News & Research:
- Pondering Prostate
Problems? - Dr. Weil, 4/28/06 -
"All told, this study shouldn't discourage men with
mild-to-moderate BPH from using saw palmetto. I still recommend taking 160
mg of a standardized extract twice a day; this should help reduce the size
of the gland in about four to six weeks"
Questions Use of Popular Prostate Treatment - ABC News, 2/8/06 -
"At the end of one year, the men taking saw palmetto
showed no significant improvement in their symptoms ... It's possible that
other preparations of saw palmetto might be effective, even though the one
used in this study was not"
- Relieve Common Men’s
Condition with Saw Palmetto Extract - Healthwell Exchange Daily News,
"Comparison trials found its effects to be similar
to those of finasteride and tamsulosin ... however, while some men using the
standard medications experienced sexual dysfunction as a side effect, men
using the herbal extract did not" - See

- Saw Palmetto Extract
Effective in Treating Chronic Prostatitis - Medscape, 4/28/03 -
"Permixon, a compound extracted from the fruit of
the American dwarf palm tree Serona repens, also known as saw palmetto,
appears to improve symptoms of chronic
prostatitis/chronic pelvic pain syndrome ... Seventy-five percent of the
patients who received Permixon had at least mild improvement in symptoms
compared with 20% of the control group. Similarly, 55% of patients who
received Permixon reported moderate or marked improvement compared with 16%
of the control group ... In the control group, PSA
did not differ from baseline. However, the group taking Permixon experienced
median decreases from baseline PSA of 22% after 6 weeks" - See

- Herbal Remedies
Can Aid Prostate Health - WebMD, 2/4/03 -
"One in three men are treated for
BPH with surgery or, more commonly, prescription drugs such as Flomax or
Proscar. But growing research suggests that some symptoms may be treated as
effectively with over-the-counter herbal remedies -- sometimes less
expensively and thus far, with no reported side effects. What's more, some
of these treatments claim they may help prevent prostate cancer, the second
leading cause of cancer death in men"
- Natural Treatment for
Male Pattern Baldness - New Hope Natural Media, 7/3/02 -
"Those with male pattern
baldness may increase hair growth by taking a preparation containing saw
palmetto (Serenoa repens) and beta-sitosterol
... Conventional medicines used to treat male pattern baldness are designed
to block the conversion of testosterone to DHT. Topical application of
minoxidil (Rogaine®) and taking oral finasteride (Propecia®) have been shown
to inhibit this conversion and to increase hair growth, but both medications
have been linked with several adverse side effects, including fast heart
rate, headaches, impotence, and decreased libido ... 400 mg of a
standardized extract of saw palmetto and 100 mg of beta-sitosterol per day
... After about five months, hair growth in 60% of the men taking the herbal
combination had improved compared with their initial evaluation. In
contrast, only 11% of those receiving the placebo improved"
Fatty Acid and Phytosterol
Content of Commercial Saw Palmetto Supplements - Nutrients 2013, 5(9),
3617-3633 - "The variation in the efficacy in these
trials may be a result of differences in the putative active components, fatty
acids and phytosterols, of the saw palmetto supplements ... Liquid saw palmetto
supplements contained significantly higher (p < 0.05) concentrations of total
fatty acids (908.5 mg/g), individual fatty acids, total phytosterols (2.04
mg/g), and individual phytosterols, than the other supplement categories.
Powders contained significantly higher (p < 0.05) concentrations of total fatty
acids than tinctures, which contain negligible amounts of fatty acids (46.3
mg/g) and phytosterols (0.10 mg/g). Our findings suggest that liquid saw
palmetto supplements may be the best choice for individuals who want to take a
saw palmetto supplement with the highest concentrations of both fatty acids and
phytosterols" - Note: See the table. It was a no contest.
According to Nutra USA, Doctor's Best had the highest fatty acid content of
the products tested. See

Extract Enhances Erectile Responses by Inhibition of Phosphodiesterase 5
Activity and Increase in Inducible Nitric Oxide Synthase Messenger Ribonucleic
Acid Expression in Rat and Rabbit Corpus Cavernosum - Urology. 2013 Apr 23 -
"The results suggest that SPE may have potential
application value for the prevention or treatment of erectile dysfunction
through an increase in iNOS mRNA expression and inhibition of PDE5 activity in
corpus cavernosum smooth muscles" - See

Androgen-independent Effects of Serenoa repens Extract (Prostasan®) on Prostatic
Epithelial Cell Proliferation and Inflammation - Phytother Res. 2011 Jun 8 -
"Prostasan® inhibited epidermal growth factor (EGF)
and lipopolysaccharide (LPS) induced proliferation of the prostatic epithelial,
androgen independent cell line PC-3. At effective concentrations of 50 µg/mL,
Prostasan® partly displaced EGF from EGF receptor (EGFR) but fully blocked
EGF-induced cell proliferation of PC-3 cells. Similarly, Prostasan® inhibited
LPS-induced proliferation of PC-3 cells without affecting LPS activation of the
NFĸB pathway via toll-like receptor-4 (TLR-4). Additionally, Prostasan® reduced
the constitutive secretion of monocyte chemotactic protein-1 (MCP-1), the
LPS-induced secretion of IL-12 and inhibited MCP-1 and granulocyte-macrophage
colony-stimulating factor (GM-CSF) production in the presence of LPS on PC-3
cells. Taken together, our results suggest that S. repens extracts, in addition
to other reported effects on BPH development and prostatitis, inhibits
EGF-dependent growth and proinflammatory responses of the prostate epithelial
cells" - See
