Why this scored 60/100
Combination of L-theanine + melatonin is a common OTC sleep template. L-theanine at 100-200mg has evidence for sleep-onset and subjective sleep quality (Rao 2015), and melatonin at physiological doses (0.3-1mg) improves sleep latency (Auld 2017 meta). Swanson sleep formulas historically use 3-5mg melatonin - well above the physiological range needed - without disclosing that lower doses match endogenous secretion better. No morning-grogginess or teen-use warnings visible. Would move to Verified 70+ with a physiological 0.5-1mg melatonin dose and explicit chronotype/duration guidance.

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.

Why did Sleep Formula with L-Theanine and Melatonin score in the Standard tier?
Combination of L-theanine + melatonin is a common OTC sleep template.

What are the strongest and weakest aspects of this product?
Strongest: Evidence at 62/100 (quality of published RCT support for the active ingredients at the label dose) and Transparency at 62/100 (dose disclosure vs proprietary blends, and honesty of marketing claims). Weakest: Safety at 58/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 50/100 (sourcing practices, packaging, and corporate practice).
