How Vitamin B1 Works

Benefits of Vitamin B1
Thiamin may be helpful to people with Alzheimer disease. It mimics acetylcholine, a neurotransmitter critical to memory. Alzheimer 's patients who take 3 to 8 g per day of thiamin have better mental function and fewer senility and memory problems. Any older adult with mental impairment may benefit from additional thiamin, too.

People who suffer from epilepsy and take the drug phenytoin may benefit from taking 50 to 100 mg of thiamin every day. In a four-year study, epileptics taking these doses had better mental function and test scores than those who took folate or a placebo.

Because thiamin plays a part in the reactions that supply the body with energy, "stress formula" supplements often tout it as a cure for stress and fatigue. Although thiamin does not provide energy itself, it helps turn the food you eat into energy. If you're marginally low in thiamin, a supplement will help squeeze more energy out of your food. But deficiencies aren't common if you eat a varied diet of whole foods. Take a look at the thiamin values for the foods listed on the next page,

Thiamin can be found in "enriched" foods, although high cooking temperatures can destroy thiamin. Go to the next page to learn which foods are a good source of this nutrient.
