L-Aspartic Acid is the naturally active L-isomer of aspartic acid. It is a non-essential amino acid (the human body can synthesize it, while supplemental intake can further enhance metabolic functions). It is widely found in natural foods such as legumes, meat, and vegetables. Industrial production relies mainly on microbial fermentation , a mature process that delivers high purity. The product appears as a white crystalline powder with a mildly sour taste and excellent water solubility.
Core Applications
Food Industry
Nutritional enhancer
Used in infant formula and elderly nutrition powders to supplement essential amino acids, promote protein synthesis, and support intestinal absorption.
Flavor improvement & preservation
Added to fruit juices and sports drinks to adjust acidity, enhance fruity aroma complexity, and mask the bitterness of artificial sweeteners. In prepared foods (such as frozen vegetables and processed poultry), it helps delay oxidation and spoilage.
Health foods
Used in liver-support nutritional capsules, commonly combined with L-ornithine (1:1 ratio) to help improve liver function.
Pharmaceutical & Personal Care
Pharmaceutical raw material:
Used in the production of compound amino acid injection solutions for postoperative recovery and parenteral nutrition in critically ill patients.
Clinical nutrition:
Included in specialized nutrition formulas for liver disease patients to support hepatocyte repair and reduce transaminase levels. Used in low-protein diets for chronic kidney disease patients to reduce metabolic load on the kidneys.
Personal care ingredient:
Added to skincare products (creams, masks) for its moisturizing and soothing properties, helping reduce redness in sensitive skin. Used in shampoos to repair damaged cuticles and enhance hair strength, formulated with cosmetic-grade materials.
Feed Industry
Livestock and poultry feed
In weaning piglet feed, it alleviates weaning stress–induced diarrhea and improves survival rates. In broiler finishing feed, it enhances feed conversion efficiency.
Aquaculture feed
Used in fish and shrimp nursery feed to improve stress resistance (e.g., against temperature fluctuations or poor water quality) and increase survival rates; suitable for high-value species such as whiteleg shrimp and bass.
Pet food
Added to senior dog and cat food to improve digestive absorption and reduce constipation.
