Description

Zinc Methionine Sulfate is a stable, bioavailable organic complex of the essential trace mineral zinc and the amino acid methionine. This compound is specifically designed to enhance zinc absorption and utilization in biological systems, offering superior bioavailability compared to inorganic zinc salts. It serves as a critical nutritional ingredient for animal feed, aquaculture, and human dietary supplements, supporting immune function, growth, and metabolic processes. Zinc Methionine Sulfate CAS NO 56329-42-1 is a high-purity material manufactured under strict quality control for consistent performance.

Application

• Animal Feed Additive: A premier source of bioavailable zinc for poultry, swine, and ruminants to promote growth, hoof health, and immune system function.
• Aquaculture Nutrition: Incorporated into fish and shrimp feed to prevent zinc deficiency, support skeletal development, and improve overall health and survival rates.
• Pet Food & Companion Animal Supplements: Used in premium dog and cat food formulations for skin, coat, and joint health support.
• Human Nutritional Supplements: Serves as a high-quality zinc source in capsule, tablet, and powder formulations for dietary supplements.
• Fertilizers & Crop Nutrition: Applied in specialty fertilizers as a micronutrient to correct zinc deficiencies in soil and improve plant growth and yield.
• Pharmaceutical Intermediates: Utilized in the synthesis of specialized pharmaceutical compounds requiring a bioavailable zinc source.
