The fortification addresses common deficiencies and supports overall health, while the absence of harmful additives or excessive processing contributes to its high rating.

Key ingredients 5

Iron
Good

Iron fortification helps prevent iron deficiency anemia, a common nutritional concern. It is essential for oxygen transport in the blood and energy metabolism. Fortified iron is bioavailable and effective in improving iron status.

Risks

Excessive iron intake can cause gastrointestinal issues and, in severe cases, toxicity, but this is rare from dietary sources.

Benefits

Supports the production of hemoglobin and myoglobin, crucial for oxygen transport and muscle function.

Niacin (B3)
Good

Niacin is a B vitamin important for energy metabolism and DNA repair. Fortification helps prevent deficiencies, especially in populations with limited dietary variety. It is water-soluble, reducing the risk of toxicity from food sources.

Risks

High doses from supplements can cause flushing and liver damage, but this is not a concern with fortified foods.

Benefits

Supports energy production and maintains healthy skin and nerves.

Thiamin (B1)
Good

Thiamin is essential for carbohydrate metabolism and nerve function. Fortification helps prevent deficiencies, particularly in diets high in refined grains. It is crucial for converting nutrients into energy.

Benefits

Supports energy metabolism and is vital for proper nerve and muscle function.

Calcium Carbonate
Neutral

Standard formulation ingredient — neither beneficial nor harmful at typical use.

Risks

Excessive intake can lead to hypercalcemia, but this is unlikely from fortified foods alone.

Benefits

Helps to meet daily calcium requirements, supporting bone and dental health.

Risks
