  1. Vitamin D Nabila Anwara, Razia Begum, Kelly Chen, Haesol Jun, David Zhou

  2. FUNCTION • Needed for bone growth & remodeling • Supports tooth formation & muscle, nerve funtion • Maintain normal blood levels of calcium and phosphorus • Essential for promoting: - calcium absorption in the gut - maintenance of serum calcium - mineralization of bones - prevention of hypocalcemic tetany

  3. DEFICIENCY • CAUSED BY: - dietary inadequacy - impaired absorption - increased requirement - increased excretion - usual intake < recommended levels over time - exposure to sunlight is limited - kidneys malfunction - Inadequate absorption from the digestive tract

  4. RICKETS Developed by little children a disease characterized by a failure of bone tissue to properly mineralize DEFICIENCY SYMPTOMS/DISEASES

  5. DEFICIENCY SYMPTOMS/DISEASES • MAY LEAD TO: - at least 17 varieties of cancer - heart disease - stroke - hypertension - autoimmune diseases - diabetes - depression - chronic pain - osteoarthritis - osteoporosis, and more

  6. PEOPLE SUBJECT TO DEFICIENCY • Elderly • Obese individuals • Exclusively breastfed infants • People who have limited sun exposure • Individuals who have fat malabsorption syndromes (e.g., cystic fibrosis) or inflammatory bowel disease (e.g., Crohn's disease)

  7. TOXICITY SYMPTOMS • Toxicity can raise blood levels of calcium, causing mental status changes such as confusion and heart rhythm abnormalities • Can lead to the increase risk of developing kidney stones • Can cause nonspecific symptoms such as nausea, vomiting, poor appetite, constipation, weakness, and weight loss

  8. FOOD SOURCES • Cod liver oil • Fatty fish • Milk • Egg yolk • Beef liver • Mushroom

  9. STATISTICS • 40% of the U.S. population is vitamin D deficient • 42% of African American women of childbearing age are vitamin D deficient • 48% of young girls (9-11 years old) are vitamin D deficient • Up to 60% of all hospital patients are vitamin D deficient • 76% of pregnant mothers are severely vitamin D deficient, causing widespread vitamin D deficiencies in their unborn children. • Up to 80% of nursing home patients are vitamin D deficient. • People living in areas with less sun exposure (ex. Sweden, Minnesota) are more susceptible to vitamin D deficiency

  10. INTERESTING FACTS • UV Light (from sun) is responsible for vitamin D production. As little as 10 minutes of exposure everyday prevents Vitamin D deficiency • Theories suggest vitamin D production is accountable for the different skin colors among races • Theories suggest migration from Africa to the North (less sunlight) led to lighter skin to increase in vitamin D production
