The term vitamin is derived from the words vital and amine, because vitamins are required for life and were originally thought to be amines. Although not all vitamins are amines, they are organic compounds required by humans in small amounts from the diet. An organic compound is considered a vitamin if a lack of that compound in the diet results in overt symptoms of deficiency.

The information from the the Linus Pauling Institute's Micronutrient Information Center on vitamins and minerals is now available in a book titled "An Evidence-Based Approach to Vitamins and Minerals." The book can be purchased from the Linus Pauling Institute or Thieme Medical Publishers.
