Why this scored 50/100
Saw palmetto (Serenoa repens) is one of the most-studied herbal supplements for benign prostatic hyperplasia (BPH), with a moderate evidence base. Early trials suggested benefit (Wilt 1998 meta-analysis) but larger and more rigorous trials showed less benefit (Barry 2011 CAMUS trial, JAMA, found saw palmetto 320-960mg/day equivalent to placebo for lower urinary tract symptoms). The current consensus is that saw palmetto has small effects on LUTS at 320mg/day of the standardized lipidosterolic extract, comparable to lifestyle modification but inferior to alpha-blockers or 5-alpha-reductase inhibitors for moderate-to-severe BPH. Drops format for saw palmetto is unusual — the evidence is primarily on the lipidosterolic extract (Permixon, Serenoa berry extract) delivered in capsules at 320mg/day. Vivalo does not disclose extraction ratio, standardization, or per-drop dose. Standard 50/100: real ingredient with moderate evidence for a narrow use case, held down by format uncertainty and no dose disclosure. Adding 'vitamin' to the name is misleading — no vitamins are disclosed.

Evidence & sources
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
