energy factories in your cells — struggle to keep up. Over time, this mismatch can contribute to:

    • emotional dysregulation
    • overwhelm or burnout
    • chronic fatigue
    • digestive issues
    • difficulty losing (or maintaining) weight
    • hormone imbalances
    • mental health challenges

    Eating in sync with your oxidation type helps restore balance, improve energy, and support your nervous system.

    ✨ The Three Oxidation Types

    Fast Oxidizers

    Fast oxidizers burn fuel quickly and tend to produce energy at a rapid pace. They often feel best with higher protein and fat intake, which burns more slowly and helps stabilize their system. Blood pH can lean slightly acidic, and without the right nutrients, fast oxidizers may experience irritability, anxiety, or quick energy crashes.

    Slow Oxidizers

    Slow oxidizers convert food into energy at a more gradual rate. They typically thrive on higher healthy carbohydrate intake compared to proteins and fats. Because slow oxidation is commonly associated with diminished thyroid and adrenal activity, this group may be more prone to fatigue, sluggishness, low mood, or feeling “stuck.” Their blood pH tends to be more alkaline, and they respond well to plant-forward meals and lean proteins.

    Mixed (Balanced) Oxidizers

    Mixed oxidizers sit between fast and slow and generally do well with a balanced combination of carbohydrates, proteins, and fats.
    They may shift into fast or slow oxidation under stress, so paying attention to these changes through periodic re-testing can be highly supportive. (You get to re-rest this every year in Rhythm!)

  • Beyond the core minerals that shape your energy, hormones, and metabolic rhythm, we also measure a group of lesser-known but highly impactful trace elements. These minerals work quietly behind the scenes to activate enzymes, support detoxification, stabilize mood, regulate digestion, and influence nervous system balance. Even slight changes in these elements can tell us a great deal about hidden stressors, nutrient deficiencies, or metabolic patterns that aren’t obvious on standard lab work.

    Nickel (Ni)

    Most nickel exposure comes from everyday diet sources such as cocoa, chocolate, hydrogenated oils, soy products, and certain processed foods. It can also leach from batteries, lower-cost dental materials, costume jewelry, and nickel-plated items—common triggers for nickel sensitivity or dermatitis. Smoke and cigarette exposure further increase nickel load. Elevated nickel may interfere with enzyme activity and contribute to skin irritation, immune reactivity, or digestive symptoms.

    Cobalt (Co)

    Cobalt is a structural part of vitamin B12 and is essential for healthy red blood cell formation and nervous system support. Stored mainly in the liver, cobalt helps activate numerous enzymes and is excreted through bile.
    High cobalt levels on an this lab can worsen the toxic effects of selenium and reduce iron absorption—and most importantly, elevated cobalt often points to selenium deficiency, making it a key marker for thyroid and antioxidant function.

    Molybdenum (Mo)

    A vital trace mineral involved in detoxifying sulfites, metabolizing amino acids, and supporting liver pathways. Molybdenum deficiency has been associated with gout-like symptoms and poor sulfur tolerance.
    Low levels—especially in people who consume large amounts of meat—may indicate digestive dysfunction, suboptimal enzyme activity, or the need for digestive support.

    Lithium (Li)

    A naturally occurring trace element required for balanced nerve signaling and emotional regulation. Even in micro-amounts, lithium has a calming, stabilizing effect on the nervous system. Low lithium is extremely common and often under-recognized. Deficiency may contribute to mood instability, irritability, anxiety, disrupted sleep, or reduced stress resilience.

  • Electrolytes: Your Body’s Electrical System

    Electrolytes are minerals that carry an electrical charge, helping regulate hydration, nerve signaling, muscle contraction, and stress response.
    The foundational minerals lab test looks closely at calcium, magnesium, sodium, and potassium, which must stay in the proper balance to maintain optimal function.

    Electrolyte Ratios: What They Reveal

    Calcium + Magnesium Ratio

    This ratio reflects how your body is coping with stress — both past and present. It can indicate:

    • emotional or environmental stress load

    • blood sugar instability

    • chronic inflammation

    • tension in the nervous system

    A balanced ratio supports smooth metabolic function and calm, steady energy.

    Sodium + Potassium Ratio

    Often considered one of the most important markers in the lab. It gives insight into:

    • adrenal function

    • cortisol and aldosterone balance

    • your body’s ability to handle stress

    • overall resilience

    A low ratio is commonly associated with burnout or overwhelm, while a high ratio can suggest acute stress or inflammation.

Your energy, sleep, hormones, mood, digestion, & nervous system function — they all rely on having the right mineral balance.

But it’s not just about individual minerals. It’s about their ratios.

When we look at your test results, we analyse how these minerals are working in relationship to each other because that’s what tells us the story.

for example:

  • A low sodium-to-potassium ratio can suggest adrenal burnout or chronic fatigue.

  • A high calcium-to-phosphorus ratio might indicate slow metabolism or thyroid dysfunction.

  • Elevated copper and low zinc? That may point to hidden inflammation, oestrogen dominance, or detox issues.

Your GP might run standard blood work — and it’s useful for what it is. But blood is tightly regulated by the body. If you're deficient in something, your body pulls minerals out of the tissues to keep blood levels ‘stable.’ That means blood tests can look “normal” even when you're functionally depleted.

The Foundational Minerals Test, on the other hand, shows us your stored mineral reserves AKA what’s actually happening at a tissue level, which is often where symptoms begin. It also gives us clues about long-term stress, metabolic trends, heavy metals, and how your body is compensating behind the scenes.

This kind of insight isn’t something most people ever receive through conventional means and once you see your own data, it just clicks.
