Functions of Ademetionine 1,4-Butanedisulfonate

Ademetionine 1,4-butanedisulfonate (SAMe-1,4-BDS) is a stable salt form of S-adenosylmethionine (SAMe), a naturally occurring compound in the human body. Its primary functions include:

1. Liver Health:Promotes hepatocyte regeneration and detoxification. Used to treat liver disorders (e.g., cirrhosis, hepatitis, cholestasis) by enhancing glutathione synthesis and reducing oxidative stress.

2. Neurological and Psychiatric Applications: Modulates neurotransmitter synthesis (e.g., serotonin, dopamine), supporting the treatment of depression, anxiety, and cognitive disorders.

3. Joint Health: Stimulates proteoglycan synthesis in cartilage, aiding in osteoarthritis management.

4. Enhanced Stability: The 1,4-butanedisulfonate salt improves SAMe’s stability and bioavailability, ensuring longer shelf life and better therapeutic efficacy compared to free SAMe.

 

China holds significant competitive advantages in producing SAMe-1,4-butanedisulfonate:

1. Scalable Production: Large-scale fermentation and chemical synthesis facilities support high-volume output to meet global demand.

2. Advanced Technology: Adoption of cutting-edge biotechnological processes (e.g., microbial fermentation, enzymatic conversion) ensures high-purity SAMe synthesis.

3. Supply Chain Integration: Well-established raw material networks (e.g., methionine, ATP precursors) reduce lead times and production costs.

Customization Capabilities: Flexibility to produce tailored formulations (e.g., injectables, oral tablets) for diverse clinical needs.
