Saw Palmetto Berry Complex Proprietary Blend
Also known as: Serenoa repens, Sabal serrulata, Saw Palmetto, Saw Palmetto Berry
Overview
Saw palmetto, derived from the berries of the *Serenoa repens* plant native to the southeastern United States, has a long history of use in traditional medicine, primarily for treating benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). The extract contains fatty acids, sterols, and other compounds, but the lack of standardization across different formulations can lead to variability in their effects. Research on saw palmetto is extensive, including numerous systematic reviews and meta-analyses, but the results are mixed, likely due to differences in formulations and study methodologies. While some studies suggest mild to moderate improvements in urinary symptoms and flow, others show no significant benefits. It is important to note that saw palmetto is a phytotherapeutic agent and dietary supplement, not a pharmaceutical drug, and its effects may vary among individuals.
Benefits
Some studies suggest that saw palmetto may provide mild to moderate improvement in urinary symptoms and flow for men with BPH/LUTS, without necessarily reducing prostate size. A meta-analysis indicated that symptom improvement might be comparable to that achieved with tamsulosin, a common medication for BPH. Potential secondary benefits include a decrease in nocturia (nighttime urination). However, the effect sizes and clinical significance can vary, and some studies have not shown significant benefits. The time course for observing benefits is not well-documented, but improvements may be noticeable within several months of consistent use. The quality of available evidence is variable, with some studies using more standardized extracts and rigorous methodologies than others.
How it works
The mechanism of action of saw palmetto is not fully understood, but it is believed to involve the inhibition of 5-alpha-reductase, an enzyme that converts testosterone to dihydrotestosterone (DHT). By inhibiting this enzyme, saw palmetto may reduce DHT levels in the prostate, potentially alleviating BPH symptoms. However, this effect is not consistently supported by evidence. Saw palmetto may also interact with hormonal pathways, particularly those involving testosterone and DHT, and may target androgen receptors and enzymes involved in testosterone metabolism. The absorption and bioavailability of saw palmetto can vary depending on the formulation.
Side effects
Saw palmetto is generally considered safe, with few reported side effects. The most common side effects are gastrointestinal issues, such as nausea and diarrhea. Less common side effects include headache and dizziness. Rare side effects may include allergic reactions. There is potential for interactions with blood thinners and medications affecting blood pressure, so caution is advised in patients with bleeding disorders or those taking anticoagulants. Saw palmetto is contraindicated in pregnancy and breastfeeding due to a lack of safety data. It is important to monitor for any adverse effects and to consult with a healthcare professional before using saw palmetto, especially if you have underlying medical conditions or are taking other medications.
Dosage
The typical recommended dosage of saw palmetto is between 160-320 mg per day. It is often recommended to take saw palmetto with meals to reduce the risk of gastrointestinal side effects. Some studies suggest that hexane extracts may be more effective than other forms. Bioavailability may be influenced by the formulation and the presence of fatty acids. While a maximum safe dose is not well-defined, higher doses have been used in studies without significant adverse effects. It's important to note that individual responses to saw palmetto can vary, and it's advisable to start with a lower dose and gradually increase as needed, while monitoring for any side effects.
