Vitamin B1 is essential to proper heart function Every cell in your body needs vitamin B1 to make adenosine triphosphate, or ATP, the body's main energy-carrying molecule. The heart, in particular, has considerable need for vitamin B1 in order to keep up its constant work. Supplementing with vitamin B1 (thiamin) might help treat congestive heart failure by correcting a vitamin B1 deficiency that is caused by the use of some diuretics.
