Description

Calcium Di-L-Tryptophanate is a high-purity, organically complexed calcium salt of the essential amino acid L-Tryptophan. This compound is valued for its enhanced bioavailability and stability, offering a superior source of both calcium and tryptophan in a single molecule. It is primarily utilized in the pharmaceutical and nutraceutical industries for the formulation of dietary supplements, clinical nutrition products, and functional foods aimed at supporting bone health and neurological function.

Application

• Dietary Supplements: As a dual-action ingredient providing bioavailable calcium for bone support and L-Tryptophan as a precursor for serotonin and melatonin synthesis.
• Clinical Nutrition: For use in medical food formulations and enteral/parenteral nutrition where targeted nutrient delivery is critical.
• Functional Food & Beverage Fortification: To enrich products like dairy alternatives, meal replacements, and health drinks with essential minerals and amino acids.
• Pharmaceutical Intermediates: Serves as a key starting material or active pharmaceutical ingredient (API) in the synthesis of more complex therapeutic agents.
• Animal Nutrition (Feed Grade): Incorporated into premium livestock and poultry feed to improve growth performance, feed efficiency, and overall animal well-being.
• Cosmetic & Personal Care: Used in skincare formulations for its potential role in promoting skin health and barrier function.

Quality Control

Our Calcium Di-L-Tryptophanate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment. We can support compliance with relevant standards such as USP, FCC, and in-house pharmaceutical-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a low-humidity environment to prevent caking and degradation. Keep away from incompatible materials.
