Abstract: The postpartum period places significant nutritional demands on mothers, particularly during lactation. Iron and vitamin D are two essential micronutrients whose deficiencies are commonly observed in breastfeeding women, often with serious health implications. This review examines the dual challenge of iron and vitamin D deficiencies among lactating mothers, focusing on their prevalence, underlying causes, health impacts, and current management practices. Iron deficiency, frequently stemming from childbirth-related blood loss and inadequate dietary intake, can result in anemia, fatigue, reduced cognitive performance, and weakened immunity. At the same time, vitamin D deficiency, often due to low sun exposure and insufficient intake, affects calcium metabolism, bone health, and immune function. The simultaneous occurrence of both deficiencies may amplify negative health effects, especially in low-resource settings where access to proper nutrition and medical care is limited. Addressing these deficiencies is crucial for safeguarding maternal health and supporting infant growth and development. The paper concludes by emphasizing the need for continued research and stronger health during lactation and micronutrient deficiency.

Keywords: iron, vitamin D, maternal behavior.
