The energy we use every day to move, think and function comes from the complex process of metabolism, all the cellular reactions that convert food and oxygen into energy and into the building blocks of life. Balanced intake of key nutrients supports the thousands of metabolism-related functions within the body. Catabolic reactions are those that cause the breakdown of large molecules into smaller molecules, releasing energy, while anabolic reactions use energy, as in the formation of proteins from amino acids.
 
When vitamins are absorbed by the body they are often modified to function as coenzymes which support metabolism. B vitamins are key contributors to energy production and storage.
 
The whole family of B vitamins, all 8 of them, are health essentials. Every body needs them. The Bs help maintain muscle and skin health, support immunity, prevent anemia and reduce the risk of cardiovascular disease. Bs are known as the stress and mood vitamins as they reduce symptoms of anxiety and support the nervous system.
 
The B vitamins:

•    Thiamine, B1    
•    Riboflavin, B2
•    Niacin, B3
•    Pantothenic acid, B5
•    Pyridoxine and Pyridoxamine, B6           
•    Biotin, B7, also called vitamin H
•    Folic Acid, also called B9
•    Cobalamin, B12

Folic acid is important for women of child-bearing age as it helps reduce the risk of certain birth defects, and sublingual B12 provides nervous system support and improves sleep.
