Micronutrients such as vitamins and minerals play essential roles in supporting overall health. They are vital for various physiological functions including energy production, immune function, and bone health. Micronutrients help the body utilize macronutrients effectively, aiding in metabolism and reducing the risk of chronic diseases. For instance, vitamin D and calcium are crucial for bone strength, while iron is necessary for oxygen transport. A balanced intake of these nutrients is essential for optimal health and wellbeing, reducing the risk of deficiencies that can lead to health complications.
