Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
L-carnitine + Lepidium (maca) is a Turkish-market male-vitality style formula. L-carnitine has moderate RCT data for sperm parameters (Lenzi 2003, Balercia 2005) and modest fat-oxidation support; maca has small trials for libido (Gonzales 2002). Per-cap mg not disclosed from title, only 30 capsules per pack suggests short duration. Beauty Care Bag reseller channel with no US COA. Would move to Verified 70+ with per-active mg at studied levels and US-market third-party testing.
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.

Strongest: Evidence at 60/100 (quality of published RCT support for the active ingredients at the label dose) and Safety at 60/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Transparency at 52/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Manufacturing at 48/100 (third-party testing, GMP compliance, and facility audit status). 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.
Would move to Verified 70+ with per-active mg at studied levels and US-market third-party testing.
