Lysine

Lysine (CAS 70-54-2), also known as DL-Lysine or (±)-Lysine in its racemic form, is an amino acid used in food, pharmaceutical, and personal care manufacturing.

Where is Lysine used?

• Food and nutrition: corrects amino acid deficiencies and improves protein quality in cereal-based products, protein powders, and animal feed
• Pharmaceuticals: buffering agent for tablet and injectable formulations
• Personal care: supports moisture retention in skin creams, serums, and hair conditioning products
• Nutraceutical blends and clinical nutrition products target specific dietary supplementation requirements.

Good to know: The L-form predominates in nutritional and pharmaceutical supply chains; the DL racemic form is for industrial and research applications.
