Vitamin D3, often referred to as the sun vitamin, plays an essential role in the proper functioning of the body. It is formed in the skin under the influence of UVB rays. So it would seem that in summer, when the days are long and sunny, vitamin D3 supplementation is not needed. But does everyone really produce adequate amounts of it during the warm months? In this article we will take a closer look at this issue and dispel doubts about whether to take vitamin D3 in the summer.
The role of vitamin D3 in the body
Vitamin D3 is essential for many biological processes. The most important of these are:
- Regulation of calcium and phosphate metabolism;
- Supporting mineralization of bones and teeth;
- Supporting the work of the immune system;
- Protection against autoimmune diseases;
- Beneficial effects on mood and nervous system.
Vitamin D3 deficiency can lead to weakened bones (osteoporosis), decreased immunity, chronic fatigue and, in children, rickets. This is why it is so important to maintain adequate levels of this substance in the body throughout the year.
Vitamin D3 supplementation in summer – is it necessary?
During spring and summer, many people forgo supplements, believing that exposure to the sun will satisfy the body’s needs. In reality, this is not always the case. It depends on many factors, including:
- lifestyle – people who work indoors have limited contact with the sun;
- the use of creams with UV filters, which block the synthesis of vitamin D3 in the skin;
- The time of day spent outdoors – synthesis occurs mainly between 10:00 am and 3:00 pm;
- skin complexion – people with darker skin produce less vitamin D3;
- age – in seniors, the skin’s ability to synthesize is much lower.
Therefore, even in summer, some people may be at risk of deficiency. Vitamin D3 supplementation may therefore also be advisable during the warmer months, especially for those in the risk groups mentioned above.
Vitamin D3 supplements – which ones to choose?
When deciding on supplementation, it is advisable to choose products from reputable companies that offer high quality preparations and adequate doses of vitamin D3. One such manufacturer is Herbapol Poznan, whose offer can be found at https://herbapol.poznan.pl/. Vitamin D3 preparations for both adults and children in various forms are available there.
Summary
Although summer promotes the natural production of vitamin D3, it does not always guarantee sufficient levels in the body. Lifestyle, individual predisposition and limited sun exposure are factors that can hinder effective synthesis of this important component. Supplementation of the substance may also be warranted in summer especially in at-risk individuals. To make sure that the body is getting what it needs, it’s worth doing the appropriate tests and using proven preparations if necessary.
