Eggs are a Terrific Source of Vitamin D

The United States Department of Agriculture (USDA), the branch of the U.S. government charged with food oversight, recently released a report claiming that eggs today have 64% more Vitamin D than in 2002, when the USDA last conducted such a study.  The report also stated that eggs in the year 2011 have 14% less cholesterol on average than did eggs sampled in 2002.

Scientists from the agency as well as egg industry representatives are speculating that this change is the result of widespread improvements in the quality of feed given to laying hens over the better part of the past decade.

The findings will undoubtedly enhance the nutritional profile of the incredible, edible egg.  However, it has long been known that eggs are a good source of Vitamin D, and D3 in particular.  In an article dated January of 2009 (over two years ago), nurse practitioner Pamela Egan wrote the following: “Vitamin D is found in many dietary sources such as fish, eggs, fortified milk, and cod liver oil.”  She went on to discuss egg yolks in particular as a high-quality Vitamin D3 food source.

Vitamin D3, also known as cholecalciferol, is the natural form of the vitamin.  It is manufactured by the human body, and the process is fueled by sunlight hitting the skin, but can also be obtained through supplements as well as food sources.  D3 is far more bioavailable (absorbent/usable) than other forms of Vitamin D.

So, for those of you who make a conscious effort to eat healthy and nutritious foods, one of your best sources for Vitamin D just got a lot better.

In spite of the literally thousands of studies from the past four years affirming, confirming and then reaffirming the stark contrast between Vitamins D2 (Ergocalciferol) and D3 (Cholecalciferol) in terms of supplemental value, there is still a great deal of misinformation being fed to the public touting the supposed benefits of Vitamin D2.

Let me be perfectly clear: Vitamin D3 is the form of the D Vitamin that offers unprecedented health benefits to humans whether ingested via food or supplements or absorbed through exposure to sunlight. Vitamin D2 has been under heavy scrutiny the past few years by medical professionals who are informed and up-to-date on the subject, but some apparently either stopped paying attention some time ago or simply choose not to acknowledge the trove of research backing claims of D3′s superiority.

I came across the following over at Revolution Health, a site I otherwise respect:

What is Vitamin D (Ergocalciferol (Vitamin D2)?

Ergocalciferol is vitamin D2. Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.

Ergocalciferol is used to treat hypoparathyroidism (decreased functioning of the parathyroid glands).

Ergocalciferol is also used to treat rickets (softening of the bones caused by vitamin D deficiency) or low levels of phosphate in the blood (hypophosphatemia).

Ergocalciferol may also be used for other purposes not listed in this medication guide.

Given the fact that Revolution Health sells itself as being a credible source for health news and generally backs it up, I was quite surprised when I found out they were among the ill-informed media erroneously talking up Vitamin D2, claiming that D2 supplements provided substantial health benefits.

The reality is that D2 offers few if any benefits to humans. D3 is something of a supervitamin/hormone, but D2 is little more than a synthetic product. It was created for the sole purpose of being sold, as where its counterpart is a completely natural and bioavailable substance that is easily broken down for use by the body.

UPDATE: The list of diseases, illnesses and various other health maladies that have been scientifically linked to Vitamin D Deficiency now stands at 32. The updated version of the list is posted at the bottom of the article.

If you’ve been following the news at all for the past year, you’ve probably read that Vitamin D — Vitamin D3 specifically — helps boost the immune system.  You’ve probably also read that increasing volumes of research seem to indicate a relationship between Vitamin D Deficiency and various diseases.  What you may not have known is just how many different diseases and conditions are now being linked scientifically to deficient levels of this vital nutrient.

Before I go any further, I’d like to clarify the difference between Vitamin D3 and regular Vitamin D. Vitamin D3 (Cholecalciferol) is the form of the vitamin manufactured within the human body from sunlight. It is the most active and bioavailable form of the nutrient, which translated to better absorption within the body. The alternative form of the vitamin is known as D2, or Ergocalciferol.

