2. Regularly consumed omega-3 supplements in the last three months
3. Fish allergy
4. Maternal age at time of delivery less than 18 or more than 40 years
5. Haemostatic or coagulation disease or taking anticoagulants (warfarin, heparin), because of risk of interaction with omega-3

Infants will be excluded if they:
1. Are small for gestational age (less than or equal to third percentile)

- Primary Outcome Measures
Name Time Method Fatty acid composition of the red blood cell membranes and plasma phospholipids of infants will be given as % weight of total fatty acids (qualitative) and in mg/dl (quantitative). There are several fatty acids in the omega-3 series, but the primary outcome will be the difference in the DHA in red cell and plasma phospholipids between the two groups at the 49th day postpartum. Blood samples (0.5 ml) will be obtained at the time of sampling for medical need if matching with our post-natal day 3, 14, 49 and post-conceptional week 37.
- Secondary Outcome Measures
Name Time Method Fatty acid composition of mother?s breast-milk will be measured to document the lipid content and the % DHA in the colostrum (at baseline). At the time of the first sampling, mothers will have been nursing for no more than three days. Then every week, sample of breast-milk will be analysed. In order to avoid day-to-day variations, aliquots (0.5 ml) from each daily sample of breast-milk will be pooled weekly, and the combined milk will be analysed to obtain a more representative breast-milk fatty acid profile of the week. Fatty acid composition of mother red cell, taken at the same dates of the premature baby samplings will be related to breast-milk composition.
