Gelatin capsules are small, cylindrical containers made from gelatin, a substance derived from animal collagen. They are commonly used to hold powdered or liquid supplements and medications, making them easy to swallow. The capsules dissolve in the stomach, releasing their contents for absorption. These capsules come in two main types: hard and soft. Hard capsules are typically used for dry powders, while soft capsules are often used for oils or liquid formulations. Gelatin capsules are popular because they mask unpleasant tastes and odors, providing a convenient way to take various health products.