Over the past several years, the general consensus of experts has been rapidly shifting in the direction of declaring Vitamin D2 a nutrient unfit for supplement form. This is due in part to health experts such as Nurse Practitioner and Health Columnist Pam Egan, who dared to challenge the conventional wisdom regarding Vitamin D at a time when the term “Vitamin D3″ was largely unheard of. Mrs. Egan has been distinguishing between the two forms of the vitamin in her published writings for most of the past decade, including a couple of years at the beginning when her peers wrote off her claims as speculative.

While scanning news headlines recently, I was simply awed by the sheer number of stories about the establishment of scientific links between Vitamin D3 Deficiency and disease. In light of this experience, I have assembled a partial list of the seemingly endless diseases and conditions for which the nutritional shortcoming is a contributing factor.

In no particular order, the following is a partial list of some of the diseases and conditions caused in part by Vitamin D Deficiency.

Diseases and Conditions Linked to Vitamin D3 Deficiency:

1. Parkinson’s Disease - Two new studies suggest that older people who are deficient in Vitamin D may be more likely to develop the neurological disorder.  The first study was directed by Paul Knekt of the Finnish Institute for Health and Welfare.  David Llewellyn of Italy’s Exeter University spearheaded the second study, which was published in the Archives of Internal Medicine. Source

2. Asthma - A new study conducted by the Harvard Medical School in Boston found that children low in Vitamin D3 were more likely to suffer an asthma attack requiring hospitalization than were children with healthy levels of the vitamin. Source

3. Chronic Pain - Two studies – one by Dr. Greg Plotnikoff, the other by the Mayo Clinic – appear to show a link between Vitamin D Deficiency and chronic pain. Source

4. Childhood Obesity - A study published in the American Journal of Clinical Nutrition suggests that Vitamin D deficient children are likely to have a higher Body Mass Index (BMI) than their better-nourished schoolmates. Source

5. Osteoporosis in Patients with IBD - A study by the American College of Gastroenterology indicates that Vitamin D deficient patients with IBD (Irritable Bowel Disease) are at a greater risk of developing osteoporosis, osteopenia and an overall higher rate of abnormal bone density. Source

6. Autoimmune Disorders - A study published in Genome Research indicates that people with insufficient Vitamin D are more susceptible to autoimmune diseases such as multiple sclerosis, type 1 diabetes, and Crohn’s disease. Source

7. Arterial Stiffness – The Endocrine Society published a study this past summer linking Vitamin D Deficiency to arterial stiffness in black teens. Source

8. Diabetes and Metabolic Syndrome – Researchers from Johns Hopkins University presented a study at the Endocrine Society’s annual meeting establishing a link between Vitamin D Deficiency and Diabetes and Metabolic Syndrome, which is the medical precursor to diabetes. Source

9. Cancer, Heart Disease and More – The following study appearing in the American Journal of Clinical Nutrition establishes the preventive benefits of Vitamin D3 with regard to various forms of cancer, heart disease and numerous others. Source

10. Rickets – This one has long-been established as fact by the medical and scientific communities, so I therefore feel no need to include specifics or cite sources.  The link has been firmly established and repeatedly confirmed.

11. Inflammation – A 2009 study published in the Archives of Internal Medicine confirmed a link between Vitamin D Deficiency in otherwise healthy women and increased inflammation. Source

12. Autism - There is an increasing body of evidence that Vitamin D Deficiency is a contributing factor to autism. Dr. John Cannell, a psychiatrist and prominent vitamin D advocate, says flagging levels of the vitamin in pregnant women and young children could be the elusive factor explaining the rising rate of autism. Source

13. ADHD - Recent studies from the past several years increasingly point to a relationship between low levels of Vitamin D3 and an aggravation/intensification of the symptoms of ADD and ADHD. Source

14. Influenza & Swine Flu - Research presented by John Cannell, MD of the Vitamin D Council showed that Vitamin D3 is protective against seasonal flu. Further research performed by Norris Glick, MD and Ellie Campbell, DO, showed that Vitamin D3 helps prevent H1N1 Flu. Further, Dr. John Cannell showed that Vitamin D3 deficiency activates the influenza virus (the Flu). Source: Vitamin D3 and Influenza

15. Fibromyalgia - A study published in the Journal of Pakistan Medical Association determined that Vitamin D3 deficiency is frequently seen in patients diagnosed with fibromyalgia and nonspecific musculoskeletal pain. Source

