South Korea’s lysine market is supported by compound feed, livestock productivity, functional nutrition and fermentation capability. Animal feed is the dominant application because lysine is the first limiting amino acid in many swine and poultry diets.

According to 24ChemicalResearch, the market was valued at USD 205.8 million in 2025 and is estimated at USD 215.9 million in 2026. It is projected to reach USD 316.5 million by 2034, representing a 4.9% CAGR during 2026–2034.

Lysine: Feed Nutrition and Fermentation

CJ BIO identifies L-lysine as a reference amino acid in modern animal nutrition and offers L-lysine HCl, liquid lysine and other specifications through fermentation-based production. Daesang states that it entered Korea’s lysine business in 1973 and resumed commercial lysine operations in 2015.

The Seoul Capital Area leads with an estimated 36% of 2025 revenue, reflecting the concentration of corporate headquarters, nutrition companies, feed formulators, importers and biotechnology R&D around Seoul and Gyeonggi.

What Is Driving Market Growth?

Compound feed demand is the primary structural driver. Lysine helps optimize amino-acid balance in swine and poultry diets, allowing formulators to reduce crude protein while maintaining performance. This can improve feed efficiency and lower nitrogen excretion.

Fermentation efficiency determines producer competitiveness. Commercial lysine is produced through microbial fermentation followed by purification, concentration and finishing. Process yield, sugar feedstock cost, energy use and downstream recovery affect unit economics.

China is a major global amino-acid production base, creating price competition for South Korean producers. Domestic suppliers differentiate through supply reliability, formulation support, sustainability and broader amino-acid portfolios. The report notes an October 2026 proposed joint venture between CJ CheilJedang and ADM covering major amino-acid production assets in the United States and Brazil.

Trends and Growth Opportunities

Low-protein feed formulation is increasing lysine intensity. Supplemental lysine helps meet amino-acid requirements while reducing excess protein, supporting feed-cost management and lower nitrogen excretion.

Supply-chain consolidation is reshaping global amino-acid production. The report describes the proposed CJ CheilJedang–ADM joint venture as an example of producers seeking scale, regional supply resilience and manufacturing efficiency.
