Experts warn against routine long-term vitamin D and calcium supplementation for children

Medical professionals urge parents to rely on individual needs and clinical advice for supplementing children with vitamin D and calcium, emphasising risks of unnecessary long-term use.

Many parents assume vitamin D and calcium should be given for long periods, but doctors say the need is not the same for every child and should depend on age, diet, sun exposure and overall health. Aaj Tak reported that the decision on how much vitamin D a baby needs after birth and for how long it should continue ought to be made on medical advice, not habit.

In infants and very young children, the risk of vitamin D deficiency is higher, particularly among children who are not breastfed. The Aaj Tak report quoted paediatrician Rahul Verma of Yashoda Medicity Hospital as saying that babies from birth to 1 year are commonly advised to take 400 IU of vitamin D daily, with any increase in dose based on clinical examination and blood tests. Johns Hopkins Medicine and the NHS both note that vitamin D helps the body absorb calcium and supports bone and muscle health, while NIAMS says both nutrients are central to strong bones.

Calcium is also important as children grow, but specialists say that does not mean every child needs a tablet. If a child drinks milk regularly, eats yoghurt or includes paneer in the diet, doctors often see no need for extra calcium supplements. The NHS and Johns Hopkins Medicine both stress that calcium is already available from a wide range of foods, and that supplementation should be used carefully to avoid excessive intake.

Verma also warned parents not to continue vitamin D or calcium on their own for long periods, since too much can be harmful. He said warning signs such as repeated bone pain, weakness, muscle problems, slowed growth or signs of poor nutrition should prompt a medical review. The broader advice from Cleveland Clinic, Drugs.com and the NHS is that supplementation should be matched to need, and that balanced diet, physical activity and regular sunlight remain important parts of children’s health.
