The 500/1000 Da (Daltons) difference reflects average molecular weight of the peptides. Lower molecular weight (500 Da) = higher bioavailability and faster absorption; 1000 Da = standard hydrolyzed peptides.
Oysters are naturally rich in zinc. Hydrolyzed oyster extract typically contains 0.5-2% zinc naturally. Zinc-enriched specifications are available with higher zinc content.
Oyster Extract Peptides are commonly combined with Zinc Picolinate, Maca, and Tribulus in men's vitality formulations. We recommend consulting with your formulation team.
Oyster Extract is permitted as a food supplement ingredient in the EU. Allergen declaration (shellfish) is required on label. Specific regulatory status depends on intended application and labeling.
Total Protein is quantified via Kjeldahl (N × 6.25) or Dumas combustion method.
Standard MOQ is 25 kg. Smaller quantities (5-10 kg) are available for evaluation.
Yes. Custom specifications (e.g., specific molecular weight, zinc content, particle size) can be discussed with our coordination team.
Standard documentation includes COA, MSDS, allergen statement, Non-GMO statement. Additional documentation available upon request from production partners.
