Project Description
Product Description
L-lysine is primarily produced through microbial fermentation (using microorganisms such as Corynebacterium glutamicum or Escherichia coli) of plant-based raw materials like corn starch and molasses.It is an essential amino acid that plays a critical role in protein synthesis, collagen formation, and immune function. It is commonly used to support overall health, promote wound healing, and enhance calcium absorption. As a building block for various proteins and enzymes, L-Lysine is vital for maintaining healthy skin, bones, and connective tissues. It is also known for its potential to support the immune system and manage occasional cold sores when taken as a dietary supplement.

Key Application Areas & Functional Benefits
1.Dietary Supplements & Functional Foods
As an essential amino acid, L-Lysine is a fundamental component in protein synthesis. It is widely used in the formulation of dietary supplements (capsules, tablets, and powders) and fortified foods and beverages to enhance their nutritional profile, particularly for products targeting overall wellness and specific nutritional needs.
2.Sports Nutrition & Muscle Health
L-Lysine plays a role in the body’s protein metabolism. It is therefore a common ingredient in sports nutrition products, including protein blends and recovery formulas, where it supports muscle protein synthesis and maintenance.
3.Bone Health Formulations
Due to its role in calcium absorption and metabolism, L-Lysine is included in formulations designed to support bone health. It is often combined with calcium and vitamin D in supplements aimed at maintaining bone density.
4.Skin, Hair, and Nail Health Products
As a precursor to collagen, L-Lysine is utilized in beauty supplements and topical formulations to support the structure and integrity of skin, hair, and nails.
5.Immune Support Formulations
L-Lysine is a common ingredient in immune health supplements, where it is included for its role in supporting overall immune function.
6.Clinical & Specialized Nutrition
L-Lysine is used in clinical nutrition products (e.g., medical foods, enteral nutrition) and specialized wellness formulations for its defined nutritional and metabolic functions.
Quality & Compliance Highlights
- Our L-Lysine product is manufactured to meet the highest industry standards for purity and quality. The assay content ranges from 98.0 to 102.0 percent as verified by HPLC, exceeding typical industry specifications. The product conforms to United States Pharmacopeia testing specifications, European Pharmacopoeia testing specifications, and Japanese Pharmacopoeia testing specifications, providing comprehensive regulatory compliance for global markets.
- Heavy metals are strictly controlled with total heavy metals limited to no more than 10 parts per million, lead content no more than 10 parts per million, and arsenic content no more than 1 part per million, meeting the strictest international safety requirements.
- For applications requiring higher analytical rigor, we offer bioreagent grade L-Lysine with additional testing for endotoxins (less than or equal to 0.1 EU per milligram at 1 percent solution), bioburden (less than or equal to 100 CFU per gram), and confirmed absence of DNase, RNase, and protease activity.
- Our L-Lysine is sourced from non-animal origin, making it suitable for vegetarian, vegan, and allergen-conscious formulations. Certified reference material is available with traceability to USP and Ph. Eur. primary standards.
- When properly stored in sealed containers in a cool, dry place, L-Lysine maintains a shelf life of 36 months. The product is hygroscopic and should be protected from moisture during storage and handling.
