Vitamin D is absorbed into the body primarily through sunlight. Which is all good… As long as the sun is shining. However, in our latitudes this can be all too rare for a permanently adequate supply of Vitamin D. Lifestyle choice can also play a role, for example, “Couch potatoes” or people with long working office hours are at risk of developing a Vitamin D deficiency. Due to the fact it is difficult to obtain a sufficient amount from food alone.
Although, Vitamin D plays a role in supporting many of the bodies main functions. It contributes to normal blood calcium levels, maintenance of bones and normal muscle function and the maintenance of teeth – amongst other things. One of the most prominent and important functions Vitamin D provides, however, is its contribution to the normal function of the immune system.
But what actually is Vitamin D?
In short, it is the collective term for the group of calciferols, a chemical hormone precursor. So vitamin D promotes the absorption of calcium from food and has a function in cell division.
Vitamin D Daily Requirements
The German Nutrition Society recommends a daily intake 20 micrograms (ug) of vitamin D. Too much vitamin D can be harmful. Therefore, pay attention to the quantity of the nutrient recommendation from the experts at nu3 or on the recommended amount on the product leaflet. Do you have any more questions about Vitamin D?

VitaminD (actually: Vitamin D) is also called the "Sunshine Vitamin". Especially among young people, it is possible to have enough sunshine on the skin of the hands, arms and face in around quarter of an hour to supply the body with the required daily amount of Vitamin D.
The Problem: In order to produce Vitamin D in this way, the sunlight in our latitudes is often too weak. From the age of 30 the bodies ability to produce Vitamin D by UV rays has changed. Especially during the cold season, when "couch potatoes" and the elderly are at risk of Vitamin D deficiency.
The Vitamin – especially Vitamin D 3 with it‘s very high bioavailability – has more that one role in the nutrient supply oft he body: VitaminD…
contributes to normal blood calcium levels,
contributes to the normal maintenance of teeth and
contributes to the normal muscle function and immune system function.
In addition, VitaminD has a function in cell division.
Nutritional supplements can make an important contribution ensuring the body continuously and reliably receives the recommended daily amount of 20 micrograms (ug) of Vitamin D. They are available in capsule form as mono-preparations that contain only Vitamin D, as well as combination preparations with other vital substances. Also specifically for vegans, there are dietary supplements containing Vitamin D.
Vitamin D3 supplements can obtained as a single agent supplement or as part of a combination product which include other vitamins and minerals. Many products in this range are suitable for the lactose and gluten intolerant and are free from artificial preservatives, flavours and colours. This essential vitamin is available in both tablet and capsule form and includes only pure and natural ingredients.
Vitamin D Without Help From The Sun
The D3 vitamin, sometimes known as cholecalciferol, is naturally obtained when we are exposed to sunlight and when we consume particular foods such as liver, oily fish and other animal products. In the long term however, dietary intake alone many not be adequate to maintain optimal levels, especially in areas with less sun. Vegetarians and vegans may also be at a greater risk of D3 deficiency as they do not consume foods containing this vitamin as a normal part of their diet. In the absence of sunlight, or when sunlight is scarce, the recommended levels of D3 may also be further reduced. As we age, and at a time when we are at increased risk of brittle bones and other Musculoskeletal disorders, our ability to naturally produce D3 declines, which may further contribute to a deficiency of this vitamin. Similarly, D3 deficiency during pregnancy is also not uncommon.
This essential nutrient contributes to the maintenance of bones and teeth, as well as normal muscle function. Another important function that Vitamin D provides, is its contribution to the normal function of the immune system, reducing the risk of infections. The recommended daily intake of Vitamin D3, for adults, is 20mcg per day in order to maintain a strong Musculoskeletal system.
Vitamin D supplements
Vitamin D supplements help to provide your body with an adequate and balanced supply of nutrients. This vitamin is present in very few food sources so when there are low levels of sunlight. When the sunlight touches the skin, vitamin D synthesis occurs. The further away from the equator people live, the more exposure to sunlight they need. People with dark skin pigmentation need more sun in comparison to those with lighter complexions. Supplements can assist in keeping levels topped up, when too little sunlight is received, or diet is insufficient.
When are Vitamin D supplements required?
Vitamin D contributes to normal blood calcium levels, as calcium cannot be absorbed as efficiently, when vitamin D supplies are deficient. Vitamin D and calcium both help to prevent the disease osteoporosis. Insufficient levels of vitamin D have also been linked to Seasonal Affective Disorder (SAD) and the bone wasting condition rickets. Vitamin D can be found in small amount in foods like oily fish, eggs, powdered milk and fortified cereals.
Suggested daily supplement intake
The supplements we sell, come in the form of capsules and tablets. This makes it easier to keep a track on the daily amounts received. Most of the capsules contain around 25 micrograms of vitamin D, which is equivalent to 1000 IU. This is in fact the average daily requirement for all healthy adults. We also sell vitamin D supplements containing around 62.5 micrograms of vitamin D. Selected capsules contain oil, which delivers lipid soluble vitamin D. Certain products are targeted towards osteoporosis sufferers so be sure to read the labels correctly and consult a doctor if unsure. Vitamin D2 is suitable for vegans, who cannot consume vitamin D3, a type produced from animal by-products. We also have combined supplements available, containing vitamin D and calcium.

