Vitamin D – The Sunshine Miracle Vitamin: The Ultimate Vitamin D Benefit and Cure Guide to Beat Diabetes, Lose Weight and Feel Amazing

Vitamin D is an important chemical in the body that helps transport calcium from digested food in the stomach to the blood stream, so it can keep bones strong.

There are two ways the body gets vitamin D,exposure to UV radiation and ingesting foods or supplements that contain vitamin D.

Studies have shown that people who have the lowest vitamin D levels in their blood are at an increased risk of developing diabetes.

The challenge for health care providers and nutrition researchers is to determine whether vitamin D deficiency actually causes or increases the incidence of certain diseases or whether, instead, low levels of vitamin D are simply coincidental given that the majority of the general population, regardless of disease, is likely to have insufficient levels of vitamin D.

In other words, do people who develop diabetes just happen to be deficient in vitamin D, or do low levels of vitamin D cause the disease?

Will supplementation with vitamin D prevent diseases, and can it be used to treat diseases such as diabetes?

In the past, the major source of vitamin D for humans was exposure to sunlight. One possible cause of the current widespread vitamin D deficiency is the lack of sunlight exposure. Another possible cause is a lack of dietary sources of vitamin D.

Since the industrial revolution, very few people get much sun exposure while working.

Other barriers to sunshine exposure include fear of skin cancer, which has led to an increased use of sunscreen, hats, and other sun barriers.

Environmental factors such as pollution and fewer hours of sun exposure during the winter also decrease vitamin D synthesis from sunlight exposure.

Additionally, aging skin and skin of darker color require longer exposure to sunlight to initiate vitamin D synthesis.

There is growing evidence that vitamin D deficiency could be a contributing factor in the development of both Type 1 and Type 2 diabetes.

Evidence indicates that vitamin D treatment improves glucose tolerance and insulin resistance.

Vitamin D deficiency leads to reduced insulin secretion.

Supplementation with vitamin D has been shown to restore insulin secretion in animals.

Furthermore, vitamin D plays an important part in the regulation of calcium.

Calcium helps to control the release of insulin, so alterations in calcium can have a negative effect on beta cell function, which may hinder normal insulin release.

Some scientists and doctors believe that if vitamin D helps proper insulin function, some of its effects might be because of calcium.

Importance of Calcium and Vitamin D




The Calcium Cookbook

Calcium is the most common mineral found in our bones and helps to give them strength and rigidity. Calcium is also particularly important at the time of menopause, because calcium absorption slows down, due to low levels of oestrogen.

A deficiency in Calcium can cause bones to become brittle on the inside and therefore they break very easily. On the outside a person looks perfectly fine. Every cell in our body, including those in the heart, nerves and muscles rely on calcium. Calcium is also necessary for your body to form blood clots.

Who is at risk of low vitamin D levels?

1.   Babies who are just fed breast milk, consume little vitamin D3, especially if the mother is vitamin D3 deficient.

Starter Guide To Baby Food & Nutrition

2. Senior citizen’s: Their ability to produce vitamin D3 in their skin from the sun, is reduced with age and they are less able to convert it into the Vitamin D hormone that the body needs.

3.Those who continuously wear sun block, moisturisers or make up that have sun block in them.

4.People who are obese as body fat has a tendency to hold onto vitamin D, so reducing its overall availability to the rest of the body.

5.Those with darker skin (e.g. Africans) do not absorb vitamin D3 from the sun, as easily as lighter skinned people.

6.Those who have: gastrointestinal disorders such as Coeliac Disease (Gluten/wheat sensitivity); Crohn’s and Ulcerative Colitis; or Primary Biliary cirrhosis and Type1 and Type 2 diabetics.

7. Those, who do not get the recommended daily amounts of Vitamin D3 from the sun or through food sources.

Vitamin D Requirements and Dietary Source

Vitamin D is both a nutrient we eat and a hormone our bodies make. Few foods are naturally rich in vitamin D, so the biggest dietary sources of vitamin D are fortified foods and vitamin supplements.

Good sources include dairy products and breakfast cereals (both of which are fortified with vitamin D), and fatty fish such as salmon and tuna.

For most people, the best way to get enough vitamin D is taking a supplement, but the level in most multivitamins (400 IU) is too low.

Vitamin D and Immune Function

Vitamin D and Immune Function
Vitamin D: Oxidative Stress, Immunity, and Aging (Oxidative Stress and Disease)

Scientists have found that vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin – the killer cells of the immune system — T cells — will not be able to react to and fight off serious infections in the body.

The role of vitamin D in immune system health is not relegated only to T cell activity. Other aspects of immunity might also be affected by vitamin D status.

According to the Linus Pauling Institute, most cells of the immune system, including macrophages and dendritic cells, have a vitamin D receptor on their surface, indicating that these cells also respond to vitamin D.

Under some conditions, macrophages produce their own vitamin D.

In addition, a study published in the June 2011 issue of “Infection and Immunity” found that treating gum cells from the human mouth with vitamin D caused them to produce an antibacterial protein that kills the bacteria that causes tooth decay.

Vitamin D has been used (unknowingly) to treat infections such as tuberculosis before the advent of effective antibiotics.

Tuberculosis patients were sent to sanatoriums where treatment included exposure to sunlight which was thought to directly kill the tuberculosis.

Cod liver oil, a rich source of vitamin D has also been employed as a treatment for tuberculosis as well as for general increased protection from infections.

There is increasing evidence linking vitamin D deficiency and autoimmune diseases including multiple sclerosis (MS), rheumatoid arthritis (RA), diabetes mellitus (DM), inflammatory bowel disease and systemic lupus erythematosus (SLE).

You may find it surprising that vitamin D is so important for your health, especially if you’re still under the impression that it’s mostly a nutrient for your bones.

Most people also think that vitamin D is really a vitamin, but in reality, the active form of vitamin D is one of the most potent hormones in your body, and regulates more genes and bodily functions than any other hormone yet discovered.

Vitamin D is produced as a pro-hormone in your skin after sunlight exposure, and is then converted to the potent hormone form.

Without this hormone, you could die, and indeed, many do die from vitamin D deficiency-related causes.

Vitamin D has a remarkable role to play in your health, influencing nearly 3,000 of your 25,000 genes, and playing a critical role in your immune response — a role far superior to the synthetic (and often harmful) immune responses that vaccines elicit.

Vitamin D could rightly be described as a “miracle nutrient” for your immune system, as it enables your body to produce well over 200 antimicrobial peptides, which are indispensable in fighting off a wide range of infections.

A Japanese study showed that school children taking vitamin D3 supplements were 58 percent less likely to catch influenza A.

That’s a higher effectiveness than any flu vaccine can claim, and doesn’t come with a barrage of potentially devastating side effects!

And there are numerous studies like these, showing the superior effectiveness of natural strategies like vitamin D in the prevention of disease.

Prevention  Of Vitamin D Deficiency


The Vitamin D Cure: 8 Surprising Ways Curing Your Undiagnosed Vitamin D Deficiency Can Revitalize Your Health, Prevent Cancer and Heart Disease, and … Lose Weight: Volume 1 (Vitamin and Minerals)

1. Sun exposure

Sun exposure is the best natural source of vitamin D.  When ultra violet (UV) radiation touches the skin vitamin D is made.  However, a number of things affect this process including age, skin type, where you are in the world and the time of year.

During the summer months  spending a few minutes in the sun is the best way for your body to produce vitamin D.  It is unlikely that your skin will make vitamin D in the winter months.  But, the body can store enough to last between 30 – 60 days.

Because UV exposure is also linked to skin cancer getting a balance between safe sun exposure and vitamin D production is important.

You don’t need to spend hours in the sun to produce enough vitamin D.  Extra time outdoors doesn’t equal more vitamin D, but it does increase skin cancer risk.

The World Health Organisation advice is to get 5 to 15 minutes of casual sun exposure to hands, face and arms two to three times a week during the summer months.

In this way sun exposure as you go about your daily life really makes a difference.


A.Never let your skin redden or burn to get vitamin D

B.Take extra care if you have fair skin because you are more at risk of sunburn

C.Never use a sunbed to increase your vitamin D levels

D.It is important to protect your skin to reduce skin cancer risk.

