Capsules, often referred to as containers, are small, sealed units designed to hold various substances. They are commonly used in the pharmaceutical industry to deliver medications in a precise dosage. Capsules can be made from gelatin or plant-based materials, allowing for easy swallowing and digestion. In addition to pharmaceuticals, capsules are also used in the food industry for supplements and vitamins. They provide a convenient way to package and consume nutrients without the need for measuring or mixing. Capsules can come in different sizes and shapes, catering to various needs and preferences.
