Let's Talk About Antioxidants and Antibodies

Antioxidants and antibodies are both important components of the human immune system, working together to protect the body against harmful pathogens and promote overall health. While they serve different functions, their roles are interconnected and can have a significant impact on the body's ability to fight off disease.

Antioxidants: What They Do

• Neutralize free radicals, which are highly reactive molecules that can damage cells and contribute to disease.
• Free radicals are generated naturally during metabolism but also come from external factors such as toxins, radiation, and cigarette smoke.
• Antioxidants donate electrons to free radicals, neutralizing them and preventing cell damage.¹

Sources of Antioxidants

• Found in many foods, especially fruits and vegetables.
• Can also be taken as supplements.
• Common antioxidants include vitamins C and E, beta-carotene, and selenium.
• Research shows antioxidants are associated with a lower risk of chronic diseases, such as heart disease, cancer, and Alzheimer’s disease.²

Antibodies: How They Work

• Proteins produced by the immune system in response to specific pathogens (viruses, bacteria).
• Recognize and bind to molecules on pathogens, marking them for destruction by immune cells.³
• This process, known as the immune response, is essential for protection against infection.

Antibodies and B Cells

• Antibodies are produced by B cells (a type of white blood cell).
• When B cells encounter a pathogen, they create antibodies tailored to that pathogen.
• Antibodies then bind to the pathogen and signal other immune cells to destroy it.⁴

Antioxidants and Immune Function

• Their role is less understood compared to antibodies.
• Research suggests they may support immune function by:
• Enhancing activity of immune cells.
• Improving the body’s ability to respond to infections.

Key Takeaway

• Antioxidants and antibodies are both vital for a healthy immune system.
• Antioxidants neutralize harmful free radicals, while antibodies directly target pathogens.
• A diet rich in antioxidant-containing foods, along with other immune-supporting habits, helps maintain a strong defense system and long-term well-being.
