Introduction: Little research has explored galactagogue food consumption in China. This study aims to investigate consumption patterns and how they relate to perceived insufficient milk supply and exclusive breastfeeding. Methods: Data were collected from postpartum women in China at six time points: baseline demographic questionnaire before hospital discharge (T0), galactagogue food questionnaire at 1 month postpartum (T1), Hill and Humenick Lactation Scale at 6 weeks postpartum (T2), and breastfeeding practices at 1, 2, 3 and 4 months postpartum (T1, T3, T4, T5). Results: Of 218 participants who completed the galactagogue food questionnaire, 64.68% were consumers. No association was found between galactagogue food consumption and perceived insufficient milk supply. Consumers were less likely to breastfeed exclusively. Discussion: Future research should emphasize a deeper understanding of consumer behaviors and family support in providing professional guidance on postpartum nutrition that considers not only social and cultural experiences but also broader medical aspects.