16. Hypertension & High Cholesterol - Evidence from numerous clinical and epidemiological studies have shown that increased dosages of Vitamin D3 can help lower blood pressure and cholesterol in patients deficient in the nutrient. Source

17. Depression - A scientific link between low Vitamin D3 levels and depression has been established following several recent studies confirming the relationship. According to one such study by scientists at Georgia State University: “The likelihood of having depression in persons with vitamin D deficiency is significantly higher compared to those with vitamin D sufficiency. Early diagnosis and intervention are paramount because coexistence of vitamin D deficiency and depression has serious negative consequences on health.” Source

18. Chronic Fatigue Syndrome - Vitamin D deficiency is closely associated with the chronic fatigue in patients with traumatic brain injury. Source

19. Tooth Decay - There is strong evidence indicating a relationship linking Vitamin D Deficiency to cavities and tooth decay. Dozens of studies were conducted in the 1930′s and 1940′s on this very subject. More than 90% of those studies concluded that supplementing children with vitamin D prevents cavities. Source

20. Lung Transplant Rejection - Vitamin D deficiency is associated with a significant increase in lung transplant rejection, according to research conducted at Loyola University Health System (LUHS). Source

Please keep in mind that this is only a partial list of the myriad of diseases and adverse conditions that are either caused in part by or aggravated by Vitamin D Deficiency, or that can largely be prevented with adequate sun exposure and/or supplemental intake.  Check back as I will be posting a follow-up article sometime in the near future listing even more diseases for which this nutritional shortage is a contributing factor.

The BBC reported January 19 on the story of a girl diagnosed with Vitamin D Deficiency, which has been linked to the bone disease Rickets. The girl’s doctor told her that an SPF 50 sunscreen may be the culprit.

By blocking out the sun, the cream interfered with the body’s ability to absorb the sunlight and use it to manufacture Cholecalciferol, better known as Vitamin D3. By using the sunscreen on a regular basis, the girl was routinely depriving herself of the nutrient, which eventually resulted in a full-blown deficiency.

Vitamin D3 helps the body absorb calcium, reduce inflammation, boost the immune system, protect against rickets, and some relatively new studies suggest it may even help with hormone regulation. There also appears to be a growing body of evidence suggesting that Vitamin D may even help stave off some forms of cancer.

The video from the BBC report is below.

The American Academy of Dermatology (AAD) has come under fire for a recent statement issued on behalf of the organization claiming that sun exposure is not necessary in order for a person to obtain sufficient amounts of vitamin d3 (cholecalciferol).

A group known as The Vitamin D Council blasted the dermatologists association in response to the statement, claiming the statement was an attempt to protect the Academy from potential liabilities stemming from previous campaigns to increase sunscreen use, which the Council claims resulted in mass-vitamin d deficiencies.

In response to the outpouring of criticism stemming from its earlier statement, the AAD released a revised statement in which the semantics appear to have been tinkered with but little actually changed substantively speaking.  Though the wording was slightly different, the group stood by its claim that people should obtain vitamin d through food and not via the sun. The reason, they claim, is that the costs in terms of damage to the skin outweigh the benefits brought about by the vitamin d3.

Who Should Take Vitamin D Supplements, How Much and Why?

Vitamin D supplements, particularly those providing the more bio-available form known as Vitamin D3 or cholecalciferol, can be of life-saving importance to a larger percentage of the population than most would probably assume. Of all the vitamin and mineral supplements out on the market, Vitamin D3 supplements may be the most under-consumed and most important among them.

According to a number of recent studies, between 50-80% of the American population isn’t getting enough Vitamin D. This number is believed to be even higher among African Americans. Part of the problem is that a disturbingly high number of people either aren’t aware of the importance of healthy levels of the nutrient or make the mistake of assuming they get enough by way of diet and/or sunlight.

