Digestive enzymes

Buyers should prioritize multi-enzyme complexes that include Protease (for proteins), Amylase (for carbohydrates), and Lipase (for fats). For specialized markets, ensure the inclusion of Lactase for lactose intolerance, Alpha-galactosidase for gas reduction from legumes, and Cellulase for fiber breakdown. Always verify the enzyme activity units (e.g., HUT, DU, FIP) rather than just weight in milligrams, as activity levels determine product efficacy.

As health supplements, these products must be manufactured in GMP-certified (Good Manufacturing Practice) facilities. For the US market, ensure FDA registration and compliance with DSHEA guidelines. For the EU, products must meet EFSA regulations. Additionally, obtaining ISO 22000 or HACCP certifications is essential for food safety management, while Halal or Kosher certifications can significantly expand market reach in specific regions.

Enzymes are proteins that can denature easily. Buyers should inquire about micro-encapsulation technology or enteric coating, which protects enzymes from stomach acid and ensures they reach the small intestine. Furthermore, check if the supplier uses stability testing to guarantee potency until the expiration date, and confirm if the product requires cold-chain logistics or if it is shelf-stable at room temperature.

Most professional suppliers on Made-in-China.com offer extensive OEM services, including custom formulation (adjusting enzyme ratios), dosage form selection (capsules, tablets, powders, or chewables), and packaging design. Buyers can also request clean label options, such as non-GMO, gluten-free, and the absence of artificial fillers or magnesium stearate to appeal to health-conscious consumers.

To prevent degradation, specify temperature-controlled shipping or use moisture-proof, vacuum-sealed bulk packaging. It is highly recommended to conduct a third-party lab test (e.g., SGS or Intertek) upon arrival to verify that the enzyme activity levels match the Certificate of Analysis (COA) provided by the supplier.

Focus on tiered pricing based on activity units rather than volume alone. Request a sample batch for pilot testing before committing to a large order. Negotiate for transparency in the raw material supply chain, ensuring the enzymes are sourced from reputable microbial or plant-based origins (like Aspergillus oryzae or Papaya).

Utilize the Secured Trading services provided by Made-in-China.com to protect your payments. Conduct a virtual or on-site factory audit to inspect the laboratory equipment and clean-room standards. Always verify the supplier's Export License and their history of compliance with international health authorities to avoid customs seizures.

Enzymes are often classified under HS Code 3507. Be aware of specific import duties and VAT in your target country. Ensure all labeling complies with local laws, including accurate ingredient lists, allergen warnings, and health claims, as incorrect labeling is the leading cause of customs delays and rejections.
