Role of Vitamin D in bone health 

It is very well clear that calcium and vitamin D are the two that play crucial roles in keeping bones healthy. Lack of any of these two in the body caused impaired bone health, weak muscles, and impaired growth. Basically, calcium is the major building block in the bone tissues as the tissues in the bones are strengthened by calcium. On the other hand, vitamin D plays the most important role in assisting the absorption of calcium from the food and to ensure the mineralization of bone tissue. Lack of bone mineralization is the primary cause of the occurrence of bone disorders. 

Some other body systems that are strongly associated with vitamin D levels are as follows: 

1. Immune system – Evidence showed that the level of vitamin D in the body is associated with the functioning of the immune system in the body. The immune system is the defense system that protects the body against the damage caused by bacteria, viruses, and other foreign invaders. The response of the immune system is of two types – innate and adaptive. 

  • The innate response is associated with defense against pathogens in which macrophages and monocytes provide defense. 
  • The adaptive response is associated with defense against a specific pathogen which is triggered by the activation of antigen cells in the jawed vertebrates. 

Vitamin D plays an important role in the normal and correct response of the immune system in the form of innate. It helps in killing the pathogens. 

2. Neurological system- As stated above the intake of vitamin D has positive effects on the mood of an individual, due to the impact of vitamin D on the neurological system. Not only mood, vitamin D levels have an association with various aspects of the neurological system. This is because vitamin D regulates the production of various factors in this system such as the growth of nerves that act as neuroprotective agents. 

3. Cardiovascular system – Yes!! Vitamin D levels in the body affect the cardiovascular system, or the heart as well. The most affected part is blood pressure. The blood pressure is defined as a pressure against the walls of the arteries. Deficiency of vitamin D is associated with high blood pressure. Research suggests that vitamin D deficiency is a risk factor for the development of pulmonary arterial hypertension, a condition in which the arterial pressure becomes too high that it makes it difficult for the heart to pump blood efficiently.
