Capsule-type magnesium supplements have been welcomed by the market due to their convenience of consumption. Food-grade magnesium oxide is often filled inside capsule shells as a raw material for magnesium nutritional fortification. Messi Biology has been deeply engaged in the R&D and production of food-grade magnesium oxide, providing food-grade magnesium oxide powders tailored for capsule-filling processes.
Capsule products rely on powder filling, which places high demands on the flowability of the raw powder. Food-grade magnesium oxide can have its bulk density adjusted through specialized processes, preventing the powder from agglomerating. This ensures smooth feeding and discharging in automatic capsule-filling equipment, reduces filling weight differences, and guarantees a stable magnesium content in every capsule. With a high magnesium content, a smaller filling volume can meet nutritional requirements, making it convenient to control capsule specifications.
Capsule formula systems are generally matched with diluents and glidants. Food-grade magnesium oxide exhibits excellent chemical stability and good compatibility with excipients. It is less prone to chemical reactions during storage, reducing the risk of discoloration and caking of the capsule contents, thereby safeguarding product quality throughout its shelf life.
For health supplement capsule raw materials, impurity control and regulatory compliance are essential prerequisites. Food-grade magnesium oxide must comply with food additive standards, with strict limits on harmful impurities such as heavy metals. Messi Biology’s food-grade magnesium oxide features a complete set of qualifications, and each batch comes with a Certificate of Analysis (COA) report, making it suitable for health supplement registration and filing.
During the formula debugging stage, attention must be paid to the powder’s moisture-absorption characteristics. Food-grade magnesium oxide powder has a certain tendency to absorb moisture; therefore, production workshops need to control ambient temperature and humidity, and packaging should utilize moisture-proof solutions to prevent the capsule contents from dampness and caking. In the new product development phase, small samples can be requested first to conduct filling process tests.
When magnesium capsule manufacturing enterprises select magnesium sources, they evaluate powder flowability and compatibility stability. Food-grade magnesium oxide is well-suited for capsule-filling processes, serving as a mature and stable magnesium source in magnesium capsule formulations to support the production of capsule-based magnesium supplements.
