8 Natural Cold & Flu Prevention Tips

September 15, 2013

Would it be like a dream to get through cold and flu season without a trip to the doctor, or a round of antibiotics?


It doesn’t have to be a dream.  Yes, the cold and flu season is looming upon us, and has already started for some.  But instead of feeling like a sitting duck – instead, why not go on the offensive with some natural ways to boost immunity (that don’t involve getting a shot)!  As the expression goes “an ounce of prevention is worth a pound of cure.

Here are some tips to help you stay a step ahead of colds & flu this year.

8 Natural Cold & Flu Prevention Tips


1. Get Your Sunshine Vitamin

Do you get several colds every year?  That could be an indication that your vitamin D levels are too low.  Perhaps one of the most important things we can do to prevent colds and flu – is to optimize our vitamin D levels.  Vitamin D is not really a vitamin, but a pre-hormone produced in the skin after exposure to the sun’s UVB rays.  So vitamin D levels typically drop in the Fall/Winter months when we get less sun exposure. A study published in 2009 in the Archives of Internal Medicine, found that 70% – 97% of Americans have insufficient blood levels of Vitamin D.  Vitamin D is known for it’s role in building strong bones, but it also plays a significant role in our immunity – in fact, our immune system requires vitamin D in order to properly function (read: Immune System Superstar-Vitamin D).  Some research shows that vitamin D is more effective in preventing the flu than a flu shot.  To get ready for cold and flu season – the Fall/Winter is a good time to supplement with vitamin D3 (read: Are You Getting Enough Vitamin D?). Low levels of vitamin D not only raise our risk of colds and flu, but also increases our risk for breast cancer, fractures, depression, heart disease, Alzheimers disease, and more.  These Nordic Naturals Vitamin D3 gummies are a great option for kids, and I like this one from Pure Prescriptions for adults, it features VESIsorb® Delivery System for optimal absorption.  Ideally, you should have your levels checked twice yearly to know if you are supplementing at the right dose.  Optimal blood levels of vitamin D should be between 40 ng/dL – 60 ng/dL, and are very  important for cancer prevention, learn more.  Getting your vitamin D in the optimal range could literally save your life – as low vitamin D is associated with an increased risk of cancer and other diseases.Experts say that 70% of breast cancers could be prevented by optimal blood levels of vitamin D.  I always recommend taking vitamin D with magnesium – because it is needed for the conversion to the active form.

2. Boost your (Good) Bacteria!

Our bodies are teeming with bacteria, in fact, according to scientists, we have 10 times more bacterial cells than human cells!  And it is important for us to remember that some of those bacteria are the “good guys,” which are important not only for our digestion, but also for our immune system, and even our mental healthStudies show that probiotics are a very powerful tool in the fight against infection. So if you want to boost your immune system, increase the good bacteria in your gut by eating probiotic rich foods, and/or taking a probiotic supplement.  According to this article, “a healthy lower intestine should contain at least 85% friendly bacteria to prevent the over-colonization of microorganisms like E. coli and salmonella. Replenishing the healthy bacteria in our gut is especially important after a course of antibiotics – critical really – because they wipe out ALL the bacteria – good and bad.  So although antibiotics can help to get rid of an infection like strep throat, they can leave your immune system vulnerable to future infections.  My preferred probiotic is Pure Encapsulations – Lactobacillus Sporogenes (Bacillus Coagulens), because it is well tolerated and does not tend to cause bloating or discomfort.  It is also shelf stable – so no refrigeration required. It can get past the harsh stomach acid to get to work in the large intestine where it should be.  Read The Importance of Good Bacteria to learn more.

3. Wash Up!

Whenever you put a bunch of kids together in a room, you increase the chances that viruses and bacteria can spread.  One of the best ways to prevent germs spreading around is to simply wash them off!  One of the simplest things our kids can do to prevent getting sick is to simply wash their hands. Because viruses can live for up to 48 hours on a surface, so remind your kids to make sure to wash their hands before they eat, or when they come into the home from being out in public places touching surfaces. Also remind your kids to not put their hands (or toys) in their mouths.

Do your kids do the ‘quick rinse’ in the sink without soap?  I know a lot of kids do – they are far too busy to wash with soap.  But a quick rinse with water might not get all the germs off.  So hands should be washed with soap and water after using the bathroom, before eating, and after handling things in public places (ie: playground, museums, grocery stores, health clubs).  But just say no to the antibacterial soaps!  Studies show that use of the anti-bacterial agent Tricolsan  (found in many antibacterial soaps, gels, and wipes) could be creating resistant strains of bacteria.  So don’t forget to wash hands, but stick with regular soap.

4. Get Some Vitamin C

Ever since Nobel prize-winning scientist Linus Pauling wrote the book Vitamin C and the Common Cold in 1970, the debate about whether or not it can help prevent the common cold has raged on.  But research does shows that vitamin C is a powerful antioxidant that can support a healthy immune system.  So during the cold and flu season – load up on the citrus fruits, strawberries, and red peppers.  It is also a good idea to supplement with vitamin C as well.   This is the brand of vitamin C that I take every day, I also like Trace Minerals Research Electrolyte Stamina packs – they pack 1,200 mg of vitamin C, and come in a variety of delicious flavors – great for kids that can’t swallow pills. Take vitamin C with food if you have a sensitive stomach or it gives you loose stools, or consider lipospheric vitamin C.  Some people with constipation find that 1,000 mg. of vitamin C in the morning before breakfast solves all of their constipation woes.   Read: Was Linus Pauling Right About Vitamin C’s Curative Powers After All?

5. Get your ZZZs (sleep)

Sleep is when our body recovers, regenerates and repairs – several different studies have shown a link between lack of sleep and lowered immune system. Adults should get no less than 7 hours of sleep. Kids need different amounts depending on their age. But they should be getting to bed early enough each night that they wake up feeling refreshed. Turning off electronics 1 hour before bedtime helps people settle down to sleep better. – because the blue light emitted from screens intereferes with the body’s production of melatonin, a sleep hormone.

6. Cut out the sugar

One of the worst foods for our immune system are sugary foods and drinks. Studies have shown that ingesting a sugary solution reduced white blood cell effectiveness by 40%, thereby reducing the body’s ability to fight infection. Sweets also increases systemic inflammation in the body, and create imbalances in our gut bacteria, which are both important players in the immune system. So try to cut back on the sweets this time of year to boost immunity (easier said than done with Halloween around the corner!).  If you are struggling with a sugar addiction, consider my Break up with Sugar eCourse!

7. Lower stress levels.  

Stress can lower the immune system, making the body less effective at fighting infections.  So doing things like yoga or meditation to reduce stress levels will help to boost the immune system.  If possible – giving kids downtime away from homework and other commitments to just have some fun – also helps to lower stress levels too.   Kids (and adults) need play time!

8. Take some olive leaf extract

Great for prevention of colds and flu this time of year, Olive leaf is a powerful antioxidant immune support with an ORAC score of 7608.  The use of olive leaf extract to support health dates back to ancient Egypt. You can buy liquid, capsules, and even a throat spray – which is great at the first signs of a sore throat, often the early stage of a cold or flu.

Already Feel a Cold Coming On?  Nip it in the Bud!

So what should you do if you start to feel a sore throat, or other symptoms of a cold of flu?  In addition to the above, there are a number of natural things that we like to do to stop a cold in it’s tracks!

1. Take some natural antibacterials

Garlic and oregano – are both powerful antiviral and antibacterials – if you catch it early enough, at the sore throat stage – I have found that taking some oregano oil can really nip a cold in the bud – the brand we use in our house is Gaia Oregano Oil.  We always have some on hand in case we feel a cold coming on!  I also like to take Immune Shield from Sun Warrior.  Immune Shield contains ionic liquid silver and gold in a fulvic acid base. Silver is also a very effective natural anti-bacterial.  If you catch it at the early stage – taking natural anti-bacterials can help to prevent a virus from taking hold, or progressing into a more serious infection.  But do not take oregano oil for longer than about 2-3 weeks – like other antibacterials – it can affect both the good and bad bacteria in your gut.

