Multivitamins provide a wide range of nutrients that are essential for overall health. By filling gaps in the diet where specific vitamins and minerals may be lacking, they support various bodily functions, including immune function, metabolism, and energy production. Additionally, multivitamins can contribute to improved mood and cognitive function, helping to combat fatigue and enhance mental clarity. It's crucial, however, to use multivitamins as a supplement rather than a substitute for a balanced diet rich in whole foods, as they cannot replicate all the benefits of consuming a variety of nutrient-dense foods.
