Vitamin D is important for strong bones Vitamin D regulates the amount of calcium that your body can absorb from the intestines into the bloodstream. Low vitamin D levels can increase your risk of osteoporosis and broken bones. Women are at a higher risk in menopause as a result of lower levels of the bone-building hormone estrogen, in combination with deficiencies of important vitamins and minerals. People who have anorexia are also at high risk because they tend to have nutritional deficiency, including a lack of vitamin D, and low levels of estrogen. Lifestyle factors such as smoking, stress and physical activity are also risk factors. Do you need to supplement vitamin D if you spend a lot of time in the sun? The World Health Organization reports that nearly 1 billion people have a vitamin D deficiency, especially in regions with consistent cloud cover. When sunlight (UV radiation) hits us, our body's cholesterol converts to vitamin D, specifically the active form, D3. While UV radiation can accelerate skin aging and raise skin cancer risks, our skin needs it to produce active vitamin D. The amount of radiation you receive, and the subsequent vitamin D your skin produces, depends on your skin's surface area exposed, your skin color (melanin content), the season, your geographical location, and outdoor time. Darker-skinned individuals often need more sun exposure than those with lighter skin to produce the same vitamin D levels. Vitamin D deficiency is common A normal level of vitamin D is important for cell production 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 and skeletal breakdown as well as 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 vulnerable 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. Dietary sources are mainly fatty fish (such as salmon and mackerel), dairy products, egg yolks and other animal foods. 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 having a vitamin D deficiency. Vitamin D deficiency symptoms Vitamin D deficiency manifests itself with many nonspecific symptoms: Fatigue / exhaustion Bad mood Sleep disorders Pain in the head and neck Muscle weakness Increased susceptibility to infections How does the Vitamin D Test work? The Vitamin D test is a test performed from the blood (serum). After you have placed your order, we will send you a test kit that contains everything you need to be able to take the blood test at home. It is a capillary blood test, which means that you do it via a prick in your finger. Your sample is then sent to our lab for analysis and you receive the test result digitally. Quick, easy and simple!