2. Take a homeopathic cold remedy.

The minute I feel a sore throat coming on – I reach for my Boiron ColdCalm. If you catch it early enough – homeopathic remedies can really help to stop a cold, or at least lessen the symptoms.  If you do not catch it early enought to prevent – homepathic remedies are also natural ways to manage the pain and inflammation, and help to drain the mucous membranes.  Some homeopathic formulas can be found over the counter at your local health food store (such as Boiron ColdCalm or UMCKA Cold+Flu, or ), or look for a practitioner that offers homeopathic remedies.  Start these at the first sign for best results – we always have Cold Calm on hand in the house just in case!

3. Boost the Vitamin D, zinc, and push the Vitamin C.

If your immune system is fighting a virus, supporting it with additional C, D and zinc is helpful.  Vitamin C, zinc, and vitamin D are all important players in the immune system.  So if you seem to get every cold and flu that you come into contact with – you could be deficient in vitamin D or zinc.  I recommend having your vitamin D levels checked each year, especially if you are prone to getting colds.  If you do supplement with vitamin D, always take it with magnesium – needed for the conversion.  This is the magnesium we take at our house- Designs for Health Magnesium Malate.

One of the most powerful forms of vitamin C that I have found is Lypo-Spheric Vitamin C.  We have used it in our house to help recover from those stubborn coughs that just seem to linger on and on (they didn’t linger as long using this).  Lypo Spheric products use phospholipids to maximize absorption. Phospholipids are primary building blocks of the cellular membrane: the thin, protective wall around each cell in your body – the wall functions as a skin for each cell, keeping things in or out. While your body can make some phospholipid compounds on its own, others must be supplied by your diet. These are called essential phospholipids. Lypo Spheric Vitamin C gives you 1,000 milligrams of Vitamin C AND 1,000 milligrams of Essential Phospholipids in each packet, including Phosphatidylcholine, an important phospholipid required for maintaining a healthy cardiovascular, reproductive, immune, collagen, and nervous system.  Lipospheric vitamin C is one of the most powerful ways to get vitamin C into the cells, nearly as powerful as IV vitamin C – which saved a man dying from pneumonia – his family was given no hope, but IV vitamin C (and lipospheric vitamin C when the doctors refused to give it by IV) brought him back – watch this amazing story called – “Vitamin C The Miracle Swine Flu Cure” – about how a dairy farmer who had “white out” pneumonia complications from the Swine Flu – his life was literally saved by vitamin C.  High dose IV Vitamin C may also help with recovery from other immune issues like shingles and lyme disease.

4. Make a big batch of chicken soup, or buy some organic chicken bone broth!!

Organic slow-cooked chicken soup made with bones is not just comforting and good for the soul – it provides collagen which helps to support immunity and gut health, it also has electrolytes which help to keep the body hydrated too.

5. Get your rest!

Lack of sleep can leave us feeling run down and prone to illness.  So if you are feeling something coming on – try to get to bed early and get some ZZZs, so the body can recover.

6. What to do if you need to take antibiotics.

If you end up with a bacterial infection, or you need to take antibiotics to get well – then be aware that the antibiotics are not selective – they kill the good bacteria along with the bad.  So you will want to replenish the good bacteria in your gut by taking a probiotic (or you will find your immune system to be more vulnerable).  I have a two pronged approach for this:

During antibiotic use and for a short time afterwards – take Jarrow brand Saccharomyces Boulardii. Because it is a beneficial yeast (not a probiotic), it will not interfere with, or be killed off by the antibiotic.  Saccharomyces Boulardii has been shown to be protective against diarrhea (which antibiotics can cause), and also to help create a beneficial environment in the gut.

After antibiotic use – I recommend a soil based probiotic – to help “reseed” the good bacteria in the gut.  My favorite one is Pure Encapsulations – Lactobacillus Sporogenes (Bacillus Coagulens).  This is one of the best tolerated probiotics – it is the least likely to cause bloating or discomfort.  It is shelf stable, so no refrigeration required, and it can get past the harsh stomach acid to get to work in the large intestine where it should be.
