Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention group will consume SUPERBA Krill Oil oral capsule 4g once daily for 12 weeks. Each capsule contains 1g of Krill oil, therefore each participant will consume 4 capsules orally.
Adherence to intervention will be monitored by counting the capsules at post-supplementation testing.
