How Vitamins Work

Why are vitamins so important?

Every day of your life, chances are, you think about vitamins. You read about vitamin content on the nutritional label of every food you eat. There are all the TV and radio spots advertising vitamins. You may even take a vitamin pill when you wake up. It all begs the question: What exactly, is a vitamin? A vitamin is a small molecule that your body must have in order to carry out a certain chemical reaction.
The human body is known to need at least 13 different vitamin molecules.

Why take vitamin C?
Your body needs vitamin C. It is a very simple molecule containing six carbon atoms,
eight hydrogen atoms and six oxygen atoms. Your body needs this molecule for several reasons, but most importantly because of collagen. Since collagen is used in everything from skin to blood vessels, you can see how important vitamin C can be.
Without it your blood vessels weaken, your teeth start to fall out, etc.,
and you eventually fall apart and die. All because of one missing molecule.
