Inflammation is often called the root of all disease — and for good reason. From heart disease to depression, fatigue to fertility problems, inflammation plays a role in nearly every chronic condition. But inflammation isn’t always visible. You can’t always feel it.
So how do you know if your body is inflamed?
That’s where blood testing comes in — particularly through nutritional biomarkers. While traditional medicine might look at CRP or white blood cell counts, functional nutrition goes deeper: by assessing your levels of Omega-3, Vitamin D, Homocysteine, Glutathione, Amino Acids, and other markers that influence inflammation at the cellular level.
This blog unpacks the inflammation-nutrition connection and shows how a simple at-home test can reveal the silent signals of chronic inflammation — before they become bigger health problems.
What Is Inflammation?
Inflammation is your body’s natural defense response. When you’re injured or infected, inflammatory cells rush to protect and heal you.
But when inflammation becomes chronic, it can damage tissues, disrupt hormones, trigger autoimmune conditions, accelerate aging, and contribute to:
-
Brain fog and low mood
-
Digestive problems
-
Joint pain and stiffness
-
Fatigue and burnout
-
Weight gain and insulin resistance
-
Cardiovascular disease
The good news? Nutritional imbalances are often both a cause and a solution to chronic inflammation.
Key Nutrients That Influence Inflammation
Let’s explore the top nutritional biomarkers linked to inflammation — and how you can test them using dried blood spot kits.
1. Omega-3 Index
Omega-3 fatty acids (EPA and DHA) are powerful anti-inflammatory agents. They compete with pro-inflammatory Omega-6s (like arachidonic acid) and influence key mediators like prostaglandins and resolvins.
A low Omega-3 Index is associated with:
-
Higher systemic inflammation
-
Cardiovascular risk
-
Poor recovery and immune dysregulation
📌 Test with:
2. Vitamin D
Vitamin D modulates both innate and adaptive immunity. It suppresses inflammatory cytokines like TNF-alpha and IL-6 — which are elevated in many chronic inflammatory diseases.
Deficiency in Vitamin D is linked to:
-
Autoimmune conditions
-
Mood disorders
-
Bone and muscle inflammation

3. Homocysteine
Homocysteine is a byproduct of methionine metabolism and a red flag for vascular inflammation. High levels are associated with:
-
Endothelial dysfunction
-
Oxidative stress
-
Increased risk of stroke, dementia, and cardiovascular disease
📌 Test with our Homocysteine Test
4. Glutathione Index
Glutathione is the master antioxidant, neutralizing free radicals and maintaining redox balance. When oxidative stress is high and glutathione is low, inflammation rises.
Low glutathione status may be involved in:
-
Immune dysfunction
-
Autoimmune disease
-
Accelerated aging and chronic fatigue
📌 Test with our Glutathione Index Test
5. Amino Acids
Certain amino acids, like glycine, cysteine, and glutamine, are crucial for inflammation control and tissue repair. Amino acid deficiencies can impair detox pathways, reduce glutathione synthesis, and increase inflammatory load.
Look out for:
-
Low glycine → increased oxidative stress
-
Low cysteine → impaired detox
-
Low arginine → poor immune function
📌 Test with our Amino Acids Test
6. CoQ10
While not traditionally considered inflammatory, CoQ10 plays a vital role in mitochondrial function. When mitochondria are dysfunctional, cells release signals that promote inflammation.
Low CoQ10 may result in:
-
Fatigue
-
Brain fog
-
Poor cardiovascular function
-
Slow tissue recovery
📌 Test with our CoQ10 Test
What Causes Chronic Inflammation?
-
Poor diet (high sugar, processed oils, trans fats)
-
Nutrient deficiencies
-
Gut dysbiosis or leaky gut
-
Chronic stress
-
Environmental toxins
-
Sedentary lifestyle
-
Overtraining or lack of recovery
Nutritional testing helps you uncover what’s driving your inflammation — so you can address it with precision.
Symptoms of Chronic Low-Grade Inflammation
-
Fatigue and low energy
-
Brain fog or poor concentration
-
Digestive issues (bloating, IBS)
-
Achy joints or stiffness
-
Puffy face or fluid retention
-
Frequent colds or slow recovery
-
Skin issues (acne, eczema, psoriasis)
If you tick more than one box, your blood may hold the answers.
Why At-Home Testing Works
Our at-home test kits use dried blood spot (DBS) collection — fast, easy, and accurate. You collect a small sample from your fingertip and mail it in. Lab analysis then gives you:
-
Your biomarker results
-
Optimal reference ranges
-
Interpretation based on inflammation and health risk
-
Nutrition and lifestyle recommendations
No doctor appointment. No waiting room. No guesswork.
Next Steps: What to Do After Testing
Once you’ve identified inflammation-related imbalances, you can take targeted action:
✅ Adjust your diet — increase anti-inflammatory foods like oily fish, leafy greens, turmeric, and berries
✅ Add supplements where needed — omega-3s, vitamin D, methylated B vitamins, NAC, CoQ10
✅ Address lifestyle — improve sleep, reduce stress, support gut health, move your body
Your blood data is your health compass — let it guide you.
Final Thoughts
You don’t have to guess whether your body is inflamed. Nutritional blood testing helps you see the early signs before they turn into full-blown issues.
Whether it’s Omega-3, Vitamin D, Homocysteine, or Glutathione — the right test can uncover the invisible root causes of fatigue, pain, and dysfunction.
Get ahead of inflammation. Take control of your health from the inside out.
