Impact of 2.0g Daily of MAG-EPA on the AA/EPA Ratio and Inflammation Biomarkers in a Healthy Population Aged of 50+.

According to scientific literature, oils containing omega-3 fatty acids may decrease certain risk factors for cardiovascular disease such as blood pressure, blood level of triglycerides (TGs) and cholesterol. The omega-3 index (amount of EPA + DHA in the blood) is a recognized biomarker for assessing risk factors for cardiovascular disease. Its optimal value is 8% compared to the Canadian population average of only 4.5%. The scientific literature contains several good studies on omega-3 fatty acids, however, it is difficult to compare dose-response relationships between studies since formulations are not similar and markers of exposure to treatment are not standardized. The AA/EPA ratio, combined with the omega-3 index, is a good way to monitor the increase in omega-3 levels in the blood, but especially to determine the inflammatory status of a patient. Indeed, eicosapentaenoic acid (EPA) is a fatty acid with inflammation-resolving properties, while arachidonic acid (AA) is a pro-inflammatory agent. A high AA/EPA ratio therefore indicates a high inflammatory status while a low ratio indicates a better balance between active inflammation and its resolution. Moreover, it was published in 2018 that a AA/EPA ratio of around 3 was directly associated with a 25% reduction in the relative risk of cardiovascular disease. Therefore, the investigator wants to determine the minimum MAG-EPA dose needed to achieve an AA/EPA ratio equivalent to 4g of EPA in the form of ethyl ester (EE-EPA). It is reasonable to estimate that 2g of MAG-EPA should be sufficient to produce an average AA/EPA ratio around 3.1.

About this study

This pilot study aims to determine the average value of the ratio of arachidonic to eicosapentaenoic acids (AA/EPA) in a population aged 50 and over without any particular medical condition when supplemented with 2g per day of MAG-EPA for 12 weeks.

1.1 Main objectives

  • To recruit a population of 30 subjects aged 50 and over without any particular medical condition in order to administer 2.0g of MAG-EPA per day for 12 weeks.
  • By measuring the omega-3 index level of all subjects before starting the study and thereafter every 6 weeks over a total period of 12 weeks, the investigator will analyse the individual levels of arachidonic acids and eicosapentaenoic acids to establish the AA/EPA ratio at each visit.
  • The initial AA/EPA ratio will be compared to that obtained after 12 weeks of MAG-EPA supplementation. The results of the present study will be compared to those obtained by daily supplementation with 4.0g of EE-EPA over a similar period of time (taken from the scientific literature) to determine whether MAG-EPA meets the statistical criteria for non- inferiority in terms of response to the AA/EPA ratio.

1.2 Secondary objectives

  • Analyze markers of inflammation such as CRP and PSA (in men only) as well as COX-2 activity before starting the study and thereafter every 6 weeks for a total period of 12 weeks in order to identify the best clinical markers of response to MAG-EPA in the context of the treatment of inflammation.
  • Analyze the lipid profile, before starting the study and thereafter every 6 weeks over a total period of 12 weeks in order to better characterize the effects of MAG-EPA supplementation on this clinical parameter.
  • Determine the proportion of participants who achieve an omega-3 index of at least 8%.
  • Characterize the effects of MAG-EPA supplementation on the proportion of senescent white blood cells, on the omega-6/omega-3 ratio as well as on the subject's blood trans fat content.

Treatment and study plan

Eicosapentaenoic acid monoglycerid (MAG-EPA)

Other

MAG-EPA is an omega-3 fatty acid classified in canada as a Natural Health Product (NHP). The NHP is approuved under the Natural Health Product number (NPN # 80050187).

Primary outcomes

  1. Fatty acids profile analysis

    Time frame: 12 weeks

    The individual content of all fatty acids present in humans will be analysed for each subject on red blood cells obtained by blood sampling after 6 and 12 weeks of supplementation with eicosapentaenoic acid monoglycerides (MAG-EPA). With the individual fatty acid contents obtained for each timepoint, it will be possible to calculate an omega-3 index (% of omega-3, EPA + DHA, on total fatty acids), the total omega-6/omega-3 ratio and finally, the ratio of arachidonic acids to eicosapentaenoic acids (AA/EPA).

Secondary outcomes

  1. Research of clinical biomarkers for inflammation.

    Time frame: 12 weeks

    For each timepoint (0, 6 and 12 weeks), PSA (for men only) and CRP will be analysed through the health services laboratories. The activity of the COX-2 protein will also be analysed in Dr Fortin's research laboratory. The results at 6 and 12 weeks will be compared to the baseline analysis to evaluate the potential in resolution of inflammation when subjects are supplemented with 2.0g daily of MAG-EPA.

  2. Proportion of subjects with a 8% or higher omega-3 index after 12 weeks of supplementation

    Time frame: 12 weeks

    The omega-3 index will be analysed for all subjects included in the study after 6 and 12 weeks of supplementation with 2.0g of MAG-EPA. The proportion of subjects with an omega-3 index equal or higher to 8% will be calculated at this dose for the 12 weeks timepoint.

  3. Impact of supplementation on proportion of senescent white blood cells.

    Time frame: 12 weeks

    At each study visit (week 0, 6 and 12), a whole blood sample will be sent to the laboratory of Dr Fortin for a flow cytometry analysis. The proportion of senescent white blood cells at last visit will be compared to the proportion obtained at baseline.

  4. Comparison of pre and post-dose Lipid profile.

    Time frame: 12 weeks

    At each study visit (week 0, 6 and 12), a whole blood sample will be sent to the health services laboratory for a lipid profile analysis. The results at last visit will be compared to those obtained at baseline and week 6 to detect any change caused by supplementation.

  5. Obsevation and research of any adverse events

    Time frame: 16 weeks

    Subjects will be questionned about any changes in their health status at each study visit (week 0, week 6 and week 12). A telephone follow-up will be done halfway between visits (week 3 and week 9).They will also be instructed to note and report any change in their health status between follow-ups. For each adverse event, the following will be noted: start date, time and severity; end date, time, maximal severity and outcome; seriousness, causal relationship to study drug and expectedness.
