- Children taking 1,200 IU’s of vitamin D3 per day were shown to be 42 percent less likely to contract influenza, compared to children taking a placebo
- Five Cochrane Database Reviews issued between 2006 and 2010—which are the ‘gold standard’ in terms of medical research reviews—have decimated the popular claim that flu vaccinations are the best and most effective flu prevention strategy available
- The important factor when it comes to vitamin D is your serum level, which should ideally be between 50-70 ng/ml year-round. Sun exposure is the preferred method for optimizing vitamin D levels, as your skin also synthesizes vitamin D3 sulfate, which appears to play an important role in maintaining healthy cholesterol levels and heart health
- Vitamin D supplement dosages have recently been revised based on the latest research data. Most adults need about 8,000 IU’s of vitamin D a day to achieve serum levels above 40 ng/ml, which is still just below the minimum recommended serum level of 50 ng/ml. Children need about 35 IU’s per pound of body weight
By Dr. Mercola
According to the findings from a 2010 study that didn’t get any widespread attention, vitamin D is a highly effective way to avoid influenza.
In fact, children taking low doses of Vitamin D3 were shown to be 42 percent less likely to come down with the flu.
The randomized, double blind, placebo-controlled study included 430 children aged 6-15, who were followed between December 2008 and March 2009.
Half were given 1,200 IU’s of vitamin D3 daily, while the other half received a placebo.
Influenza strains were determined through lab testing of nose and throat swabs.
Eighteen of the children taking vitamin D contracted influenza Type A, compared to 31 children in the placebo group.
Type B influenza rates were unaffected by vitamin D use, however, the illness resulting from Type B influenza strains is typically milder than Type A.
Considering the fact that influenza was reduced by 42 percent at a dose of just 1,200 IU’s a day, it’s possible that even better results might be obtained with higher dosages—depending on just how deficient you are to begin with, of course, because it’s not really the dosage that matters; it’s the amount of vitamin D in your blood.
It’s Not the Dosage that Matters—It’s the Serum Level
Some 40 leading vitamin D experts from around the world currently agree that the most important factor when it comes to vitamin D is your serum level. So you really should be taking whatever dosage required to obtain a therapeutic level of vitamin D in your blood.
At the time GrassrootsHealth performed the studies that resulted in this increased dosage recommendation, the optimal serum level was believed to be between 40 to 60 nanograms per milliliter (ng/ml). Since then, the optimal vitamin D level has been raised to 50-70 ng/ml, and when treating cancer or heart disease, as high as 70-100 ng/ml.
What this means is that even if you do not regularly monitor your vitamin D levels (which you should), your risk of overdosing is going to be fairly slim, even if you take as much as 8,000 IU’s a day. However, the only way to determine your optimal dose is to get your blood tested regularly, and adjust your dosage to maintain that goldilocks’ zone.

The Ideal Way to Optimize Your Vitamin D Levels
While a lot of the focus on vitamin D ends up being about vitamin D supplementation, the IDEAL way to optimize your vitamin D levels is not by taking a pill, but rather allowing your body to do what it was designed to do—create vitamin D from sun exposure.
In a recent interview, Dr. Stephanie Seneff really brought the importance of getting your vitamin D from sun exposure to the fore. While I’ve consistently recommended getting your vitamin D from regular sun exposure whenever possible, her input really convinced me of the wisdom of this natural strategy. She explained that when your skin is exposed to sunshine, it synthesizes not only vitamin D3, but also vitamin D3 sulfate. Your sulfur levels are intricately tied to your cholesterol levels, and plays an important role in the prevention of heart disease.
So essentially, getting regular sun exposure has much greater health ramifications than “just” raising your vitamin D levels and preventing infections. Sun exposure also appears to play a role in heart- and cardiovascular health, and much more!
The sulfated vitamin D formed in your skin in response to sun exposure is water soluble, unlike an oral vitamin D3 supplements, which is unsulfated. The water soluble form can travel freely in your blood stream, whereas the unsulfated form needs LDL (the so-called “bad” cholesterol) as a vehicle of transport. Dr. Seneff’s suspicion is that the oral non-sulfated form of vitamin D may therefore not provide all of the same benefits as the sulfated form, because it cannot be converted to vitamin D sulfate...
