Limited Sun Exposure: Vitamin D is produced in your skin when exposed to sunlight.
Diet Low in Vitamin D Sources: Certain foods are rich in vitamin D. If your diet lacks fatty fish, fish liver oil, egg yolks, or fortified foods like milk and cereals, you might not be getting enough.
Digestive Issues: Crohn's disease, celiac disease, and cystic fibrosis can hinder the intestine's ability to absorb vitamin D from food or supplements.
Obesity: Fat stores can trap vitamin D, making it less available for use. People with obesity may need higher vitamin D doses to reach sufficient levels.
Kidney or Liver Disease: These organs play a crucial role in converting vitamin D to its active form.
Medications: Certain medications, like cholesterol-lowering drugs or seizure medications, can interfere with vitamin D absorption.
Age and Skin Pigmentation: As we age, skin becomes less efficient at producing vitamin D from sunlight.
