Nutrient fortification in cereals, bread, and flour. Essential for energy metabolism and cellular function. Prevents pellagra deficiency disease.
Here is what food agencies say.
FDA mandated fortification in enriched grain products. GRAS as nutrient. RDA: 14-16 mg/day. Upper limit: 35 mg/day from supplements. Approved globally.
Here is what research has found.
Essential nutrient with well-established requirements and safety profile. Pharmaceutical doses used to treat high cholesterol. Deficiency causes pellagra.
