Ensuring a 3-year-old receives adequate nutrition is crucial for healthy growth and development. Zinc, an essential mineral, plays a vital role in immune function, wound healing, and cell growth. This article details zinc needs, deficiency signs, supplementation options, and safety considerations for this age group.

Daily Zinc Requirements
The recommended daily allowance (RDA) of zinc for children aged 1-3 years is 3mg. Most children obtain sufficient zinc through a balanced diet.
