How Antioxidants Can Help Improve Immune Health

At Well Theory, we’re obsessed with learning how to help you naturally improve your own health and well-being – We do this by giving you the tools to improve your diet, lifestyle, and more.

Growing scientific evidence has begun to suggest that antioxidants have the ability to assist in the prevention of certain diseases, improve cardiovascular function, and may even improve immune system function while slowing down the effects of aging.

Today, we’re going to explore how antioxidants improve your immune health with their free radical-scavenging powers.

First, What Are Free Radicals?

Understanding what free radicals are requires a quick chemistry lesson:

Atoms, the building blocks of matter, are surrounded by electrons. Each “layer” of electrons is called a “shell,” and only a certain number of electrons can fit into these shells. Once these shells are full, electrons find the next atom to fill.

If an atom has a shell that isn’t full of electrons yet, it may bond with another atom to use the electrons located in that atom’s shell. These types of atoms are called free radicals. Atoms with a full outer shell are stable and don’t “scavenge” for electrons, but these free radicals are unstable - they seek other atoms or molecules to bond to.

In your body, when oxygen molecules are processed and split into single atoms with unpaired electrons, they become unstable free radicals and “scavenge” the body searching for pairings. This leads to a process called oxidative stress. 

As free radicals move through the body, they can break down cells over time – damaging cells in virtually every part of the body, and leading to symptoms like headaches, fatigue, faster aging, and more. One way they do this is to destroy the outer layer (membrane) of a cell.

What Are Antioxidants?

Consider antioxidants the “cure” to the problem of free radicals and oxidative stress. 

Your body naturally produces antioxidants, but when you aren’t living a healthy lifestyle, eating a balanced diet, and generally taking care of yourself, it can struggle to produce enough antioxidants to regularly neutralize free radicals.

When free radicals outnumber your body’s natural antioxidants, you begin to feel the effects of oxidative stress.

How Oxidative Stress And Immune Health Are Related

In general, when your body is not under stress, it works better overall. So high antioxidant intake – particularly by eating dark-colored or brightly pigmented fruits and vegetables, is a great way to reduce the likelihood of oxidative stress and the damage it causes to cells throughout your body.

In addition, “Recent clinical trials have found that antioxidant supplementation can significantly improve certain immune responses.” 

This study found that certain vitamins, such as vitamins E and C are potent antioxidants. These essential micronutrients were found to directly interfere with the formation of free radicals and actively scavenge free radicals.

In particular, according to the data referenced in the study, Vitamin A supplementation was found to significantly reduce mortality associated with measles in children. The protective antioxidant effects of vitamin A were associated with improved immune response and reduction in the rate of secondary infections for up to 6 months.

Supplementation is a great way to improve your immune function – both through improved nutrition and directly supplementing with vitamins, minerals, and herbal remedies that are known to be highly antioxidant.

Our Herbal Immunity Defense supplement is designed to give your immune system a fighting chance. Developed with potent and highly antioxidant ingredients like Elderberry, Echinacea, Quercetin, and more – this supplement is surgeon-developed to give your immune health the added boost it needs to restore optimal function.
