Understanding Oxidative Stress and Free Radicals
April 4, 2018
What Are Free Radicals?
Free radicals are unstable molecules that are missing an electron. To stabilise themselves, they take electrons from other molecules in the body, creating a chain reaction. This process is called oxidation — the same process that causes metal to rust or fruit to brown.
What Is Oxidative Stress?
Oxidative stress occurs when there are more free radicals than antioxidants can neutralise. This imbalance can damage cells, proteins, and DNA over time. Oxidative stress is associated with:
- Aging and cellular deterioration
- Inflammation
- Damage to skin, blood vessels, and organs
Where Do Free Radicals Come From?
Free radicals are produced both naturally and by external sources:
- Normal metabolism — The body generates free radicals as part of energy production
- Environmental factors — Pollution, UV radiation, cigarette smoke
- Diet — Processed foods and certain cooking methods can increase free radical exposure
The Role of Antioxidants
Antioxidants are molecules that can donate an electron to free radicals without becoming unstable themselves. This neutralises the free radical and stops the chain reaction. The body produces some antioxidants naturally (like glutathione), and we get others from our diet (like vitamins C, E, and polyphenols from plants).
Different Antioxidants for Different Needs
Not all antioxidants work the same way. Different antioxidants tend to act in different parts of the body:
| Antioxidant | Primary Sources | Notable For |
|---|---|---|
| Vitamin C | Citrus, berries, peppers | Immune support, skin health |
| Vitamin E | Nuts, seeds, vegetable oils | Cell membrane protection |
| Lutein | Leafy greens, egg yolks | Eye health |
| Lycopene | Tomatoes, watermelon | Prostate and heart health |
| Polyphenols | Olive oil, berries, tea | General cellular support |
C60 as an Antioxidant
C60 has been studied for its potential antioxidant properties. Laboratory research suggests its unique structure may allow it to interact with multiple free radicals. However, most research has been conducted in lab settings and animal models — human clinical data is limited.
Protecting Your Skin
UV radiation from the sun is a major source of free radicals that damage skin cells. While antioxidants (whether from diet, supplements, or skincare) can help support skin health, they are not a substitute for sunscreen and sun protection.
Key Takeaways
- Free radicals are a normal part of life, but excess amounts cause oxidative stress
- A diet rich in fruits, vegetables, and healthy oils provides a range of antioxidants
- C60 is an interesting antioxidant candidate, but human research is still in early stages
- No supplement replaces a healthy lifestyle, balanced diet, and medical care