Remedial Information about Vitamin D is Misleading

While most of us learned in school about the ever-important D vitamin is technically true (that Vitamin D is obtained via sunlight naturally), it is woefully incomplete information that has contributed to the crisis many health experts describe as a Vitamin D deficiency epidemic. We get Vitamin D from the sunshine. It is a “nonessential” vitamin (although that term is very misleading). What this effectively means is that our bodies can make it. Specifically, human skin manufactures it from sunshine, the liver breaks it down, and finally the kidney activates it into a form that is thousands of times more potent. This job provided by the kidney is lost very in the early stages of chronic kidney disease, and diminishes substantially often simply as a result of the aging process. What’s more, older people’s skin is not able to optimally manufacture the nutrient from sunlight.
So what does this all mean to the average American who likely had never so much as considered whether or not he or she was obtaining sufficient amounts of the nutrient?

Most of us also learned in school that inadequate Vitamin D levels can lead to rickets. But how many adults actually know someone with rickets? This is precisely the dilemma — rickets is not a disease people are used to seeing and thus, intricately familiar with.

Think You’re Getting Enough Vitamin D?  Think Again

Far too many Americans are of the mistaken belief that they are getting enough sunshine, and what they’re not getting in terms of sun is compensated for by diet. This is a big mistake, at least if the studies indicating that more than half the American population is deficient are correct. Paying a (probably already overdue) visit to the doctor and having one’s Vitamin D levels checked takes very little time and is a relatively inexpensive test. This test is the only way to know for sure if one is low in the nutrient and thus susceptible to the assortment of health ailments and illnesses associated with the condition.

More Milk isn’t the Answer

Milk is fortified with Vitamin D, and many who are cognizant of the importance of the vitamin assume that drinking milk will help stave off deficiency. Technically this isn’t completely inaccurate. There’s just one problem with that line of thinking though: it would take approximately 16 glasses of milk a day to provide the necessary amount of Vitamin D needed to stave of deficiency and deficiency-related illness. What’s more, the Vitamin D found in milk breaks down when exposed to light? Most major grocery chains store milk under fluorescent lights 24-7 until it sells. Even if the milk is stored in such a way as to protect the nutrients inside it, sixteen glasses is a lot of milk — even if you like milk.

Rickets we rarely encounter, sunshine we have aplenty, and we’ve survived this long without nutrient-rich milk, so what does it matter? The human body requires Vitamin D for many internal processes. It is a co-factor in myriad activities within the body. Most of us did not learn this in school as scientists only recently discovered just how critically important this nutrient is.

Vitamin D Deficiency Epidemic

What you don’t know, can hurt you. Without enough Vitamin D, not only are we vulnerable to rickets, but more importantly processes begin in which the body essentially turns itself into bone. Genes get *up-regulated(1) in the absence of needed levels of Vitamin D, which lead to the building of bone matrix in soft tissue. That tissue includes blood vessels, the heart, liver, pancreas, the list goes on. Upon that matrix, minerals like calcium are laid down and turn it into bone. This obviously is not good for one’s health. As a matter of fact, this directly correlates with mortality rates — especially via heart disease.

The lower the Vitamin D levels, the higher the mortality rate! Vitamin D deficiency has now been linked to colon cancer, diabetes, hypertension, fibromyalgia, proximal muscle weakness, and many, many others. While the death certificate doesn’t typically list Vitamin D deficiency as the cause-of-death, an alarmingly high number of debilitating and potentially even fatal diseases and illnesses have been associated with deficiencies in Vitamin D levels. So which came first, the chicken or the egg?

Vitamin D deficiency is indeed an epidemic. In numerous studies, 50-80% of the American populations studied are deficient in this Vitamin. These numbers are believed to be even higher among African Americans. While rickets is not regarded as a serious health concern, more and more people are diagnosed with heart disease, hypertension, and diabetes everyday in every family. Can anything help to prevent this?

More Sunlight Not Necessarily the Answer

The sun has gotten a bad rap. We know it causes aging of our skin and skin cancer. This is true, and in the case of skin cancer potentially deadly, so getting more sunlight is not necessarily the answer. Worth noting is the fact that the darker one’s skin, the less Vitamin D that person is able to manufacture all other things being equal. This likely explains why African Americans are suffering and dying more than any other group from these very same diseases now linked with Vitamin D deficiency.

When one spends considerable time in the sun, what happens? Assuming the person used sunblock, that person will become tan. The darker the skin the less Vitamin D one is able to manufacture, so more sun exposure is not the answer due to it’s catch-22 nature. This is especially true for African Americans and other people with dark skin.

