Micronutrient supplementation involves providing essential vitamins and minerals that the body needs in small amounts to function properly. These nutrients, such as vitamin C, iron, and zinc, play crucial roles in various bodily processes, including immune function, energy production, and bone health. People may require supplements if their diet lacks these nutrients or if they have specific health conditions. Supplementation can be beneficial for certain groups, including pregnant women, the elderly, and individuals with dietary restrictions. However, it's important to consult a healthcare professional before starting any supplement regimen, as excessive intake can lead to toxicity and adverse health effects.
