Also called calciferol, vitamin D is known for its multiple roles in the body. Assimilated nowadays to a hormone, its unfortunately too widespread deficiency is responsible for many pathologies. Discover in this post the benefits of this essential vitamin for your health!
Vitamin D, a dual origin vitamin
Vitamin D is a liposoluble (fat soluble) vitamin known for its action in bone mineralization. It has a double origin. It can indeed be exogenous or endogenous. In addition, it exists in two forms: vitamin D2 and vitamin D3.
Vitamin D2 is of vegetable origin and is strictly exogenous. It is not as well assimilated as vitamin D3. Of animal origin, the latter is synthesized in the epidermis. Rather, it is a hormone whose synthesis is dependent on ultraviolet B (UVB) rays from the sun.
Vitamin D3 can to a lesser extent come from food. However, few foods contain it and most often in small quantities. Therefore, the main source of calciferol is solar synthesis by the skin. It is for this reason that many people suffer from its deficiency, especially during the winter and autumn months when the sun is not very present.
Under these conditions, you can opt for a 100% natural food supplement rich in vitamin D. It is made from plants, fruits or food and is well indicated to overcome a calciferol deficiency. You can find it in oily form or in capsules. However, be sure to respect the prescribed dosages and inform your doctor before starting such a cure.
Vitamin D, a great health ally
Whether it comes from your food supplements or whether it is synthesized by the body, vitamin D is essential to your well-being. This is explained by the fact that it is involved in many biological processes.
Promote bone health
Calciferol promotes intestinal absorption and skeletal binding of calcium and phosphorus. This action maintains or even increases bone mineral density. Vitamin D thus plays an active role in the mineralization and consolidation of bone tissue and teeth. It is for this reason that it is very indicated in prevention and treatment of osteoporosisa very common pathology in postmenopausal women.
Strengthen the immune system
Vitamin D would also stimulate and strengthen the immune system. It could play a decisive role in the protection against certain autoimmune diseases, that is to say conditions during which the body produces antibodies directed against its own tissues. This is for example the case of type 1 diabetes or rheumatoid arthritis.
Vitamin D also plays other roles in the body, as certain studies tend to show. According to recent studies, it actively participates in the functioning of muscles. It promotes the contraction and renewal of muscle fibers. This is particularly important in seniors where the risk of falling is high due to low muscle tone.
Similarly, some researchers believe that this vitamin could reduce the risk of cardiovascular disease, especially in the elderly. It is also attributed a beneficial action in the prevention of the decline of intellectual faculties and other cognitive disorders.
Vitamin D deficiency, serious consequences
Manifestations of vitamin D deficiency are not long in making themselves felt. Some symptoms are unmistakable. These include, among others:
- feeling of intense fatigue and exhaustion,
- muscle cramps and weakness,
- leg pain,
- dehydration of the skin…
Beyond these symptoms, vitamin D deficiency can have serious consequences for the body at any age.
In the youngest, for example, it is responsible for a lack of mineralization of the bones and a deformation of the spine: this is rickets. However, this disease is increasingly rare thanks to almost systematic supplementation and enrichment of infant formula.
In adults, vitamin D deficiency often causes skeletal demineralization or osteomalacia. This disease is usually associated with convulsions, hypocalcemia, or even tetany. In addition, according to some studies, this deficiency increases the risk of cancer, infection and cardiovascular disease.
In addition, a low intake of calciferol is also the cause of seasonal depression. The explanation of this depressive state is at the level of the hippocampus. This part of the brain that regulates moods is rich in vitamin D receptors.
Ultimately, vitamin D plays a key role in the body. It is involved in many metabolic processes. Mainly synthesized in the skin in the presence of the sun, it can also come from food. In case of deficit, 100% natural food supplements can be excellent allies provided you use them properly.
