Vitamins and minerals are nutrients your body needs to function—they support everything from bone strength to immune response to energy production. Unlike calories, your body can't make most of them, so you get them through food or supplements. This section covers what different vitamins and minerals actually do, which foods contain them, how much you need, and when supplementation makes sense versus getting nutrients from eating.
The articles here answer practical questions: how to read a supplement label, whether you're getting enough of a particular nutrient, what happens if you take too much, how to choose between food and supplement sources, and which combinations work well together. You'll also find information about specific deficiencies, who might need more of certain nutrients, and how to build a routine that fits your diet and lifestyle.
