Vitamins and minerals are essential nutrients that our bodies need to function properly. While we can get many of these nutrients through a healthy diet, supplements can help fill any gaps and ensure we're getting all the vitamins and minerals we need. Common vitamins include vitamin C, vitamin D, and B-complex vitamins, which support immune health, bone health, and energy metabolism, respectively. Minerals such as iron, calcium, and magnesium are also important for maintaining healthy bones, muscles, and overall bodily functions. Supplements may also contain other important nutrients like antioxidants, probiotics, and omega-3 fatty acids. It's important to note that vitamin and mineral supplements should not replace a healthy diet, and it's always recommended to consult with a healthcare professional to determine which supplements are right for you.
