Depression, anxiety, loss of sleep, impaired performance are ones of the most common symptoms in the modern world. A quickening pace of life, stressful events and the inability to influence on them are known causes for concern, aren't they?
How to cope with loads and rise to the challenges of our time? Is there a way and what can we do to increase the body’s resources?
Such resources are likely to be already inherent in all of us by nature, they just need to be “activated”.
Vitamin D is our rescue resource
Have you ever stopped to think why we do not feel alert especially at the end of winter or do not have enough strength even for daily routine activities, and our mood is often depressed? How impatiently and gladly we expect warm rays and sunny days in spring, when a smile suddenly appears on our face!
Our body reminds us that the Sun is a source of energy for all living things, and it is the same necessary component of health as clean water and air.The most well-known mechanism through which the rays of the sun realize their effects on the human body is the synthesis of vitamin D in the skin. Apart from visible light, solar radiation that reaches the Earth includes ultraviolet (UV) waves. Cholecalciferol (the same vitamin D) is produced in our skin under the action of a certain spectrum of this ultraviolet. In autumn, winter and early spring, there is no necessary UV radiation in our latitudes, or it is too low for the synthesis of this key biologically active substance.
The modern urban lifestyle has led to the fact that the prevalence of vitamin D deficiency is in the nature of a pandemic and reaches 80-90%.
Conventional foods contain a very small amount of vitamin D, so it is almost impossible to get enough vitamin D through your diet. Vitamin D deficiency is gradually formed. First of all, it can manifest itself in such non-specific signs as weakness, impaired performance, depressed mood, sleepiness, apathy, and vulnerability to stress. A higher frequency of infectious diseases, the exacerbation of chronic processes, muscle and bone pain, and decreased bone density – osteoporosis are attached in the following.
Such a wide range of symptoms is due to the role of a universal regulator that vitamin D takes on in the human body. Cholecalciferol regulates not only the exchange of calcium and phosphorus, but also has an effect on the activity of parts of the human genetic apparatus through special intracellular receptors.
Vitamin D receptors are found on most types of human cells. Therefore, it is recognized that cholecalciferol is more correctly called a "prehormone", an analogue of other steroid hormones in the body, rather than a "vitamin". However, according to tradition, the term "vitamin D" is generally accepted.The activity of up to 10% of human genes (and other vertebrates) has been established to be regulated by vitamin D.
The effect of vitamin D on immunity
To illustrate the significance of vitamin D as an activator of human natural resources, we should mention its role in the regulation of immunity. Cholecalciferol contributes to the proper formation and maturation of cells of the immune system, takes part in the regulation of the nature and severity of an immune response to viruses and microbes, reduces the activity of autoimmune processes, and stimulates antitumor protection.
Studies have convincingly proven an almost two-fold decrease in the incidence of acute respiratory viral infections (ARVI) in patients with optimal concentrations of vitamin D compared with patients with its deficiency.
In relation to coronavirus infection, the correlation between a higher concentration of vitamin D, a decrease in the incidence and severity of COVID-19, a lower rate of mortality among patients has been proven.
The effect of vitamin D on emotions, mood and mental health
One of the first visible effects of taking vitamin D preparations registered by consumers is a surge of strength and energy.
In the brain, vitamin D contributes to the transmission of signals between cells and the formation of new synapses, sites for the exchange of information between nerve cells, regulates the processes of cell purification from metabolic products, and prevents the death of neurons.
Vitamin D in its active form is associated with the formation of serotonin in the brain and has a protective action if the levels of serotonin and dopamine are reduced.
This explains why current meta-analyses (studies with the highest level of evidence) consistently show a decrease in depression when taking vitamin D. The ability to control negative emotions and life quality when providing optimal levels of vitamin D also improves.The normal duration of sleeping, a feeling of freshness and vitality after sleep are associated with vitamin D levels.
Now then, vitamin D is necessary to maintain normal mood, cope with existing negative factors and prevent depression.
The importance of vitamin D for the mental and neurological sphere is also shown in relation to more severe mental diseases. For example, various studies have shown that:
vitamin D reduces the risk of developing schizophrenia;
contributes to the elimination of amyloid proteins — the cause of Alzheimer's disease;
reduces the frequency and severity of exacerbations of multiple sclerosis.
In case of Parkinson's disease, dementia, epilepsy, positive results of using this vitamin have been noted. Therefore, it is necessary to maintain optimal concentrations of vitamin D as a comprehensive approach to the treatment and control of these diseases.
Vitamin D takes on a role throughout a person's life. The deficiency of this important substance during pregnancy can leave an imprint on an unborn baby for the rest of his life. The frequency of autism spectrum disorders (in other words, autism) in children born to mothers with insufficient concentrations of vitamin D is significantly higher compared to those who have sufficient levels of cholecalciferol.
Apart from sufficient levels of vitamin D, the balance of other vitamins and nutrients, keeping a daily routine and proper rest, a time limit for gadgets, communication with family and friends, and, if necessary, psychotherapy take on an important role.
The intake of vitamin D — how, when and how much
To use all the opportunities given by nature, it is necessary to maintain a normal supply of vitamin D. The optimal concentration is considered to be 25(OH)D within the range of 40-60 ng/ml (normal limits from 30 to 100 ng/ml).
Modern laboratories determine this parameter easily. Consult your doctor if your level of vitamin D is below or above the normal range.
To maintain optimal concentrations of vitamin D, adults are recommended to take from 1000 to 4000 IU of cholecalciferol per day. The characteristics of vitamin D metabolism allow its intake in high-dose forms, but in a convenient way once per week, once every two weeks or even once per month. For example, you can take only one tablet of 50000 IU once every two weeks to meet your needs of cholecalciferol and realize all the positive effects of its use. It is important that the safety of this intake is fully maintained with such a convenient mode of use.
A special matrix structure of these tablets guarantees the accuracy of dosing and safety of the active substance to ensure your convenient, effective and safe intake of vitamin D.
Do not put off the chance to restore the resources given by nature and enjoy every day of your life!
Be healthy and have a good mood!
