Vitamins for Children’s Growth: A Parent’s Guide to Nutrition and Healthy Growth
Many parents worry when their child looks shorter than classmates and start searching for “vitamins to increase height in children” or “zinc for kids’ height”. This guide explains how children grow, which vitamins and minerals they really need by age, when a supplement helps, and when to see a doctor.
How do children grow?
Children grow very fast in the first year, then growth gradually slows. From age 3 until puberty, most children grow about 5 to 6 cm a year. What matters to a doctor is not a child’s height on one day but their growth trajectory on the growth chart over time.
Daily needs by age
| Nutrient | 1–3 years | 4–8 years | 9–13 years |
|---|---|---|---|
| Vitamin D | 600 IU | 600 IU | 600 IU |
| Calcium | 700 mg | 1,000 mg | 1,300 mg |
| Zinc | 3 mg | 5 mg | 8 mg |
| Iron | 7 mg | 10 mg | 8 mg |

The most important nutrients for a child’s growth
Vitamin D and calcium
The foundation of bone building. Children in the Gulf spend long hours in air-conditioned homes and schools, so vitamin D deficiency is common. Milk, yoghurt and cheese are among the best sources of calcium.
Zinc
Zinc contributes to normal protein synthesis and cell division. Studies show that giving zinc to children who are deficient can improve their growth; a child who is not deficient will not gain height from extra zinc. Sources: meat, chicken, eggs, legumes, and ground nuts for young children.
Iron
Iron deficiency causes anaemia, tiredness and poor appetite, and can affect growth and concentration. Meat, lentils and leafy greens with citrus are good sources.
Protein and energy
A child who does not get enough calories and protein will not grow well, however many vitamins they take. Regular meals and healthy snacks matter more than any supplement.
Does my child need a supplement?
- If your child eats a varied diet and grows steadily along their curve, food plus vitamin D when needed is usually enough.
- If they are a very picky eater, do not drink milk, or blood tests show a deficiency, they may need an age-appropriate supplement chosen with a doctor or pharmacist.
- Do not give children supplements made for adults or teenagers, and never exceed the label dose.
Important: Nutrond Numotam is for ages 11 and up, not for younger children. For children under 11, choose products designed for their age and talk to a doctor.
When should you see a doctor?
- If your child is much shorter than peers and than expected from the parents’ heights.
- If their height has stalled, or they grow less than 4 cm a year after age 3.
- If there are symptoms such as constant tiredness, repeated stomach pain and diarrhoea, or a very poor appetite.
The doctor may order simple tests or a hand X-ray to estimate bone age. Many cases turn out to be a normal growth delay, and the child catches up with peers later.

If you are worried about your child’s growth, talk to a paediatrician or an endocrinologist. Food supplements are not medicines and do not replace a balanced diet.
