MIAMI — Omega-3 sourced from dietary supplements may be more beneficial to a healthy diet than omega-3 sourced from conventional food, according to a new meta-analysis published in July by the Public Library of Science Genetics.
Across five population-based categories, representing more than 8,800 subjects, the PLoS has found a lower conversion rate from plant omega-3 (abbreviated ALA) to its final derivatives of EPA and DHA. EPA and DHA of omega-3 can be attained directly from dietary omega-3 supplements or through metabolic conversion from ALA, which is mostly found in seeds and plants.
The study found that the higher ratio of ALA in the body corresponded to lower levels of EPA and DHA, suggesting an inefficiency in conversion of ALA to EPA/DHA.
