What strong vitamin D deficiency symptoms can occur in adults and children? How is the lack of skin, mood and fitness noticeable? How does a test work and what can I do to quickly remedy or prevent a deficiency? These and more questions will be answered by the Trinkkost Ratgeber!

Values ​​- When do You Talk About Vitamin D Deficiency?

Research to date is at odds on how to define vitamin D deficiency levels. Opinions differ as to what percentage of the population actually suffers from a deficiency. According to some endocrinologists, an optimal vitamin D3 level in the blood is more than 30 nanograms (ng) per milliliter. Others also find values ​​of 20 ng per milliliter sufficient. The experts agree that vitamin D levels should not fall below 10 ng per milliliter. According to the German Nutrition Society, however, this is the case in the winter for every fifth person living in Germany. From this value also vitamin D deficiency symptoms appear.

Vitamin D Deficiency Symptoms in Adults

The body needs vitamin D for bone health, the immune system and healthy hair. Vitamin D is also crucial for muscle building alongside other vitamins. Because our organism needs the micronutrient to break down calcium and proteins. Starting at less than 10 nanograms of vitamin D3, symptoms such as lime deposits in the bones, reduced muscle tension, muscle and joint pain, fatigue, moodiness, and sleep disturbances can occur.

Vitamin D deficiency symptoms in adults include hair loss, difficulty concentrating, nervousness, headache, arrhythmia and epilepsy. Other serious illnesses may also be related to low vitamin D levels. These include multiple sclerosis, asthma, cancer, metabolic and autoimmune diseases. The risk of developing dementia is also increased. Obesity is also associated with a shortage. More about this in the Causes section.

Vitamin D Deficiency Symptoms (Adults) at A Glance

A deficiency can be manifested by the following symptoms. However, these symptoms may also indicate other illnesses. A vitamin D deficiency test is therefore essential.

  • Calcium deficiency
  • Lime deposits in the bones, reduced muscle tension, muscle and joint pain
  • Osteoporosis associated with a lack of calcium (especially in the elderly)
  • Tiredness, low moods, sleep disorders, depression, nervousness, difficulty concentrating

Those who have hair loss often think of iron deficiency. Much more often, however, is a vitamin D deficiency in conjunction with a calcium deficiency the cause. Because the body needs vitamin D for the absorption of calcium.

What are Vitamin D Deficiency Symptoms and Consequences in Children?

Consequences of early vitamin D deficiency in infants and toddlers is osteomalacia (rickets). Symptoms of this disease are too soft bones and bone deformities. Among the lifelong consequences of early vitamin D deficiency is the so-called funnel chest. In children and adolescents, inadequate care can also lead to growth disorders.

Vitamin D Deficiency and Skin

Too low vitamin D levels may increase the symptoms of skin disorders. Conversely, a higher vitamin D level can help to keep the skin healthy. As a controlling hormone, vitamin D deficiency symptoms are responsible for the following important processes in the skin:

  • Skin resurfacing
  • Wound healing
  •  Prevention of inflammation / protection against free radicals

Vitamin D can Protect Against Skin Diseases Like

  • Eczema
  • Psoriasis
  • Vitiligo (white spot disease)
  • Lupus erythematosus (butterfly lichen)
  • Acne
  • Skin cancer (however, unprotected sunbathing also increases the risk of skin cancer)

Psoriasis and atopic dermatitis are diseases that are based on a disorder of the skin’s immune system. Although it is not advisable to expose sores to the sun, vitamin D supplements may help prevent and control inflammation. In acne, the treatment success should be particularly large, as vitamin D also regulates the sebaceous glands and hormones. However, the topic of vitamin D deficiency and skin is very complex, as explained in the following article in the Journal of Advanced Research.

How Vitamin D Protects Against Skin Cancer

According to a study by the University of Saarland from 2017, the vitamin D receptors in the body act as so-called tumor suppressors, proteins that prevent uncontrolled cell division. Thus, a low vitamin D level may increase the formation of white skin cancer. According to another study by the University of Houston Cancer Center in 2016, the risk of death from black skin cancer (melanoma) is 1.76-fold higher in patients with severe vitamin D deficiency.

Therefore, if possible vitamin D should be produced as protection during sunbathing. This means: Especially in the summer on regular but short stays in direct sunlight pay attention. But even in winter you should not exaggerate it with the unprotected sunbathing. Although the UV-B rays are less, which cause black skin cancer, but the UV-A rays are the same regardless of the day and the season. And these increase the risk of white skin cancer as well as skin aging.

Vitamin D, Depression And Chronic Fatigue

For a long time, depression has been called the symptoms of vitamin D deficiency. In winter, the vitamin D level drops in many people in our latitudes. However, as sun vitamin is crucial for the formation of the neurotransmitters serotonin and dopamine, low levels of vitamin D may promote depression. At least, it is undisputed that people are more likely to suffer from depression in the winter, and those affected often have a low vitamin D level. Of course, the low scores may also be the result of increased bed-riddenness associated with depression or of general light shortage.

However, an analysis of various studies from 2015 suggests that raising vitamin D levels can reduce the symptoms of depression. The intake of 100,000 IU of vitamin D led to an improvement in symptoms in 74 percent of the affected subjects. In a control group receiving light therapy, the values ​​only improved by 36 percent. People who suffer from chronic fatigue may also have a lack of B vitamins, which can be caused by a vegan or vegetarian diet.

