What are D-Pearls?
D-Pearls are small, soft gelatin capsules with 25 μg (1000 International Units) of vitamin D3 in each capsule. The vitamin D is dissolved in high quality cold-pressed olive oil to improve absorption in the digestive system as vitamin-D is a fat-soluble vitamin. The capsule size makes them easy to swallow, but they can also be chewed. Research has shown that D-Pearls have a high absorption in the body.
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 D-Pearls is control analyzed.
D-Pearls has been on the European market since 2007.
Pharma Nord's D-Pearls has been tested by researchers at the University of Oslo, where they gave athletes different doses of vitamin D from D-Pearls or inactive placebo capsules. The study showed that vitamin D from D-Pearls both high and low doses was absorbed well by the participants whereas the athletes who received placebo capsules had unchanged levels of 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 (2 x 38 mcg) of vitamin D from D-Pearls daily and the unchanged vitamin D content in the blood of the group receiving placebo capsules .

What is vitamin D?
Vitamin 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. *

Children require relatively more vitamin D than adults.
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 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:
The need for vitamin D
Research has shown that in terms of the amount of vitamin D in the blood, a daily supplement of vitamin D is more effective than larger weekly or monthly supplementations.
Vitamin-D supplements are generally recommended for:
- Children aged 0 – 2 years (vitamin D as drops)
- Pregnant women
- Children and adults with dark skin
- Children and adults who wear fully covering clothes in the summer time
- People who do not spend time outdoors in the daytime or generally avoid sunlight
- Nursing home residents as old people have reduced skin synthesis, and also gut absorption of vitamin D
- People older than 70 years
- Anyone who, regardless of their age, are at increased risk for osteoporosis
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:
> = greater than
< = less than
Vitamin D Conversion
- 1 nmol/l = 0,4 ng/ml
- 25 µg = 1000 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 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.
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.
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 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.
The EU Food Safety Agency (EFSA) has evaluated the evidence behind the product's content of vitamin D and has acknowledged the following statements:
- 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)
Bio-Magnesium: Magnesium has several sites in common with vitamin D: For example, both contribute to the maintenance of normal bones and teeth, a normal muscle function. Also they both play a role in cell division.
