What is Saw Palmetto Extract 20:1 Used For? What is its Purpose?
What is Saw Palmetto Extract 20:1 used for? Dwarf Palm (Serenoa repens) is a standardized herbal raw material used in dietary supplements for traditional support of prostate (BPH) and lower urinary tract symptoms, due to its liposterolic extract rich in fatty acids and phytosterols (especially beta-sitosterol).

Benefits and Main Uses of Saw Palmetto Extract 20:1
- Prostate and urinary tract symptoms: Commonly used as a traditional herbal support for lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH); it is one of the most studied herbal agents.
- Evidence status: The latest Cochrane review concluded that dwarf palm did not significantly improve urological symptoms or quality of life compared to placebo; evidence is conflicting (limited/conflicting evidence).
- Good tolerability: According to the Cochrane review, the safety profile is generally positive; side effects are mostly mild.
- Hormonal balance (mechanistic): Experimental studies suggest that the extract inhibits the 5-alpha-reductase enzyme, which converts testosterone to DHT (mechanistic data).