Time in the sun is not a good predictor of one’s Vitamin D level for the reasons stated above. The only way to know if a person is deficient (and about 80% of us are) is to have that person’s Vitamin D levels tested and evaluated. Drinking milk is not going to bring the levels up unless perhaps one maybe owns a cow or has a very large refrigerator to go along with an insatiable appetite. The bottom line is that for most adults, Vitamin D3 supplements are usually necessary to ensure healthy levels and promote good health. According to esteemed Nurse Practitioner and Health Columnist Pamela Egan, “the few patients I see who are not deficient usually have been taking vitamin supplements for years.”

How Much Should I take?

The recommended dosages for Vitamin D are 400 units a day if you are under 50 years old, 600 units a day for those 51-70, and 800 units a day for those over 71. When one is deficient, it is very difficult to replete levels with over the counter doses of Vitamin D. A prescription-strength dose is often required, and can be beneficial with a weekly dose.

Nurse Practitioner Egan offered the following piece of advice for readers of this blog: “Talk to your doctor, get a level measured, and supplement your deficiency with enough D to maintain adequate levels. Let’s all live a long and happy life!”

Research shows it is possible to drastically reduce the risk of Seasonal Flu and Swine Flu by supplementing regularly with Vitamin D3.

There has been a fear of a pandemic flu outbreak for the past several years. My own parish received 20,000 body bags last year in preparation for the flu pandemic. Research presented by John Cannell, MD of the Vitamin D Council showed that Vitamin D3 is protective against seasonal flu. Further research performed by Norris Glick, MD and Ellie Campbell, DO, showed that Vitamin D3 helps prevent H1N1 Flu. Further, Dr. John Cannell showed that Vitamin D3 deficiency activates the influenza virus (the Flu).

Currently, the U.S. Recommended Daily Allowance for Vitamin D3 is 400 iu/day. This dose was recommended to prevent rickets, which works well, but does nothing to give the far more important protection from cancer, heart disease and infections. Approximately 70% children in the US and 75% teens and adults have a Vitamin D3 deficiency. We now have overwhelming evidence that therapeutic levels of this miracle vitamin, not only boost our immune system, but protects us from cancer, including breast cancer and even H1N1 Swine Flu. Blood levels of D3 (OH-25) should be at least above 50, optimally 80. Most children and adults can be maintained on vitamin D3 5000iu – 10,000iu/day. At the first sign of flu or respiratory illness, take 50,000iu D3/day x 5 days.

Vitamin D3 Deficiency Can Be Prevented Through Sunlight, Food Sources

Vitamin D is found in many dietary sources such as fish, eggs, fortified milk, and cod liver oil. The sun also contributes significantly to the daily production of Vitamin D3, which is also known as Cholecalciferol.

Trying to incorporate more Vitamin D3 through your diet can easily be done. Cholecalciferol is created through exposure of your skin to the sun, but due to many being wary of overexposure to the sunshine, some can have deficiencies. Through 15 to 20 minutes of sun exposure daily, the body creates 10,000 to 15,000 IUs of Vitamin D3.

Vitamin D3 Deficiency can lead to obesity, high blood pressure, depression and psoriasis. Luckily, there are a few other sources of Vitamin D3 including some foods that can supply sufficient quantities of the nutrient for those who cannot sunbathe for whatever reason. If you are staying out of the sun, consider the following foods to keep your body healthy:

Cod Liver Oil

1. According to drweil.com, Dr Weil states the National Institutes of Health finds cod liver oil can provide up to 1,300 IU of Vitamin D per tablespoon, which is more than the 1,000 IU daily recommendation. They also find cod liver oil to be a good source of Vitamin A. Fish oil supplements are available in liquid capsules and in oil form. Taking cod liver oil daily can help your body get the Vitamin D3 it needs.

Fortified Foods

2. Pamela Egan, FNP-C, CDE, suggests eating fortified foods such as milk and cereal to make up for Vitamin D3 Deficiency. By checking labels on fortified milks and cereals, one can select items that will provide sufficient amounts of this critical nutrient to help stave off deficiency. By starting the day with a bowl of fortified milk and cereal, your body can get a full day’s serving of D3.

