What Is Oxidative Stress & How Does It Affect the Body?

Oxidative stress is a major factor in premature ageing—but don’t worry. Here’s how you can combat it with the right nutrition.

3 MIN READ — 04/10/2025

Oxidative stress—it sounds like an invisible enemy quietly attacking your health, and in many ways, it is. When the balance between free radicals and antioxidants in your body tips, your cells can suffer serious damage. But don’t worry, you don’t have to sit back and watch it happen. We’re here to show you how the right diet can help you fight back against oxidative stress.

At a Glance

  • 01.

    Oxidative stress is a serious adversary for your health.

  • 02.

    Antioxidants are your best allies in keeping free radicals in check. Vitamins like C and minerals such as zinc and copper help reduce oxidative stress.

  • 03.

    Alongside a balanced diet, getting enough sleep, practising relaxation techniques, and staying active are crucial for effectively managing stress.

What is Oxidative Stress?

Imagine an invisible battle raging inside your body. On one side are the free radicals, highly reactive particles eager to attack your cells and DNA. On the other side are the antioxidants, or your body’s heroes, ready to neutralise those radicals. When this balance is disrupted and the radicals take over, you’re dealing with oxidative stress—a condition that can seriously harm your body.

Oxidative Stress and Its Symptoms

Your body sends out signals when it’s under oxidative stress. You just need to know how to read them: Do you feel constantly tired, even when you’ve had enough sleep? Struggling with memory lapses or concentration issues? These, along with other symptoms like skin problems, hair loss, muscle pain, or mood swings, could be your body’s way of telling you it’s dealing with oxidative stress.

How Does Nutrition Play a Role in Oxidative Stress?

Your diet is more than just fuel, it’s your most powerful tool in the fight against oxidative stress. Foods rich in antioxidants help keep free radicals in check and protect your cells. Vitamins like C and E, along with minerals such as zinc, selenium, and copper, are the heavyweights in this battle. By intentionally incorporating these nutrients into your diet, you’re giving your body exactly what it needs to stay healthy.

These Antioxidant-Rich Foods Should Be on Your Radar

If you’re looking to boost the antioxidants in your body through diet, there are plenty of options to add to your meals. For quick reference, here are some of the most essential foods:

What Habits Can Help Prevent This Type of Stress?

A healthy diet is the first step, but there’s more you can do to keep oxidative stress at bay. Think of your life as your personal wellness programme: getting enough sleep, practising regular relaxation techniques like meditation or yoga, and maintaining strong stress management are your allies. Avoid harmful influences like smoking, which ramps up free radical production, and ensure your body stays hydrated. These simple yet effective habits can make a significant difference.

Does Oxidative Stress Affect the Ageing Process?

Oxidative stress isn’t just a risk to your health—it can also speed up the ageing process. Since oxidative stress can damage the cells in your body, your skin may be affected too. Loss of elasticity, increased wrinkle formation, and the appearance of age spots can all be consequences. Free radicals can also weaken your immune function, making you more susceptible to illness. Changes in cellular metabolism are possible as well, potentially slowing down cell regeneration. Chronic diseases, particularly cardiovascular issues, may become more common as oxidative stress damages your blood vessels. In short, oxidative stress can have a profound impact on your overall health.

↡ Ongoing survey of 3,000+ AG1 customers after 12+ days of use, 2024.

§ In a third-party, observational study conducted on 35 healthy adults ages 25-48 assessing the self-perceived efficacy of AG1 over the course of 3 months. The study was conducted on a similar version of AG1's continually evolving formulation. The study results are transferable because of comparable ingredients and amounts.

○ Ongoing survey of customers from 12 European countries who have been taking AG1 for an average of 9 days.

⬥ AG1 single subscriptions price and dose-matched average aggregated prices in 9 individual nutritional supplement categories with comparable ingredients. The prices of the individual supplements are the average prices of three individual products available online for each compared category, each with comparable ingredients. To ensure a fair basis for comparison, where the comparison products have different dosages, the prices were mathematically adjusted to correspond to the dosage contained in AG1. The 9 compared categories are vitamin B12, folate (Methylfolate), vitamin C, vitamin E, bacterial cultures, zinc, coenzyme Q10, greens powder and fibre.

Research Studies
a. In a triple-blind, randomised, placebo-controlled parallel-designed clinical trial evaluating nutrient biomarkers and microbiome shifts in 105 healthy adults ages 20-59 over the course of 12 weeks.
b. In a double-blind, randomised, placebo-controlled 2-week cross-over clinical trial assessing microbiome shifts in 20 active adults ages 19-37.
c. In a double-blind, randomised, placebo-controlled 2-week cross-over clinical trial assessing microbiome shifts of 24 healthy adults with occasional GI distress ages 26-59.
d. In a double-blind, randomised, placebo-controlled cross-over clinical trial assessing bioavailability in 16 healthy adults ages 18-42 over the course of 8 hours.
The studies were conducted on a similar version of AG1's continually evolving formulation. The transferability of the study results is ensured because of comparable ingredients and amounts.
