Maternal omega-3 fatty acid supplementation on vitamin B12 rich diet improves brain omega-3 fatty acids, neurotrophins and cognition in the Wistar rat offspring.
The consequences of wide spread vegetarianism due to low vitamin B12 on brain development and functioning is gaining importance. However, there are no studies which have evaluated exclusively vitamin B12 supplementation during pregnancy on brain growth. A series of our animal studies have documented adverse effects of maternal micronutrient imbalance on brain neurotrophins and its amelioration by omega-3 fatty acids. Therefore, the present study investigated the effect of maternal supplementation with vitamin B12 alone and B12 plus omega-3 fatty acid on pup brain fatty acids and neurotrophins at birth and 3 mo of age. ⋯ Our results indicate that a combination of omega-3 fatty acid and vitamin B12 enriched diet may exert beneficial effects on synaptic plasticity and cognition, which may prove beneficial for mental health, particularly in preventing neurocognitive disorders.
