Key points
In short: UK guidance is that children aged six months to five years should have a daily supplement containing vitamins A, C and D, and that children over five should take 10 micrograms (400 IU) of vitamin D daily through autumn and winter. Beyond that, supplements are there to fill gaps rather than replace meals, and school holidays are simply a period when routines and mealtimes become less predictable.
- The NHS position for under-fives: a daily supplement containing vitamins A, C and D is recommended for children aged six months to five years, whether or not they eat well.
- Vitamin D for older children: 10 micrograms (400 IU) daily through autumn and winter, since UK sunlight is not strong enough between October and March.
- Bone growth: vitamin D contributes to the normal growth and development of bone in children. Calcium is needed for the normal growth and development of bone in children.
- Growth: iodine contributes to normal growth in children. Protein is needed for normal growth and development of bone in children.
- Immune function: vitamin A, vitamin C, vitamin D and zinc all contribute to the normal function of the immune system.
- Energy: vitamin C, several B vitamins, magnesium and iron contribute to normal energy-yielding metabolism.
- When a multivitamin makes sense: as a way of covering the gaps when meals are irregular, not as a substitute for them.
- Practical tips for fussy eaters: liquid and drop formats mix into food or drinks, and giving supplements at the same point each day makes them part of the routine rather than a negotiation.
- Always check with a GP or pharmacist:
Summer is full of sunshine and freedom, but all that activity can be draining for little bodies (and minds)!. From irregular routines to ice cream overload, it can be tricky to make sure kids are getting everything they need to stay healthy, happy and energised.
