Nutrition Information:

Vitamin B1 (Thiamine)

Thiamine functions as a coenzyme in the conversion of carbohydrates and certain amino acids to provide energy for muscle, brain and nervous tissue.[1,3] Therefore, thiamine could help avoid muscle fatigue and body tiredness, also promote health of the brain and the nervous system. Thiamine deficiency has been associated with chronic alcoholism.[3,4] Consumption of tea and coffee would also increase the requirement for thiamine intake.[4]

Vitamin B6 (Pyridoxine)

Vitamin B6 is required for the proper growth and development of the brain, nerves, skin, and many other parts of the body.[5] The major form of vitamin B6 in the tissues is PLP, a coenzyme for more than 100 enzymes involved in amino acid metabolism, neurotransmitter synthesis and heme biosynthesis.[3] It helps maintain a sufficient supply of hemoglobin. 

Vitamin B12 (Cobalamin)

Vitamin B12 is essential for normal blood formation and neurological function.[3] It participates in methyl conversion and folic acid metabolism, facilitates blood cell and nerve cell metabolism and neurotransmitter synthesis to ensure normal function of the central nervous system.[1,3,7] Some individuals, especially the elderly or people with digestive tract disorders, may be unable to absorb naturally occurring vitamin B12 effectively.[3,7] They may need to take supplements in order to meet their dietary requirement. Supplementation with B12 may improve cerebral and cognitive functions in the elderly.[1]
