Brief Summary

The benefits of a diet enriched with omega-3 fatty acids are multiple and confirmed by several clinical studies. Supplementation with vitamin K, a fat-soluble vitamin, can increase or maintain bone density in postmenopausal women and reduce the risk of fracture. In addition, some studies show that vitamin K may promote the absorption of omega-3 fatty acids. Fish oil, rich in omega-3, is one of the world's favorite forms of omega-3 supplements. However, many people suffer from gastrointestinal discomfort when ingesting fish oil capsules. To minimize these discomforts and improve plasmatic omega-3 bioavailability, Neptune Wellness Solutions has developed a patented formulation of fish oil called MaxSimil®, where omega-3s are in the monoglyceride (MAG) form, a predigested omega-3 form. This formulation has been tested in humans in a double-blind controlled-randomized pharmacokinetic (PK) pilot study with crossover design. PK is defined as a monitoring of omega-3 levels in the blood by frequent blood sampling over a period of 24 hours following the ingestion of a single dose of omega-3. The results obtained showed that MaxSimil® omega-3s are 3 times more absorbed in the blood than the comparison formulation, a source of omega-3 in the ethyl ester (EE) form. Although this first study confirms a greater bioavailability of MaxSimil®, a complementary PK study is necessary to confirm these results and to correct an important methodological bias. In fact, the pilot study did not include a comparator group where omega-3s were in the triglyceride (TG) form, the most widely omega-3 form currently consumed, but rather use an EE form, which have lower bioavailability than TG form. This may therefore have biased the study from the point of view of the comparator and thus give the impression that the comparator had been deliberately chosen to be less bioavailable than the MaxSimil®. In order to confirm the superiority of MaxSimil® (omega-3 MAG form), both in terms of bioavailability and incidence of side effects, the aim of this study is to redo a PK study using this time two comparators, the two main forms of omega-3 currently used (TG and EE forms), as well as a supplementation with vitamin K2 (a form of vitamin K). Our hypothesis is that MaxSimil® will be associated with a better omega-3 bioavailability and a lower incidence of side effects than the other two forms (TG and EE), and possibly also with a better vitamin K bioavailability.

Outcome Measures

Primary Outcomes (4)

  • Determine the bioavailability of omega-3 and vitamin K2 according to the forms ethyl ester (EE), triglycerides (TG) and MaxSimil® (monoglycerides, MAG): Calculating the area under the curve (AUC) 0-24h as the first parameter of the PK

    Plasma omega-3 (DHA and EPA) levels will be measured by gas phase chromatography while plasma vitamin K2 level will be measured by high-performance liquid chromatography (HPLC), each being performed randomly blindly. After GC and HPLC analyzes, area under the curve (AUC) 0-24 hours will be calculated, as the first parameter of the PK. Statistical analyzes will then be performed on this PK parameter.

    Treatments are randomly assigned on days 0, 7 and 14 of the clinical study. GC and HPLC analyzes will be measured on plasma from blood samples collected at time 0, 1, 2, 4, 5, 6, 8, 9, 10, 12 and 24 hours post-treatment.

  • Determine the bioavailability of omega-3 and vitamin K2 according to the forms ethyl ester (EE), triglycerides (TG) and MaxSimil® (monoglycerides, MAG): Calculating the AUC 0-6h (absorption study) as the second parameter of the PK

    Plasma Omega-3 (DHA and EPA) will be measured by gas phase chromatography while plasma vitamin K2 will be measured by high-performance liquid chromatography (HPLC), each being performed randomly blindly. After GC and HPLC analyzes, AUC 0-6 hours (absorption study) will be calculated, as the second parameter of the PK. Statistical analyzes will then be performed on this PK parameter.

    Treatments are randomly assigned on days 0, 7 and 14 of the clinical study. GC and HPLC analyzes will be measured on plasma from blood samples collected at time 0, 1, 2, 4, 5, 6, 8, 9, 10, 12 and 24 hours post-treatment.

  • Determine the bioavailability of omega-3 and vitamin K2 according to the forms ethyl ester (EE), triglycerides (TG) and MaxSimil® (monoglycerides, MAG): Calculating the maximum concentration as the third parameter of the PK

    Plasma Omega-3 (DHA and EPA) will be measured by gas phase chromatography while plasma vitamin K2 will be measured by high-performance liquid chromatography (HPLC), each being performed randomly blindly. After GC and HPLC analyzes, maximum concentration will be calculated, as the third parameter of the PK. Statistical analyzes will then be performed on this PK parameter.

  • Determine the bioavailability of omega-3 and vitamin K2 according to the forms ethyl ester (EE), triglycerides (TG) and MaxSimil® (monoglycerides, MAG): Calculating the time when the maximum concentration is reached, as the fourth parameter of the PK

    Plasma Omega-3 (DHA and EPA) will be measured by gas phase chromatography while plasma vitamin K2 will be measured by high-performance liquid chromatography (HPLC), each being performed randomly blindly. After GC and HPLC analyzes, time when the maximum concentration is reached will be calculated, as the fourth parameter of the PK. Statistical analyzes will then be performed on this PK parameter.

Each participant will perform all three treatments, with a minimum of 6 days between treatments. A questionnaire will document the side effects felt by participants during the omega-3 supplement taking day.

Neither the participant nor the research nurse will know the administration order of the different treatments administered. All plasma samples collected during the research project will be anonymized i.e. it will not be possible to identify the participant by his name since a number will be assigned to him. The code key linking the participant's name to his number will be stored, with access restricted to those designated by the principal investigator. The data file is also protected by a password.
