Does Saw Palmetto Work

does saw palmetto work

One of the most commonly experienced prostate conditions among aging men is called benign prostate hyperplasia (BPH). This can be a significant disruption in a man’s everyday life, leaving many seeking natural treatments. Saw palmetto is a frequently used herbal therapy for BPH, but what is saw palmetto, and how effective is it?

What is Saw Palmetto?

Saw palmetto is a variety of palm tree (Serenoa repens) that grows in Cuba, the Bahamas, and the Southeastern United States, where it can grow as far as West Texas and Southern California. The berries of the saw palmetto plant, which are dark with a single large seed in the middle, are the part that’s often used to help manage certain prostate conditions. 

Are There Any Benefits to Taking Saw Palmetto?

Saw palmetto was a very common herbal treatment for prostate and urinary health issues between the 1870s and 1950. At this point, it is no longer recognized as a drug in the United States, but it remains used in Europe and is an approved herbal treatment by German Commission E.

As for other saw palmetto benefits, evidence is scarce. While it’s most commonly used for prostate conditions, it’s considered potentially helpful for male pattern baldness. However, the research is still limited in this area. Both of these uses are thought to have to do with saw palmetto’s potential ability to prevent the conversion of testosterone to a more potent form, which is called dihydrotestosterone.

Otherwise, some research suggests that there could be promise in using saw palmetto to help slow the growth of and even kill prostate cancer cells, but the evidence is limited here as well. 

Is Saw Palmetto an Effective Treatment for BPH?

Benign prostate hyperplasia (BPH) is a non-malignant condition in which the prostate gland slowly becomes bigger than normal over time. It affects an estimated 50% of men beyond age 50. 

BPH is considered one of the lower urinary tract symptoms (LUTS), which are conditions that involve the prostate, bladder, and urethra. Common symptoms of BPH can include frequent urination, especially at night, and dribbling after urination.

Does saw palmetto work for BPH? While it has been used as an herbal treatment for BPH for decades, there’s actually no strong evidence in support of its efficacy. Health experts disagree about saw palmetto BPH effectiveness, and if it does help, what mechanism is responsible. Some hypothesize that it helps shrink the enlarged prostate gland or at least prevents it from becoming larger.

In a 2006 study published in the New England Journal of Medicine, 225 men over the age of 49 years with moderate-to-severe symptoms of BPH were given 320 mg of saw palmetto (160 mg twice daily) or a placebo for one year.

At the end of the study, the researchers found that those who received saw palmetto didn’t experience any significantly different results in terms of symptoms or other markers of BPH, compared to the placebo group.

In 2012, a Cochrane review concluded that saw palmetto provides minimal improvement for BPH or other LUTS. 

Fast forward to 2019, and the authors of a review published in Food Science and Biotechnology concluded that saw palmetto extract has therapeutic potential for BPH, but the current evidence is inconsistent and inconclusive. This is partly because there hasn’t been a standardization of the saw palmetto extract used in research for this purpose.

So, does saw palmetto work? Overall, saw palmetto is not considered an effective treatment for BPH at this time. The good news is that there are other natural compounds that have proven to be helpful for this condition such as Beta-Sitosterol.

Beta-Sitosterol vs Saw Palmetto for BPH

When it comes to beta-sitosterol vs saw palmetto for BPH, the more effective compound is beta-sitosterol. 

Beta-sitosterol is a plant fat with a chemical structure similar to cholesterol. It’s been studied for its ability to help lower blood cholesterol levels, as well as to alleviate symptoms of BPH. 

For instance, a 2000 Cochrane review involving 519 men from 4 randomized, placebo-controlled, double-blind trials lasting 4-26 weeks concluded that beta-sitosterols can be used to improve urinary symptoms and flow measures. 

And in a 2000 clinical trial, researchers found that beta-sitosterol treatment was effective for symptomatic benign prostatic hyperplasia and that this was maintained for 18 months following an original 6-month double-blind trial.

That original trial, published in 1997, found that giving 177 patients 130 mg free beta-sitosterol daily for six months was effective for treating BPH symptoms, with significant improvements over those given a placebo instead. No safety concerns from using beta-sitosterol were identified. 

Many other studies have supported the use of beta-sitosterol for BPH symptoms, some of which have even found it to be effective for reducing prostate cancer cell growth. This appears to be even more effective when beta-sitosterol is combined with resveratrol, an antioxidant compound derived from red grapes. 

Overall, beta-sitosterol has proven itself to be a much better investment than saw palmetto for managing frustrating symptoms of BPH.