2. Eating a healthy balanced diet


Vitamin D Diet Benefits: Sunshine, Best Foods, & Disease Prevention

Choosing foods that contain vitamin D is an important part of maintaining a healthy vitamin D level.  The best foods to help with this are:

Cod liver oil

Oily fish such as salmon, herring, mackerel and fresh tuna

Other foods with small amounts of vitamin D include:

Egg yolks


Breakfast cereals that have added vitamin D  – look at the ingredients to check the level

Milk with added vitamin D

Margarines and butter

3. Taking a daily vitamin D supplement

Taking a daily vitamin D supplement is another way to meet your vitamin D needs.

However, it is always a good idea to talk to your doctor before taking a supplement.

It is also recommended that all babies from birth to 12 months are given a vitamin D supplement.

To find out more about this speak with your doctor.

With sun exposure and eating a healthy diet you can get much of the vitamin D your body needs.  But, make sure that you do not increase your risk of skin cancer through over exposure to UV radiation.

If you don’t know your vitamin D levels, or you have never had your vitamin D levels tested, I urge you to consider doing so very soon, as simply assuming your levels are in the healthy range is quite risky. 

Vitamin D deficiency is at epidemic proportions in many regions around the world today, largely because people do not spend enough time in the sun to facilitate this important process of vitamin D production.

Interesting facts, I only knew that vitamin D is involved in the regulation of calcium and phosphorus, but I didn’t know it was so important in diabetes.
So should people suffering from diabetes ask for the advice of a doctor/pharmacist before they start a treatment with vitamin D? Also, do you have any idea if it has the same effect in type 1 diabetes?


    May 9, 2016 at 10:05 am

    Hi Ashley,

    Thanks for taking the time to leave a comment on this post.

    The relationship between Type 1 diabetes and vitamin D is still not fully understood and is still being studied.

    Researchers believe that vitamin D helps make your immune cells act smarter.

    This may be important in autoimmune diseases, like Type 1 diabetes, where your immune cells are mistakenly attacking your own body.

    Researchers are wondering if you get enough vitamin D, if it can help make these cells make less mistakes and help prevent or manage autoimmune diseases better.

    Vitamin D can attach to receptors on your immune cells, and through chemical signals, help direct the cells to communicate and function properly.

    Vitamin D receptors are present in important areas involved with Type 1 diabetes.

    Vitamin D binds to these receptors and helps prevent beta cell death, improve insulin production, and reduce inflammation.

    However, its not clear if these receptors and signals are involved in preventing or treating Type 1 diabetes.

    None of the studies performed so far have found vitamin D to be able to treat Type 1 diabetes, but they do suggest a possible role in helping manage some aspects of the disease.

    These studies suggest that vitamin D plays a role in improving the function of the beta cells, improving insulin production, and managing blood glucose levels, all important things in Type 1 diabetes.

    Vitamin D may have a role in helping the body produce some of its own insulin when alongside standard insulin treatment.

    Research has shown that babies with high vitamin D intake during their first year of life are less likely to develop Type 1 diabetes later in life.

    Research has shown that pregnant mothers with high vitamin D levels during pregnancy are less likely to have children that get Type 1 diabetes later in life.

    So should people suffering from diabetes ask for the advice of a doctor/pharmacist before they start a treatment with vitamin D?

    Whether you are a Type 1 or Type 2 diabetic you should speak with your endicrinologist , dietitian,or doctor who can perform a blood test and advice you on the best vitamin D3 supplement for you.

    When you are a diabetic it is important always to check with your pharmacist or your doctor whether or not any vitamin or herbal product or supplement is safe to take.

    Just because a product is natural does not mean it is always safe.

Hi There
This is a very comprehensive and informative post.I learned so much about Vitamin D and its benefits.In fact, I bookmarked your site as I will want to revisit it, there is definitely some information that I may not have grasped in.

I am a vegan and as you mentioned, the dietary sources of Vitamin D are minimal for people like me.I know you said, get a blood test, but if I just want Vitamin D, as maintenance, would you recommend a. Supplement of 1000 I.u.?

Out of curiosity, what the signs of toxicity of Vitamin D?

Thanks for an awesome article
Take Care

    Hi Roopesh,

    Its great that you found this post interesting.

    If you’re not outdoors a lot and getting plenty of sun, the current recommendations are healthy adults and adolescents especially on a vegan diet should take at least 5,000 IU per day.

    Two months later, have a 25-hydroxy-vitamin D blood test” (to ensure you are in the 30-80 ng/ml range).

    Keep in mind that sunshine can deliver 10,000 to 40,000 IU per day of vitamin D without the risk of side effects.

