Vitamin B1, also known as thiamine, enhances circulation effects energy, growth disorders, and learning capacity. Thiamine is necessary for normal muscle tone of the intestines, stomach and heart. It is a coenzyme in the release of the neurotransmitter acetylcholine and is necessary for the conversion of carbohydrates, protein, and fat into glucose and glycogen for energy. It converts excess carbohydrates to fat for storage. Thiamine requirements increase with fever, pregnancy, lactation, exercise and a high-carbohydrate diet. Oral contraceptivies, sulfa drugs and antibiotics may decrease levels in the body. Cyanocobalamin (B-12, Cobalamin) is one of the few "B" vitamins that can actually be stored for any length of time in the body. Responsible for (aids in) energy production from fats and carbohydrates. Cyanocobalamin is a component in the production of amino acids and red blood cells. Riboflavin (B-2) is necessary for glucose to be converted into energy. This vitamin is not stored in the body and must be replenished on a regular basis. Pyridoxine (B-6) is one of the most essential vitamins as well as most widely used (with regards to the body). It affects both mental and physical components of the body. It's also involved in the metabolism of protein and essential fatty acids. Folic Acid (Folate), another in the "brain food" category, is necessary for energy production and red blood cell formation. It's major purpose is in the synthesis of RNA and DNA, where it is vital for healthy cell division and replication.
