Inclusion criteria
a. Female participants of child-bearing potential (females who are post-menopausal, i.e., when there has been no menstruation for a minimum of 12 months prior to screening, are considered not to be of child-bearing potential), who are not surgically sterilized, must have a negative pregnancy test at screening and be willing to practice one of the following appropriate contraceptive methods until the last visit: i. Sexual abstinence. ii. Oral contraceptives. iii. Trans dermal patches or depot injection of a progestogen drug (starting at least 4 weeks prior to product administration).
iv. Intrauterine device (IUD), intrauterine system (IUS), subdermal implant, or vaginal ring (placed at least 4 weeks prior to product administration).
Contraceptives must be effective before the randomization visit.
Exclusion criteria
A natural triglyceride derived from microalgae with minimum 365 mg DHA, minimum 100 mg EPA, and minimum 520 mg/g DHA + EPA. Participants receive 600mg/d of omega-3 fatty acids from the microalgal oil.
Commercially available fish oil product MEG-3 1812 TG with a minimum 100 mg DHA/capsule, minimum 160 mg EPA/capsule, and minimum 300 mg/g DHA+EPA. Participants receive 600mg/d of omega-3 fatty acids from the fish oil.
The placebo capsules will be a mixture of corn and soybean oils. Participants receive 600mg/d of omega-3 fatty acids from the corn/soy placebo.
A natural triglyceride derived from microalgae with minimum 210 mg DHA, minimum 300 mg EPA, and minimum 510 mg/g DHA + EPA. Participants receive 600mg/d of omega-3 fatty acids from the microalgal oil.
