[19] [20] Emerging studies have suggested a link between vitamin D deficiency and COVID-19 symptoms. [21] [22] A review has shown that vitamin D deficiency is not associated with a higher chance of having COVID-19 but is associated with a greater severity of the disease, including 80% increases in the rates of hospitalization and mortality.

A long-term deficiency in vitamin D can lead to osteoporosis, a disease that causes bone density loss, which can increase the risk of fractures and broken bones. Osteoporosis itself can also cause ...
This condition can be caused by vitamin D, calcium or phosphorus deficiency. [86] Vitamin D deficiency remains the main cause of rickets among young infants in most countries because breast milk is low in vitamin D, and darker skin, social customs, and climatic conditions can contribute to inadequate sun exposure.
Common, most foods do not contain vitamin D, indicating that a deficiency will occur unless people get sunlight exposure or eat manufactured foods purposely fortified with vitamin D. Vitamin D deficiency is a known cause of rickets, and has been linked to numerous other health problems. [46] [47] Vitamin E deficiency
Heart Health: This area is less studied, but growing evidence shows that vitamin D could protect against cardiovascular disease. When estrogen levels drop during menopause, women’s risk of heart ...
Vitamin D deficiency, especially in early life, is linked to an increased risk of autoimmune conditions, such as type 1 diabetes. Autoimmune diseases can be caused by a failure of T cells, a type ...
The most common cause of osteomalacia is a deficiency of vitamin D, which is normally derived from sunlight exposure and, to a lesser extent, from the diet. [10] The most specific screening test for vitamin D deficiency in otherwise healthy individuals is a serum 25(OH)D level. [11]
One proposed mechanism linking vitamin D to Parkinson's disease involves the Nurr 1 gene. Vitamin D deficiency is associated with decreased expression of the Nurr1 gene, a gene responsible for development of DA neurons. It is therefore plausible that a lack of Nurr1 expression leads to impaired DA neuronal development. Failure to form DA ...
