The longer answer is that vitamins, especially the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, Vitamin B6, biotin, and folic acid) do contribute to energy metabolism, by helping your body turn carbohydrates, proteins, and fats into utilizable energy.
When it comes to vitamins, each one has a special role to play. For example: Vitamin D in milk helps your bones. Vitamin A in carrots helps you see at night. Vitamin C in oranges helps your body heal if you get a cut. B vitamins in whole grains help your body make energy from food. Vitamins Hang Out in Water and Fat. There are two types of vitamins: fat soluble and water soluble. When you eat foods that contain fat-soluble vitamins, the vitamins are stored in the fat tissues in your body and in your liver. They wait around in your body fat until your body needs them.
