Saw palmetto is a natural extract derived from the berries of the Serenoa repens palm, primarily used to manage symptoms of benign prostatic hyperplasia (BPH). It is thought to inhibit the conversion of testosterone to dihydrotestosterone (DHT) and possess anti-inflammatory properties within the prostate. While generally considered safe, common side effects include mild gastrointestinal issues, and less frequently, sexual dysfunction or headaches. Evidence suggests it can be effective in relieving BPH symptoms and improving urinary flow, although study results vary. Standardized extracts containing a defined percentage of fatty acids and sterols are often preferred for consistent results.

Production Process
Saw palmetto extract is derived from the berries of the Serenoa repens palm. The berries are typically harvested, dried, and then extracted using solvents (e.g., supercritical CO2 or ethanol) to isolate the lipophilic compounds, including fatty acids and sterols.

Inside BodyPotential Benefits
This benefit supports prostate health by potentially reducing the risk of BPH and alleviating related urinary symptoms. It may achieve this through anti-inflammatory and antioxidant effects.
Hair loss prevention reduces hair thinning and shedding by improving scalp health, strengthening hair follicles, and addressing hormonal imbalances. This leads to increased hair density, new hair growth, and improved hair appearance.
Saw palmetto is used to reduce prostate enlargement and alleviate urinary issues related to Benign Prostatic Hyperplasia (BPH) by inhibiting DHT production and potentially reducing inflammation in the prostate. It eases symptoms like frequent urination and weak urine stream.
Saw palmetto improves urinary flow by reducing prostate size, which alleviates pressure on the urethra. This results in better urinary flow rate and reduced residual urine volume.
Possible Side Effects
Dizziness is a sensation of lightheadedness, unsteadiness, or vertigo that can arise from multiple causes. It can lead to falls or loss of consciousness in some cases.
Headache is pain in the head ranging from mild to severe, potentially with nausea, light/sound sensitivity, or dizziness. It can be caused by tension, dehydration, stress, or medication side effects, and persistent headaches require medical evaluation.
Gastrointestinal issues include nausea, diarrhea, abdominal discomfort, and vomiting, potentially stemming from altered gut motility, microbiota changes, or irritation. While often mild, persistent symptoms necessitate evaluation, and contributing factors like pre-existing conditions should be considered.
Gastrointestinal upset involves symptoms like nausea, vomiting, diarrhea, constipation, and abdominal pain. These symptoms are typically mild and often resolve on their own.
Saw palmetto use is rarely associated with sexual dysfunction, including decreased libido, erectile dysfunction, and ejaculatory dysfunction. The mechanisms are not fully understood but might involve hormonal pathways or effects on the prostate.
Scientific Evidence
Key studies include trials published in the Journal of the American Medical Association (JAMA) and Cochrane Reviews assessing the efficacy of saw palmetto in treating BPH. Research has explored different extraction methods and dosages, contributing to varying results across studies. Further research is ongoing to better understand the long-term effects and optimal use of saw palmetto.
