This study aims to throw light on the importance of minerals, vitamins and micronutrients in our body. Micronutrients play crucial roles in human nutrition, including the prevention and treatment of various diseases and conditions, as well as the optimization of physical and mental functioning. Understanding micronutrients is critical for anyone seeking to maintain or improve his or her health. Though they are only needed in small amounts, they play important roles in human development and well-being, including the regulation of metabolism, heartbeat, cellular pH, and bone density. Lack of micronutrients can lead to stunted growth in children and increased risk for various diseases in adulthood.
