August 24/Miami/Drugstore News -- 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.
