What is Bio-Vitamin D3, 75 µg?

Bio-Vitamin D3 (D-Pearls) are small, soft gelatin capsules with 3000 IU (75 µg) vitamin D3 in each capsule. The vitamin D is dissolved in cold-pressed olive oil to improve absorption in the digestive system as vitamin-D is a fat-soluble vitamin. Their size makes them easy to swallow, but they can also be chewed. Research has shown that Bio-Vitamin D3 have a high absorption in the body.

Safety

You can be absolutely sure that each capsule contains the amount of vitamin D indicated on the preparation, as each and every batch, ie. each new production of Bio-Vitamin D3 is control analyzed.

The small gelatin capsules can naturally vary in their firmness in step with fluctuations in air temperature and humidity. It has absolutely no bearing on the quality and effect of the capsules as we have tested this in our climate cabinets.

Bio-Vitamin D3 has been on the European market since 2007.

Documented bioavailability

Graph showing good bioavailability of D-pearls

D-Pearls have been tested by researchers at the University of Oslo who gave athletes different doses of vitamin D in the form of D-Pearls and inactive placebo capsules. The test showed that D-Pearls both in high and low dosage was absorbed well by the participants while the athletes who received placebo, had unchanged vitamin D in the blood.

The illustration shows the difference in vitamin D in the blood during 4 weeks in the group receiving 76 mcg of vitamin D daily and in the group receiving placebo capsules.

What is vitamin D?

Elderly smiling manVitamin D is a fat-soluble vitamin. This implies that the vitamin need some fat in order to be absorbed in the intestine. Like other vitamins, vitamin D is essential. There are several kinds of vitamin-D, but the two most important forms are D2 (ergocalciferol) and D3 (cholecalciferol). D3 is the form of the vitamin that is synthesized in the skin when we are exposed to sufficient amounts of sunlight or a similar type of UV-radiation. Vitamin D from sunlight is an effective vitamin D source but is only produced when the sun is high in the sky. In large parts of Europe, this only happens during the summer period, and therefore we can only produce sufficient levels of the vitamin this time of year.

Vitamin D2 Is only available from the diet. It is produced by certain fungi and plants when they are exposed to ultraviolet light. Both vitamin D2 and D3 require subsequent activation in the liver and kidneys in order to become biologically active. Science used to believe that both forms of vitamin D were equally effective in the body. However, depending on the measuring method used, vitamin D3 is 56-87 per cent more effective than vitamin D2 when it comes to raising blood levels of vitamin D. Moreover, D3 is stored in fat tissue more than three times as effectively as D2. *

Vitamin D has an array of important functions in the body. For instance, vitamin D is:

  •  important for normal cell division
  •  helping to maintain normal bones and teeth
  •  contributing to a normal absorption and utilization of calcium and phosphorus
  •  playing a role in the body's immune system and muscle function


Good vitamin D sources

Vitamin D is hardly found in plant foods, it is low in dairy products and found in highest amounts in some animal foods. Some of the best sources being:

Sources of Vitamin D

There are two primary sources of vitamin D: Sunlight and Diet.

Vitamin D from the Sun

We form a precursor to vitamin D3 in the skin based on cholesterol when we get enough sunlight or equivalent UV radiation. This precursor must subsequently be converted (hydroxylated) in the liver and kidneys, respectively, to become active vitamin D.

Vitamin D from sunlight is an effective vitamin D source but is only produced when the sun is high in the sky. In large parts of Europe, this only happens during the summer period, and therefore we can only produce sufficient levels of the vitamin this time of year.

Rule of thumb

To form vitamin D from sunlight, the UV index must be at least 3 or higher. The UV index is used as a measure of the intensity of the Sun's ultraviolet radiation. If you are in doubt about whether you can form vitamin D from the Sun, look at your shadow. If the length of your shadow has the same or shorter length than your height, then you can form vitamin D. If, on the other hand, the shade is longer than the height, vitamin D is not formed.

Vitamin D from the diet

Vitamin D is found only in larger amounts in oily fish, such as salmon, herring and mackerel. Additionally occurring vitamin D are found in limited quantities in meat, dairy products and eggs. In the plant kingdom vitamin D is available only in small amounts in certain fungi. In our diet some of the best sources of vitamin D are:

  •     Cod liver

  •     Oily fish

  •     Oils
  •     Egg yolks
  •    Butter
  •    Fungi


There is some loss of vitamin D from the diet when heated.

   
     

The need for vitamin D

Strong vitamin-D supplements might be particularly indicated in:
 

  • Graph showing the skins decreasing ability to produce vitamin D with increasing ageIndividuals with dark pigmentation as they require 5 to 10 times more exposure to sunlight to generate same amounts of vitamin D3 as individuals with little or no pigmentation
  • Anyone who, regardless of their age, are at increased risk for osteoporosis
  • People who do not spend time outdoors in the daytime or generally avoid sunlight
  • Adults who wear fully covering clothes in the summer time
  • Nursing home residents
  • People older than 70 years. An older skin is less able to generate vitamin D3 from sunlight


Vegans and vegetarians are advised to adhere to the official guidelines for sun exposure and possibly take a supplement of vitamin D during the winter period.
Blood levels of vitamin D can be determined by a blood test that measures the unit 25-hydroxyvitamin D (25-(OH)D) and is expressed in nmol/l. Vitamin D status is graduated in the following way:

Unit: nmol/l Unit: ng/ml
  • <12 nmol/l: Severe deficiency
  • 12-25 nmol/l: Deficiency
  • 25-50 nmol/l: Insufficient
  • >50 nmol/l: Sufficient
  • 75-150 nmol/l: Optimal level in individuals with fragile bones and kidney patients
  • >approx. 200 nmol/l: Risk of overdose
  • <5 ng/ml: Severe deficiency
  • 5-10 ng/ml: Deficiency
  • 10-20 ng/ml: Insufficient
  • >20 ng/ml: Sufficient
  • 30-60 ng/ml: Optimal level in individuals with fragile bones and kidney patients
  • >approx. 80 ng/ml: Risk of overdose

> = greater than
< = less than


Vitamin D Conversion
 

  • 1 nmol/l = 0,4 ng/ml
  • 75 µg = 3000 IU (international units)


Measurement of vitamin D

The safest way to know one's vitamin D status is by means of a blood test. However, for normal, healthy individuals there is no immediate need to measure blood levels of vitamin D. For certain groups, however, it is advisable to gauge their vitamin D status.

For instance, people with a lifestyle that gives reason to believe that they could benefit from checking their status. Besides the obvious factors that limit vitamin D such as lack of sunlight and poor diet, there are more subtle causes such as the fact that some types of medicine may affect the body’s vitamin D absorption, thereby increasing the need for this particular nutrient.

Vitamin D and the normal aging process

Although the aging process affects us differently depending on our genome and lifestyle, everyone will find that, over time, the body becomes worn out and functions less efficiently. This phenomenon is part of the normal aging process and can also have an effect on the amount of vitamin D we need.

Most of the body's cells are equipped with vitamin D receptors, which are small structures on the cells’ surface that are activated by active vitamin D3. These receptors on the different cells is also the explanation for the many different effects of vitamin D in the body.

  • The immune systemThe immune system

It became clear that vitamin D contributes to the normal functioning of the immune system when it was discovered that various white blood cells such as macrophages and dendritic cells as well as T and B lymphocytes are equipped with vitamin D receptors. Vitamin D is necessary for these immune cells to perform their functions. For example, it has been shown that active vitamin D activates genes in the cell nucleus; these genes encode peptides that inhibit viruses, bacteria and fungi.

Our immune system reaches peak efficiency in the teenage years. Even in healthy elderly people, the immune system has become more vulnerable to new infections that it has not encountered before. The elderly, for example, have fewer white blood cells in the blood, and the degree of inflammation in the body is higher than in younger people. Older people should pay special attention to getting enough vitamin D.

  • Bone tissueThe bone tissue

Our bone mass peaks at the age of 20 - 30 years. After this, the bone tissue slowly becomes lighter and more porous. Vitamin D is necessary for normal bones and teeth because vitamin D helps us to maintain a normal content of calcium in the blood, and vitamin D is necessary for bones and teeth to absorb calcium.

From the age of 40, there is a gradual loss of bone mass on the order of 0.5% annually for men and about twice as much for women.

  • Muscle functionMuscle function

Our muscles also need vitamin D to function normally. The ability of muscles to contract is dependent on calcium ions. As previously mentioned, vitamin D regulates the blood's content of calcium and in this way also regulates muscle function.

As we get older, the number of vitamin D receptors in muscle tissue decreases. This results in a gradual loss of muscle mass and muscle strength. The heart muscle, on the other hand, is not significantly affected by this.

  • Skin and mucous membranesSkin and mucous membranes

It is known that the body produces a precursor to vitamin D in the skin when exposed to sunlight of a certain intensity, i.e. a wavelength between 290 - 315 nm. Factors that prevent or reduce the production of vitamin D from sunlight are severe air pollution, clothing, dark skin, use of sunscreen, obesity, the sun’s being too low in the sky, and old age.

With increasing age, the amount of collagen and elastin decreases, making the skin flabbier and more wrinkled. The skin becomes less efficient at producing vitamin D from sunlight, and the digestive tract becomes less efficient at absorbing vitamin D.

Official claims

The European Food Safety Authority (EFSA) has evaluated the evidence behind vitamin D and has acknowledged the following claims:

  • Contributes to a normal absorption/utilization of calcium and phosphorus
  • Contributes to normal blood calcium levels
  • Contributes to the maintenance of normal bones
  • Contributes to the maintenance of normal muscle function
  • Contributes to the maintenance of normal teeth
  • Contributes to normal function of the immune system
  • Has a role in the cell division process
  • For men and woman 60 years and older: Vitamin D helps to reduce the risk of falling associated with postural instability and muscle weakness. Falling is a risk factor for bone fractures among men and woman 60 years of age and older. (Art 14a)
