Sixty participants who meet the inclusion criteria will be randomly divided into two groups. Participants in FO group will be provided one capsule of fish oil (350mg EPA + 250mg DHA) per day for 6 months. Moreover, participants in FOPE group will be provided one capsule of fish oil (350mg EPA + 250mg DHA) combined with PE (100mg Oligopin) per day for 6 months. A cognitive function evaluation, blood biological analysis and antioxidative status will be carried out at the baseline, 3 th month and the end of the supplementation period. On the other hand, blood fatty acid composition will be measured at the baseline and the end of the supplementation period. All participants will come to laboratory and receive the supplements every month.
