...in mice. :/

This is why I tell my gym bros that they should quit all that Celsius garbage and stick to the basics. You should measure your gut health by the quality of your feces (consistency, texture, colour, shape), and then your muscles and rest of your body will thank you. This research is evidence of that. The science is still catching up.

Roseburia inulinivorans probiotic when? Probably add it to the premade protein shakes and mix specific to those building muscle. https://en.wikipedia.org/wiki/Roseburia_inulinivorans

My gym bros gonna be so shocked lol

So Homer Simpson was right in the end. Beer is basically fermented sugar (well, glucose converted to ethanol by yeast, for the most part; though its maltose first, yeast, bacteria etc... prefer glucose and maltose is a disaccharide of glucose: Maltose).

Perhaps there is also a direct correlation between this microbiome and longevity in the so-called "blue zones" of the world like Okinawa, Sardinia etc. We are what we eat.

I need this

It works by converting fibers into butyrate. You should maintain a high fiber diet to promote Roseburia in your gut

Eat some apples and add 10lb to your bench. Nice!

> This opens up the possibility that the bacterium under investigation could be used as a probiotic to help preserve muscle strength during aging Maybe, but it's really hard to control for other variables here. They don't know what's causing this bacteria to diminish over time in older adults in the first place. It could totally just be dietary habits getting worse over time as people let themselves go. Regardless of age, most people already don't eat enough protein and when they do they might not be getting "complete" proteins either (missing amino acids is common with plant-based foods).

Did quick research on how to support the bacteria growth > Dietary modifications that emphasize high-fiber and prebiotic foods and dietary supplements may support the healthy growth of Roseburia [1] > As stated above, a Mediterranean diet is associated with increased Roseburia growth. This diet emphasizes primarily plant-based foods: whole fruits and vegetables, whole grains, legumes, nuts and seeds, olive oil, and fatty fish. The high fiber and resistant starch content of these foods may fuel Roseburia and the other beneficial flora of the human microbiome [1] > Polyphenols are plant compounds abundant in fruits, vegetables, tea, and coffee. Emerging research indicates that polyphenols can enhance Roseburia abundance indirectly by inhibiting harmful bacteria and fostering beneficial ones.

Neisseria gonorrhoeae doesn't even have muscles but it can pull 100,000x its own weight

emanuele-em

Every few months there's a new study showing gut bacteria control yet another thing we thought was "us." Mood, cognition, immune response, and now muscle strength. Starting to wonder what's even left.

Will people really go after Tom Brady's stuff now? xD

Active cultures are available[0] and there is certainly a way to make them available to the gut isn’t there? 0. https://webshop.dsmz.de/en/bacteria/Roseburia-inulinivorans....

Gym bros are going to be eating their own faeces for the gainz.
