Capsule filling is the process of placing powdered or liquid substances into capsules, which are small containers typically made of gelatin or plant-based materials. This method is commonly used in the pharmaceutical and dietary supplement industries to deliver medications or nutrients in a convenient form. The filling process can be done manually or with the help of machines, ensuring that each capsule contains a precise amount of the active ingredient. Proper capsule filling is essential for maintaining dosage accuracy and ensuring the effectiveness of the product, making it a critical step in the production of medications and supplements.
