Caution If You Are Planning to Give Zinc Supplements to Kids

If you are planning to give zinc supplements to your kids, then here are a couple of things you should know

  • May experience side effects like vomiting, nausea, diarrhoea and abdominal pain, fever, and lethargy.
  • High zinc dosage in children has been linked to increased blood cholesterol levels, low levels of HDL, and recurring infections.
  • May interact with other medications such as immunosuppressants, blood pressure drugs, and antibiotics.
  • Children below the age of 18 are not recommended to take over-the-counter zinc supplements unless prescribed by a doctor.
  • Do not use intranasal zinc if you choose to give your child a zinc supplement since it has been associated with the loss of the sense of smell.

Although plant-based foods have zinc, they are in low doses and often not enough to cover the daily recommended intake. You can add zinc in your child’s diet by encouraging them to consume yeast-risen whole-grain pieces of bread and soy-based foods like miso and tempeh to up their intake of this mineral. Zinc-fortified cereals and whole-grains are other options for kids who don’t eat meat and dairy products and are vegetarians or vegans.

Please consult your family doctor or a certified nutritionist before choosing to use a zinc supplement for kids since they may experience the above-mentioned side-effects with an overdose of the mineral.
