Effective Prostate Support
Saw palmetto extract is one of the world's leading herbal products for prostate support. Widely-cited clinical studies conducted during the 1980s have clearly established the ability of Saw palmetto extract to produce major improvements in prostate-related urinary function. Saw Palmetto's key active ingredients help to normalize prostate gland structure.
As men pass through and beyond middle age, hormonal changes occur which can impact the prostate gland. Levels of dihydrotestoterone (DHT), a normal metabolite of testosterone, increase. This, plus an increased binding of DHT to nuclear receptors in the prostate cell, results in growth of prostate tissue. This tissue growth takes place in the part of the prostate which surrounds the urethra, the tube for urine excretion. This can constrict the urethra, resulting in urinary disturbances.
Saw palmetto extract has been shown to inhibit 5 alpha-reductase, an enzyme that controls conversion of testosterone to DHT. Saw palmetto extract also blocks the binding of DHT to prostate cells. These mechanisms are believed to account for Saw palmetto extract's positive effect on prostate gland structure.
In clinical studies, Saw palmetto extract has produced measurable improvements in urinary functions and prostate size. Quality of life scores have also improved.
The results with Saw palmetto extract have been duplicated in open trials and controlled, double-blind studies.
Saw palmetto extract is safe and virtually free of side-effects.
Saw palmetto’s effectiveness comes from its content of natural fatty acids and sterols. These include oleic acid, lauric acid, campasterol, stigmasterol, beta-sitosterol and others. The standard of quality for Saw palmetto extract products is a high concentration of fatty acids and sterols, equaling up to 95%.
Historical or Traditional Use
In the early part of the twentieth century, saw palmetto berry tea was commonly recommended by herbalists for a variety of urinary tract ailments in men. Some believed the berry increased sperm production and sex drive in men.
The liposterolic (fat-soluble) extract of saw palmetto provides concentrated amounts of free fatty acids and sterols. One study with a saw palmetto extract suggests that it reduces the amount of dihydrotestosterone (DHT) (an active form of testosterone) binding in the part of the prostate surrounding the urethra (the tube carrying urine from the bladder). Test tube studies also suggest that saw palmetto weakly inhibits the action of 5-alpha-reductase, the enzyme responsible for converting testosterone to DHT. In test tubes, saw palmetto also inhibits the actions of growth factors and inflammatory substances that may contribute to benign prostatic hyperplasia (BPH). Contrary to some opinions, saw palmetto does not have an estrogen-like effect in men’s bodies.
Over the last decade, double-blind clinical trials have proven that 320 mg per day of the liposterolic extract of saw palmetto berries is a safe and effective treatment for the symptoms of BPH. A recent review of studies, published in the Journal of the American Medical Association, concluded that saw palmetto extract was as effective as finasteride (Proscar) in the treatment of BPH. The clinical effectiveness of saw palmetto has been shown in trials lasting six months to three years.
A three-year trial in Germany found that taking 160 mg of saw palmetto extract twice daily reduced nighttime urination in 73% of patients and improved urinary flow rates significantly. In a double-blind trial, 160 mg of saw palmetto extract taken twice daily was found to treat BPH as effectively as finasteride (Proscar) without side effects, such as loss of libido.
Saw palmetto extract has also been combined with a nettle root extract to successfully treat BPH. One trial using a combination of saw palmetto extract (320 mg per day) and nettle root extract (240 mg per day) showed positive actions on symptoms of BPH (e.g. improved urine flow, decreased nighttime urination, etc.) over a one-year treatment period. Another study compared the same combination to finasteride for one year with positive results.
How much is usually taken?
For early-stage BPH, 160 mg per day of liposterolic saw palmetto herbal extract in capsules is taken two times per day. One trial suggested that 320 mg once per day may be equally effective. It may take four to six weeks to see results with BPH. If improvement is noted, the saw palmetto should be used continuously. It is important to work closely with a urologist to determine clinical improvement. Although it has not been tested for efficacy, saw palmetto is occasionally taken as a tea made with 5–6 grams of the powdered dried fruit. Ground, nonstandardized berry preparations (1–2 grams per day) and liquid extracts of whole herb at 5–6 ml per day are also sometimes used but have not been specifically tested.
Are there any side effects or interactions?
No significant side effects have been noted in clinical trials with saw palmetto extracts. However, in rare cases, saw palmetto can cause stomach problems, and one individual who was taking saw palmetto developed severe bleeding during surgery. According to some clinical trials, saw palmetto extract does not appear to interfere with accurate measuring of prostate-specific antigen (PSA)—a marker for prostate cancer. One test tube study found that saw palmetto did not prevent the release of PSA from prostate cells. Saw palmetto is most effective in managing symptoms of BPH but has not been shown to aggressively shrink the size of the prostate. BPH can only be diagnosed by a physician (preferably a urologist). Use of saw palmetto extract for BPH should only occur after a thorough workup and diagnosis by a doctor. There are no proven uses of saw palmetto for women. There is one case report in which the use of saw palmetto was thought to be the cause of pancreatitis in a middle-aged man, although a cause-effect relationship was not conclusively proven.
