Eligibility Criteria

21 Years - 65 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  1. Male or female, 21 to 65 years of age, inclusive.

  4. The subject has no plans to change smoking habits during the study period.
  5. Subject is willing to maintain a stable body weight, current activity level, and dietary habits except for use of the study products as directed.
  6. Subject understands the study procedures and signs forms documenting informed consent to participate in the study and authorization for release of relevant protected health information to the study Investigator.

Exclusion Criteria:

1. Subject has coronary heart disease or a coronary heart disease risk equivalent including any of the following:

  • Diabetes mellitus (or fasting glucose ≥126 mg/dL at visit 1).
  • Clinical signs of atherosclerosis including peripheral arterial disease, abdominal aortic aneurysm, or certain types of carotid artery disease.
  • Presence of multiple risk factors that give a person a greater than 20% chance for developing coronary artery disease within 10 years as determined by the Framingham risk index calculated at visit 1.

    5. Uncontrolled hypertension, defined as resting systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥100 mm Hg at screening.

    6. Use of any lipid-altering drugs, including statins, bile acid sequestrants, cholesterol absorption inhibitors, fibrates, or prescription formulations of niacin within four weeks of visit 1 and throughout the study. 7. Use of EPA/DHA from a drug or supplement within four months of visit 1 and throughout the study period.

    8. Frequent use of any non-study-related EPA/DHA containing enriched foods (such as DHA-enriched eggs) within four months of visit 1 and throughout the study period.

    9. Use of flaxseed, perilla seed, hemp, spirulina, walnut, mustard seed or black currant oil for more than one week duration within four weeks of visit 1 .

    10. Consumption of fatty fish (salmon, herring, mackerel, albacore tuna, or sardines) more than twice per month within four months of visit 1 and throughout the study period.

    11. Use of any dietary supplement known to alter lipid metabolism. 12. Use of any weight-loss medication (prescription or over-the counter) within four weeks prior to visit 1 and throughout the study.

    13. Use of any weight loss supplement or program within four weeks of visit 1 and throughout the study.

    14. Females who are pregnant, planning to be pregnant during the study period, lactating, or women of childbearing potential who are unwilling to commit to the use of a medically approved form of contraception throughout the study period.

    15. History or presence of significant, renal, hepatic, gastrointestinal, pulmonary, biliary, neurological or endocrine disorders.

    16. History or presence of cancer, except for non-melanoma skin cancers . 17. Current or recent history of (within 12 months of visit 1, week -1) or strong potential for alcohol or substance abuse.

    18. Use of any investigational drug within 30 days prior to visit 1. 19. Individual has a condition the Investigator believes would interfere with his or her ability to provide informed consent, comply with the study protocol, which might confound the interpretation of the study results or put the person at undue risk.

    20. Medications and/or supplements known to influence lipid metabolism or body weight are not allowed within four weeks of visit 1. Unstable use of antihypertensive or thyroid medication will also not be permitted.
