Saw Palmetto Benefits Explained: What Research Shows (2025)

Saw palmetto, a small palm tree existing in the southeastern part of America, has been used all through the historic period due to presumed health benefits. This herbal plant, known for its pointed leaves and blackberry-like fruits, has become increasingly popular as a natural remedy.

Here are some of the facts you will learn from this article; the advantages of saw palmetto, its applications, as well as crucial things to consider when using saw palmetto supplements.

What is Saw Palmetto?

Saw palmetto (Serenoa repens) is a shrub-like palm that too grows best in warm regions of the United States of America, Florida in particular. Its berries contain useful chemicals that have been applied using traditional knowledge of Native Americans for different illnesses.

Nowadays, these berries have finally found their place in the arsenal of folk remedies, although for quite a different purpose: to maintain the health of the prostate gland and decrease inflammation.

How Does Saw Palmetto Work?

Saw palmetto's effects come from a unique blend of natural compounds, primarily found in its berries. These active ingredients support a range of potential health benefits, particularly for hormone balance and inflammation.

Among the standout components are:

Phytosterols – Plant-based molecules that may influence hormone activity by interacting with androgen receptors, including those affected by testosterone.

Flavonoids – Known for their antioxidant and anti-inflammatory properties, these compounds help shield your cells from oxidative stress and may ease inflammation.

Fatty Acids – Saw palmetto contains beneficial fatty acids such as caprylic, lauric, palmitic, and oleic acids. These contribute to reducing inflammation and may also assist in promoting healthy nerve signals.

Saw Palmetto Benefits for Men

Improve Urinary Tract Function

Saw palmetto extract (SPE) has been studied for its potential to alleviate lower urinary tract symptoms (LUTS), particularly in individuals with benign prostatic hyperplasia (BPH).

Some research suggests that SPE may improve urinary symptoms by affecting pharmacological receptors in the lower urinary tract.

Support Prostate Health

Saw palmetto is commonly used to treat symptoms of benign prostatic hyperplasia (BPH). However, the studies and reviews have found it to be no more effective than a placebo in treating urinary symptoms related to BPH.

Help Regulate Testosterone Levels

Saw palmetto may influence testosterone levels by inhibiting 5-alpha reductase, the enzyme responsible for converting testosterone into dihydrotestosterone (DHT).

By reducing DHT levels, saw palmetto could help maintain higher testosterone levels in the body, potentially benefiting conditions linked to hormonal imbalances.

Dr. Robert Applebaum

According to Dr. Robert Applebaum, a plastic surgeon in Beverly Hills, saw palmetto can stabilize testosterone levels by reducing the activity of 5-alpha reductase, which is an enzyme that converts the hormone into DHT. In addition, it can also aid by decreasing the uptake of DHT by reducing its ability to bind with androgen receptors. So while the jury is still out, there is some attractive data on its ability to help with testosterone levels.

Prevents Hair Loss

Saw palmetto has shown promise in reducing hair loss, particularly in androgenetic alopecia. It is believed to inhibit the 5-alpha reductase enzyme, thereby reducing DHT levels, which are associated with hair follicle shrinkage.

Some studies have reported improvements in hair density and quality with saw palmetto supplementation.

Helps Reduce Inflammation

Saw palmetto exhibits anti-inflammatory properties, which may contribute to its therapeutic effects. Research indicates that it can downregulate pro-inflammatory cytokines like IL-6 and IL-17, potentially reducing inflammation in conditions such as BPH.

Libido and Fertility

Traditionally, saw palmetto has been used to enhance sexual vigor and increase sperm production. While historical use suggests benefits for libido and fertility, more rigorous scientific studies are needed to confirm these effects.

Anti-Cancer Effects

In vitro studies have found that saw palmetto inhibits the growth of prostatic cancer cells and may induce apoptosis. However, more clinical research is necessary to determine its effectiveness in reducing prostate cancer risk in humans.

Helps With Chronic Pelvic Pain

Saw palmetto extract has been studied for its potential to alleviate symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). While some studies suggest benefits, results are mixed, and further research is needed to establish its efficacy in this context.

Saw Palmetto Benefits for Women

Generally, saw palmetto supplements are taken by males; however, females can receive some gain from the plant since this substance may regulate hormones.

Similar to men, saw palmetto can benefit women health by inhibiting testosterone conversion to DHT and modulating prolactin levels. This may help address PCOS symptoms like irregular periods, excess facial hair, and fertility issues.

For post-menopausal women, the extract may reduce hot flashes, mood swings, and unwanted facial hair caused by elevated DHT levels.

Saw palmetto may also combat female pattern hair loss by blocking 5-alpha reductase enzyme activity, with topical application showing improved hair density.

The extract's antioxidant compounds provide skin benefits through reduced inflammation and acne prevention, while research demonstrates urinary health improvements, including reduced daytime urination frequency and better bladder function in women with age-related incontinence.
