Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main purpose of this study is to examine whether n-3 PUFA-induced changes in metabolic risk factors are influenced by genetic variations within genes acting as fatty acids sensors.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main purpose of this study is to examine whether n-3 PUFA-induced changes in metabolic risk factors are influenced by genetic variations within genes acting as fatty acids sensors. To do so, the metabolic risk factor response to an n-e PUFA supplementation will be compared in carriers and non-carriers of polymorphism within genes acting as fatty acids sensors.
