Empty pill capsules are commonly used in oral dosage forms to hold powdered herbal supplements, vitamins, or APIs. They come in several sizes to meet different needs and preferences. Some are animal-based, made with collagen-like connective tissue from beef or pork, while others are vegetable-based, made with starch or hydroxypropylmethylcellulose.

These capsules are easy to use, convenient, and economical. They are especially useful for substances that have an unpleasant odor or taste. The global empty pill capsules market is expected to grow at a rapid pace during the forecast period. Increased awareness regarding preventive medicine and the rising incidence of various diseases are two of the major factors contributing to the growth of the industry. In addition, the convenience of empty pill capsules is expected to further increase the use of empty pill capsules in the pharmaceutical and nutraceutical industries.

Glucosamine-based empty pill capsules have a long history of use in pharmaceuticals and nutraceuticals. Since the gelatin is widely available, manufacturers can use it for various applications in different industries. Glucosamine-based capsules are common in the medical industry, since glucosamine is a natural component of cartilage. It is easily digestible and free of side effects.

While many prescription medications are still in liquid form, pill capsules have been revolutionized by introducing an easier-to-dose alternative. With the emergence of gel capsules, this solution is proving to be a great convenience. Traditionally, gel capsules have been filled with powder or liquid medication, but their method of dosing made it difficult and messy. However, empty pill capsules have made these problems a thing of the past. Nowadays, even cough medicines come in convenient pill capsules.
