Saw Blend
Also known as: Saw palmetto, Sabal, American dwarf palm tree, Serenoa repens
Overview
Saw palmetto (*Serenoa repens*) is a small palm native to the southeastern United States. Its berries are used to produce extracts known for their medicinal applications, especially in urology. This herbal supplement is primarily recognized for alleviating symptoms associated with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). The extract contains bioactive compounds such as phytosterols and fatty acids, which are thought to contribute to its therapeutic properties. While the body of research on saw palmetto is substantial, the quality and outcomes of studies can vary greatly, making it essential to consider extract quality and formulation when evaluating its effectiveness.
Benefits
Saw palmetto extract (SPE) has demonstrated several evidence-based benefits, particularly in improving peak urinary flow and alleviating symptoms of BPH. In clinical trials, it has shown comparable effects to tamsulosin, a prescription medication used for the same condition. Some studies indicate that SPE may offer anti-proliferative and pro-apoptotic benefits, further supporting its use for prostate health. Specifically, men suffering from BPH or LUTS may experience significant improvements in quality of life with regular supplementation. Evidence suggests that the onset of benefits often appears within weeks of continuous use, although the extent of improvement can vary.
How it works
The primary mechanism of action for saw palmetto is its inhibition of the enzyme 5-alpha-reductase, which leads to decreased levels of dihydrotestosterone (DHT), a hormone implicated in prostate enlargement. Additionally, SPE exhibits anti-inflammatory and anti-androgenic properties that may further alleviate symptoms related to prostate health. These actions primarily influence the endocrine system, particularly affecting androgen metabolism, and enhance urinary function.
Side effects
Saw palmetto is generally recognized as safe, with a favorable safety profile. The most common side effects, occurring in over 5% of users, include gastrointestinal disturbances such as nausea and stomach discomfort. Less frequently, between 1-5%, individuals may experience sexual dysfunction or allergic reactions. Serious adverse effects are rare, appearing in less than 1% of users. While drug interactions are minimal, caution is advised, especially in individuals with bleeding disorders due to potential antiplatelet effects. Pregnant and breastfeeding individuals should avoid usage due to a lack of safety data.
Dosage
The recommended dosage of saw palmetto typically ranges from 160 mg to 320 mg per day, with most studies advocating for an optimal daily intake of 320 mg to achieve effective results. Some research indicates that doses up to 960 mg can be safely used without significant adverse effects. For best outcomes, consistent daily dosing is recommended, either once or twice daily. Select formulations, especially liquid extracts with high concentrations of beneficial compounds, may provide better absorption. Factors influencing bioavailability include the method of extraction employed.
