Description

Branched Chain Amino Acids CAS NO 308062-69-3 are a critical group of essential amino acids, comprising L-Leucine, L-Isoleucine, and L-Valine, which play a fundamental role in protein synthesis and metabolic regulation. Their primary commercial value lies in their ability to support muscle protein synthesis, reduce fatigue, and enhance recovery, making them indispensable for nutritional and therapeutic formulations. This high-purity blend is essential for manufacturers in the sports nutrition, clinical nutrition, pharmaceutical, and functional food and beverage industries seeking reliable, quality-assured ingredients.

Application

• Sports & Performance Nutrition: Core ingredient in pre-workout, intra-workout, and post-workout supplements, protein powders, and ready-to-drink beverages to promote muscle growth, reduce exercise-induced fatigue, and accelerate recovery.
• Clinical & Medical Nutrition: Used in enteral and parenteral nutrition formulas, and therapeutic supplements for patients with muscle-wasting conditions, liver disease (e.g., hepatic encephalopathy), trauma, or surgical recovery to support nitrogen balance and tissue repair.
• Pharmaceutical Intermediates: Serves as a key building block in the synthesis of more complex peptides, active pharmaceutical ingredients (APIs), and infusion solutions.
• Functional Food & Beverages: Incorporated into fortified foods, health drinks, and meal replacements to enhance the protein quality and provide specific metabolic health benefits.
• Animal Feed & Pet Nutrition: Added to premium livestock feed, aquaculture diets, and companion animal food to optimize growth performance, feed efficiency, and overall animal health.
• Cosmetic & Personal Care: Utilized in skin care and hair care formulations for their moisturizing properties and role in supporting skin barrier function and collagen synthesis.

Quality Control

Our Branched Chain Amino Acids are manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and composition. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (HPLC), enantiomeric purity, heavy metals, residual solvents, and microbiological limits. Our production can adhere to relevant standards such as USP, FCC, and Ph. Eur. for nutritional and pharmaceutical applications, ensuring reliable quality and supply chain transparency for our global B2B partners.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation. Keep away from incompatible materials.
