Empty hard capsules, as a critical dosage form in the pharmaceutical and health supplement industries, are widely utilized for their ability to deliver solid and liquid formulations effectively. Composed primarily of purified gelatin and supplementary excipients, these capsules address challenges related to palatability and ease of ingestion, thereby enabling patient compliance and fulfilling the principle that Good Medicine Taste Less Bitter.

In the pharmaceutical sector, demand for empty hard capsules is driven by their functional advantages in taste and odor masking, as well as protection of active pharmaceutical ingredients (APIs). Many APIs exhibit strong bitterness or pungent odors, which can hinder patient adherence—particularly among pediatric and dysphagia-prone populations. Encapsulation significantly improves acceptability and compliance. Furthermore, capsules provide a protective barrier against environmental factors such as light, moisture, and oxidation, ensuring drug stability and efficacy throughout the product’s shelf life. Advances in formulation technology have led to specialized variants, including enteric-coated capsules, which enable targeted release in the intestinal tract. This minimizes gastric irritation and enhances bioavailability, meeting increasingly sophisticated therapeutic requirements.

Within the health supplement market, demand is shaped by consumer preferences for convenience, precise dosing, and lifestyle compatibility. In an era characterized by fast-paced living, capsules offer a portable, easy-to-administer, and accurately dosed delivery method for nutrients such as vitamins, minerals, fish oil, and probiotics. Their use supports efficient daily supplementation routines. Moreover, the introduction of plant-based alternatives—such as hydroxypropyl methylcellulose (HPMC) capsules—accommodates dietary restrictions associated with vegetarianism and religious practices, reflecting broader trends toward market inclusivity and personalization.
Market analysis indicates that the global hard capsule market is projected to reach USD 1.24 billion (approximately CNY 8.954 billion) by 2025, with the Chinese market accounting for USD 322 million (CNY 2.329 billion). Growth is expected to continue through 2032, underscoring the expanding role of empty hard capsules across both industries. Technological innovation and rising health consciousness are key drivers of this sustained expansion.

In summary, the pharmaceutical industry values empty hard capsules for their contribution to safety, efficacy, and stability in drug delivery, while the health supplement sector leverages them to meet evolving consumer expectations for convenience, variety, and user experience. Going forward, ongoing advancements in material science and increased public awareness of preventive healthcare will further solidify the role of empty hard capsules as a vital interface between health products and end users.
