Six-dimension breakdown
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 in How we scored this, above. 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.
Frequently asked questions
Auto-generated from Vyvata's scoring data for this product. For general questions about the store (shipping, returns, wholesale), see the site FAQ.
Does this product actually raise testosterone?
The evidence is weak. Chrysin has poor oral bioavailability and limited human data supporting a testosterone-raising effect, and nettle root's lignan mechanism, while biologically plausible, lacks strong clinical trial support.
What is muira puama used for?
It's a traditional Amazonian botanical historically used for libido and energy, with limited modern clinical research behind it.
Is this a trustworthy manufacturer?
Yes — Life Extension has an established cGMP manufacturing history and consistently discloses full ingredient amounts, which is why manufacturing and transparency score well here even though the underlying efficacy claim is weak.
Are there safety concerns with this formula?
Zinc is included alongside several botanicals; total zinc intake should be considered if combined with other zinc-containing supplements, but no major safety concerns are known at labeled doses.
