Fatigue, cramps, dizziness… A vitamin D deficiency affects the immune system’s ability to protect us against infections. Tips to stop missing vitamin D with Dr. Nina Cohen-Koubi, nutritionist and psychosomatician.
Over there vitamin D plays an important role in the body. If this is lacking, the body can be exposed to more infections. The risk of shortage “is more important autumn winter because there is less sun” recalls Dr. Nina Cohen-Koubi, nutritionist and psychosomatician. What are the causes of? The implications ? Symptoms? And the treatments to cure it? Have some capsules is it a good idea? Answer with our contact person.
Vitamin D deficiency is the result of “A vitamin D concentration between 16 and 30 nanograms per millilitre of blood” and a shortage “by a concentration lower than 16 nanograms per millilitre of blood” explains Dr Cohen-Koubi. According to her, the deficiency must be determined by a blood test “to see its extent and whether it exists so that a doctor can suggest a prescription based on the results. If the person is around 28 or 29 ng/ml, he or she is not deficient and does not need to supplement with vitamin D.” To get your daily intake of vitamin D, there are two options:
- the sun. Vitamin D is produced under the influence of UV radiation in the skin. “It then goes to the liver and kidneys where it is activated” specifies our interlocutor.
- dietary intake from foods such as oily fish (salmon, herring, sardines, etc.), dairy products and cod liver oil.
“I don’t recommend self-medication, even capsules.”
Vitamin D deficiency can be detected by characteristic symptoms and signs:
- Muscle weakness.
- “The patient may also feel pain in the muscles,” explains Dr Cohen-Koubi, because the body no longer has the vitamin that promotes muscle fibre renewal.
- Unusual fatigue.
- Muscle cramps.
- Signs of dry skin.
- Of the signs of depression: “A vitamin D deficiency can impact morale because serotonin is less well regulated.”
- Weight gain. “When there is a deficiency, the body regulates insulin less well and the person tends to crave more sugar and gain weight.”
- Tingling may occur “Certainly because of the lack of vitamin D and its effect on the muscles.” However, the expert adds that these tingling sensations could also be due to a potassium or magnesium deficiency.
Vitamin D deficiency can be treated with these natural solutions:
→ The nutritionist recommends exposing yourself to the sun for 15-20 minutes daily if possible and consuming foods rich in vitamin D more regularly.
→ Turn to nutritional supplements in various forms, including prescription ampoules. “These are very useful to give the patient a boost”, explains the nutritionist. However, you must respect the dosage because taking too much vitamin D can cause an overdose: “I advise against self-medication—even capsules. Without blood tests and medical advice, the patient does not know whether he has a deficiency and what the extent of it is. He therefore runs the risk of consuming more vitamin D than he needs.” warns Dr. Cohen-Koubi.
→ At menopause : “For postmenopausal women, the elderly or people with osteoporosis, taking Zyma D3® drops daily is highly recommended.” to maintain bone strengthening. Vitamin D3 is the one that is best absorbed by the human body.
→ The children can also take prescription vitamin D.
The human body does not produce vitamin D itself. Its contribution must therefore be external. The causes of a deficiency can be several:
- The lack of sun. The sun is one of two sources of vitamin D: “If the patient is not exposed for between 15 and 20 minutes per day, with the face and arms uncovered, the body will not produce enough vitamin D to meet daily needs.”
- a diet is not balanced enough. “Foods rich in vitamin D are essential to prevent deficiencies” explains the nutritionist. “But without sunlight, these foods may not be sufficient and supplementation may be necessary.”
|Role of vitamin D
A vitamin D deficiency has several consequences for the body:
→ About the immune system: “Vitamin D is essential for strengthening immunity” reminds the nutritionist. When deficient it weakens. Especially if the person is stressed: “Stress, morale, diet, they all play a role in having an effective immune system” continues our interlocutor. a study of March 2020, published by Inserm, highlighted the relationship between stress and reduced immune system functioning. Stress hormones stimulate receptors called “β2-adrenergic” and researchers discovered “that β2-adrenergic receptors specifically inhibit the response of certain immune cells, Natural Killer (NK) cells. Stimulated by stress hormones, β2-adrenergic receptors prevent these Natural Killers from producing a certain type of cytokine necessary for the elimination of viruses.
→ Lack of vitamin D and COVID-19: “We found that a large number of people who developed severe forms of COVID-19 were deficient in vitamin D. Although this observation is interesting, we cannot at this time confirm that the absence of vitamin D deficiency allows the prevention of Covid-19 infection. Studies are underway to find out whether vitamin D may play a role in the prevention or treatment of COVID-19.” explains Dr. Cohen-Koubi.
→ Vitamin D deficiency can also lead to muscle strain, dizziness weight gain, tingling, the signs of dry skin or even cause it unusual tiredness.
