What it is

Niacin, also known as vitamin B3, is an essential nutrient that plays a role in energy production and metabolism. Ferrous sulfate is a common iron salt. Together, they are often used as fortifying agents in food products.

Why it's used

This combination is frequently added to processed foods like pasta dinners, canned soups, and bread crumbs to increase their nutritional value by adding iron and vitamin B3. Manufacturers use it as a nutrient supplement to help consumers meet their daily requirements for these essential vitamins and minerals.

Health notes

Niacin and ferrous sulfate are commonly added to foods as nutrient supplements. The FDA considers niacin to be generally recognized as safe (GRAS) when used as a nutrient. Ferrous sulfate is also permitted for use in food. Excessive iron intake can cause gastrointestinal upset, and the National Academies have established upper intake levels for iron. JECFA has evaluated niacin and set an acceptable daily intake. The long-term effects of consuming fortified foods at typical levels are generally considered safe and beneficial for public health, helping to prevent deficiencies.

Allergen info

Neither niacin nor ferrous sulfate are derived from the nine major allergens. They do not contain gluten.
