vitamin D
Vitamin D is a fat-soluble vitamin that is important for bone and teeth health by helping the body absorb calcium and phosphorus. It is naturally found in few foods and is also produced in the body through sun exposure. A vitamin D deficiency can lead to rickets in children and osteomalacia in adults, which are conditions where the bones become soft and weak. Symptoms of deficiency include increased risk of cardiovascular disease, cognitive impairment, asthma, and cancer. Diagnosis involves checking dietary intake and sun exposure and treating any malabsorptive conditions. Treatment of a deficiency involves high dose oral or intramuscular vitamin D supplements.
