Frequently Asked Questions
Saw palmetto (Serenoa repens) is a small palm tree native to the southeastern United States. The extract from its berries contains various fatty acids and plant sterols that may inhibit 5-alpha-reductase, an enzyme that converts testosterone to dihydrotestosterone (DHT). By reducing DHT levels, saw palmetto may help prevent the enlargement of the prostate gland and alleviate urinary symptoms associated with benign prostatic hyperplasia (BPH).
Most clinical studies have used a dosage of 320 mg per day of saw palmetto extract, standardized to contain 85-95% fatty acids and sterols. This is typically divided into two doses of 160 mg each. It's important to use a high-quality extract rather than whole berries or non-standardized preparations, as the concentration of active compounds can vary significantly.
Saw palmetto is not a quick-fix solution. Most studies show that it takes about 4-6 weeks of consistent use before noticeable improvements in urinary symptoms occur. Some men may need to take it for up to 3 months before experiencing the full benefits. It's important to be patient and consistent with the supplementation.
Saw palmetto is generally well-tolerated by most men. Mild side effects may include digestive complaints (such as nausea or diarrhea), headache, dizziness, or fatigue. Regarding drug interactions, saw palmetto may interact with hormone therapies, blood thinners like warfarin, and certain medications metabolized by the liver. It's essential to consult with a healthcare provider before taking saw palmetto, especially if you're on medication or have existing health conditions.
