Summary

This study looks at how fast healthy adults convert EPA (an omega-3) into DHA, and whether biological sex or a specific gene (ELOVL2) influences this process. Participants take EPA supplements for 12 weeks and give blood samples. The goal is to understand individual differences in omega-3 metabolism, not to treat any disease.
