A capsule is a small container designed to hold substances, often used in pharmaceuticals to deliver medication. Capsules can be made from gelatin or plant-based materials and are typically filled with powder, liquid, or granules. They are easy to swallow and can mask the taste of the contents, making them a popular choice for both prescription and over-the-counter drugs. In addition to pharmaceuticals, capsules are also used in the food industry, such as for dietary supplements and vitamins. They provide a convenient way to consume nutrients while ensuring accurate dosing. Capsules can also be found in various forms, including soft gels and hard shells, catering to different needs and preferences.
