What are Furanosterols?

Anybody know? Thanks!

Um I have never heard of this…
However Sterolins are better absorbed then sterols because it is more soluble (bonded to glucose molecule)
Both stimulate the release of TH1-type helper T-cells, and reduce the synthesis of interleukin-6 (cause of inflamation).
Other then that I have no idea.

Furanosterols are basically a specific class of plant steroids- to be more precise steroidal sapogenins with the furan B ring.


They are believed to be the primary active component in Tribulus (e.g. Tribex) and Fenugreek, promoting testosterone production (and indirectly muscle mass) via stimulation of pituitary gonadotrophins.

Hope this helps. SRS

Thanks for the info!
