Vitamin D is produced by the skin after exposure to sun rays that contain ultraviolet B light. It is extremely important for the absorption and fixation of calcium and phosphorus in the body, and for the formation and maintenance of bone strength. The most important forms of Vitamin D are ergocalciferol (Vitamin D2) and cholecalciferol (Vitamin D3).
The bone system, the main beneficiary of Vitamin D3
The most well-known role of Vitamin D in the body is to maintain normal levels of calcium and phosphorus in the blood, being one of the major contributors to calcium intake in the body. Without absorption and fixing a sufficient amount of calcium, the strength and bone density decreases and increases the risk of problems with the bone system.
In children with insufficient vitamin D3 in their bodies, it leads to rickets. Adults over 30 years of age experience a significant slowing of the bone tissue regeneration process. In addition, after the age of 50-55 years, in order to reduce the risk of specific conditions of this period, such as osteoporosis, diseases caused mainly by bone fragility, the external contribution of the substance is extremely important.
Vitamin D3 also supports the muscular system
Recent research has highlighted other benefits of Vitamin D3, in addition to those for the bone system. This contributes to the normal functioning of the muscular system, which can be weakened when the vitamin is found in insufficient amounts. Another beneficial aspect of Vitamin D3 for the muscular system is the reduction of muscle spasms.
The immune system and vitamin D3
The immune system is another structure of the body that Vitamin D3 has beneficial effects on. Research has shown that adequate intake of vitamin D3 can bring significant benefits to the immune system. One benefit is, for example, that vitamin D3 is involved in the normal cell division process.
