Why this scored 62/100
Fruiting-body-only Hericium erinaceus extract in a 2 oz liquid tincture. The fruiting-body-only qualifier is genuinely important — much of the negative press around lion's mane 'not working' comes from myceliated grain products that are largely starch with trace mushroom, whereas fruiting-body extracts contain the hericenones and erinacines that drive the NGF-related neuroplasticity mechanism. Human evidence is small but consistent: Mori 2009 (Japanese adults 50-80, mild cognitive impairment, 3 g/day for 16 weeks) and Saitsu 2019 both show cognitive improvement vs placebo. Effect sizes are modest and only durable while dosing continues. The product does not disclose extract strength (e.g. beta-glucan percentage, hericenone content, extract ratio) or milligrams-per-serving, which caps the Verified potential. Fruiting-body sourcing and honest cognitive positioning earn mid-Standard credit — this is one of the better lion's mane products a small brand could ship, provided the ingredient claim is accurate.
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.

Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
