Solgar Melatonin 3mg 120 Nuggets

Six-dimension breakdown

Why this scored 66/100

Solgar is a decades-established US supplement brand under Nestlé Health Science with a demonstrated commitment to standardized single-ingredient formulations, disclosed doses, and controlled manufacturing (GMP-certified US facilities, kosher-parve certification, published allergen statements). The 3 mg melatonin dose is a legitimate mid-range dose — 0.3-1 mg is sufficient for chronobiotic effects and 3-5 mg is the more common consumer sleep-latency dose, both bracketed by published RCT evidence. Melatonin itself has robust meta-analytic support for reducing sleep-onset latency and modest support for jet-lag mitigation. Where Solgar loses transparency points: no independent third-party COA is routinely published per lot, and consumer-grade melatonin as a category has repeatedly been shown (Erland/Saxena 2017 JAMA) to have wide label-vs-actual dose variance across brands. Solgar sits in the better-audited quartile of that space but does not publish per-lot assay data publicly. Solid Standard-tier product for occasional sleep-onset difficulty; not a candidate for chronic use without a clinician conversation.

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.
