Black maca (Lepidium meyenii, black phenotype) has small trials for libido and sperm parameters (Gonzales et al. 2001-2013). Studied doses range 1.5-3g/day of gelatinized maca root — this 750mg of a 50:1 extract translates to a claimed 37,500mg raw-root equivalent, which follows industry convention but overstates real-world potency since 50:1 concentration ratios rarely retain the full active-compound spectrum of raw maca. Marketing the raw-equivalent number as the headline is borderline misleading naming. Would move to Standard 65+ with gelatinized (heat-processed) claim and macamide/macaene standardization; sustained-ingredient trials favor 3g gelatinized whole root over concentrates.
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.

Marketing the raw-equivalent number as the headline is borderline misleading naming. Would move to Standard 65+ with gelatinized (heat-processed) claim and macamide/macaene standardization; sustained-ingredient trials favor 3g gelatinized whole root over concentrates.
Strongest: Safety at 65/100 (adverse-event profile, interaction risk, and dose ceiling) and Formulation at 60/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Transparency at 55/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 55/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
