— a vitamin that plays an important role in calcium-phosphorus metabolism. Sufficient vitamin D3 is essential for effective calcium absorption, which in turn ensures normal bone and tooth formation in children and maintains bone strength in adults. A lack of vitamin D3 leads to rickets in children and osteoporosis in adults, and also adversely affects the condition of skeletal muscles.Note that this vitamin can not only be supplied with food but also synthesized in human skin under the influence of ultraviolet light of a certain range. Sunlight is especially effective in this sense in the morning and evening. However, many people do not get enough of this vitamin: for example, dark skin is less susceptible to ultraviolet radiation, the effectiveness of this process decreases with age, and in modern cities with a polluted atmosphere, a person simply does not receive the right amount of “useful” UV radiation due to atmospheric pollution or permanent stay indoors — window glass practically does not transmit ultraviolet light. Therefore, even in summer, an additional intake of vitamin D3 may be useful, not to mention the winter season with a decrease in the amount of sunlight.
