Besides treating and preventing a range of disease, vita- min D has also been applied in managing minor abnormalities so as to improve quality of life.
Periodontal disease is a common chronic inflamma- tory disease characterized by loss of periodontal attach- ment. It is the leading cause of tooth loss [146-150] which has a great impact in nutrient intake the quality of life [151-153]. Several epidemiologic studies revealed that there is link between osteoporosis and tooth loss, which indicate that the cause of osteoporosis could also contribute to periodontal disease. A 3-year study showed that supplementation with vitamin D (700 IU/d) plus calcium (500 mg/d) significantly reduced tooth loss in older people [154].
Mood changes with season, a common phenomenon is that anxiety and depression increase during winter months. An extreme case of this seasonality is a clinical syndrome called seasonal affective disorder (SAD), also known as winter depression. One explanation is the changing level of vitamin D3 during winter. One study, including 44 healthy subjects during winter, investigated the efficacy of vitamin D3 in enhancing mood. Results on a self-report showed that vitamin D3 significantly enhance positive affect [155].
Vitamin D has also been found to play an important role in brain development and function [156-159]. The study pointed out the wide distribution of vitamin D receptors throughout the brain. It showed that vitamin D has the ability to affect proteins which are known to be directly involved in learning and memory, motor control, and pos- sibly even maternal and social behavior [160].
