The Main Sources of Vitamin D

Vitamin D is essential for bones and immunity and plays a vital role in calcium absorption and immune regulation.

Deficiency may cause osteoporosis, fatigue, muscle pain, and weak immunity. Replace it through natural sources or supplements when needed.

The main source, especially direct morning or afternoon exposure.

- Egg yolks

Contain a good amount, preferably prepared healthily.

- Tuna (TUNA)

A fatty fish rich in D and omega-3.

- Salmon

One of the best sources because of high content.

- Cod Liver Oil

Among the richest natural sources, but use under medical supervision.

- Fortified cereal flakes

Some cereals are fortified, suitable for children and adults.

- Fortified milk and yogurt

Help meet daily needs, especially with little sun exposure.

- Fortified orange juice

Added D makes a good option for vegetarians or people with dairy allergy.

- Testing at AlFarabi Medical Labs

25(OH)D testing
