The dosage of Vitamin D3 for a 7‑year‑old child is not fixed. It depends on the child’s vitamin D levels, diet, sunlight exposure, and overall health. A paediatrician should decide the exact dose and duration after proper assessment to ensure safety and effectiveness.

For a 13‑month‑old child, it is usually recommended to take 400 IU of vitamin D once daily, which equals 0.5 ml of these drops. The exact dose may vary depending on diet, sunlight exposure, and health, so it’s best to follow your paediatrician’s advice.

The most suitable vitamin D supplement for your children, aged 6 and 10 years, depends on several individual factors, including their diet, sun exposure, growth, overall health, and whether they have a confirmed vitamin D deficiency. Because vitamin D requirements vary by age and health status, and excessive intake can be harmful, it is not possible to recommend a specific supplement or dose without proper evaluation. It is recommended to consult a paediatrician, who can assess your children's nutritional needs and advise on the appropriate vitamin D supplement and dosage if needed. In the meantime, encourage a balanced diet that includes vitamin D-rich or fortified foods, regular safe sunlight exposure, and an active lifestyle to help support healthy bone growth and overall well-being.
