![]() Benefits of Vitamin D for the Body: Important Facts and Recommendations Vitamin D is one of the main biologically active substances that is crucial for human health. It not only helps support the immune system, but also plays a key role in the absorption of calcium and phosphorus, which are necessary for the normal functioning of bones and teeth. Vitamin D can be obtained both through diet and by synthesis in the skin under the influence of sunlight. The role of vitamin D in the body The main function of vitamin D is to help in the absorption of calcium and phosphorus, which is extremely important for the normal development and maintenance of healthy bones and teeth. Insufficient levels of this vitamin can lead to various diseases, such as osteoporosis or rickets. Vitamin D also helps to normalize the functioning of the cardiovascular system, supports immunity, improves skin condition, and is also involved in maintaining muscle mass. Sources of vitamin D The main sources of vitamin D are sunlight, certain foods, and supplements. When the skin is exposed to ultraviolet radiation, it produces vitamin D. However, for many people, especially in regions with low levels of sunlight, this is not enough. In such cases, it is worth paying attention to foods rich in vitamin D, such as fatty fish (salmon, mackerel, tuna), egg yolks, mushrooms and fortified foods, such as milk and cereals. How to identify a vitamin D deficiency? Vitamin D deficiency may not appear immediately, as symptoms often develop gradually. However, they may include constant fatigue, bone pain, muscle weakness, depressed mood and frequent infections. To accurately determine the level of vitamin D in the body, it is necessary to undergo a laboratory test that will determine the level of 25(OH)D - the form of vitamin D that circulates in the blood. Consequences of vitamin D deficiency Long-term vitamin D deficiency can lead to serious health consequences. In children, this can cause rickets, a disease characterized by bone deformity and stunted growth. In adults, a deficiency in this vitamin can contribute to osteoporosis, increase the risk of fractures, and negatively affect muscle strength. In addition, there is evidence that low levels of vitamin D may be associated with an increased risk of developing cardiovascular disease, diabetes, autoimmune diseases, and even some types of cancer. Vitamin D intake levels The recommended daily allowance of vitamin D depends on age, health, and lifestyle. For adults, the recommended dose is 600 to 800 international units (IU) per day, and for people over 70 years of age, 800 IU. Pregnant and breastfeeding women also need increased amounts of this vitamin. However, before using supplements, you should consult a doctor, as excessive intake of vitamin D can lead to toxicity and disruption of the body's functioning. Vitamin D is extremely important for maintaining health. It promotes normal bone development, strengthens the immune system, improves muscle and cardiovascular function. However, to achieve optimal levels of vitamin D, it is important to follow a diet, spend enough time in the sun and, if necessary, take supplements. Early detection of vitamin D deficiency and correction of this condition will help maintain your health for many years. Ключевые слова:
