Brief summary

This study is designed to compare the incremental area under the curve from 0 to 24h (iAUC0-24h) of plasma levels of n-3 fatty acids (sum of total and free eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) after ingestion of an emulsified product and a non-emulsified reference control of free flowing cod liver oil at the lowest appropriate dose that is practically acceptable, and as near as possible to the test products' recommended daily dose.

Detailed description

Many dietary lipids are in the form of triglycerides, ethyl esters or phospholipids. During digestion these lipids are subject to hydrolysis, in particular by pancreatic triglyceride lipase. To facilitate the action of the enzyme, lipids are emulsified by the action of bile salts. By increasing the surface area of the fat globules, emulsification increases access to the lipids by pancreatic triglyceride lipase. This study is designed to compare iAUC0-24h of plasma levels of n-3 fatty acids (sum of total and free EPA and DHA) after ingestion of an emulsified product and a non-emulsified reference control of free flowing cod liver oil at the lowest appropriate dose that is practically acceptable, and as near as possible to the test products' recommended daily dose.

Incremental Area Under the Curve to 24 Hours (h) (iAUC0-24h) of the Sum of Plasma Total and Free n-3 Fatty Acids (Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA)Baseline and up to Day 2The AUC was calculated using the trapezoidal method and using nominal time points from 0, 2, 4, 6, 8, 10, 12 and 24 h respectively. The AUC was divided by the total duration to represent a weighted mean incremental change over time. Higher values of AUC demonstrate better rate of absorption over time than lower values.

Outcome results

Primary

Incremental Area Under the Curve to 24 Hours (h) (iAUC0-24h) of the Sum of Plasma Total and Free n-3 Fatty Acids (Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA)

The AUC was calculated using the trapezoidal method and using nominal time points from 0, 2, 4, 6, 8, 10, 12 and 24 h respectively. The AUC was divided by the total duration to represent a weighted mean incremental change over time. Higher values of AUC demonstrate better rate of absorption over time than lower values.

Time frame: Baseline and up to Day 2

Population: Per protocol (PP) population (N=47) was the primary population of analysis defined as all participants in the safety population who have at least one post-baseline assessment of efficacy considered unaffected by protocol violations. From the PP population, 3 participants were not analysed in test group and 2 in control group, due to missing data.
