Therapeutic Uses

Congestive heart failure (CHF) is a condition in which the pumping ability of the heart declines, and fluid begins to accumulate in the lungs and legs. Standard treatment for CHF includes strong "water pills" called loop diuretics . These drugs, however, deplete the body of B 1 . 1 Since the heart depends on vitamin B 1 for its proper function, this is potentially quite worrisome. Preliminary evidence, including a small double-blind placebo-controlled trial , hints that supplementation with B 1 can improve symptoms. 2 One double-blind study suggests that thiamin taken at a dose of 50 mg daily might enhance mental function . 3 Other potential uses of thiamin have even less scientific support. Observational studies of people with HIV infection suggest (but definitely do not prove) that increased intake of vitamin B 1 might slow progression to AIDS and enhance overall survival rate. 4 Weak and contradictory evidence hints that vitamin B 1 may be helpful for Alzheimer's disease . 5 6 7 8 Vitamin B 1 has also been proposed as a treatment for epilepsy , canker sores , and fibromyalgia , but the evidence for these uses is too preliminary to cite.
