"Every mental state is affected by Brain Chemistry, from sleep to euphoria. Supplying ourselves with brain nutrients is an excellent way to enhance and improve our own performance.
The human brain is the master control system of the body. It weighs about 3 pounds -- less than two percent of our body weight. The brain requires 20% of our oxygen and energy supply for the over 100 billion neurons (brain cells).
Blood flow containing oxygen, sugars, vitamins, minerals, amino acids and fatty acids is essential. Interruption of this flow for even fifteen seconds can result in unconsciousness, and in five minutes, death." Big Vitamin Dictionary
