DHA supplementation in pregnancy and lactation
Czerniak details that the human brain is 14% EPA and DHA by weight. The fetus undergoes rapid brain growth in the second and third trimesters, and DHA is structural and functional: it enables neuron-to-neuron communication. Without sufficient DHA, serotonin production in the CNS drops, potentially affecting mood and cognition. The body’s conversion of plant ALA to DHA is only 1–5%, making direct sources imperative. This protocol aims to prevent neurodevelopmental deficits and support visual system maturation.
DHA incorporates into neuronal phospholipid membranes, increasing fluidity and enabling neurotransmitter receptor function. It directly influences serotonin synthesis pathways in the central nervous system.
