Hard Capsules

Hard capsules are among the most popular and widely used dosage forms for food supplements. They are made of two prefabricated halves that are tightly sealed to prevent leakage at the seam. The solid shell of hard capsules can be composed of various materials, such as gelatin or HPMC (hydroxypropyl methylcellulose), a vegan-friendly alternative.  

Capsules effectively protect their contents from external influences like light and oxidation. With minimal or no pressure during filling and reduced thermal stress, they ensure the preservation of sensitive nutrients. Capsules dissolve in the stomach, ensuring precise ingredient release, making them an excellent option for bitter-tasting or sticky herbal formulations. Additionally, capsules are less irritating to mucous membranes, are easy to swallow, and offer simple and accurate dosing. Being odorless and tasteless adds to the many advantages. Capsules are also ideal for “clean” formulations, free from additives, aligning with the growing trend of clean and natural labeling.
