According to him, the importance of vitamin D during winter lies in the reduced exposure to sunlight, because under the influence of ultraviolet rays the skin produces the vitamin, but this process is very limited in winter. A deficiency of this vitamin can lead to weakened immunity, chronic fatigue, decreased bone density, and an increased risk of catching colds.
He says: "Vitamin D is very important for children and adolescents, because a deficiency of it during the growth period affects the growth of the skeletal system, teeth, and muscular system. Children may develop symptoms similar to rickets, weakness, and delayed physical growth."
In addition, vitamin D is very important for older adults. As we age, our skin loses its ability to produce this vitamin, and our bones become more fragile. A vitamin D deficiency increases the risk of fractures and falls.
According to him, vitamin D is also essential for pregnant and breastfeeding women, as it plays a vital role in fetal bone development and supports maternal health. A deficiency can lead to pregnancy complications, weakened immunity, and developmental problems in the child.
The professor recommends that special attention should be paid to people with chronic diseases, metabolic disorders, obesity, and intestinal problems, as these conditions may reduce the absorption of the vitamin from food and exacerbate its deficiency.
For most healthy adults, vitamin D is also important in winter, but to a lesser extent, especially if a person’s diet does not include fatty fish, fortified foods and dairy products, and they have little exposure to sunlight, they should consult a doctor about taking vitamin D supplements.
The professor notes that experts recommend consuming foods rich in vitamin D during the winter months, such as fatty fish, seafood, eggs, and fortified dairy products. If necessary, a doctor can prescribe vitamin D supplements, determining the appropriate dosage for each individual case.
He says: "Vitamin D becomes extremely important in winter for children, teenagers, the elderly, pregnant women, and people with chronic diseases. Maintaining its ideal level helps strengthen the immune system, maintain bone health, and support general health during the winter season."
