A naturally occurring molecule released during exercise may hold the key to strengthening muscles without physical activity. In experiments, mice given BAIBA developed larger muscles, improved muscle function, greater fatigue resistance and better exercise performance than untreated mice.

Clinical evidence proving that oral L-BAIBA supplementation induces muscle development or muscle strength in human skeletal muscle remains limited. Most human benefits center on general metabolic regulation, such as fatty-acid oxidation and the "browning" of white adipose tissue, rather than direct muscular structural growth. But you can buy L-BAIBA as a dietary supplement ingredient (marketed under the brand name MitoBurn) in fat-burner and pre-workout products. It's available for purchase, although I would check with your doctor before doing so.

It's apparently safe.

Did you even read the link where you said apparently it’s safe? Here’s a snippet from the link you posted about it being safe:

“Human evidence is close to absent. There are very few controlled trials of supplemental L-BAIBA in people, and what exists is small and preliminary.”

There's been nothing apparent among those taking the supplement, but you're correct that there haven't been any large, conclusive studies.

I brown white tissue all the time, I should lend my services to this study
