The human body is constantly exposed to environmental and internal factors that may contribute to cellular stress. One of the key processes involved in this is oxidative stress, which occurs when there is an imbalance between free radicals and the body’s ability to neutralise them.

Antioxidants play an important role in maintaining this balance and supporting overall health.

What are free radicals?

Free radicals are unstable molecules produced naturally in the body during processes such as metabolism. They may also be introduced through external sources, including pollution, smoking, and UV exposure.

Because they are unstable, free radicals can damage cells, proteins, and DNA through a process known as oxidative stress.

What is oxidative stress?

Oxidative stress occurs when there are more free radicals than antioxidants available to neutralise them. Over time, this imbalance may contribute to:

• Ageing
• Inflammation
• Cellular damage

The role of antioxidants

Antioxidants are substances that help neutralise free radicals, reducing their potential to cause damage.

Key antioxidants include:

• Vitamin C
• Vitamin E
• Various plant-based compounds found in fruits and vegetables

These nutrients help support cellular health and overall physiological balance.

How to support antioxidant defences

Dietary intake

A varied diet rich in colourful fruits and vegetables provides a wide range of antioxidants. Foods such as berries, citrus fruits, leafy greens, and carrots are particularly beneficial.

Lifestyle factors

• Limiting smoking
• Reducing excessive alcohol intake
• Protecting the skin from excessive sun exposure

Supplementation

In some cases, supplementation may help support antioxidant intake where dietary sources are insufficient.
