In my (cursory) readings on Sulforaphane (and ROS generation) I came across the term "hormesis":
"hormesis is used to describe the apparently paradoxical phenomenon in which a specific compound induces biologically opposite effects depending on its concentration: in particular, there is a stimulatory or beneficial effect at low doses and an inhibitory or toxic effect at higher ones."
This is probably not news for those better versed in biology. Sulforaphane is hormetic. The study says in order to get cytotoxic and antitumor benefits of Sulforaphane, food dietary intake alone may not be sufficient:
"Notably, all the studies dealing with SFR toxicity report that these effects occur at concentrations above 5–10 μM, that is, levels which can be barely maintained through cruciferous diet intake"
So my question is how do we achieve that level of concentration. I'd imagine thru supplements(?). If so, how do you get comfortable with the dosage and the type of supplement? And what to look for in a "good" sulforaphane supplement?
