B-Performance 8

Six-dimension breakdown

Why this scored 48/100

Vitamin Patch Club 'Super8' B-Performance is a transdermal vitamin patch delivering all 8 essential B vitamins for cardiovascular support, metabolic burn, and energy. The core mechanism problem is that transdermal vitamin absorption has essentially no peer-reviewed bioavailability evidence for most water-soluble vitamins, including B-complex. The skin is designed to be a barrier — it evolved to keep foreign molecules out. Compounds that can cross skin efficiently are small (under ~500 Da), lipid-soluble, and often require permeation enhancers (like the skin-penetration drivers in transdermal nicotine or hormone patches). B vitamins are mostly water-soluble (except B12), typically well over 500 Da, and have essentially no clinical evidence of meaningful transdermal absorption despite marketing claims across the vitamin-patch industry. B12 is the one exception with limited pharmacokinetic support (Berlin 1968 injectable-vs-oral B12 studies; a 2019 open-label transdermal B12 patch study by Vitamin Patch Club vendors showed variable serum-level increases). Autofail on unverified_medical_claim for the 'cardio support, metabolic burn, energy' claims delivered by an unvalidated route. Not a category Vyvata endorses as-is.

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 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.
