Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Ingestion of 5 x 1g krill oil capsules (containing 833 mg EPA + 471 mg DHA) with breakfast once (in the teaching clinic) followed by 1 week washout period, and
Ingestion of 5 x 1g of fish oil capsules (containing 1037mg EPA + 745 mg DHA) with breakfast once (in the teaching clinic) followed by 1 week washout period.
Standardised breakfast (150g mashed potatoes with 600mL water) is provided. The breakfast is mixed with the intervention oil by the researcher before serving to the participants. Therefore adherence ensured.
