The Science Behind Your Cellular Nutrition

Cellular nutrient concentrations better reflect functional status than serum levels alone

Cellular nutrient analysis represents a significant advancement in nutritional testing by examining biomarkers within the cellular environment where metabolic processes actually occur. Traditional serum or plasma measurements often reflect only circulating levels, which may not accurately represent cellular utilisation, functional reserves, or metabolic activity.

Dried Blood Spot (DBS) technology enables precise quantification of multiple biomarkers simultaneously. Advanced mass spectrometry identifies molecular markers with exceptional sensitivity. Comprehensive analysis across amino acids, fatty acids, vitamins, and minerals provides integrated nutritional assessment. Your results create a personalised blueprint for targeted nutritional optimisation.

What Are Epigenetics?

Cellular nutrient analysis represents a significant advancement in nutritional testing by examining biomarkers within the cellular environment where metabolic processes actually occur. Traditional serum or plasma measurements often reflect only circulating levels, which may not accurately represent cellular utilisation, functional reserves, or metabolic activity.

Our Nutritional Biomarker Profile employs advanced Dried Blood Spot (DBS) technology coupled with high-resolution mass spectrometry to analyse critical markers across four primary categories.

Key Insight

The epigenome—the complete set of epigenetic modifications in your DNA—plays a crucial role in numerous immune processes.

The Epigenome's Role in Biological Systems

The epigenome plays a crucial role in numerous physiological processes:

  • Amino Acid Metabolism: Assessing protein building blocks essential for tissue repair, enzyme production, and neurotransmitter synthesis
  • Fatty Acid Composition: Examining membrane structure components and inflammatory mediators
  • Vitamin Status: Measuring critical cofactors for hundreds of enzymatic reactions
  • Mineral Balance: Evaluating essential elements required for optimal cellular function

Epigenetics and Immune Vitality Research

This comprehensive approach provides unprecedented insight into your nutritional status at the functional level where it impacts health and performance.

Biological Age Clocks

Epigenetic clocks use methylation patterns to predict biological age with remarkable accuracy, often revealing significant differences from chronological age.

Lifestyle Responsiveness

Studies show epigenetic patterns respond rapidly to lifestyle changes, making them powerful tools for monitoring health interventions.

Disease Prediction

Specific methylation signatures can predict susceptibility to age-related diseases years before symptoms appear.

Comprehensive Epigenetic Analysis

Our Nutritional Biomarker Profile measures 26 critical markers—spanning amino-acid metabolism, fatty-acid balance, vitamin status and mineral reserves—to reveal exactly how well your cells absorb, utilise and protect key nutrients.

Amino Acid Metabolism

Amino acids are the raw material for every protein your body builds. In this category we analyse the most telling compounds—​from BCAAs and glutamine to carnitine—​to show how efficiently you repair tissue, regulate energy and keep metabolic signals firing.

Branched-Chain Amino Acids (Valine, Leucine, Isoleucine)

BCAAs are pivotal to everyday cellular renewal. They deliver readily available nitrogen for protein repair, help smooth post-meal blood-sugar swings, and trigger the signalling cascades that keep your body’s protein-building machinery in balance.

Why it matters: steadier energy levels, better appetite control, and a stronger foundation for long-term metabolic health.

Carnitine

Carnitine acts as your cells’ fat-fuel shuttle. It escorts long-chain fatty acids into the mitochondria—your internal “power plants”—so they can be burned for clean energy, keeps fat-metabolism pathways running smoothly, and provides extra support to heart muscle and cellular recovery when metabolic stress rises.

Why it matters: steadier day-long energy, healthier lipid balance, and less mid-afternoon fatigue.

Arginine & Citrulline

Arginine & Citrulline are natural nitric-oxide precursors, gently widening blood vessels to keep nutrients and oxygen flowing. They also clear ammonia via the urea cycle, bolster immune activity, accelerate tissue repair, and supply raw material for hormone production.

Why it matters: healthier circulation, easier recovery from everyday stresses, and balanced metabolic and immune function.

Glutamine

Glutamine is your gut’s favourite fuel, nourishing intestinal cells so they can maintain a strong barrier against unwanted particles. At the same time it powers frontline immune cells, helps stabilise the body’s acid-base balance, and serves as the raw material for glutathione—your master intracellular antioxidant.

Why it matters: calmer digestion, more resilient immunity, better pH balance, and broader antioxidant protection for everyday cellular health.

Tryptophan & Tyrosine

Tryptophan & Tyrosine provide the raw ingredients for your brain’s messenger molecules—serotonin, dopamine and norepinephrine—guiding mood, focus and the way you handle stress. They also slot into protein- and enzyme-building pathways, and they’re converted into melatonin to keep your sleep–wake cycle on time.

Why it matters: steadier mood, clearer thinking and naturally deeper sleep.

Additional Amino Acids (Taurine, Threonine, Asparagine, Proline)

Additional Amino Acids (Taurine, Threonine, Asparagine & Proline) work behind the scenes as enzyme cofactors, structural building blocks and chemical messengers. They help steer detox pathways, fortify cellular defences, weave collagen for strong skin and connective tissue, and fine-tune neurotransmitter signalling for smooth communication between cells.

Why it matters: stronger joints and skin, more efficient toxin clearance and steadier cellular messaging for whole-body balance.

