Surprised by vitamin D's ability to strengthen the immune system
Recent studies show that vitamin D has an important effect in strengthening the immune system, especially infections. So how does vitamin D affect the functioning of the immune system?
What is Vitamin D?
Vitamin D (also known as Calciferol) is a fat-soluble vitamin. Normally, the body does not synthesize vitamins and minerals on its own, but can only "load" through external food. However, vitamin D can also be synthesized by photochemistry. Under the influence of UVB ultraviolet radiation, the metabolism of substances under the skin will take place and form the active form of vitamin D in the body.
Vitamin D has two major physiological structures including vitamin D2 (Ergocalciferol) and vitamin D3 (Cholecalciferol). If vitamin D3 is synthesized under the skin by sunlight (accounting for 80-90%), vitamin D2 can be supplemented through foods such as seafood, fish or foods rich in vitamin D such as egg yolks, milk. , biscuits, cereals, etc. Although the body needs both vitamin D2 and D3, mainly vitamin D3 will occupy most of the integrated form in the body.
Vitamin D is an essential ingredient in building and maintaining strong bones. Because calcium is the main component of bones and the body can only absorb it when there is vitamin D. Therefore, vitamin D deficiency will affect health, manifesting in the form of rickets in children or osteoporosis in children. elder.
Vitamin D and its correlation with infections
Many studies have been done to demonstrate a correlation between vitamin D deficiency and infections. Preliminary observations suggest that malnourished rickets children tend to be more susceptible to respiratory infections. Vitamin D3 (isolated from cod oil) was "accidentally" used to treat infections such as tuberculosis before antibiotics were invented.
In fact, recent epidemiological studies have demonstrated a strong association between vitamin D levels and the incidence of various infectious diseases. This includes septic shock, influenza and respiratory infections.
Role and mechanism of action of vitamin D in the immune system
Vitamin D is expressed on immune cells such as B lymphocytes, T cells, Antigen Presenting Cells (APCs) and all these immune cells are able to synthesize vitamin metabolites. D, vitamin D can act by endocrine mechanism or secrete itself in the immune environment. The beneficial effect of vitamin D on immunity is partly due to its effect on the innate immune system.
Therefore, vitamin D also helps the body "fight" bacteria. That is also why vitamin D deficiency will directly affect immunity and increase susceptibility to infections, especially respiratory infections.
How to increase Vitamin D in the body
Some basic ways to increase vitamin D can be mentioned as:
Sunbathing (the ideal sunbathing time is before 8 am and around 4-5 pm. Each sunbathing lasts from 15 to 20 minutes).
Eat seafood that includes fatty fish such as salmon, tuna or shrimp
Eat foods rich in nutrients such as egg yolks, liver, cereals, etc.
Drink milk (milk contains both vitamin D and calcium)
Supplement vitamin D with functional foods if the body is not enough.
How to properly supplement vitamin D?
Like other vitamins and minerals, vitamin D needs to be supplemented properly so that the body does not fall into a state of excess or deficiency of the vitamin. In particular, if taking a daily vitamin supplement, just use low dose vitamin D3 (400IU) with both children and adults to strengthen antibodies. The following table describes in detail the required vitamin content for each subject at different ages.
