A vitamin is an organic substance your body needs to keep working properly. Vitamins are important to health.
Your body needs food and water to stay alive, but it also needs vitamins to work properly. You get some Vitamin D from the sun, and lots of Vitamin C from citrus fruits such as oranges. Without vitamins, your immune system can weaken. Many people take vitamins in pill form to help them stay healthy. The word vitamin — originally vitamine — was coined by scientist Casimir Funk in the early 1900s. He combined vita, Latin for "life," with amine, from amino acids.
