Background/Objectives: Breastfeeding has accompanied women since the beginning of time and, according to anthropological research, naturally ends between the age of 2 and 6. WHO (World Health Organization) recommends exclusive breastfeeding for about the first 6 months, with continued breastfeeding along with introducing appropriate complementary foods for up to 2 years of age or longer. Despite the increasing promotion of breastfeeding, women do not comply with the WHO guidelines and give up exclusive breastfeeding quickly, and long-term breastfeeding mothers still struggle with a lack of understanding in society. Methods: This work aims to expand the knowledge on the composition and antioxidant status of the milk of mothers breastfeeding past 12 months. Results: The basic composition of human milk changes depending on the stage of lactation. In women breastfeeding for more than a year, an increase in fat (p < 0.001) and magnesium (p < 0.001) was observed. A decreased concentration of leptin (p = 0.001), iron (p < 0.001), and iron-reducing capacity (p < 0.001) was also observed compared to milk from the initial stage of lactation. Conclusions: The milk of women breastfeeding for more than 12 months is a valuable food for the baby, maintaining its protection against free radicals and providing adequate nutrients.
