Vitamins are daily necessities and without them, people will start notice deficiency issues. For example, Vitamin A assists in proper cell division and helps prevent cancer, while those who are deprived of Vitamin A suffer from night blindness and dry corneas. Conversely, overdosing on vitamins can become a hindrance to the body. For instance, overdosing on Vitamin A will lead to birth defects, coarse bone growths, hair loss, skin dryness or peeling, vomiting, and pressure around the brain. This information should be of interest to nursing students, because registered nurses are able to help and educate people with vitamin deficiencies. These deficiencies can cause serious health issues, and more nurses are needed to work with patients and their concerns.
