a friend somehow knew that curcumin could inhibit 5-alpha reductase. It converts to testosterone to DHT, as you pointed out.
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
Curcumins, certain curcuminoids, depending on the structure, will inhibit the enzyme called 5-alpha-reductase that converts testosterone to DHT. - Turmeric? - Yeah. Turmeric. Black pepper extract. So it's used often to increase bioavailability. It's also called BioPerine. It's also a 5-alpha-reductase inhibitor.
So a lot of it is put with black pepper fruit extract, which is also known as bioperine, which is actually also a 5-alpha reductase inhibitor and it affects liver cytochrome. And so many supplement companies put this black pepper fruit extract-- bioperine-- in almost everything.
Perhaps the only thing on that list that makes logical sense with respect to the biochemistry is that curcumin is known to, in some people, be a potent inhibitor of 5-alpha reductase and DHD so much so that I can personally say for me I once took curcumin, turmeric, it's also called in high dosage.
Yeah, turmeric, black pepper extract.
