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 in How we scored this, above. 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.

Frequently asked questions

Auto-generated from Vyvata's scoring data for this product. For general questions about the store (shipping, returns, wholesale), see the site FAQ.

What is THE BLACK STACK?

THE BLACK STACK is a product from BRAINSUPREME, categorized under Cognitive health & nootropics in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.

How does THE BLACK STACK score on the Vyvata rubric?

30/100 overall — Rejected tier (0–49 band). Per-dimension breakdown: Safety 40, Sustainability 40, Manufacturing 35, Evidence 30, Formulation 25, Transparency 15. Scored as of 2026-08-24.

Why did THE BLACK STACK score in the Rejected tier?

Explicitly described as '2.5x the proprietary BRAINSUPREME blend' with no ingredient list or doses in the description. Nootropic stacks require dose-transparent actives (L-theanine, caffeine, alpha-GPC) to substantiate cognitive claims (Camfield 2014).

What are the strongest and weakest aspects of this product?

Strongest: Safety at 40/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 40/100 (sourcing practices, packaging, and corporate practice). Weakest: Formulation at 25/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Transparency at 15/100 (dose disclosure vs proprietary blends, and honesty of marketing claims). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.

Is THE BLACK STACK third-party tested?

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.

Why was this product auto-rejected?

This product triggered the Vyvata auto-fail rule "proprietary_blend_hides_dose", which places it in the Rejected tier regardless of its scores on other dimensions. See the full explanation above and the methodology page for the current list of auto-fail rules.

Are there higher-scoring alternatives to THE BLACK STACK?

The top-ranked cognitive health & nootropics product in the Vyvata catalog is currently Nordic Naturals Ultimate Omega 2X – High-Potency Fish Oil | 2150 mg EPA & DHA | Lemon Flavor, 120 Softgels at 87/100. See the full ranked list of 212 scored products in this subcategory at https://vyvata.com/pages/best-cognitive-health-and-nootropics-supplements-ranked.

What does the Vyvata score mean?

The Vyvata Scoring Framework rates every listed product 0–100 across six dimensions: Evidence, Formulation, Manufacturing, Safety, Transparency, and Sustainability. Tier bands: Elite 85–100 (top-tier evidence + formulation + manufacturing), Verified 70–84 (strong on most dimensions), Standard 50–69 (solid but with weaknesses called out), Rejected 0–49 (specific failures documented). Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
