EDIT: I cancelled my previous order of sulforaphane capsules in favor of buying broccoli sprouts, as there’s no evidence of bioavailable sulforaphane in capsule or pill form that I’ve seen. Apparently an enzyme called myrosinase that’s required to convert glucoraphanan into sulforaphane, which is released only by chewing the actual sprout.
I also came across a study comparing the levels of DHT in people eating alfalfa vs broccoli sprouts, and comparing both to baseline.
While the final results suggested broccoli sprouts didn’t significantly lower DHT, in the Discussion section the authors state "… we could not exclude the influence of alcohol. Based on our hypothesis, SFN induces 3α-HSDs in the liver, and these enzymes subsequently decompose DHT. These enzymes are also induced by alcohol via the Nrf2 pathway ; therefore, participants who habitually drink alcohol might have limited ability to induce these enzymes. In fact, plasma levels of DHT tended to decrease with broccoli sprouts intake, with the exception of participants who appeared to show alcohol-associated impacts on liver function (γ-GTP < 50 IU/L and ALP < 260 IU/L) (S1 Table)."
While Ozeph tries the liposomal form, which I’d still consider a worthwhile trial, I’ll buy a few boxes of broccoli sprouts and begin by eating the same amount (50 g) that the participants in this study did. At some point I intend to eat an entire container a day. What’s great about this is that I can buy these at the supermarket down the street, and I can begin tomorrow.
