Applications of Hard HPMC Vegetarian Capsules in Food Supplements

In the world of dietary supplements, ensuring the efficacy, safety, and convenience of products is paramount. One of the key components in the formulation of these supplements is the choice of encapsulation. Hydroxypropyl Methylcellulose (HPMC) capsules have emerged as a popular choice due to their numerous benefits. In this blog post, Wecaps will share the applications of hard HPMC capsules in food supplements.

Hard HPMC capsules are pre-gelatinized and are used to encapsulate powders, granules, or liquids for various applications. Capsules can be customized in size and shape to suit specific formulations.

Types of Hard HPMC Capsules

1. Clear Capsules: These provide a transparent view of the encapsulated supplement, showcasing the product's quality.

2. Opaque Capsules: They protect light-sensitive ingredients from degradation.

3. Colored Capsules: Used for branding purposes and to distinguish between different formulations.
