Impacto de la suplementación con ácido docosahexaenoico, un ácido graso Omega-3, en individuos durante el embarazo sobre el neurodesarrollo y crecimiento de la descendencia: revisión sistemática y metaanálisis

DHA supplementation significantly increased neonatal birth weight (mean difference [MD] = 72.51 g, 95% CI: 37.55-107.48), whereas no notable improvements were observed in head circumference, gestational age, birth length, or any of the assessed neurodevelopmental outcomes. Overall, the current evidence does not support benefits of prenatal DHA supplementation for neurodevelopmental outcomes or for growth outcomes other than birth weight in the general population. Future research should focus on identifying subgroups that may be responsive to DHA based on genetic, nutritional, or environmental
