Hard capsules are a type of medication delivery system made from two pieces of gelatin or a similar material. They are designed to hold powdered or granulated substances, making them easy to swallow. Hard capsules can be filled with various contents, including nutritional supplements, herbal remedies, or pharmaceutical drugs. These capsules dissolve in the stomach, releasing their contents for absorption into the body. Hard capsules are popular because they can mask unpleasant tastes and odors, and they allow for precise dosing. They are also available in different sizes and colors, catering to various preferences and needs.
