The unborn baby solely relies on the mother to provide it with omega-3. In case the food intake of the mother is low, the infant might not get enough to develop well.

- Behavioral and Attention Problems: According to some studies there is a possible relationship between low levels of omega-3 in the pregnancy period and the increased risk of attention or learning problems in later childhood.
- Reduced Immune Resistance: Omega-3 helps to maintain the health of the immune system and a lack of it can make a person susceptible to infections or allergies.
