Why this scored 44/100
"Sleep Formula" as a product name universally signals a melatonin + magnesium + L-theanine + valerian + chamomile proprietary stack with no per-active dose disclosure. Every one of those ingredients has legitimate sleep evidence at specific doses (melatonin 0.3-5mg for sleep onset per Ferracioli-Oda 2013; magnesium glycinate 200-400mg per Abbasi 2012; L-theanine 200mg per Kim 2019; valerian 300-600mg per Bent 2006), but a bundled "formula" that hides per-active mg cannot be evaluated against any of those doses. The specific concern with sleep blends is that melatonin is systematically overdosed in the DTC market (10mg is common; the studied physiological dose is 0.3-1mg), leading to grogginess, nightmares, and morning-hormone disruption without any efficacy gain. Auto-failed under proprietary_blend_hides_dose.
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.
