Opinions

Why is L-methionine priced higher than DL-methionine, and what drives the premium?

Buyers should watch CJ's capacity expansions and Chinese R&D progress. If fermentation yields double, the L-methionine premium could narrow sharply, reshaping feed formulation economics. For now, DL-methionine remains the cost-effective choice for poultry and swine.

How is China's L-methionine supply-demand balance evolving amid global capacity shifts?

Import data shows August 2025 methionine imports up 14% year-on-year, indicating China still relies on overseas supply despite domestic expansion. Track maintenance schedules at Ningxia Ziguang and New Hecheng—unplanned outages could spike prices further.

What role does L-methionine play in human nutrition and specialty supplements?

The nutraceutical angle is often overlooked. With global male fertility concerns rising, L-methionine demand in supplements could grow double-digits annually. Suppliers should explore partnerships with supplement brands to capture this premium niche beyond commodity feed markets.

Overview

L-Methionine (L-蛋氨酸, CAS 63-68-3) is a white crystalline powder with a density of 1.34 g/cm³ and a melting point of 284°C (dec.), readily soluble in water. It is the biologically active L-isomer of methionine, an essential amino acid that cannot be synthesized by animals and must be obtained through diet.

Feed: serves as the first limiting amino acid for poultry, high-yield dairy cows, and fish, and the second limiting amino acid for pigs, promoting growth and increasing lean meat yield.
Nutritional supplements: a key component in sperm formation and development, supporting normal sperm count and quality in male health products.
Pharmaceuticals: used in amino acid therapy for depression, as both L- and DL-methionine can elevate S-adenosyl-L-methionine levels in the brain.
Industrial synthesis: produced via chemical synthesis combined with fermentation, or through one-pot fermentation and enzymatic catalysis methods.

China's L-methionine market is expanding with demand growth, while production capacity release is being reasonably controlled. Recent research highlights one-pot biosynthesis approaches integrating O-succinylhomoserine fermentation with enzymatic catalysis, offering shorter production cycles than traditional two-step methods.

Key domestic producers:
Zhejiang University of Technology research team – developing one-pot fermentation and enzymatic catalysis routes.
