How to Prevent The Flu…Naturally

How to Prevent Flu
This was a friend’s post on Facebook recently,

My son had a complete psychotic attack – after taking two pills – hearing voices, talking gibberish and barricading himself because he thought we were going to kill him.

Why, you ask? Because he took Tamiflu.

And this is not uncommon. Japan banned Tamiflu in 2007 for just these kinds of side effects. 1

I encourage you to get serious about
taking your health into your own hands.

Your use of pharmaceutical drugs is usually in the best interest of the pharmaceutical companies, and I don’t believe the FDA has your best interest at heart either.

But I digress. That is not the reason for this post. I want to empower you with options both before AND after you get the flu…besides drugs. I particularly hope that if you choose some of the options below, you and your family will avoid getting the flu altogether.


You may think that the flu vaccine will keep you from getting the flu.

How to Prevent the FluNope!  After the 2012-2013 flu season, the CDC reviewed the flu vaccine’s effectiveness and found it to be just 56%, except for seniors, for whom the effectiveness dropped to just 9%! 2

You can get the flu vaccine, and there’s still a strong chance you’ll get the flu.

So why not protect yourself in a much more reliable way?
Naturally strengthen yourself to prevent getting the flu.
You’ll feel better and you won’t risk the potentially life-threatening side effects of vaccines or drugs like Tamiflu.

Your quickest approach is to eat a healthier, more nutrient-rich diet. Eliminate processed foods, junk foods and sugary treats. Eat foods as close to the way nature provides them as possible.

How to Prevent the FluIntroduce foods such as bone broth, fermented foods (like sauerkraut), and fermented cod liver oil (CLO) which provide you with the vitamins and fatty acids that help reduce inflammation and support your immune system. They’ve been used in traditional societies for years and seem to have some unexplainable quality that makes them powerfully effective.

My kids have never gotten the flu and I’ve given them fermented CLO regularly in the past. Now as teenagers, it’s hit or miss whether they take it. The simplest option, though, is easy-to-swallow capsules.


Vitamin D helps protect against viruses and bacteria. 3

Vitamin D is a key component in strengthening immune function and we just don’t get enough of it. In 2010, a study confirmed the effectiveness of Vitamin D in preventing the flu. Children taking only 1200 IU’s a day of D3 (not that much – I take 5000 IU’s) were 42% less likely to get the flu. 4

Have your Vitamin D levels tested. Per the Vitamin D Council, the correct test is 25(OH)D, also called 25-hydroxyvitamin D, and the recommended range for results is between 50-70-ng/ml. I usually need more than 5000 IU’s a day to reach that range.


And did you know it’s estimated that over 80 percent of your immune system is in your gastrointestinal tract?

To fight off foreign invaders, it’s crucial to have plenty of beneficial bacteria. Taking a high-quality probiotic will help your gut flora, as will adding fermented foods, such as sauerkraut, or any fermented vegetables, to your daily diet.

A very helpful book on do-it-yourself fermenting is Wild Fermentation by Sandor Katz.


Additionally, if you choose to continue eating sugar, you wreak havoc on your iHow to Prevent the Flummune system.

I’ve heard it said that sugar suppresses your immune system for approximately 6 hours after consuming it. Eating sugar at every meal then suppresses your immune system all day long! You’re a perfect host for a hungry virus.

Sugar also feeds the bad bacteria in your gut, making them stronger, so to stay healthy it’s a good idea to banish the white stuff. Use stevia instead of sugar in cooking and baking as a great alternative. If you’d like to read more about the effects of sugar on your immune system and overall health, you can read this.


If you’ve added some fermented foods to your diet, reduced or eliminated sugar, and increased your Vitamin D, you’re off to a great start. Additionally, certain supplements also support and enhance your immune system.


One of my favorite supplements to take is Vitamin C.

Vitamin C is a major antioxidant, and it works to combat infectious diseases like the flu, particularly viral ones. In fact, Vitamin C expert Dr. Thomas Levy has written numerous articles and books on the ability of Vitamin C to treat incurable infectious diseases. 5

Do your own research to determine an effective dosage, and I would highly recommend getting the purest Vitamin C you can afford. Your risk of getting sick will lessen though, and if you do get sick, your recovery will likely be much quicker. The brand I like best, which is biocompatible and very absorbable, is Beyond Health’s Vitamin C powder.

In China, people drink herbal teas all through the winter in order to prevent colds and flu.

One of their most common (and most effective!) remedies is Yin Qiao San.

I’ve got it in my cupboard and if somHow to Prevent the Flueone in our family shows a hint of a cold, I start handing it out like clockwork. You can check this site out which details the varying symptoms of a cold or flu and the different herbal combinations that treat them. What I love about Chinese Medicine is the focus on naturally strengthening your body by addressing the root of your issue rather than just masking your symptoms.


Other over-the-counter herbal supplements that are well-known for colds and flu particularly affecting the respiratory tract, are Echinacea, Goldenseal, Elderberry and Slippery Elm. Ginseng has shown to be effective at curing a cold or flu, and White Willow is a natural anti-inflammatory and fever reducer. 6

How to Prevent the Flu

I’m also a big fan of homeopathy, and both Phosphorus and Arsenicum have been shown to help with stomach upset when someone also has difficulty keeping water down. The correct homeopathic remedy is very specific to the symptoms one is experiencing, so consult with a homeopath or a homeopathic resource before taking one.

I’ve consulted this book many times in my days as a mom.


And finally, the obvious measures to help keep your immune system healthy and strong include getting plenty of sleep, exercising regularly, washing your hands often with regular soap (not the anti-bacterial stuff!), keeping your hands away from your nose and mouth (don’t pick your nose!), and coughing or sneezing into your elbow.


I know this was a long post, and there’s plenty more that I could have included. But, I hope you find this information useful to boost your immune system function and keep yourself and your family healthy this winter.

May you be authentically healthy!

  1. Great post Alicia! I make a delicious elderberry elixir every year to help ward off colds and flus at our house. That, along with a big batch of fire cider/master tonic always does the trick for me!

    Thanks Vanessa! I love that you make elderberry elixir yourself. And a friend of mine was just mentioning that she’d made a batch of fire cider for the first time. Glad to hear that it works so well for you. I’ll pass that news along to her. In case anyone is curious, here is a recipe for fire cider:
