Key finding: The authors frame fat tissue browning as the route connecting follistatin activity to the cardiometabolic outcomes they discuss.

A 2026 article in the journal Hypertension examined how follistatin driven browning of adipose tissue relates to cardiometabolic health markers.

animal study

Key finding: The effects ran through activin neutralization and AMPK activation, and a standard blood pressure drug used for comparison did not reproduce them.

In an animal study with spontaneously hypertensive rats, researchers reported that follistatin restored the relaxing influence of the fat tissue around blood vessels, alongside lower oxidative stress and browning of that perivascular fat.
