Empty Capsules

Empty Capsules, which are widely used in pharmaceuticals, supplements, and herbal medicine.

What are Empty Capsules

• Empty capsules are shells made of gelatin or vegetarian material that can be filled with powders, granules, or oils.
• They provide an easy way to consume supplements or medicine without tasting the raw ingredients.
• They come in different sizes, colors, and materials depending on use.

Types of Empty Capsules

1. Gelatin Capsules (standard type)

• Made from animal collagen (usually bovine or porcine).
• Smooth, tasteless, easy to swallow.
• Dissolve quickly in the stomach.

2. Vegetarian Capsules (HPMC or pullulan)

• Made from plant cellulose (hydroxypropyl methylcellulose) or fermented tapioca (pullulan).
• Suitable for vegans, vegetarians, or people avoiding animal products.
• More stable against heat and humidity.

3. Special Capsules

• Enteric-coated capsules: Resist stomach acid → release contents in intestines.
• Delayed-release capsules: Timed release for steady absorption.
• Liquid-filled capsules (softgels): Pre-filled with oils, vitamins, or herbal extracts.

Capsule Sizes

• Capsules are available in different sizes (from 000 = largest to 5 = smallest).
• 000: Holds 1000 mg powder (very large, hard to swallow).
• 0: Holds 400–500 mg powder (common supplement size).
• 1–3: Smaller doses, easier to swallow.
• 4–5: Very small (for children, pets, or potent medicines).

Benefits of Using Capsules

• Mask taste & odor: Bitter herbs or supplements become easier to take.
• Controlled dosing: Precise measurement of powders.
• Easy to swallow: Smooth surface helps compared to tablets.
• Custom formulations: Allows DIY herbalists, nutritionists, or pharmacists to create unique blends.
• Faster absorption: Capsules dissolve quickly compared to some tablets.

Things to Keep in Mind
