Source Naturals B-1 -- 500 mg - 50 Tablets

Vitamin B-1 is intimately involved in many aspects of nerve health and function. The active coenzyme form of B-1 thiamin pyrophosphate (TPP) is necessary for energy production and is essential for the formation of acetylcholine a major neurotransmitter. Magnesium plays a role in neuromuscular transmission and activity promoting muscle relaxation. A highly processed “junk food” diet excessive alcohol intake and exhaustive exercise may increase the need for B-1.
