This section covers articles about vitamins in general, with particular attention to vitamin D, and explains the functions different vitamins serve in the body. It looks at common signs of deficiency as well as natural sources such as sunlight and specific food groups.
The articles address which vitamins are most often lacking, how a deficiency might show up, and how sufficient intake is typically achieved through diet or, where needed, supplementation. This is useful for readers with a general interest in nutrition topics, though it does not replace individual medical assessment.
