Product Identity
Ingredient: Melatonin
Assay: 50%
Form: Liposomal powder
Carrier: Sunflower Lecithin + Phytosterols
Batch Standard: Complies with full in-house quality specifications2. Absorption BreakthroughConventional melatonin has low gastrointestinal stability, fast metabolism, and poor absorption efficiency, leading to low bioavailability and inconsistent effects.
Our liposomal delivery system mimics natural cell structure, encapsulates melatonin to protect it from stomach acid and digestive enzymes, improves solubility and permeability, and boosts bioavailability by 2–5 times for more stable and efficient effects.
3. Carrier & TechnologyThree Carrier SystemsSunflower Lecithin (clean label, non‑GMO, soy‑free)
Sunflower Lecithin + Phytosterols (enhanced stability, better dispersion)
Sunflower Lecithin + Cholesterol (high structural rigidity, long‑lasting protection)

8. FAQWhat is Liposomal Melatonin 50%?It is 50% melatonin encapsulated in liposomes made from sunflower lecithin and phytosterols to improve absorption and stability.
How does liposomal technology improve melatonin absorption?Liposomes protect melatonin from stomach acid, enhance solubility, and support direct cellular uptake, raising bioavailability 2–5 times.
What is the difference between liposomal and regular melatonin?Liposomal has much higher bioavailability, better stability, and more consistent performance than plain powder or liquid.
How to choose carrier and process?Choose sunflower lecithin + phytosterols for stability; spray drying for mass production; freeze drying for premium stability.
What about solubility, particle size, and stability?Good water dispersibility; uniform particle size; stable for 24 months when stored at 2–8°C in sealed conditions.
What certificates and export documents are provided?COA, HPLC, TEM, COO, Health Certificate and full export support.
What can you customize?Assay, carrier, process, particle size, product form, packaging, and co‑delivery systems.
What finished products can use this ingredient? What is shelf life and storage?Suitable for drinks, capsules, tablets, gummies; shelf life 24 months; store cool, dry, 2–8°C.