If you cannot get your vitamin D requirements from sun exposure, I recommend using a safe tanning bed (one with electronic ballasts rather than magnetic ballasts, to avoid unnecessary exposure to EMF fields). Safe tanning beds also have less of the dangerous UVA than sunlight, while unsafe ones have more UVA than sunlight.
If neither of these are feasible options, then you should take an oral vitamin D3 supplement. It will definitely be better than no vitamin D at all.
Vitamin D Versus Flu Vaccine
Although the featured study did not make any comparison with vaccination, the ‘gold standard’ of scientific analysis, the so-called Cochrane Database Review, has issued no less than five reports between 2006 and 2010, all of which decimate the claim that flu vaccinations are the most effective prevention method available.
For example, just last year, Cochrane published the following bombshell conclusion, which was completely ignored by mainstream media:
“Influenza vaccines have a modest effect in reducing influenza symptoms and working days lost. There is no evidence that they affect complications, such as pneumonia, or transmission.
WARNING: This review includes 15 out of 36 trials funded by industry (four had no funding declaration). An earlier systematic review of 274 influenza vaccine studies published up to 2007 found industry funded studies were published in more prestigious journals and cited more than other studies independently from methodological quality and size. Studies funded from public sources were significantly less likely to report conclusions favorable to the vaccines….” [Emphasis mine.]
So, despite the fact that 15 of the 36 studies included were biased by industry interests, they still couldn’t come up with evidence supporting the conventional claim that flu vaccines are the best and most effective prevention available against the flu.
The Cochrane Database Review has also issued two reports each on the effectiveness of flu vaccines on infants and the elderly, and all four reviews had negative findings!
- A large-scale, systematic review of 51 studies, published in the Cochrane Database of Systematic Reviews in 2006, found no evidence that the flu vaccine is any more effective than a placebo in children under two. The studies involved 260,000 children, age 6 to 23 months.
- Two years, later, in 2008, another Cochrane review again concluded that “little evidence is available” that the flu vaccine is effective for children under the age of two. Even more disturbingly, the authors stated that: “It was surprising to find only one study of inactivated vaccine in children under two years, given current recommendations to vaccinate healthy children from six months old in the USA and Canada. If immunization in children is to be recommended as a public health policy, large-scale studies assessing important outcomes and directly comparing vaccine types are urgently required.”
And for the elderly:
- The available evidence with regards to protecting the elderly is equally abysmal. The authors concluded that: “The available evidence is of poor quality and provides no guidance regarding the safety, efficacy or effectiveness of influenza vaccines for people aged 65 years or older.”
- Cochrane also reviewed whether or not vaccinating health care workers can help protect the elderly patients with whom they work. In conclusion, the authors state that: “[T]here is no evidence that vaccinating health care workers prevents influenza in elderly residents in long-term care facilities.
Is Influenza a Symptom of Vitamin D Deficiency?
Getting back to vitamin D, Dr. John Cannell, founder of the Vitamin D Council, was one of the first to introduce the idea that vitamin D deficiency may actually be an underlyingcause of influenza, which would help explain its apparent benefits as a flu-fighter. His hypothesis was published in the journal Epidemiology and Infection in 2006, which was followed up with another study published in the Virology Journal in 2008.
Dr. Cannell’s hypothesis received further support and confirmation when, in the following year, the largest and most nationally representative study of its kind to date discovered that people with the lowest blood vitamin D levels reported having significantly more recent colds or cases of the flu.
In conclusion, lead author Dr. Adit Ginde stated:
“The findings of our study support an important role for vitamin D in prevention of common respiratory infections, such as colds and the flu. Individuals with common lung diseases, such as asthma or emphysema, may be particularly susceptible to respiratory infections from vitamin D deficiency.”
The evidence supporting Dr. Cannell’s hypothesis of influenza as a symptom of vitamin D deficiency is so compelling that I, for one, believe optimizing your vitamin D levels is one of the absolute best flu-prevention strategies available to date. But that’s not to say it’s the only factor. Your overall immune function cannot be ignored, and when it comes to maintaining optimal immune function, your diet becomes sacrosanct.
