Vitamin D is a nutrient from sunlight and when sunlight is not available (in sufficient quantity) then it starts lacking in the body. To overcome its deficiency, it is advised to take vitamin D pills. However, vitamin D requirements vary from person to person and also depend on various ethnic groups. A study published in the Journal of Metabolism, Clinical and Experimental showed that people who have less than 20 nanograms per ml of blood have vitamin D deficiency in their body. All laboratories are now implementing efforts and better tests are being made to improve the results of different laboratories than before.
Coming back on vitamin D, its main function is to absorb calcium in our body.
Vitamin D deficiency
Vitamin D deficiency can inhibit the development of the skeletal system as well as cause rickets (a disease) in children. Besides, vitamin D deficiency in adults, it also increases the risk of bone fractures and osteoporosis. To prevent rickets, calcium intake is necessary, but for better results, it is also important to take vitamin D along with it.
Taking these supplements can be quite beneficial for elderly people (adults). It also improves the:
- the immune system
- cancer and
- heart health
But beware, as its intake in large amounts is also harmful to the body, as this increases the risk of bone fractures.
Intake of Vitamin D
According to the National Academy of Medicine, vitamin D intake per day should be:
- 400 IU for infants
- 600 IU for people 1 to 70 years old
- 800 IU for people over 70 years old
Some studies have shown that regular intake of vitamin D results in lower mortality and experts suggest that its intake is very good (beneficial) for the immune system, cancer, and heart health.
