It’s most commonly used to treat vitamin D deficiency or associated disorders like rickets or osteomalacia.

Some individuals who may be at a higher risk of vitamin D deficiency

  • Older adults
  • Breastfed babies
  • People with darker skin
  • Obese individuals (or those who’ve had gastric bypass surgery)
  • People with conditions such as cystic fibrosis, Crohn’s disease, or liver disease

Food Sources include:

  • oily fish – such as salmon, sardines, herring, and mackerel
  • red meat
  • liver

  • fortified foods – such as some fat spreads and breakfast cereals

Vitamin D deficiency may lead to:

  • Fatigue.
  • Bone pain.
  • Muscle weakness, muscle aches, or muscle cramps.

Too much calcium will build up in the body if you take too many vitamin D supplements over a long period of time. This can cause bone deterioration as well as kidney and heart damage.
