The nervous system is the most complex organ in the human body, and it is the most essential. However nerve cells are particularly precious as, only like muscle cells, once formed, they do not replicate. This means that neural injuries cannot easily be replaced or repaired. Vitamin D seems to play a pivotal role in protecting these vulnerable and most important structures, but exactly how and to what extend is still subject to debate. Systematically reviewing the vast body of research on the influence of Vitamin D in various neuropathological processes, we found that Vitamin D particularly plays a mitigating role in the development of chronic neurodegeneration and the measured response to acutely acquired traumatic and non-traumatic nerve cells incidents. Adequate serum levels of Vitamin D before the initiation of these processes is increasingly viewed as being neuroprotective. However, comprehensive data on using it as a treatment during the ongoing process or after the injury to neurons is completed are much more ambiguous. A recommendation for testing and supplementation of insufficiencies seems to be well-founded.

Vitamin-D is not only an essential element in bone health, but it is also a pro-hormone. Deficiency of vitamin D is the most common cause of rickets and is also known to increase the risk of respiratory distress syndrome, lower respiratory infections, food sensitivities, asthma, type I diabetes, autism and schizophrenia. Vitamin D deficiency limits the effective absorption of dietary calcium and phosphorus. Vitamin D status in newborns is entirely dependent on maternal supply during pregnancy. Low maternal vitamin D status during pregnancy is a major risk factor for rickets in infants. Rickets in children is caused by severe, chronic vitamin D deficiency with apparent skeletal abnormalities, but neonates with vitamin D insufficiency have no overt skeletal or calcium metabolism defects. Rickets was a global disease in the early twentieth century. It has nearly disappeared in developed countries after its causal pathway was understood and fortification of milk with the hormone vitamin D was introduced at the population level. Surprisingly, rickets is re-emerging per recent evidence. Vitamin D deficiency is prevalent in both developed and developing countries. The chapter will review the prevalence of vitamin D deficiency in pregnant women and newborn population and its adverse effects on pregnancy and infant’s health. The chapter also describes evidence-based recommendations to prevent vitamin D deficiency in these vulnerable population.

Vitamin D deficiency is a pandemic issue due to decreased vitamin D intake from food and lessened sunlight exposure. Attention is drawn to vitamin D and its role learned in notable clinical disorders such as diabetes, cardiovascular disease and cancers including oral ones. Vitamin D is also very effective along with minerals in the protection of oral health. Vitamin D helps maintain the calcium-phosphate balance and contributes to the shaping of the bone. It is reported that with sufficient vitamin D level, the onset and progression of caries in the tooth structure can be stopped, the formation of caries can be reduced and enamel loss can be prevented. Vitamin D also affects the disease and health conditions of the periodontium. Anti-inflammatory and immunomodulatory functions have a role in the pathogenesis of periodontal disorders. It can reduce bone resorption and suppress the inflammatory outcome related to periodontal diseases by increasing mineral density. Vitamin D has been linked with tooth decay, gingivitis, and tooth loss. Vitamin D, in particular, as a promising oral health-protective agent, is said to lessen the incidence of caries and periodontitis.

Vitamin D plays an important role in bone metabolism. Vitamin D is a group of biologically inactive, fat-soluble prohormones that exist in two major forms: ergocalciferol (vitamin D2) produced by plants in response to ultraviolet irradiation and cholecalciferol (vitamin D3) derived from animal tissues or 7-dehydrocholesterol in human skin by the action of ultraviolet rays present in sunlight. Vitamin D, which is biologically inactive, needs two-step hydroxylation for activation. All of these steps are of crucial for Vitamin D to show its effect properly. In this section, we will present vitamin D synthesis and its action steps in detail.

Approximately 15% of patients with diabetes mellitus (DM) are prone to developing diabetic foot ulcers (DFU) in their lifetime. The term vitamin D status or 25-hydroxyvitamin D [25(OH)D] levels are used interchangeably to represent the status of vitamin D in individuals throughout this paper. Evidence suggests a relationship between 25(OH)D levels and DFU. However, very minimal data is available on the association between DFU and vitamin D deficiency. After a careful review of the literature, it was inferred that vitamin D could be associated with DFU and diabetic foot infections. Available evidence on vitamin D and DFU suggests a negative correlation between 25(OH)D levels and the presence of DFU. Evidence also supports a negative relationship between 25(OH)D levels and diabetic foot infections. Further large-scale randomized controlled studies need to be done to confirm the relationship between 25(OH)D levels and DFU including the use of vitamin D in the management of DFU and diabetic foot infections.
