High Assay Purity: The content of the main component (magnesium glycinate dihydrate) is over 98%. Sunjoy reduces the residue of byproducts. It meets your demands for supplement products in the global market.

Optimized Mg Content: Mg content ranges from 11% to 13%, which proves our product is fully chelated magnesium glycinate dihydrate. This means it has low free magnesium and leads to less gastrointestinal discomfort.

High Nitrogen Verification: Our powder has a high and stable nitrogen level. According to the COA result, it ranges from 12.5% to 13.4%. This proves glycine and magnesium are stably combined in our product.

Strict Heavy Metal Control: Sunjoy strictly controls overall heavy metal content to comply with applicable heavy metal limits under relevant global food and supplement regulations. With an ultra-low toxic content level, your final product meets the regulatory requirements of the worldwide market.

Step 1: Raw Material Inspection: Sunjoy applies high-purity Glycine (amino acid) and Magnesium Oxide (MgO) as ingredients. We inspect them strictly to ensure our product meets the food and pharmaceutical standards. 

Step 2: Solution Formulation: We add glycine to the purified water and make sure it is thoroughly dissolved. This generates a uniform environment for aqueous reaction and prepares for the further chelation reaction.

Step 3: Synthesis and Chelation: We add a specific amount of Magnesium Oxide powder into the solution prepared in the last step and synthesize the reaction under controlled temperature and agitation. 

In this step, two glycine molecules chelate with one magnesium ion. In this way, they form stable Magnesium Bisglycinate molecules.

Step 4: Filtration and Concentration: When the reaction is finished, we filter the solution and concentrate it. In this step, the unreacted insoluble impurities are removed, and the material concentration is increased.

Step 5: Crystallization: We transfer the concentrated solution into the crystallization tanks for static crystallization. In this step, the solution precipitates high-purity magnesium bisglycinate crystals. 

Step 6: Drying: The crystal material undergoes centrifugal drying to remove a large portion of water. Then it is transferred to the drying oven to remove the residual moisture. After these processes, the material meets the standard specifications.

Step 7: Crushing and Mixing: In this stage, we crush the dried crystal cakes into fine powder and blend them into a uniform condition.

Step 8: Magnetic Separation and Sieving: The powder passes through multiple processes of magnetic separation to eliminate potential ferromagnetic impurities.

Step 9: Packing and Metal Detecting: We pack the finished powder into the liners. The packed products are processed with the final metal detecting to ensure safety and purity.
