Vitamin B1, also known as thiamine or thiamin, appears in plant and animal products like whole grains, beef, pork, and potatoes. However, half of the thiamine in American diets comes from fortified foods. Canada requires specific food products to contain added thiamine. Businesses need a trustworthy vitamin B1 supplier to add this nutrient to their products. Count on Brenntag for thiamine from leading global manufacturers.


Vitamin B1 has the chemical formula C12H17N4OS. Synonyms include aneurine and thiamine mononitrate. It has a melting point of 164 degrees Celsius and a molecular weight of 300.805 g/mol. When thiamine decomposes due to high temperature, it breaks down into nitric oxide, sulfur oxide, and chlorine. Thiamine has high stability when stored in a dry and cool environment. While it does not readily oxidize, keeping it away from air and light provides the best results.

As a water-soluble vitamin, vitamin B1 travels through the bloodstream when consumed. Any unused thiamine exits the body through urine, with a small amount stored in the liver. Vitamin B1 has a short half-life. Therefore, humans must have a constant supply of it to have a sufficient intake. Thiamine has a recommended daily allowance ranging from 1.1mg to 1.4mg for adults. It has a tolerable upper intake level of 50mg, but it does not have any known adverse effects when taken in excess.

Uses of Vitamin B1 in the Food Industry

Food manufacturers use vitamin B1 to increase their products' nutritional value. Canada requires thiamine fortification for products like simulated meat. Meanwhile, the United States does not have any requirements. Instead, American food producers add vitamin B1 to products for marketing purposes. Companies that sell items like cereal and beverages promote their use of thiamine. It makes certain products more appealing to customers and allows companies to meet regulations.

Nutraceutical companies in the food industry sell thiamine supplements. In many cases, vitamin B1 appears in multivitamin formulas. B-complex supplements include B vitamins such as thiamine that enhance brain and digestive function. Thiamine enhances supplement formulas for vegetarians using daily multivitamins. It also comes in the form of standalone thiamine supplements. Common types of thiamine included in nutraceuticals include thiamine mononitrate and thiamine hydrochloride.
