The Linus Pauling Institute's Micronutrient Information Center (MIC) is a source for scientifically accurate information on the functions and health effects of all micronutrients (vitamins and nutritionally essential minerals); other nutrients like choline and essential fatty acids; dietary factors, including many phytochemicals (non-nutritive plant chemicals that may affect health); and some food and beverages, including tea, coffee, and alcohol. All of the nutrients and dietary factors included in the MIC may be obtained from the diet, and many are also available as dietary supplements; dietary and supplemental sources are discussed in each article.

Human research is emphasized in the MIC, although cell culture or animal studies may be mentioned when human studies are lacking. Most MIC articles have summaries at the beginning and include the following subsections: Function or Biological Activities, Metabolism and Bioavailability, Deficiency, The RDA or AI (for males and females of various age groups), Disease Prevention, Disease Treatment, Sources (food and supplements), and Safety (toxicity and drug or nutrient interactions). For the micronutrients (vitamins and essential minerals), the Linus Pauling Institute provides a daily intake recommendation.

For each article, Ph.D. nutrition scientists critically review and synthesize basic, clinical, and epidemiological studies in the peer-reviewed literature and provide references throughout. Each article is then additionally reviewed by an expert in the field; the names of the authors and reviewers are listed at the bottom of each article. This multiple review process minimizes bias and presents objective information.
