What Are Capsules?

Definition and Structure

Capsules are small, cylindrical containers—usually made of gelatin or plant-based materials—that enclose powders, liquids, or semi-solids for oral consumption. They dissolve quickly in the digestive tract, releasing their contents for absorption.

History and Development

Capsules date back to the 19th century and have evolved significantly with the development of vegetarian shells, time-release coatings, and clean-label innovations that cater to modern health-conscious consumers.

Types of Capsules Available Today

Gelatin Capsules

Made from animal collagen, gelatin capsules are common in pharmaceuticals and supplements. They’re smooth, tasteless, and dissolve quickly.

Vegetarian and Vegan Capsules

Made from hydroxypropyl methylcellulose (HPMC) or pullulan, these are suitable for those avoiding animal products.

Softgel vs. Hard Shell Capsules

• Softgels: Ideal for oils and fat-soluble nutrients like fish oil or vitamin D
• Hard Shell Capsules: Better for powders, blends, or DIY capsule making

How Capsules Work in the Body

Digestion and Absorption Process

Capsules dissolve in the stomach (or intestine if enteric-coated), allowing the active ingredients to be absorbed into the bloodstream.

Time-Release and Enteric Coating

Some capsules are engineered to release ingredients slowly over time or bypass stomach acid to deliver content directly to the intestines—improving efficacy and reducing side effects.

Benefits of Taking Capsules

Convenience and Portability

Capsules are small, lightweight, and easy to carry—perfect for busy lifestyles.

Taste Masking

They eliminate the often unpleasant taste of raw powders or herbal extracts.

Precise Dosage Control

Each capsule delivers a specific, consistent dose—ideal for tracking nutrient intake or medical prescriptions.

Are Capsules Better Than Tablets?

Bioavailability and Breakdown Time

Capsules generally dissolve faster than tablets, meaning quicker absorption and faster results.

Ease of Swallowing

Many people find capsules easier to swallow than large, chalky tablets. Gel capsules especially glide down easily with water.
