I would say that supporting the health of an organ means promoting normal anatomy and physiology. IOW, nothing therapeutic or curative.
Saw Palmetto extract in large enough doses has simi.lar effect as common anti-DHT prescription meds.
Other advances in natural blood sugar regulation are also promising. There is one very interesting new compound that increases glucose sensitivity ONLY in skeletal muscle cells, which has far ranging health effects.
But I also agree, there is also a ton of BS products out there.
