Is Saw Palmetto Good for You?

Expert
Expert

While saw palmetto studies show inconsistent results for BPH relief due to standardization issues, recent research supports its effectiveness alone or with other treatments. It also improves hair quality, density, and count in androgenetic alopecia and telogen effluvium.

Is Saw Palmetto Good for You?

Saw palmetto (Serenoa repens) supplements are commonly used by men to support prostate health, particularly for benign prostatic hyperplasia (BPH) and, in some cases, as a complementary therapy for prostate cancer. While saw palmetto extract (SPE) shows therapeutic potential for alleviating lower urinary tract symptoms (LUTS) linked to BPH, its efficacy is inconsistent, often due to a lack of standardized formulations.


Saw palmetto may also provide modest benefits for hair loss conditions like androgenic alopecia (AGA), though the evidence remains limited. It is generally safe, but its mechanisms, long-term safety, and optimal use require further research. While it offers an alternative for men seeking natural remedies, those with severe or persistent symptoms should consider standard medical treatments.

Traditional treatments for BPH often incur adverse side effects, including sexual dysfunction, which are the primary reasons people seek out natural and alternative remedies for their symptoms of BPH, such as herbal remedies like saw palmetto.

How to Choose Saw Palmetto Supplements - Buying Guide

Here are the points to keep in mind when choosing the best saw palmetto supplement for you.
1

Check the Dosage: 320 MG Daily Is Standard

Expert
Expert

A standard 320 mg dose of saw palmetto significantly reduces overactive bladder symptoms, improving urinary frequency and discomfort.

Check the Dosage: 320 MG Daily Is Standard

The standard dosage for saw palmetto supplements is 320 mg daily, commonly used to support prostate health and manage symptoms of benign prostatic hyperplasia (BPH). This amount is generally effective and safe for most users.


Higher doses do not offer additional benefits. Studies found that increasing the dose to three times the standard had no greater effect on improving urinary symptoms or other BPH outcomes, emphasizing the importance of sticking to the recommended amount.

2

For Reliable Results, Look for Supplements Standardized to Contain at Least 80% Fatty Acids

Expert
Expert
A 2023 study states that fatty acid standardization to ≥ 80% is necessary to meet US Pharmacopeia quality standards for saw palmetto.
For Reliable Results, Look for Supplements Standardized to Contain at Least 80% Fatty Acids

Supplements standardized to contain at least 80% fatty acids are ideal for reliable saw palmetto benefits. These compounds are key to saw palmetto's therapeutic effects, particularly for BPH. Standardization ensures consistent potency and efficacy, providing better results and reducing variability. A clearly labeled percentage of active ingredients indicates that the product has been tested for quality.


Choosing standardized supplements offers greater transparency and reliability, ensuring effectiveness. The hexane extract of Serenoa repens is considered a safe and reliable option for treating BPH symptoms, helping users avoid low-quality, inconsistent products.


Kathy Shattler, MS, RDN

The hexane extract of Serenoa repens, also known as Permixon, is a trusted option for managing BPH symptoms and requires a doctor's prescription.

3

For Maximum Fatty Acids and Phytosterols, Opt for Liquid Supplements or Softgels

Expert
Expert

Saw palmetto's effectiveness depends on its phytosterol and fatty acid content. Liquid extracts, rich in phytosterols and fatty acids, are preferred for their synergistic antioxidant, anti-inflammatory, and 5-α reductase-inhibiting benefits.

For Maximum Fatty Acids and Phytosterols, Opt for Liquid Supplements or Softgels

For maximum effectiveness, liquid saw palmetto supplements or softgels are ideal, as they offer higher concentrations of fatty acids and phytosterols. A U.S. study found that liquid SPE supplements had the highest levels of these compounds, making them the most effective. Softgels, classified as liquids in the study, also ensure better absorption and potency.


Liquid and softgel forms maximize the intake of active ingredients, providing more reliable and potent doses for prostate health and other uses. These solvent-based supplements are currently considered the most effective on the market. Some liquid supplements may be cold-pressed which can still be effective in treating BHP symptoms.

4

Pick Blends With Pumpkin Seed Oil or Nettle Root for Enhanced Prostate Health Support

Expert
Expert

Pumpkin seed oil, zinc, stinging nettle, and saw palmetto combine their anti-inflammatory and antioxidant properties to effectively address BPH symptoms and stimulate hair growth.

Pick Blends With Pumpkin Seed Oil or Nettle Root for Enhanced Prostate Health Support

Saw palmetto supplements with added ingredients like pumpkin seed oil or nettle root can enhance prostate health and address hair loss. These ingredients work together to improve urinary function and support BPH treatment. 


"Nutrient synergy occurs when compounds work together for a greater effect," explains registered dietitian Kathy Shattler, MS, RDN. "For example, Serenoa repens (saw palmetto) and Urtica dioica (stinging nettle) help alleviate BPH symptoms by reducing inflammation and oxidative stress, while their complementary actions support prostate health." Studies also suggest that pumpkin seed oil and saw palmetto are effective for BPH, while nettle root may complement saw palmetto.


For a holistic approach, combining saw palmetto with ingredients like zinc can support hormonal balance and inflammation. A 2007 study found that a combination of saw palmetto and nettle root was more effective than a placebo in reducing BPH symptoms, making these blends a great option for comprehensive health support.

Look for Brands That Undergo Third-Party Testing for Quality and Safety

Expert
Expert
Lower-potency saw palmetto extracts, often used to cut costs, raise concerns about product quality. Third-party testing helps ensure transparency and purity.
Look for Brands That Undergo Third-Party Testing for Quality and Safety

Third-party testing is essential for ensuring the potency and purity of saw palmetto supplements. Independent labs verify that the product contains the correct amount of active ingredients, like fatty acids and plant sterols, and is free from contaminants such as heavy metals and pesticides.


This testing process provides assurance that the supplement is both effective and safe. Choosing brands that undergo third-party testing ensures the product meets quality standards, giving consumers peace of mind.
