S-Adenosyl-L-Methionine Powder

S-Adenosyl-L-Methionine Powder - Premium Grade from Leading Manufacturer

Shaanxi Hongda Phytochemistry Co., Ltd. is a reliable manufacturer and supplier of high quality S-Adenosyl-L-Methionine Powder, providing you exceptional stability, purity and bioactivity for pharmaceutical and nutraceutical uses. Since our founding in 2001, we have been pioneers in developing sophisticated stabilisation methods that solve the central problem of the industry: the inherent instability of this sulfonium molecule. Our factory direct advantage provides you with high potency material that keeps its active (S,S)-diastereomer integrity during storage and processing. Our therapeutically effective formulations are guaranteed by our state of the art 100,000 level purification workshops, cGMP certification and moisture barrier Packaging methods.

Product Introduction

Our product is made in the disulfate tosylate salt form with 99% purity by HPLC analysis. This off-white crystalline powder is the stabilised industrial grade of nature’s universal methyl donor, formulated to mitigate the quick degradation problems. It has good compressibility for the production of tablets, low hygroscopicity under suitable storage conditions and long-term chiral stability . Each batch is tested intensively on appearance, moisture content, heavy metals and microbiological contamination before release, so you obtain pharmaceutical grade material ready for direct formulation into capsules, tablets or parenteral formulations.

Third-Party Test Report

Independent Verification: To support our quality claims, we send our goods to third-party laboratories SGS and Eurofins for analysis. These reports confirm the conformity with the international pharmacopoeia standards.

Pesticide Residue Testing: Multi-residue screening tests for more than 500 pesticide chemicals using GC-MS/MS and LC-MS/MS technology, non-detect findings within the limits of EU legislation for pharmaceutical raw materials.

S-Adenosyl-L-Methionine Powder Advantages

Better Stability Profile: Our innovative stabilisation procedure maintains >95% potency for 24 months under controlled storage circumstances, compared to unstabilized versions that decay within weeks. The longer shelf life means less risk to your inventory and less waste in production.

High Bioavailability Design: The disulfate tosylate salt form shows 70-80% enteric absorption rates, which is much higher than conventional salt forms. Your formulations provide steady plasma levels thereby boosting therapeutic efficacy and decreasing the dosage quantity.

Superior Compressibility: Particle size distribution optimised and low moisture content allows direct compression tableting without the use of large quantities of binders. High tablet hardness > 8 kp with fast disintegration profile can be obtained.

S-Adenosyl-L-Methionine Powder Application

Neurological Health Formulations: Our powder is used as an active ingredient in mood-support supplements and prescription antidepressants that target neurotransmitter synthesis, including serotonin and dopamine production. as general, the formulator will include 400-800 mg/dose as enteric-coated tablets to avoid breakdown in the stomach.

Liver Support Products: The product is a glutathione precursor for hepatoprotective use for intrahepatic cholestasis and toxic liver injury. Your formulations are useful for people with chronic liver diseases with enhanced methylation capability and membrane phospholipid synthesis on standard doses of 600-1200 mg daily.

Production Process

Step 1 - Fermentation Initiation Choose specialised yeast strains optimised for high SAMe production, culture in controlled bioreactors with optimal levels of methionine and ATP.

Step 2 - Cell Harvesting and Lysis: Collect biomass via continuous centrifugation, then apply enzymatic lysis under pH-controlled conditions to release intracellular SAMe while minimizing racemization.

Step 3 - Purification and Salt Formation: Several times chromatographic separation by ion exchange resins and crystallise the product with p-toluenesulfonic acid and sulphuric acid to obtain the stable disulfate tosylate salt.

Step 4 - Drying and Micronization: Vacuum dry at controlled temperature (40°C) and then jet mill to obtain accurate particle size distribution.

Step 5 - Quality Testing and Packaging: Perform detailed analytical testing per COA criteria. Package in triple layer moisture barrier bags with nitrogen flushing under ISO Class 7 cleanroom settings.

OEM/ODM Support

Formulation Development: Our R&D team works with you to create proprietary blends by combining S-Adenosyl-L-Methionine Powder with synergistic substances such as B-vitamins, trimethylglycine or herbal extracts. We can give you stability testing data and bioavailability optimisation for your specific formulations.

Flexible Dosage Form Manufacturing: We have production lines capable of many formats including enteric-coated tablets, vegetarian capsules, effervescent powders and lyophilised injectables. We do batches from 10,000 to 5,000,000 pieces with quality control throughout.

Private Label Package Solutions: Choose from standard bottle designs or create bespoke package graphics that represent your brand personality. We can package your product in blister cards, amber glass bottles, aluminium sachets and child resistant closures that meet regional labelling requirements.
