There are millions of bacteria in your digestive tract known collectively as microflora. Some people use probiotics as a way to promote a good balance of these organisms, and a study published in the journal Lipid Technology suggests omega-3 eicosapentaenoic acid (EPA) might help increase an immune signaling protein that promotes normal gut bacteria.
True Strength Moment: EPA is found in cold water fish like salmon, mackerel and tuna. Previous research published in theJournal of Functional Food found that omega-3 fatty acids encapsulated with probiotic bacteria can have a beneficial synergistic effect. Kind of a mini stack for your stomach.
