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 diseases1

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

  • Milk

  • Egg yolk

  • Beef liver

  • Mushroom


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