Fully Supplying All Your Vitamin D Needs!
Vit. D (vitamin D) is called the sunshine vitamin for good reason. The skin makes vitamin D from cholesterol, whenever there is a clear sky and we are spending time outdoors in the sunlight. Vit. D is also found in certain foods, such as in different varieties of fish. But unfortunately only in very small amounts, which are not sufficient for a complete supply of this vitamin. Which is why our bodies may require vitamin D supplements to avoid a deficiency
Like all vitamins, Vit. D is essential for the body. It not only has a function in cell division, but also contributes to the normal function of muscles. Vit. D also contributes to the normal functioning of the immune system and the preservation of normal teeth and bones in both adults and children.
The problem: in winter, the sunlight is too weak for us to produce the Vit D that our bodies need. Even summer in Central Europe is sometimes not sunny enough to provide us with the sunlight we need to produce sufficient amounts of important vital substances. Therefore, it can be very useful to supply the body with Vitamin D by taking the appropriate dietary supplements -. Especially in the dark season.
In our range of nu3 you will find various Vit.-D products, both as a single preparation, and in combination form (with other nutrients). Each of these products provides the vitamin in the optimal dosage for your daily needs.

Vit. D3 - Calcidiol
Vit. D3 (Vitamin D3) is formed through direct sunlight onto the skin, or absorbed through a persons diet. However, only limited food sources contain an appreciable amount of vitamin D3, for example, very fatty fish, beef or pork liver. As a result the body’s natural synthesizing of Vitamin D3 via sunlight is of high importance.
10 – 15 minutes of sun
If the skin is exposed to around 10 – 15 minutes of sun it can synthesize Vitamin D3 from biochemical 7-dehydrocholesterol, a so-called Sterid that is naturally present in the body. The synthesized vitamin D3 (or, calcidiol – also called cholecalciferol) is then stores as a 25-OH vitamin D in the liver, where it is then in its active form 1,25(OH)2 Vitamin D which is then transferred to the kidney if necessary and converted . This contributes to the normal maintenance of bone as well as to normal calcium levels in the blood.
When the body is burdened by toxic heavy metals, Vitamin D3 activation is inhibited. The vitamin D3 metabolism is at risk of shutting down completely. In this case, the vitamin is still formed in the skin but it does not enter the liver, or the kidneys from there. For an optimal supply of this vital vitamin it can be useful to undergo a proven heavy metal pollution detoxification.
Daily Vitamin D3 Requirements
For the body to by optimally supplied with vitamin D3, a daily amount of 20 micrograms is recommended. The preferred method of intake is obviously naturally through the sunlight. However in our area of the world this is not often possible with long periods without sun. In these cases dietary supplements can make a significant contribution to the sufficuient supply of Vitamin D3 to the body.
