Melatonin Pure Bulk Powder | High Dose (20g–500g)

Pure pharmaceutical-grade melatonin in bulk powder form — no capsule, no fixed dose, no added ingredients. Manufactured at our cGMP facility in Santa Rosa, California. Every batch tested for identity and potency before release. Available in 20g, 40g, 100g, 250g, and 500g.

What’s In It

• Melatonin: Pharmaceutical-grade, 99%+ purity
• Nothing else — pure melatonin powder, no fillers, no flow agents, no binders
• Available sizes: 20g | 40g | 100g | 250g | 500g (resealable bags)

Scale Requirement

A milligram-accurate scale is required. Melatonin is active at milligram quantities — amounts that weigh between 0.005g and 0.120g. A kitchen scale cannot detect these amounts. You need a precision scale accurate to 0.001g (1mg). Scoops are included for handling only — never use a scoop for measurement.

What “Pure” Actually Means

The 2017 Erland and Saxena study (Journal of Clinical Sleep Medicine) found that over 70% of melatonin supplements deviated substantially from their label claims — ranging from 83% below to 478% above stated dose. Pharmaceutical-grade melatonin powder is specified at 99%+ purity, verified by HPLC. Every batch we release has a lot-specific Certificate of Analysis available on request.

The Research Behind High-Dose Melatonin

Bulk melatonin powder allows users to access the dose ranges studied in peer-reviewed research — doses substantially above standard OTC products. Melatonin has been studied for antioxidant properties, cytoprotective effects, oncology support applications, neurological research, and aging biology — all at doses that require either bulk powder or high-dose capsules.*

Storage

Store in a cool, dry location away from direct light. Keep sealed when not in use. Melatonin degrades with light, heat, and moisture exposure — proper storage preserves potency over time.
