The benefits and harms of vitamin D are an interesting question because human health depends on this vitamin in many ways. It is necessary to understand the purpose of the substance, find out where it is contained and understand whether there is a danger in it.
Vitamin D is necessary for the child for the proper development of the skeleton and the timely appearance of teeth. Deficiency of this element leads to metabolic disorders, autoimmune diseases and the body’s inability to resist viruses and infections. If a child from the first year of life will experience a shortage of such a vitamin, there will be a risk of developing rickets. Drugs containing this element should be taken after consulting a doctor.
We need vitamin D when we are young in order to develop our skeleton normally. Babies need it for the proper formation of teeth and bone tissue. Without this vitamin, the immune and endocrine systems will not work properly.
Here are the main benefits of Vitamin D:
- regulates the growth of muscle tissue;
- forms a healthy epithelium of the skin;
- has a beneficial effect on the development of blood vessels and the heart;
- strengthens the immune system;
- promotes rapid absorption of calcium;
- takes part in the production of peptides, thanks to which the organism is protected from microbes;
- normalizes blood pressure and insulin levels;
- supports the nervous system;
- reduces the likelihood of an inflammatory process;
- reduces the risk of rheumatoid arthritis, diabetes, multiple sclerosis, neoplasms.
Children’s body does not have its own reserves of vitamin D. It is received by the child along with the adapted mixtures or the mother’s milk. Due to the fact that small children are not allowed sunbathing, doctors recommend taking oil drops.
The dosage depends on the following factors: age of the child; season. Breastfed babies who are given complementary foods are allowed to use drops or ready-made cereals enriched with calciferol. For the prevention of rickets, vitamin D should be taken in the fall and winter. In the warm season recommended the natural development of the element. The younger the child, the more he needs calciferol. After 3 years, pharmaceutical preparations containing vitamin D cease to be given, since the body itself begins to produce it.
When many people reach the age of 50, they begin to experience problems with their joints – arthritis, osteoporosis, rheumatism develops, slouching appears, the condition of teeth and hair worsens. The bones in old age become fragile, the skin ages, the body begins to synthesize worse the substance that comes along with sunlight. Also, its absorption from food worsens.
For these reasons, the benefits of vitamin D for the human body are particularly pronounced after 50 years. Vitamin complexes help strengthen the bone and nervous system, support the work of blood vessels, heart and brain, protect the body from a wide range of dangerous diseases.
The benefits of vitamin D for adults is that the substance and its concentration in the body directly affect body weight. Scientific studies show that in people with excess weight, the level of the desired substance is markedly reduced. A normal level of vitamin D contributes to maintaining a healthy weight. With a tendency to corpulence, it is recommended to closely monitor the indicators of an important substance in the body.
Despite all the harm from a lack of substance, its overabundance does not bring anything good either. An overdose of vitamin D is expressed in weight loss and redness of the eyes, discomfort in the muscles and poor appetite. Vomiting and diarrhea are also common.
You should note that for a pronounced hypervitaminosis this vitamin must accumulate in the body in significant amounts.
It is not recommended to take vitamin D if you have problems with:
- hypercalcemia, that is, an excess of the Calcium mineral in the body;
- active tuberculosis;
- an ulcer;
- kidney failure and other chronic kidney ailments;
- ischemia and atherosclerosis.
Since the substance is completely natural to the human body, allergy, as such, does not happen to it. However, this word is often called the negative reaction of the body to low-quality preparations with vitamin. Cheap supplements often contain flavors, sucrose, citric acid, and other potentially allergenic constituents.
In addition, an overdose of a substance is often mistaken for allergies, especially in children. A negative reaction to the properties of the element usually occurs in the form of diarrhea, vomiting, fever, skin rash and edema.
