For control versus finasteride-treated men, the tissue androgen values obtained with needle biopsy specimens were similar-both for absolute values and the percentage of change-to those previously reported using surgically excised volumes of prostatic tissue. The quantification of prostatic androgens by assay of needle biopsies is thus feasible and offers the possibility of serial studies in individual patients. The SPHB-induced suppression of prostatic DHT levels, modest but significant in a randomized trial, lends an element of support to the hypothesis that inhibition of the enzyme 5-alpha reductase is a mechanism of action of this substance.
Similarly, some people have reported a lower sex drive when taking the herb. However extensive studies show that it should actually improve sexual drive by balancing hormones in your body. Although I have never needed to use saw palmetto for this type of problem, it would stand to reason that if it didn't boost sex drive then it would not be used in supplements designed to do just that. The fact that saw palmetto is an active ingredient in many of the most successful sexual health supplements leads me to believe that it does in fact increase sex drive rather than reduce it.
Every woman is unique, so the amount and form of saw palmetto you need won't be the same as for someone else.
As a general guideline, a common dose for men is 320 mg. of extract per day, standardized to at least 85-95% fatty acids with a guaranteed minimum of -% sterols. ("Standardized" means you get the same amount of active ingredients every time). You may decide to start with a somewhat lower dose.
In men, it can be taken for six weeks before any effect is noticed. If improvement is noted, it is recommended that men take it continuously. Since you're trying to reduce DHT like the men are, you could do the same.
As you can imagine, a supplement program can get complicated. Therefore, we recommend you seek guidance from a naturopathic doctor or other qualified health professional.
WARNING: The quality of botanical supplements varies widely. Don't buy any herbal or botanical product unless it has a "standardized" amount of the active component listed on the label. A "standardized" product has a consistent amount of active ingredients from one bottle to the next. If you buy a product that is not standardized, you have no clue as to what you are actually getting and may be wasting your money.