Egg Yolks

3. Another great source of Cholecalciferol is egg yolks. Making an omelet or scrambling a couple eggs can give you almost a full daily serving. Studies conducted by the Agricultural Research Centre of Finland published in the Journal of Agricultural and Food Chemistry find feeding chickens a feed high in Vitamin D produces eggs that are sevenfold higher in Vitamin D3 than normal eggs. In the future, one egg might solve the complex and extremely serious health problem that is Vitamin D3 deficiency.

Vitamin D3 is manufactured by the body when human skin is exposed to direct sunlight. It can also be obtained through certain foods, as well as supplements. The main difference is in D3′s superior bio-availability, which lends to better absorption of the nutrient and enhanced health benefits directly associated with absorption factor and the fact that Vitamin D3 is a more naturally occurring form of the nutrient.

According to Nurse Practitioner Pam Egan, Vitamin D3 is “not to be confused with inactive Vitamin D2.”

Two Major Types of Vitamin D

Although there are a total of five different forms of Vitamin D, only two are commonly used in supplements.

1. Ergocalciferol (Vitamin D2) - A synthetic form of Vitamin D. This is the form found in most nutritional supplements. D2 is substantially less bioavailable than D3.
2. Cholecalciferol (Vitamin D3) – The naturally occurring form of the D Vitamin. This is the same Vitamin D manufactured by the human body when skin makes contact with direct sunlight. Cholecalciferol is five-times (or 500%) more bioavailable than Ergocalciferol, which means that D3 is converted into a usable form by the body at a rate five times faster than is the case with D2.

Another drawback with Vitamin D2 is that it has a much shorter shelflife than does D3, and its metabolites do not bind well with proteins, rendering it that much less effective than the alternative.

Many recent studies have suggested that Vitamin D2 should no longer be classified as a nutrient appropriate for supplementation and/or fortification in foods. Despite this, it continues to be the most common form of Vitamin D available in supplement form on the market today.

In conclusion, based on all of that documented above, it is clear that Vitamin D3 is a far superior form of Vitamin D than is D2, and anyone who takes their health seriously should strongly consider double-checking to make sure they’re getting the good stuff (Cholecalciferol) as opposed to the inferior Ergocalciferol when shopping for Vitamin D supplements.

Cholecalciferol (aka: Vitamin D3)

Pam Egan, FNP-C, CDE, is a board-certified adult and family nurse practitioner, a certified diabetes educator, certified specialist in anti-aging medicine, and also a health columnist. Mrs. Egan has written extensively on the subject of Vitamin D3 and the wealth of both short and long-term health benefits associated with this incredible vitamin.

Vitamin D3, also known as cholecalciferol, is by far and without question the most bio-available form of Vitamin D.

Why is Vitamin D3 so important?

Vitamin D is essential for healthy-looking skin and strong bones. In addition, Vitamin D3 has been found to stimulate the immune system, providing your body with a powerful boost to help stave off illness.

If an individual has chronically low Vitamin D3 intake from food and/or sunlight, the deficiency can lead to numerous health ailments including Chronic Fatigue Syndrome, Obesity, Diabetes, Cancer, Fibromyalgia, neuro-degenerative diseases, osteoporosis, and clinical depression. Scientists and researchers are now discovering that the risk of heart disease, heart attack and stroke may increase in people with a prolongued Vitamin D3 deficiency.

D3 can be obtained from a variety of foods, however perhaps the best way to ingest/absorb the nutrient is through sunlight making direct contact with skin. A handful of top health and nutrition experts have even recommended sunbathing in the nude for ten to fifteen minutes daily as a means of ingesting/manyfacturing sufficient amounts of this critically important vitamin in its most potent and bioavailable form.

In addition to foods and sunlight, perhaps the easiest way to ingest sufficient amounts of D3 is via supplementation. A number of high-quality Vitamin D3 Supplements exist to help one ingest enough of the nutrient on a regular basis, including when weather prohibits one from sunbathing.

Included are some links at the bottom of this post to some additional educational resources about Vitamin D3, authored by Nurse Practitioner Egan.
