Brief summary
The goal of this clinical trial is to compare the uptake of two different omega-3 fatty acid preparations in healthy adults. The main question it aims to answer is whether the two different preparations have the same uptake after single dose supplementation.
Detailed description
Participants will be asked to take capsules of the new phospholipids+ (PL+) omega-3 product (a combination product of krill oil and fish oil) in the morning with a low-fat breakfast. This product contains around 1250 mg eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA). Researchers will compare this group with another group that takes standard fish oil (FO) ethyl esters (EE, with the same amount of EPA+DHA) to see if there are differences in pharmacokinetic parameters, including incremental area under the curve (iAUC), the maximum concentration of (Cmax) and the time it takes for EPA, DHA and EPA+DHA to reach the maximum concentration (Tmax) in plasma.
Interventions
PL+ omega 3 fatty acids is a food supplement that combines krill oil and FO EE. The dose will be around 1250 mg EPA+DHA.
A conventional fish oil food supplement containing EPA and DHA in the EE form. The dose will be 1250 mg EPA+DHA.