    If you feel that supplementing with 5,000 IU per day sounds too high being that the vitamin D bottle/package says 1,000 IU per day.

    it would certainly be prudent to take 1,000 per day and see if that amount raises your level into the 30-80 range.

    If it doesn’t, increase to 2,000 a day and test again in two months, etc.

    If you decide to follow the above recommendations of 5,000 per day for adults and adolescents, be sure to test no later than two months after starting supplementation.

    If you get a reading over 80 ng/ml, adjust your vitamin D intake down accordingly and re-test in two months.

    Symptoms of Overdose of Vitamin D

    Typically, initial vitamin D overdose symptoms can include headache, nausea, fatigue, and/or red areas on the face. What follows is a more comprehensive list.

    Early symptoms of overdose (emerge within days or weeks of starting vitamin D supplementation)

    Mild sensitivity in teeth to hot or cold substances
    Wheezing when breathing
    Over-sensitivity to light in the evening
    Bone pain
    Constipation (especially in children or adolescents) *
    Dryness of mouth
    Headache (continuing) *
    Increased thirst
    Increase in frequency of urination, especially at night, or in amount of urine
    Irregular heartbeat *
    Eye twitching
    Itching skin
    Red swollen splotches on the face
    Loss of appetite
    Metallic taste
    Muscle pain *
    Nausea or vomiting (especially in children or adolescents)
    Unusual tiredness or weakness
    * Remember, this could be due to insufficient magnesium .

    Late symptoms of overdose (emerge within weeks or months of starting supplementation)

    Bone pain
    Calcium deposits (hard lumps) in tissues outside of the bone
    Cloudy urine
    Increased sensitivity of eyes to light or irritation of eyes
    Itching of skin
    Loss of appetite
    Loss of sex drive
    Mood or mental changes
    Muscle pain
    Nausea or vomiting
    Protein in the urine
    Redness or discharge of the eye, eyelid, or lining of the eyelid
    Runny nose
    Weight loss

    Late symptoms of severe overdose (emerge after months or years of starting supplementation)

    High blood pressure
    High fever
    Irregular heartbeat

    Stomach pain (severe)

    If you experience any of the above symptoms discontinue Vitamin D supplementation until symptoms disappear,

    Keep in mind that It is not uncommon for side effects to fade slowly over the course of a few weeks.

    A standard protocol in the case of vitamin D overdosing is to not only avoid vitamin D supplements, but also vitamin D fortified foods, sunshine, and calcium supplements for a few weeks, while increasing water intake and physical activity (through vigorous exercise).

    Remember that healthy, natural foods (fruits and green leafy vegetables) contain no vitamin D.

    Also, I’d advise getting an immediate 25-hydroxy-vitamin D test to see just where your levels were when you started experiencing symptoms.

    Besides being good data to have in cases of deficiency and excess, the test is an especially good idea if the symptoms you are experiencing are not actually being caused by vitamin D toxicity.

    You don’t want to be misdiagnosed, which happens more often than you might imagine .

    One last word about over-doing vitamin D supplementation:it may not be that you are getting too much vitamin D, it may be that you are not getting enough magnesium and other “companion nutrients” of vitamin D.

    There are other nutrients that need to be consumed in sufficient quantities for vitamin D to do its job, like zinc, vitamins C, A, and K2, boron, and magnesium.

    Magnesium is the most important of these co-factors where it concerns vitamin D.

    So if you’re experiencing problems when you start supplementing with vitamin D, a magnesium deficiency could be the reason why.

    A vitamin never works alone; it has various relationships with other vitamins in order to work properly.

    And if you’re deficient in magnesium, you could be taking an otherwise “okay” dose of vitamin D but still experience vitamin D deficiency symptoms such as headaches, insomnia, jitteriness, muscle cramps, anxiety, heart palpitations and/or constipation, and your vitamin D level might not improve when taking the vitaminD supplement.

    Those who are eating a healthy diet that contains lots of uncooked fruits,and green leafy vegetables may be getting enough magnesium but those eating a typical Western diet may not (probably not) be getting enough.

    To ensure an adequate supply of magnesium, and the other vitamin D co-factors, a high quality multivitamin may be a good idea if you are not consuming a healthy diet full of green vegetables and fresh fruit.
