Dietary Omega-7 Palmitoleic Acid-Rich Oil on Lipoprotein Metabolism and Satiety in Adults
NCT03372733 · View on ClinicalTrials.gov ↗
Study Summary
Background: Omega-7 fatty acids are found in the oil extracted from certain fish and nuts like macadamia. Palmitoleic acid is one of the most common omega-7 fatty acids. Many studies suggest that this oil is good for heart health. Researchers want to find out more about these potential benefits. Objective: To study how oil enriched with palmitoleic acid (Omega-7 oil) affects metabolism. Eligibility: Healthy adults at least 18 years old with no known history of cardiovascular disease. Subjects not allergic to fish oil and fish products Females that are not pregnant and are not planning a pregnancy during the length of the study Design: Participants will be screened with questions about their health, medical history, and medicines they take. Participants will have 4 visits over 24 weeks. The visits may include: * Blood drawn from a vein in the arm by a needle stick. Sometimes participants will have to fast before the blood draw. * Vital signs (blood pressure, heart rate, and temperature) taken * Body mass index measured * Cardio-Ankle Vascular Index test may be performed. The stiffness of the participant s arteries will be measured by reading blood pressure in the arms and legs and monitoring the heart. * Optional stool samples * Pregnancy test * A short review of participants physical activity and diet * A supply of dietary supplements to take between visits. Participants will take 4 gel capsules a day. Participants will keep a food and exercise journal Compensation will be provided to subjects that complete the study Check your eligibility for this study by clicking here: https://www.surveymonkey.com/r/DietaryOmega

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03372733
The ClinicalTrials.gov registry entry for NCT03372733 describes a study currently listed as recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 110 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Heart, Lung, and Blood Institute (NHLBI), which has 381 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Cardiovascular Disease appearing as the primary indexed condition, and to 2 interventions — of which control olive oil (COO) is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03372733 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
