Not only helps the body absorb calcium effectively, vitamin D also participates in many other biological functions such as maintaining the immune system, supporting muscle health and contributing to protecting cardiovascular health.
However, vitamin D deficiency is currently quite common due to a lifestyle that is less exposed to sunlight and an unbalanced diet.
One of the most prominent roles of vitamin D is to support the absorption of calcium and phosphorus in the intestines. These are two minerals necessary for the formation and maintenance of a strong bone and tooth system.
When the body lacks vitamin D, calcium absorption is significantly reduced, increasing the risk of osteoporosis, fractures in adults and rickets in children. Maintaining enough vitamin D is an important factor in developing a healthy bone system throughout life.
In addition to its benefits for bones and joints, vitamin D also plays a role in supporting the immune system. Many studies show that vitamin D participates in regulating the activity of immune cells, helping the body increase its ability to fight disease-causing agents such as bacteria and viruses. People who lack vitamin D are often at higher risk of respiratory infections than people with sufficient vitamin D levels.
Vitamin D also contributes to maintaining muscle function. In older adults, vitamin D deficiency can reduce muscle strength, increase the risk of falls and injuries. Adequate vitamin D supplementation combined with a reasonable exercise regimen helps maintain mobility and improve the quality of life.
Natural vitamin D sources mainly come from sunlight. In addition, some foods such as salmon, mackerel, sardines, egg yolks, vitamin D-enhanced milk and mushrooms also provide this nutrient.
Vitamin D plays an important role in bone health, immune system and muscle function.
Maintaining adequate vitamin D levels through diet, reasonable sun exposure and supplementation when necessary is an effective way to protect long-term health.
