Description
The vitamin D supplement that everyone is talking about - chosen for the groundbreaking 'Coronavit' trial!
The trial which will look at the effects of vitamin D supplementation on the immune system and protecting against Covid-19. This is a huge testament to the quality of our vitamin D supplements. With so many vitamin D supplements to choose from, why choose Pharma Nord?
The trial was also featured on the BBC news! You can see the news report here which also talks about Pharma Nord Bio-Vitamin D:

What are the benefits of vitamin D3?
Vitamin D3 is a fantastic nutrient that's essential for our overall well-being and boasts a number of benefits, including:
-
Contributing to the support of the immune system. What's more, studies have shown that vitamin D may stimulate the body's production of anti-viral and anti-bacterial proteins.
-
Helping to maintain healthy muscles and nerves
-
Contributing to the maintenence of normal teeth and bones
-
Helping our bodies absorb calcium
What is vitamin D3?
Vitamin D3 is a fat-soluble form of vitamin D - when you produce this naturally, it's called cholecalciferol.
We produce vitamin D3 in our skin when exposed to adequate ultraviolet light from the sun. However, our modern lifestyles, which tend to keep us indoors, are depriving us of the sunshine we need. Unfortunately, even the foods we eat rarely contain enough vitamin D3 - if any at all!
Our vitamin D3 supplements are easy to take and specially formulated in gel 'pearls'. Vitamin D3 is liposoluble (dissolves in oil), so an oil-based formula is best. Our preparation is dissolved in cold pressed organic olive oil to enhance absorption. They contain the cholecalciferol form of vitamin D3.
Who might be deficient in vitamin D3?
So, what are the symptoms of a vitamin D deficiency? Fatigue, hair loss, back and muscle pain, and even depression can be symptoms of a lack of vitamin D3. More than one billion people worldwide are estimated to be deficient in vitamin D3. The UK government recommends a vitamin D3 supplement for several key groups of people, including:
-
People over 65 years of age
-
Those with low or no exposure to the sun
-
Pregnant and breastfeeding mothers
-
Young children from six months to five years old
What are D-Pearls 3000 IU?
D-Pearls are small, soft gelatin capsules with 3000 IU (75 µg) of vitamin D3 in each capsule.
The product is designed for invididuals with an increased need for vitamin D. Vitamin D is lipid-soluble so the vitamin D content in D-Pearls is dissolved in cold-pressed olive oil for improved absorption in the digestive system. Due to their small size, the capsules are easy to swallow. According to published research, D-Pearls have good absorption in the body.
Documented bioavailability
Pharma Nord's preparation (D-Pearls) has been tested by researchers at the University of Oslo. In their study, they supplemented athletes with different doses of vitamin D or matching placebo. The study showed excellent absorption of vitamin D from a low- and high-dosed version of D-Pearls. However, the athletes that took the placebo capsules had unchanged vitamin D levels in their blood.
The illustration shows the difference in vitamin D blood levels over a 4-week period in the group receiving 76 mcg (3,040 IU) of vitamin D daily and in the group receiving placebo capsules.

What is vitamin D?
Vitamin D is a lipid-soluble vitamin and needs to be ingested with some kind of dietary fat in order for the intestine to be able to absorb it. Like most 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).
Vitamin D2 Is only available from the diet. It is produced by certain fungi and plants when they are exposed to ultraviolet light.
Science used to believe that both forms of vitamin D were equally effective in the body. However, depending on what method is used to measure their effectiveness, vitamin D3 is 56-87 per cent more effective than vitamin D2 in terms of raising blood levels of vitamin D. Moreover, D3 is stored in fat tissue more than three times as effectively as D2.*

Children and nursing home residents have an increased need for vitamin D
Vitamin D has an array of important functions in the body. For example, vitamin D:
- Is important for normal cell division
- Helps to maintain normal bones and teeth
- Contributes to a normal absorption and utilization of calcium and phosphorus
- Plays a role in the body's immune system and muscle function
Sources of vitamin D
There are two primary sources of vitamin D: Sunlight and Diet.
Vitamin D from the sun
On the surface of our skin we have a cholesterol precursor that is converted into vitamin D when exposed to UV-rays form sunlight. Once it has been exposed to sunlight it is reabsorbed in the body and converted (hydroxylated) in a two-step process, first in the liver and then in the kidneys and in other tissues. Once these two steps are completed, vitamin D has become active.
Sunlight is our main source of vitamin D but the synthesis is only possible when the sun sits sufficiently high in the sky. In large parts of Europe, this is limited to the period from April through September.
Rule of the thumb
To form vitamin D from sunlight, the UV index must be at least 3 or higher. The UV index is used to measure the intensity of the sun's ultraviolet radiation. If you are in doubt about whether you can make vitamin D from the sun, simply look at your shadow to determine the sun's position in the sky. If your shadow on a horizontal surface in the sun is equal in length to your height, then the altitude of the sun above the horizon is 45 degrees. This position enables vitamin D synthesis.
Vitamin D from the diet
It is difficult to get a sufficient amount of vitamin D from the diet alone, partly because one of best sources of the nutrient is oily fish such as salmon, herring, and mackerel, and people generally do not eat all that much fish. Vitamin D is also found in limited amounts in meat, milk, and eggs. In the plant kingdom, vitamin D is available in small amounts in certain fungi. The best dietary sources of vitamin D are:

Cooking, baking, and frying result in a certain loss of vitamin D from foods.
The need for vitamin D
Strong vitamin D supplements might be particularly indicated in:
- Individuals with dark skin pigmentation as they require 5 to 10 times more sun exposure to generate the same amount of vitamin D3 as individuals with little or no pigmentation
- Anyone at increased risk of osteoporosis, regardless of age
- People who do not spend time outdoors in the daytime or generally seek to avoid sunlight
- Adults who wear fully covering clothes in the summer time
- Nursing home residents
- People older than 70 years. Aged 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.
Measuring your vitamin D
The best way to determine your vitamin D status is a blood test. Normal, healthy individuals who eat a balanced diet and are exposed to sunlight generally don't have to worry about their vitamin D status, but certain groups are advised to have their vitamin D levels checked. Science has found that people with dark skin synthesize less vitamin D in their skin that light-skinned people. There is also a relation between low vitamin D status in the blood and overweight and obesity, which is because vitamin D is stored in the body's fat tissue.
Besides obvious vitamin D-limiting factors such as lack of sunlight and unhealthy eating habits, there are more subtle things that can have a negative impact on your vitamin D status. For example, certain types of medicine may impair the body's absorption of vitamin D, thereby increasing the need for the nutrient.
