One billion people worldwide suffer from vitamin D deficiency
We can only get enough of this important vitamin by getting enough sunbathing or taking the right dietary supplements.
Hair loss, depression, fatigue, skin diseases, cancer are some of the health-related phenomena associated with vitamin D deficiency. Despite the media noise and new awareness surrounding the sunshine vitamin, few people manage to consume enough of it. According to the FFAs (French Fund for Food and Health), 43 to 50% of adults in France are deficient.
80% of vitamin D is produced by our body through sunlight. However, in winter, between the time change and bad weather, the body is much less exposed to the sun's rays. Scientists actually talk about 5 fat-soluble vitamin Ds since they can be stored in the body. Produced by the latter, they are considered hormones.
Having an essential role for the bones, a vitamin D deficiency can promote fatigue, depression or even dry skin. Nearly 80% of the Western population, and even the majority of the elderly are affected by this health problem, according to a report by the French Academy of Medicine (AMF). Discover the six signs that prove that you are also deficient in vitamin D.
1/ A feeling of fatigue and exhaustion
All of these vitamins D stimulate the absorption capacity of calcium and phosphorus, a mineral, of the intestine by regulating their content in the blood. They also help fight fatigue and boost the immune system. Deficient, it becomes more difficult to be energetic.
2/ Muscle weakness
Vitamin D plays an essential role in maintaining muscle mass. A French study reveals that a lack can lead to sarcopenia, an abnormal decrease in muscle strength and mass. In seniors, these deficiencies are often associated with muscle loss.
3/ A depression
Winter depression is often linked to a lack of light. According to researchers, there is a link between vitamin D deficiency and depression. An Austrian study of 25 depressive patients showed that they reported lower vitamin D levels than healthy individuals. Scientists believe that the hormone would protect the neurons that synthesize dopamine and serotonin. Two neurotransmitters essential for the proper functioning of the brain.
4/ Dry skin
Abnormally dry skin can be caused by a vitamin D deficiency. The latter is involved in the hydration of the skin and tissues. It also helps to overcome certain skin diseases.
5/ Bone fragility
A deficit causes bone fragility. Loss of bone strength, redundancy of fractures, joint pain can be linked to a deficiency. Children can be prone to rickets. A disease of the growing bones that manifests in growth and development delays as well as sleep disturbances.
The dryness caused by vitamin D deficiency can also affect joint lubrication. Result ? You suffer from pain, cramps and stiffness upon waking.
Lack of sunlight can generate vitamin D deficiencies (it is produced by the body under the effect of exposure to sunlight). However, several studies have proven that this vitamin is beneficial for morale.
Vitamin D comes into action in bone and dental formation, by interacting with calcium. It is a vitamin that can be assimilated through food, but also through the rays of the sun when they penetrate the skin. Vitamin D is also essential for good muscle health.
Both a vitamin and a prohormone, vitamin D is vital for healthy bones and teeth. Indeed, it plays an essential role in the metabolism of calcium in the body. It regulates blood calcium levels by improving the intestinal absorption of this mineral, while minimizing its elimination through urine. It also participates in the deposition and withdrawal of calcium from the bones, according to the needs of the body. "Calciferol", another name for vitamin D, comes from Latin and means "which carries calcium".
Vitamin D has also been called the "anti-rachitic vitamin" because rickets, a growth disorder, is caused by vitamin D deficiency. In North America, as well as in many industrialized countries, small amounts of vitamin D to milk and margarine in order to prevent this disease.
Regarding Covid-19, the first reports show that the circulating concentration of 25(OH)D is lower in infected adults than in others. In an ecological study, inverse correlations were found in 46 countries between vitamin D deficiency in the general population and the incidence of Covid-19. More specifically, the existence of vitamin D insufficiency seems to precede the incident onset of Covid-19, and not the reverse.
