Saw palmetto, scientifically known as Serenoa repens, is a small palm native to the southeastern United States, particularly Florida. This low-growing plant produces dark berries that have been used for centuries in traditional medicine—especially by Native American tribes—to support urinary and reproductive health. Today, saw palmetto is one of the most popular herbal supplements for men, primarily due to its powerful effects on prostate health and hormone balance.
What sets saw palmetto apart is its ability to offer natural, plant-based support for age-related issues—without the side effects commonly associated with prescription medications. Let’s take a closer look at why this humble palm has earned a respected place in modern herbal medicine.
Supports Prostate Health
The most well-known benefit of saw palmetto is its ability to support prostate function, especially in older men. As men age, the prostate gland can enlarge—a condition known as benign prostatic hyperplasia (BPH)—leading to urinary issues such as frequent nighttime urination, weak flow, or difficulty starting.
Saw palmetto extract helps by inhibiting the enzyme 5-alpha-reductase, which converts testosterone into dihydrotestosterone (DHT). Elevated levels of DHT are believed to contribute to prostate enlargement. By reducing DHT levels, saw palmetto may slow the growth of the prostate, relieve BPH symptoms, and improve urinary flow.
Improves Urinary Tract Function
In addition to supporting the prostate, saw palmetto may help improve overall urinary health in both men and women. It has mild anti-inflammatory and diuretic properties that can help reduce urinary discomfort, support bladder emptying, and decrease inflammation in the urinary tract.
For men dealing with BPH, this can mean fewer bathroom trips at night, improved sleep, and better quality of life. In women, especially post-menopausal women, saw palmetto may help support urinary control and reduce discomfort.
Supports Hormonal Balance in Men
Saw palmetto’s influence on hormone activity doesn’t stop at the prostate. Because it blocks the conversion of testosterone to DHT, it also helps maintain balanced testosterone levels, which play a key role in energy, mood, muscle mass, and libido.
Men experiencing age-related hormonal changes or early symptoms of testosterone decline may use saw palmetto as part of a natural strategy to support overall hormonal wellness—without relying on synthetic hormone therapy.

May Reduce Hair Loss
One lesser-known but increasingly popular benefit of saw palmetto is its potential to combat hair loss, especially in men with androgenetic alopecia (male-pattern baldness). Since DHT is a key factor in hair follicle shrinkage, blocking DHT production with saw palmetto may slow down or reduce hair thinning.
While more research is needed, some men report improved hair thickness or slower hair loss when taking saw palmetto supplements consistently. It’s also found in some shampoos and topical treatments designed for scalp health.
Anti-Inflammatory and Antioxidant Properties
Saw palmetto berries contain powerful plant sterols, flavonoids, and fatty acids that offer anti-inflammatory and antioxidant effects. These compounds help protect the body’s tissues from oxidative damage, reduce inflammation, and support overall immune function.
Chronic inflammation is a contributing factor in many age-related conditions—including heart disease, diabetes, and joint pain—so adding anti-inflammatory herbs like saw palmetto to your routine can be part of a healthy lifestyle strategy.
May Improve Sexual Health
By supporting hormone balance and improving circulation in the pelvic area, saw palmetto may also contribute to improved sexual health, particularly in aging men. While it’s not a replacement for medical treatment of sexual dysfunction, it can offer natural support for libido, stamina, and overall reproductive wellness.
Some studies and anecdotal reports suggest that saw palmetto may also help boost fertility in men, although more clinical research is needed to confirm this benefit.
How to Take Saw Palmetto
Saw palmetto is available in several forms:
- Softgel capsules or tablets: The most common and convenient form
- Liquid extracts or tinctures: Fast-absorbing and easy to adjust dosage
- Powdered form: Can be added to smoothies or teas, though less common
For prostate support, the typical dosage is 160 mg of standardized extract taken twice daily. Always choose high-quality supplements that contain 85–95% fatty acids and sterols, which are the active compounds responsible for its effects.
Safety and Side Effects
Saw palmetto is generally safe for most adults when taken as directed. Side effects are rare and usually mild, including occasional stomach discomfort, headache, or dizziness.
It’s important to avoid saw palmetto during pregnancy or breastfeeding, as it may affect hormone levels. People taking hormone-related medications or blood thinners should consult a doctor before using saw palmetto to avoid interactions.
