Glutathione supplement manufacturers

Buyers must prioritize the purity level (ideally ≥98%) and the molecular form of the ingredient. Reduced Glutathione (GSH) is the standard active form, but Liposomal Glutathione or S-Acetyl Glutathione are increasingly popular due to their superior bioavailability and absorption rates. Ensure the CAS number (70-18-8) is verified in the technical data sheet.

For B2B cross-border trade, the supplier's facility must hold GMP (Good Manufacturing Practice) and ISO 22000 or HACCP certifications. If exporting to the US, FDA facility registration is required; for the EU, compliance with EFSA regulations and Novel Food status should be confirmed. Always request a Certificate of Analysis (COA) for every batch to verify heavy metal limits (Lead, Arsenic, Mercury) and microbial safety.

Glutathione is sensitive to oxidation, light, and temperature. You should request stability testing reports (accelerated and real-time) from the manufacturer. Professional suppliers will use opaque, airtight packaging (such as amber glass or induction-sealed HDPE bottles) and may include desiccants to maintain a shelf life of typically 24 months.

Most professional manufacturers on Made-in-China.com offer private labeling. This includes choosing the delivery format—capsules, tablets, softgels, or liposomal liquids—as well as custom dosage (e.g., 250mg, 500mg). You can also request synergistic formulations, such as adding Vitamin C or Alpha Lipoic Acid, which help regenerate Glutathione in the body.

The biggest risks are customs seizure due to non-compliant labeling and ingredient discrepancies. Ensure all labels meet the destination country's language and regulatory requirements (e.g., Supplement Facts panel). Use third-party inspection services (like SGS or Intertek) to conduct random sampling before the final balance payment is made.

Raw material prices for Glutathione can fluctuate based on the cost of precursor amino acids. It is wise to negotiate tiered pricing based on volume. For startups, look for suppliers on Made-in-China.com that offer low MOQs (e.g., 500–1,000 bottles) for standard formulas, while reserving deep discounts (15-25%) for bulk raw powder orders exceeding 100kg.

Always utilize Trade Assurance or secure payment terms to protect your capital. Regarding logistics, supplements are sensitive to heat; for large sea freight shipments, consider reefer containers (temperature-controlled) if crossing tropical zones. For air freight, ensure the supplier provides MSDS (Material Safety Data Sheet) to prevent delays during airline security screening.
