Tiamin And Folic Acid

Thiamin (vitamin B1) and folic acid (vitamin B9) are essential B vitamins. Thiamin is naturally found in whole grains, pork, and legumes. Folic acid is the synthetic form of folate, which occurs naturally in leafy green vegetables, fruits, and beans. Both are often added to foods to increase their nutritional value.

These vitamins are added to foods, primarily grain products like flours, cereals, and baked goods, to prevent deficiencies. They are considered nutrients, helping to fortify foods and ensure consumers get adequate amounts of these essential vitamins in their diet.

In the US, thiamin and folic acid are generally recognized as safe (GRAS) when used as nutrients. The FDA permits their addition to foods. International bodies like JECFA have evaluated these vitamins. At typical intake levels from fortified foods and supplements, they are considered safe and beneficial for public health, particularly in preventing birth defects associated with folate deficiency.
