Foods to help with vitamin D deficiency

Vitamin D helps the body absorb calcium and supports bones and muscles. It is found naturally in a limited range of foods, so low levels may reflect diet, limited sunlight exposure, absorption problems, or another health factor. Fatigue, generalised weakness, joint pain, and low mood have many possible causes and do not confirm deficiency on their own.

Choose oily fish such as salmon, sardines, or mackerel when suitable for your diet. Eggs and some mushrooms provide vitamin D, while fortified milk, plant drinks, cereals, or spreads can add more if the label confirms fortification. Include calcium-containing foods as advised. Do not take high-dose vitamin D or combine several supplements without checking, because excess can be harmful. A clinician can interpret a blood test and recommend the appropriate replacement plan.

Arrange a medical review if deficiency is suspected, symptoms continue, or you have bone or muscle pain, repeated falls, or weakness affecting daily activities. Seek prompt help for sudden severe weakness, a new fracture after minor force, or confusion. A stress fracture may cause focused pain that worsens with activity and needs assessment.

Do I need a vitamin D test? Which food sources fit my diet and medicines? What dose and duration of supplement would be appropriate, and when should levels be reviewed?
