Products Description
Melatonin (MT) is a natural hormone secreted by the pineal gland, chemically known as N-acetyl-5-methoxytryptamine. This 20 mg formulation provides enhanced potency for significant sleep regulation through MT1 and MT2 receptors. The pure powder form allows flexible application in various supplement formulations while maintaining maximum bioavailability.
Our Pure Melatonin 20 mg offers a high-potency sleep support solution derived from premium-grade raw materials. Sourced from fermentation and processed without hazardous chemicals, this product ensures purity and environmental sustainability. Ideal for dietary supplement manufacturers and health-conscious consumers seeking reliable sleep aid formulations.
Professional Grade: USP & Pharma Grade Compliance
High-purity crystalline melatonin that regularly satisfies and surpasses USP (U.S. Pharmacopeia) and EP (European Pharmacopoeia) requirements is offered by TIANJIN YINAO, a well-known manufacturer of melatonin powder bulk. Our substance has been specially improved for international manufacturers who want strict batch-to-batch uniformity and zero contaminants.
Purity: ≥≥ 99.5% (HPLC Verified)
Compliance Standards: USP43 / EP10 Grade
Manufacturing: Produced in a GMP-certified facility with full traceability.
Advanced Application: Sustained-Release (SR) Formulations

Current pharmaceutical and nutraceutical companies are switching from immediate-release to Extended-Release (XR) or Sustained-Release (SR) technologies. Melatonin powder from TIANJIN YINAO is specially tailored for these cutting-edge delivery methods:
- Particle Size Optimization: To guarantee consistent integration with matrix-forming polymers (such HPMC) and a regulated release profile, it is available in particular mesh sizes (e.g., 80–100 mesh).
- Formulation Integrity: Our substance mimics the body's natural circadian melatonin secretion by maintaining its molecular stability during high-pressure tableting and aqueous coating procedures.
- B2B Value Proposition: Create high-margin "All-Night Support" products with improved customer efficacy over conventional immediate-release supplements by utilizing our premium raw material.
Function
- Sleep Regulation: By simulating the natural rise in hormones at night, it shortens the time it takes to fall asleep (Sleep Onset Latency) and enhances the quality of sleep.
- Jet Lag Recovery: For shift workers and regular travelers, it efficiently resynchronizes the internal clock.
- Strong Antioxidant: Promotes antioxidant enzymes (GPx, SOD) and directly scavenges free radicals. It can pass through the blood-brain barrier since it is soluble in both fat and water.
- Immunological modulation: Promotes the generation of T-helper cells and other cytokines, which strengthens the immunological response.
- Neuroprotection: By lowering oxidative stress in brain tissues, research points to possible advantages in delaying cognitive decline.
Applications
- The most popular use is in dietary supplements (capsules, tablets, gummies, liposomal sprays). The usual dosages are between 1 and 10 mg (or, depending on your list, 20 mg for high-strength).
- "Relaxation" drinks or functional nibbles intended for consumption at night are examples of functional foods and beverages.
- Pharmaceuticals: Used in prolonged-release insomnia formulations that require a prescription.
- Cosmetics: Because of its antioxidant and DNA-repairing qualities, it is used in "night repair" lotions and serums.
