Branched Chain Amino Acids, BCAA’s, are a common addition to the diet for bodybuilders and athletes. Here’s a new research study, published this month, that shows BCAA’s help change your gut bacteria. Specifically, the encourage more Bifidobacteria (which boosts immune function but lowers inflammation) and Akkermansia (which helps build lean muscle mass and reduce fat). As there is much research now connecting aging with inflammation, even calling it “inflammaging”, these are both great things. It’s also somewhat of a departure from the thought of using probiotics and prebiotics to modulate the gut bacteria, adding amino acids to our microbiome toolbox!
