Oxidative Stress and Your Nerves: What Free Radicals Do and How Antioxidants Help

The hidden strain on your nervous system.

Quick answer

Oxidative stress happens when the body produces more free radicals, unstable molecules created during normal metabolism and increased by stress, smoking, pollution, high blood sugar and ageing, than its antioxidant defences can neutralise. Nerves are especially vulnerable because they use a lot of energy, are rich in fats (including the myelin sheath) that free radicals readily damage, and have limited ability to repair. Antioxidants from food, such as colourful fruits and vegetables, and nutrients like alpha lipoic acid, coenzyme Q10 and curcumin help maintain the balance. Healthy blood sugar, not smoking, exercise and sleep also reduce oxidative stress.

Key takeaways

Every cell produces free radicals as it makes energy. Nerves, with their high energy use and fatty coatings, feel the effects more than most.

Why nerves are vulnerable

FactorWhy it matters
High energy useMore mitochondrial activity, more free radicals
Fat-rich myelinEasily damaged by oxidation
Long fibresLarge surface area to protect
Limited repairDamage can accumulate

What increases oxidative stress?

High blood sugar

Excess glucose fuels free-radical production.

Smoking and pollution

Introduce large amounts of free radicals.

Chronic stress and poor sleep

Disrupt the body's antioxidant balance.

Ageing

Natural antioxidant defences decline.

How antioxidants help

Antioxidants donate electrons to stabilise free radicals. Alpha lipoic acid is notable because it works in both water and fat and recycles other antioxidants; CoQ10 protects mitochondria; curcumin adds further protection. Sciatilief combines all three with L-carnitine, magnesium glycinate and butcher's broom.

Food first: eat a colourful, plant-rich diet, keep blood sugar healthy, exercise regularly and don't smoke. Talk to your doctor before taking supplements if you use medication.

Common questions

What is oxidative stress?

An imbalance where free radicals outnumber the body's antioxidant defences.

Why are nerves vulnerable to oxidative stress?

They use lots of energy and are rich in fats that free radicals damage.

Which antioxidants support nerves?

Alpha lipoic acid, CoQ10 and curcumin are commonly studied.
