Observing Metabolism of EPA With Consideration of Genetics And Sex

The goal of this clinical study is to learn how fast EPA is converted to other molecules, including DHA, with consideration of biological sex and genetics in healthy humans. The main questions it aims to answer are: * How fast is EPA converted to DHA in blood, and is the conversion rate affected by sex and a specific genotype we previously identified? * How do sex and the specific genotypes affect blood DHA levels and other products of DHA in response to dietary EPA? * How fast does dietary EPA replace blood EPA and other omega-3 fatty acids, and is the rate affected by sex and genotype? Participants will be asked to take EPA supplements for 12 weeks and provide a series of venous blood samples over the study duration.
