For years, most of us in either the life extensionist camp or the physique enhancement camp have touted saw palmetto extract as a weapon against prostate growth. Saw palmetto either blocked DHT from binding to receptor sites, or it somehow limited 5-alpha-reductase (the enzyme responsible for turning T into E) activity.
Trouble is, the largest review of the subject ever undertaken found that neither of the mechanisms "has ever been demonstrated convincingly to be operative in vivo at therapeutic doses."
What they did find, however, was that the substance had some value in treating patients with lower urinary tract symptoms that suggested prostatic obstruction. That means that saw palmetto might just allow men with BPH to pee easier, while not directly affecting the prostate’s size in any way.
Even if saw palmetto is, at some point, vindicated, it doesn’t address what may turn out to be the true problem : estrogen.