Vitamin D Values ​​Test

With a vitamin D deficiency test, you can find out if your scores are ok. The best way to do this is to go to the family doctor. He uses a blood picture to check the level of 25-OH-vitamin-D3. With so-called self-tests for about 30 euros, a vitamin D test can also be carried out at home. Here you stick with a small prick in your fingertip and take a few drops of blood.

You also send the sample tube included in the test kit to a laboratory. After a few days, you will be notified of your vitamin D levels. However, such a test is not always meaningful. Better let the doctor make a complete blood picture. For a thyroid disease or magnesium deficiency can give unfavorable readings, without a shortage exists.

Causes of Vitamin D Deficiency

The most common cause of vitamin D deficiency is too little direct sunlight on the skin. It should be remembered that the angle of incidence of the sun and the intensity of the radiation also play a role in determining whether sufficient vitamin D is formed. It also matters how much skin surface you expose to the sun.

 In the winter months, it is difficult to correct an existing shortage of sunbathing due to low levels of UV-B radiation in our latitudes. A visit to the tanning salon will only help if the solarium produces UV-B rays. (Many solariums, however, rely mainly on UV-A radiation.) Ideally, the UV-B content of the solarium is at least 2-3 percent. Windows also filter the UVB radiation. So you can not sunbathe in the apartment with the window closed.

Other Causes – Intestinal Disease, Obesity

However, vitamin D deficiency may have other causes. Because some diseases or drugs affect the absorption, utilization or regulation of the vitamin. Then it also comes to vitamin D deficiency symptoms, because the body can not modify the vitamin in its active form. Another possible cause of low vitamin D levels is obesity. Because the organism stores the vitamin in the body fat, so that less active vitamin D is available. In addition, gastrointestinal diseases often lead to insufficient intake.

Vitamin D deficiency causes include:

  • Insufficient sun exposure on the skin (midday sun in summer)
  • Various stomach and intestinal diseases
  • Obesity
  • Kidney disease
  •  Bile or liver disease
  •  Genetic disorders
  • (Side) Hyperthyroidism
  • Granulomatous diseases
  •  Tumors
  • Taking certain medications like antiepileptic drugs
  • Magnesium deficiency

Vitamin D Deficiency Symptoms- Skin And Sun

Daily short sunbaths in summer are ideal for optimal vitamin D levels vitamin D deficiency is the only vitamin that the body can produce by itself through the UV-B rays contained in sunlight. The blood transports the vitamin into the organism. Thus, education requires healthy skin. It is also worth knowing that lighter skin types produce more vitamin D and therefore require less sun. Conversely, darker skin types need more sun to meet their needs. However, this is not a problem because darker skin is less susceptible to skin cancer.

Where is A Lot of Vitamin D in It?

Vitamin D is present only in a few foods in low proportions. As a result, a maximum of 20-30 percent can be covered by food. However, those who do not want to resort to artificial preparations in winter can cover their needs with extracts from certain vitamin D in food. For example, the Trinkkost Vitamin Booster contains the daily requirement of an adult of vitamin B as well as a vitamin B complex. Only with natural ingredients such as mushroom, basil and curry extract. The powder can be simply in the morning in a drink or muesli stir.
To improve low vitamin D levels through the diet is quite hopeless. But at least up to 20 percent of the daily requirement can be covered by a vitamin D-containing food. 100 g of drinking water complete Fruity even contain 1.1 μg of vitamin D3, which corresponds to 22% of the daily requirement.

Vitamin D Preparations Test – When are High-Dose Tablets And Drops Useful?

The Stiftung Warentest recommends risk groups to take vitamin D tablets, drops or capsules. These include babies in their first year and second winter, dark-skinned people, seniors, people with little sun contact or osteoporosis patients. The active ingredient in preparations in tablet and drop form is usually the same: vegetable or animal vitamin D deficiency.

A good preparation recognizes that it contains no additives, but vitamin D from extracts. We recommend taking it with food, for example in the form of a soluble powder that can be stirred into a cup of yogurt. Because the body absorbs micronutrients best in the complex. Vitamins A and D are also fat-soluble.

Vitamin D Dosage and Need

In the table you can see how high the daily vitamin D deficiency symptoms needs of children and adults are.

The dosage of vitamin D preparations is mostly given in international units (IU). For severe vitamin D deficiency symptoms in adults, the doctor may prescribe high-dose preparations of 5,000 to 20,000 IU. With high demand in winter, 1000 to 5000 IU can be taken daily. In summer and during pregnancy, the dose should not exceed 2,500 IU daily. Babies are only allowed to receive 200 to 500 IU per day.

Final Question: Does Vitamin D Help With Weight Loss?

vitamin d deficiency symptoms

No, at least the results of a US study do not suggest that vitamin D helps lose weight. But you can not really expect everything from the supervisor. However, if there is a deficiency, it can help with symptoms such as fatigue in adults. And anyone who feels well rested is known to eat less. Already knew? Even drinking foods can help prevent vitamin D deficiency. For example, 100 g of drinking food Complete Fruity contains 1.1 μg of vitamin D3.
