Antioxidant & Cellular Health

Antioxidants work as a network, not in isolation. Glutathione recycles vitamin C and E, CoQ10 protects mitochondrial membranes, NAD+ powers cellular repair, and omega-3 fatty acids stabilise lipid membranes against oxidative damage. Testing across this network gives you a far clearer picture of cellular health than measuring any single marker alone.

What this collection tests

• Glutathione Index — The body's master antioxidant. Low glutathione is linked to chronic inflammation, oxidative stress, and accelerated cellular ageing.
• CoQ10 (Coenzyme Q10) — Essential for mitochondrial energy production. Levels naturally decline with age, particularly after 40, and are commonly low in people on statin medication.
• NAD+ Index — A trending longevity biomarker. NAD+ powers DNA repair, mitochondrial function, and cellular energy metabolism.
• Omega-3 Index (Basic, Ratios, and Complete) — EPA and DHA protect cell membranes from oxidative damage and modulate inflammation.
• Amino Acids — The building blocks of glutathione synthesis. Suboptimal amino acid status often underlies low glutathione.

Why test the antioxidant network

Oxidative stress contributes to nearly every chronic disease process — cardiovascular disease, neurodegeneration, type 2 diabetes, and cancer all involve unchecked free radical damage. Testing your antioxidant status reveals where your defences are strongest and where they may need support.

This is particularly valuable if you experience chronic fatigue, are recovering from illness, are over 40, or are pursuing longevity-focused supplementation. Testing first prevents the common mistake of supplementing aggressively with antioxidants you already have plenty of, while leaving genuine deficiencies untreated. Our guide to the antioxidant network covers how these markers interact and which to prioritise based on your specific goals.
