Vitamin D Deficiency

What is Vitamin D deficiency?

Vitamin D deficiency means your body doesn’t have enough vitamin D to keep your bones, muscles and brain cells healthy. Vitamin D is important for absorbing calcium and maintaining strong bones and supports your immune system.

Without enough vitamin D, you may experience weak bones, muscle pain, or tiredness, and children may develop a condition called rickets.

What causes Vitamin D deficiency?

  • Not enough sun exposure: Sunlight is the main source of vitamin D. Spending too much time indoors or covering most of your skin can reduce your vitamin D levels.
  • Skin type: People with deeper skin tones need more sun exposure to produce enough vitamin D.
  • Diet: Vitamin D is not naturally found in many foods. Fatty fish, eggs, and fortified foods have small amounts, and breastmilk contains little vitamin D.
  • Health conditions: Certain medical conditions can affect your ability to absorb or produce vitamin D.

How did I get Vitamin D deficiency?

You may have developed vitamin D deficiency due to:

  • Not enough sun exposure: Staying indoors or avoiding the sun for long periods.
  • Skin type: Deeper skin tones make it harder to produce vitamin D from sunlight.
  • Dietary reasons: Not eating enough foods that contain vitamin D.
  • Special circumstances: Pregnancy, breastfeeding, or health conditions affecting absorption.