Fatty-Acid Landscape: How Your Cells Handle Fats

From membrane flexibility to inflammation control, fatty acids set the tone for cellular health. This panel zeroes in on the lipids that matter most:

Omega-3 Index

Omega-3 Index captures the percentage of EPA and DHA housed in your red-blood-cell membranes—a snapshot that mirrors omega-3 status across every tissue. Because it tracks membrane fluidity and systemic inflammation, the Omega-3 Index is one of the most sensitive early indicators of cardiovascular and metabolic health.

Why it matters: stronger heart and brain support, lower baseline inflammation, and more resilient cell membranes for overall vitality.

EPA (Eicosapentaenoic Acid) & DHA (Docosahexaenoic Acid)

EPA & DHA (Eicosapentaenoic Acid + Docosahexaenoic Acid)
These long-chain omega-3s slot into every cell membrane, calming inflammatory cascades, shaping receptor function, and powering healthy blood-flow mechanics. DHA dominates brain tissue, underpinning cognition and mood signalling, while EPA fine-tunes immune balance and triglyceride control—together giving your body its most versatile lipid toolkit.

Why it matters: sharper mental clarity, a calmer inflammatory baseline and multi-layered cardiovascular support.

Linoleic Acid

As the sole essential omega-6 fatty acid, linoleic acid is woven into membrane architecture and converted into eicosanoids—potent signalling molecules that direct local inflammation and metabolic tone. It also helps maintain the skin’s barrier and influences how efficiently cells respond to insulin.

Why it matters: resilient skin, steadier metabolic health and a balanced, not over-active, inflammatory response.

Oleic Acid

Best known from olive and avocado oils, this omega-9 monounsaturated fat keeps membranes fluid, optimises cell-to-cell signalling and gently tempers inflammation. Diets rich in oleic acid correlate with healthier cholesterol profiles and improved vascular function, mirroring the benefits seen in Mediterranean eating patterns.

Why it matters: everyday heart protection, better lipid balance and more flexible cell membranes for whole-body vitality.

Vitamin Intelligence: Micronutrients That Keep Metabolism Running

Vitamins act as molecular keys, unlocking hundreds of enzyme-driven reactions that govern energy, immunity and cellular repair. Your panel tracks the four most telling micronutrients:

Active Vitamin B12 (Holotranscobalamin)

This is the tissue-ready form of B12 that fuels DNA synthesis, red-blood-cell formation and methylation—processes essential for nerve integrity and steady energy production. Because it measures only the usable fraction, holotranscobalamin flags emerging shortfalls sooner than a total-B12 test.

Why it matters: sharper cognition, sustained vitality and early protection against pernicious deficiency.

Vitamin D

Technically a hormone, vitamin D orchestrates calcium balance for bones and teeth, primes innate immunity and helps dial down excessive inflammation. It also influences how cells grow, specialise and renew themselves.
Why it matters: stronger skeletal support, more resilient immune defences and healthier long-term inflammatory tone.

Vitamin A (Retinol)

Retinol safeguards night vision, keeps epithelial tissues and mucous membranes intact, and modulates gene expression via nuclear receptors. Adequate stores are also pivotal for fertility and early embryonic development.

Why it matters: clearer eyesight, tougher skin-and-gut barriers and balanced immune surveillance.

Vitamin E (α-Tocopherol)

As your primary fat-soluble antioxidant, α-tocopherol embeds in cell membranes to intercept free-radical damage. It fine-tunes inflammatory signalling, supports vascular elasticity and helps keep platelets from clumping excessively.

Why it matters: better cardiovascular resilience, calmer inflammatory responses and durable cell-membrane integrity.

Mineral Matrix: Spark-Plugs for Every Cellular Reaction

Minerals act as enzyme cofactors, structural reinforcements and electrically charged messengers—quietly powering metabolism, immunity and energy production. Here’s what each metric reveals:

Intracellular Magnesium

The workhorse behind 300+ enzymes, magnesium drives ATP creation, protein synthesis and precise nerve–muscle signalling while gating calcium channels to keep cells electrically stable.

Why it matters: steadier all-day energy, calmer nerves and reliable muscle–heart rhythm.

Zinc

Found at the core of more than 100 metabolic enzymes, zinc knits DNA, accelerates wound repair and primes antioxidant and detox pathways that keep cells resilient.

Why it matters: stronger immunity, faster recovery and a metabolism that stays on track.

Copper

Copper links iron to energy, forges connective-tissue strength and forms part of superoxide dismutase—one of your body’s frontline antioxidant enzymes. It also supports neurotransmitter and myelin creation.

Why it matters: healthier blood vessels and skin, balanced iron status and clearer neural communication.

Selenium

Built into glutathione peroxidase and other selenoproteins, selenium neutralises free radicals, regulates thyroid-hormone activation and tempers over-zealous immune reactions.

Why it matters: efficient metabolism, robust antioxidant defence and a well-calibrated immune system.

Ferritin (Iron Stores)

Ferritin reflects how much iron is banked in your tissues—iron that fuels oxygen transport, DNA construction and mitochondrial energy output, while also feeding neurotransmitter production.

Why it matters: sustained vitality, sharper cognition and immune cells that aren’t starved of oxygen.
