Vitamin D Deficiency

What is it?

Hypovitaminosis D (low levels of Vitamin D)

Deficiency disease

Diagnosis measurements:

Measurement of serum 25-hydroxyvitamin D (25[OH]D) is the best test to determine vitamin D status. Levels of 25(OH)D are interpreted as follows :

  • 21-29 ng/mL (52.5-72.5 nmol/L): Vitamin D insufficiency
  • < 20 ng/mL (< 50 nmol/L): Vitamin D deficiency

Although not always required for the diagnosis of vitamin D insufficiency, measurement of the serum parathyroid hormone (PTH) level may help establish the diagnosis of vitamin D insufficiency. PTH levels are often elevated in patients with vitamin D insufficiency, indicating secondary hyperparathyroidism.

  • Periosteal bone pain in adults with severe vitamin D deficiency is best detected using firm pressure on the sternal bone or tibia

Breast fed milk formula drinking children and/or young children

Formula-fed babies being fed less than 500mls of baby formula per day:
Persons of this age group should have (7mcg – 8.5mcg) 280IU- 340IU of vitamin D in the form of multivitamin drops daily.
Infants will not need this dose until they are receiving less than 500ml of infant formula daily.

Children who are 6 months to five years old:

Persons of this age group should have (7mcg – 8.5mcg) 280IU- 340IU of vitamin D in the form of multivitamin drops daily.

(Infants will not need this dose until they are receiving less than 500ml of infant formula daily).
Do not buy high strength Vitamin D (beware of Vitamin D toxicity) without a blood test and then make sure your healthcare provider has given you advice on what dose and how much Vitamin D must take including dose and for how long (some doses are daily or weekly schedules and the length of time can vary too.
Consider recommended doses until then.

Vitamin D

  • Vitamin D is important because it increases the rate calcium is absorbed into your blood. Ask your doctor how much vitamin D you need.
  • To increase your calcium intake, you can add food rich in vitamin D to your diet.

These include:

    • fatty fish like salmon and tuna
    • fortified orange juice
    • fortified milk
    • Portobello mushrooms
    • eggs
  • As with calcium-rich dairy products, some vitamin D-rich dairy products can also be high in saturated fat.
  • Sunlight triggers your body to make vitamin D, so getting regular exposure to the sun can also help boost your vitamin D levels.
  • Sensible sun exposure, especially between the hours of 10:00 am and 3:00 pm produces vitamin D in the skin that may last twice as long in the blood compared with ingested vitamin D.

Lifestyle changes

In addition to maintaining healthy calcium and vitamin D levels, there are certain lifestyle changes you can make to promote bone health. These include:

  • Maintaining a healthy body weight
  • Exercising regularly
  • Restricting tobacco use and alcohol intake
