B1 is intimately involved in many aspects of nerve health and function. The active co-enzyme 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.

iHerb Customer Reviews
Recommended by my doctor for leg cramps. I cannot tell you enough about this product. Since I have been taking these 3 times a day for quite a while I do not have leg cramps. If on really hot days and I do too much and sweat a lot I will sometimes need to take an extra tablet, and the leg cramps are gone. No sleepless nights walking the floors anymore. I recommend them to anyone I talk to that has leg cramps and cannot get quinine anymore.
I have fibromyalgia and have been testing various possibilities of supplements that are said to help with the fatigue. I have found that taking high dose vitamin b1 has made a marked difference. I take 4 tablets a day, divided throughout the morning, and it took around 3 weeks to clearly notice the improvement.
