function
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

deficiency
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

deficiency symptoms diseases
RICKETS

Developed by little children

a disease characterized by a failure of bone tissue to properly mineralize

DEFICIENCY SYMPTOMS/DISEASES

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

people subject to deficiency
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)
toxicity symptoms
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
food sources
FOOD SOURCES
  • Cod liver oil
  • Fatty fish

statistics
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
interesting facts
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
