5 Signs of Oxidative Stress and 7 Ways You Can Stop It


Dr Doni highlights one of our best strategies for preventing cancer – preventing oxidative stress.

The term “oxidative stress” is mentioned all the time in the realm of science and nutrition, but it is not often clear what it means for your health. In fact research indicates that oxidative stress is an underlying cause of cancer, so understanding and preventing it is a smart strategy for your wellness.

Today, I’m going to explain what it is, give you some signs to look out for, and some simple steps you can take to prevent it.

What is Oxidative Stress?

The process of oxidation happens as our bodies metabolize (or process) the oxygen that we breathe and our cells produce energy from it. This process also produces free radicals –which interact with the molecules within our cells resulting in damage (or stress) to nearby cells, mitochondria, and DNA (our genes).

Free radicals are normal and necessary to some degree. In addition to causing some damage, they also stimulate repair. It is only when the amount of free radicals produced overwhelms the repair processes that it becomes an issue. That is what we call oxidative stress.

Oxidation happens under a number of circumstances including:

In fact, there are millions of processes taking place in our bodies at any one moment that can result in oxidation.

Oxidation increases when we are physically and/or emotionally stressed. And as long as you have enough anti-oxidants, a careful balance is maintained and damage is prevented.

Oxidative stress happens when the amount of free radicals exceeds the amount of antioxidants. That’s when oxidation damages our cells, proteins and our DNA (genes).

How Do You Know If You Have Oxidative Stress?

Here are a few signs to look out for:

  1. Fatigue
  2. Memory loss and/or brain fog
  3. Muscle and/or joint pain
  4. Wrinkles and grey hair
  5. Decreased eye sight
  6. Headaches and sensitivity to noise
  7. Susceptibility to infections

Oxidative stress has also been associated with numerous health conditions including chronic fatigue syndrome, fibromyalgia, diabetes, Alzheimer’s disease, anxiety, insomnia, cancer, and more. I feel so strongly about helping you address and prevent these conditions that I decided to write a whole blog series about oxidative stress covering a different condition in each article. Find that blog series here.

How to Reduce Oxidative Stress

There are two ways to reduce oxidative stress. Avoid exposure to unnecessary oxidation and increase your anti-oxidants. Let’s look at each of these in turn.

Decreasing Exposure to Oxidation

As I said at the top of this article, oxidation increases when we are exposed to stress, toxins, and infections. It is also increased by sugar and chemicals, so the more you can minimize your exposure to these things, the better.

Choosing organic foods and avoiding toxins in your environment makes a big difference. Reducing stress helps too and can be done with what I refer to as “daily stress remedies”. Here are four steps you can take to reduce unnecessary oxidation in your body.

Step 1: Avoid sugar and processed foods while balancing your blood sugar levels

When the body has to process sugar it also creates oxidation and the more sugar we eat, the more oxidation happens. Processed foods often contain sugar and/or other chemicals that also result in oxidation. Eating large and infrequent meals also creates more oxidative stress, so balancing your blood sugar by eating smaller, frequent meals, also helps. To learn more about how to avoid sugar and to balance your blood sugar, click here.

Step 2: Prevent infections

When the immune system is fighting off an infection, it ends up creating oxidation which is why, when you get sick, it drains your body of energy. I encourage you to have a strategy to avoid catching colds and infections – sign up to receive my cold/flu survival guide here, and if you have been getting frequent infections, let’s meet and come up with a plan to prevent another. You can book an appointment here.

Step 3: Allow time for daily stress remedies

It seems so simple, but it really pays off. That’s why you need to build breaks into your day – to give your body a chance to recover. Be sure to honor the breaks in your schedule (or create them) and take them as a chance to enjoy the outdoors, breathe, and re-center. These are some ideas for daily stress remedies:

Step 4: Avoid toxins

Choose organic foods and avoid cigarettes, candles, hair and nail salons, carpet, exhaust fumes and plastic. Check your personal care and cleaning products for toxic ingredients and replace them with non-toxic alternatives.

Learn more about toxins in personal care products and how to avoid them here. For complete details on how to reduce your toxic exposure, be sure to check out Chapter 8 of my book The Stress Remedy.

Increasing Anti-Oxidants

No matter what you to do avoid them, you are going to be exposed to some toxins and stress, so your next step is to increase the anti-oxidants you have in your system either by helping your body make more, or by consuming them in food or supplements*.

What anti-oxidants do is block oxidation. They squelch it and make it non-harmful!

Here are the final three steps you can take to combat oxidative stress. These are all ways of increasing the anti-oxidants in your system:

Step 5: Promote the production of anti-oxidants

One of the most powerful anti-oxidants is glutathione which is produced by the body. It is made from three amino acids – glycine, glutamate, and cysteine – and it contains sulfur, which is what makes it so effective.

Eat foods that help your body to make more glutathione include:

You can also support your body to make more glutathione by eating foods that are high in sulfur:

Or you can take supplements that contain:

These supplements have also been shown to increase and maintain glutathione:

It would be too much to take each of these supplements separately, so I encourage you to find a combination product. Of course it is always important for you to know your health and to choose carefully for your body, with the help of a health care provider. Here are a couple examples from companies that I trust:

Antioxidant Formula

Glutathione Recycler

Or even a high quality multivitamin containing antioxidants, such as MultiONE.

There are also supplements containing actual glutathione, which is especially helpful when your levels are low and if you have genetic SNPs that may cause your levels to become depleted.  It is important to choose a product that is either sustained release (see an example here) or has non-soy, non-GMO phosphatidylcholine to increase glutathione absorption (see an example here).

Step 6: Eat foods that are high in anti-oxidants

You can add to what your body produces by eating foods that are high in anti-oxidants every day. These tend to be the foods that are the most colorful, for example:

Other good sources of anti-oxidants include:

And herbs such as:

The more anti-oxidants you eat, the better you can counter oxidation and prevent oxidative stress.

Step 7: Take herbs that are high in anti-oxidants

Research indicates that the four leading herbal sources of anti-oxidants are:

Find a product with all of these herbs in one here.

Other useful antioxidants in supplements that can be taken daily, either separately or together, for ongoing support are:

You can also find many more supplements containing anti-oxidants at in the anti-oxidant category here.

Protect Yourself From Oxidative Stress

Now you’ve got it. Protecting yourself from oxidative stress is as simple as protecting your cells by providing what your body needs and avoiding what it doesn’t need.

Knowing that we are all exposed to stress and toxins, and potentially infections, on a daily basis, choosing ways to reduce stress and increase anti-oxidants will help you prevent cancer and to live a longer, healthier life.

If you’d like one-on-one help to address oxidative stress, I encourage you to contact a naturopathic doctor. I offer a special consultation package specifically to help address oxidative stress. Read about it here.

*Please keep in mind that any and all supplements—nutrients, herbs, enzymes, or other—should be used with caution. My recommendation is that you seek the care of a naturopathic doctor (with a doctorate degree from a federally-accredited program) and that you have a primary care physician or practitioner whom you can contact to help you with individual dosing and protocols. If you ever experience negative symptoms after taking a product, stop taking it immediately and contact your doctor right away.
