Vitamin D3
Vitamin D3 (cholecalciferol) is a fat-soluble vitamin the body produces when exposed to sunlight.
Vitamin D3 is involved in calcium and phosphorus metabolism and in immune system function. Natural sources include fatty fish, egg yolk and fortified products; sun exposure is the main source.
In winter months and for people with less sun exposure, vitamin D3 supplements are often recommended. Tablets, drops and oil-based formulas are available.
The specific dose depends on age, blood level and condition. Testing and a doctor's advice are recommended.
