What minimum level of I.U. for vitamin A fortification ensures adequate nutritional value in milk?

Fortifying milk with vitamin A is essential for enhancing its nutritional value, particularly in preventing deficiencies that can lead to various health issues. The recommended minimum level of 2000 International Units (I.U.) of vitamin A ensures that the milk provides an effective source of this vital nutrient.

At this level, the fortification is sufficient to help meet the dietary requirements of populations, especially in regions where vitamin A deficiency is prevalent. The body needs vitamin A for several critical functions, including vision, immune function, and skin health. By establishing 2000 I.U. as a minimum standard, it provides a safety net that helps to promote overall public health and nutrition.

Higher levels of fortification, such as 3000 or 4000 I.U., may be used in some cases or specific populations, but 2000 I.U. is generally recognized as the adequate fortification level for most consumers, balancing the need for nutritional adequacy with the risk of excessive intake.
