We get vitamin D through the skin when exposed to the sun and through the diet. Vitamin D is important for our well-being, lack of vitamin D can cause symptoms such as depression, muscle weakness and soreness. According to the Nordic nutritional recommendations, there is probable evidence that vitamin D reduces the risk of developing cardiovascular disease, colorectal cancer and breast cancer. It is important to find out what vitamin D level you have as too high levels of vitamin D can cause hypercalcemia (increased level of calcium in the blood) and can after a long time result in calcification of soft tissue and cause damage to among other things kidneys, blood vessels, heart and lungs.
Here's how it works: The test is a blood test and is taken through a capillary sample (stick in the finger). The amount is two filled tubes.
Test answer: You normally have an answer within 15 working days after our lab received your test. The test answer is sent digitally to your e-mail. Together with your test answer, you will receive a detailed report in Swedish about your values.
Vitamin D is important for a variety of functions in the body such as the immune system, insulin function, nerve function, heart muscle function, bone structure and much more. Vitamin D is a steroid hormone and can be met to some extent from the diet but can also be formed in the body with the help of sunlight. If you have a low level of vitamin D, you need to supplement your diet with Vitamin D.
Vitamin D regulates calcium uptake from the intestine into the bloodstream. Too little vitamin D leads to the skeleton being leached out of calcium, which in turn leads to osteoporosis. A large risk group for osteoporosis is women in menopause because the formation of the bone-building hormone estrogen then stops, in combination with deficiencies of important vitamins and minerals. Anorexics are also at high risk because this target group often has a nutritional deficiency, including a lack of vitamin D, and has a low level of estrogen in the body. Lifestyle factors such as smoking, stress and physical activity are also of great importance.
When we are exposed to sunlight (UV radiation), cholesterol in the body is converted to Vitamin D (D3 as the active form is called). As is well known, UV radiation increases the risk of skin cancer and causes the skin to age faster, but it is this type of radiation that is required for active vitamin D to be formed in the skin.
How much radiation you are exposed to, and thus how much transformation the skin can make, depends on how much skin surface is exposed and what skin color you have. It also depends on the season, geographical residence and how much time you spend outdoors. The wavelength of the sun and the direction of the sun also play a role in the skin's ability to convert the vitamin.
People with darker skin have a poorer ability to form the vitamin than people with lighter skin and therefore need to be exposed to more sun to achieve the same amount of vitamin D from the sun. Older people (who usually stay more indoors) and dark-skinned people living in Sweden are therefore more exposed to the risk of suffering from vitamin D deficiency.
A normal level of vitamin D is important for cell formation in the body and can lead to fewer white blood cells which makes us less resistant and more susceptible to infections. Vitamin D deficiency can also lead to muscle breakdown, skeletal breakdown and high blood pressure. There are also studies that point to a strong link between vitamin D deficiency and cardiovascular disease, depression, and certain forms of cancer.
Particularly prone to vitamin D deficiency are older people who have a reduced ability to produce the vitamin in the body. Older people usually also spend less time in sunlight. Even people with darker skin are at greater risk because they also have a poorer ability to produce vitamin D than people with light skin.
Sources in the diet are mainly fatty fish (such as salmon and mackerel), dairy products, egg yolks and animals. Active vitamin D is not found in vegetables at all, so for those who completely exclude animals and dairy products, the risk is even greater of suffering from a deficiency of the vitamin.
Vitamin D deficiency manifests itself with many nonspecific symptoms:
