How does the gut microbiome and its metabolic products affect muscle mass, muscle composition, and physical function? In this presentation, I review the evidence, then I present recent data from our group.

In a previous article I wrote about the effect of epicatechin on reducing myostatin, which may increase muscle mass ( Are there any other ways to inhibit myostatin with the goal of increasing muscle mass? 10 grams of essential amino acids have been shown to reduce myostatin levels in skeletal […]

Mice that don’t have myostatin have dramatically increased muscle mass: Myostatin levels increase during aging, a finding that may (at least partially) explain age-related decreases in muscle mass (Basaria and Bhasin 2012). Is there anything that we can do besides strength-training (Snijders et. al 2014) to decrease myostatin levels? To address […]
