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 →
Methylcobalamin is the preferred bioactive B12 form for methylation-cycle support and neurological uptake (Zhang 2013), superior to cyanocobalamin in MTHFR carriers and in neurological deficiency. Sublingual delivery bypasses intrinsic-factor absorption issues (relevant in older adults and PPI users). Held below Elite by absence of a named-source methylcobalamin, no third-party certification, and typical mass-market flavoring/sweetener composition. Would move to Verified 75+ with clear mcg dose and independent COA.
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.

Held below Elite by absence of a named-source methylcobalamin, no third-party certification, and typical mass-market flavoring/sweetener composition. Would move to Verified 75+ with clear mcg dose and independent COA.
Strongest: Formulation at 76/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Evidence at 74/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Manufacturing at 65/100 (third-party testing, GMP compliance, and facility audit status) 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.
Would move to Verified 75+ with clear mcg dose and independent COA.
