Saw Palmetto Extract Oil
Also known as: Saw palmetto, Saw palmetto extract, Serenoa serrulata, Palmae, Sabal serrulata, Serenoa repens
Overview
Saw palmetto (Serenoa repens) is a small palm tree native to the southeastern United States, predominantly found in Florida. The medicinal extract is obtained from the dried mature berries of this plant. It is primarily used to manage benign prostatic hyperplasia (BPH) and relieve lower urinary tract symptoms (LUTS) in men. Saw palmetto contains significant amounts of phytosterols, fatty acids, and flavonoids, which are believed to contribute to its therapeutic effects. Comprehensive research including randomized controlled trials and systematic reviews supports saw palmetto's efficacy in urinary health improvement related to BPH, though the quality of studies can vary. Available forms of the supplement include softgel capsules and liquid extracts, making it a convenient option for those seeking natural remedies for urinary tract issues.
Benefits
Saw palmetto is recognized for its positive effects in enhancing urinary tract symptom scores, significantly reducing nocturia, and improving urinary flow in men with BPH. A systematic review illustrated an average reduction in urinary symptoms by -1.41 points and a decrease in nocturia frequency by -0.76 times per evening. Its action is chiefly attributed to the inhibition of the enzyme 5α-reductase, leading to lowered dihydrotestosterone (DHT) levels implicated in prostate enlargement. Symptoms most improved in men exhibiting significant BPH symptoms, often after several weeks of consistent use, resulting in enhanced overall quality of life with sustained symptom relief.
How it works
Saw palmetto primarily exerts its therapeutic effects by inhibiting the enzyme 5α-reductase, responsible for converting testosterone into dihydrotestosterone (DHT). By reducing DHT levels, saw palmetto alleviates prostate enlargement and associated symptoms. Furthermore, it appears to disrupt androgen-receptor binding and exhibits anti-estrogenic properties, further enhancing urinary function and alleviating discomfort in the urinary and reproductive systems.
Side effects
Saw palmetto is generally well tolerated, with mild side effects noted, such as digestive discomfort and headaches, reported in over 5% of users. Serious adverse effects are rare, and it is considered safer compared to traditional medications like finasteride, which may cause more severe sexual side effects. While documented drug interactions are infrequent, caution is advised for individuals who are pregnant or breastfeeding due to a lack of comprehensive safety data. Patients with specific health conditions should also consult with healthcare professionals before use, although the overall safety profile is established for adult males using saw palmetto medicinally.
Dosage
The typical recommended dosage for saw palmetto is between 160 mg taken twice daily or a single dose of 320 mg daily, ensuring that the formulation comprises 80-90% of active components. Research supports that doses up to 320 mg are effective for symptom relief, while an upper limit of 960 mg daily is considered safe. Higher dosages do not necessarily result in improved effectiveness and should generally be avoided. Consistent dosing timing is advisable, although the exact timing of intake does not significantly influence effectiveness. The extraction method can affect the supplement's potency, with hexane extracts being preferred for their higher concentration of active ingredients.
