Some of these supplements contain major allergens or may have been manufactured in facilities that handle major allergens (such as nuts, soy, dairy, or other common allergens).

Saw palmetto is a palm-like plant native to the Southeastern area of the United States. Other common names of saw palmetto include the American dwarf palm tree and cabbage palm. The saw palmetto supplement is extracted from the berries of the plant.
Native Americans historically used saw palmetto to treat urinary and reproductive problems.
While saw palmetto's exact mechanism of action is not yet known, experts believe it contains compounds that stop the enzyme needed for converting testosterone to dihydrotestosterone (DHT).
DHT is responsible for growing the cells of the prostate gland, which can lead to an enlarged prostate. Saw palmetto also appears to help decrease inflammation.
Most people report that they tolerated saw palmetto well. Mild side effects may include digestive discomfort or headache.
As with all supplements, it’s best to check with your healthcare provider if saw palmetto is safe for you.
Research is mixed on who may benefit from saw palmetto. Several studies indicate these possibilities:
- Helps promote a healthy prostate.
- Decreasing hair loss.
- Promotes urinary tract health.
- Helps to balance hormones.
- Supports overall health.
Men with prostate health concerns
Benign prostate hyperplasia (BPH) occurs when the prostate gland enlarges and restricts urinary outflow. This condition is common in older males.
Because saw palmetto helps decrease the conversion of testosterone to DHT – the enzyme that increases cell growth of the prostate – researchers have studied if it can help BPH.
While few studies have reported positive results, others did not see any improvement.
One 12-week study showed improved BPH symptoms in males who took beta-sitosterol enriched saw palmetto oil capsules.
Another study found that males who took saw palmetto supplements experienced better urine flow, sexual function, and quality of life compared with those in the test who took the placebo.
However, a large epidemiological study found no clinical benefits on the urinary tract related to saw palmetto supplements.
Individuals with hair loss issues
Hair loss is a common problem, particularly in middle age, when hormones tend to fluctuate, or people may be on medications that cause hair loss as a side effect.
While research is still limited, a review of several studies explored the benefits of saw palmetto for hair loss, particularly hair loss due to androgenetic alopecia – a common form of hair loss for both males and females. It is believed that saw palmetto may block the sex hormones responsible for hair loss.
Two studies from this review of research found that men who took saw palmetto supplements noticed an improvement in their hair loss. One study gave participants 50 mg of B-sitosterol and 200 mg of saw palmetto. About 60% of participants saw improvements in their hair compared to only 11% of the control group. The other study compared saw palmetto and finasteride medication. Approximately 68% of participants in the finasteride group experienced hair growth, while 38% in the saw palmetto group experienced new hair growth.
A third study included in the review of research looked at the benefits of topical saw palmetto. They found that 3.3 mL of saw palmetto serum applied for four weeks, and 2 mL lotion for 24 weeks increased the average hair count of men with androgenetic alopecia.
While some research shows promise for saw palmetto helping with hair loss, research is still limited and there is a need for stronger evidence of these effects.
People seeking urinary health support
Problems with the urinary tract, such as difficulty urinating or urinary incontinence, are common among older adults.
While we have already discussed how saw palmetto may help with urinary problems related to BPH, other urinary issues, such as overactive bladder and needing to urinate frequently at night, may also benefit.
One 12-week study found that Japanese females saw improvements in their overactive bladder symptoms while taking saw palmetto.
While that study shows promise, more research is needed on this topic.
Women with Hormonal Imbalances (PCOS)
Research shows that saw palmetto may reduce elevated hormones, including prolactin, which is typically elevated in people with PCOS.
Saw palmetto is hypothesized to help decrease the conversion of testosterone into its active form, which may help PCOS symptoms.
Animal studies have also shown that saw palmetto helps regulate follicle maturation, formation, ovulation, and cyst formation associated with PCOS.
While there is some promise for using saw palmetto for PCOS and other hormone imbalances, research is limited and currently only animal-based.
Athletes looking for natural performance enhancers
Athletes frequently turn to supplements to help enhance their performance. Saw palmetto may contain some beneficial attributes for athletic performance. However, the research is very limited.
Some have thought that due to saw palmetto’s ability to enhance testosterone levels, it may also boost athletic performance.
One study found that supplementing with saw palmetto and pygeum africana increased the concentration of steroid levels in the urine.
Older adults focusing on overall wellness
Older adults often experience the symptoms previously discussed, such as urinary tract problems, BPH, hair loss, and hormonal imbalances.
While some studies show promise in these areas, there are some that show no improvement when taking saw palmetto. These discrepancies make it necessary for more research to confirm its benefits.
If you are experiencing these symptoms, it’s best to seek the advice of your medical provider for an assessment and treatment plan.
Who should not take saw palmetto?
Because saw palmetto may alter hormone levels, it may not be safe for pregnant or nursed people to take.
Most people who took saw palmetto during studies had no side effects. The few who did experience side effects had diarrhea or headache.
Not much is known about saw palmetto’s interaction with medications or other health conditions. Because of this, it is always important to discuss taking saw palmetto with your doctor.
How to pick the right saw palmetto for your health needs
When searching for your saw palmetto supplement, it’s important to know what to look for. Here are some things to keep in mind.
Look for supplements that contain pure, non-GMO saw palmetto, free of unnecessary additives and fillers. If you have certain dietary restrictions, such as being vegan or having an intolerance to certain foods like soy, dairy, or gluten, be sure to check if the supplement is friendly for your needs.
The FDA does not pre-approve supplements for the safety, effectiveness, or validity of their health claims. Because of this, it’s a good idea to choose a supplement made by a company that values the quality of its products and opts to have them tested by a third party.
Clinical trials that evaluated the effectiveness of saw palmetto gave doses between 100-400 mg of saw palmetto once or twice daily. Taking a saw palmetto supplement that falls near this range may be a good idea.
What the research says: the science behind saw palmetto
Here is a highlight of several recent studies involving saw palmetto.
Saw palmetto may help with modest hair regrowth for people with conditions such as Androgenetic alopecia (AGA), female pattern hair loss (FPHL), or telogen effluvium (TE).
One systematic review in 2020 reported that people who took oral or topical saw palmetto saw a 3.4 to 27% increase in hair count, increased hair density in up to 83.3% of patients, 60% improvement in hair quality, and stabilized disease progression for 52% of participants.
A comprehensive review of research on the benefits of saw palmetto for BPH came to the conclusion that saw palmetto taken alone for aiding BPH symptoms offers minimal advantages.
Taking saw palmetto with other plants or herbs to treat BPH also offers little certainty and requires further investigation.
A 2022 study on Japanese women found that saw palmetto extract may help decrease the symptoms of daytime and nighttime urination frequency.
Best saw palmetto supplement: conclusion
