However, one report published in integrative medicine research They evaluated various studies claiming that omega-3 fatty acids are an effective treatment for depression and found no link to their findings. the most recent gamma network The study validated this conclusion with their randomized controlled trial, in which more than 18,000 participants contributed – a much higher number compared to other studies that have been conducted.
