Key Advantages of Capsule Supplements
Superior Taste Masking
Completely encapsulates bitter or strong-tasting ingredients such as herbal extracts, making products much more consumer-friendly.
Precise Dosing & Uniformity
Real-time weight monitoring during production ensures every capsule meets exact dosage specifications with minimal variation.
Enhanced Stability & Shelf Life
Protects sensitive active ingredients from moisture, oxygen, and light, preserving potency throughout the product’s shelf life.
Consumer Convenience
Easy to swallow, portable, and professionally presented — building immediate trust and improving compliance.
Whether you are launching a new brand or expanding an existing line, our contract encapsulation services deliver consistent quality at competitive pricing — typically 30%–60% more cost-efficient than many industry peers.
3. Advanced Shell Selection: Gelatin vs Vegan (HPMC) vs Pullulan
The capsule shell is far more than just a container — it is a critical protective barrier that directly impacts ingredient stability, dissolution profile, shelf life, and consumer perception. Terrawell offers a full range of high-quality shell materials tailored to your formulation chemistry and target market preferences.
Gelatin vs. Vegan Capsules: Detailed Comparison
| Feature | Bovine Gelatin | HPMC (Vegan) | Pullulan (Premium Vegan) |
|---|---|---|---|
| Raw Material Source | High-quality Bovine Collagen | Pine-derived Cellulose | Natural Fermentation of Tapioca |
| Dietary Compliance | Non-Vegan | 100% Vegan / Vegetarian | 100% Vegan / Vegetarian (Organic compatible) |
| Moisture Content | 13% – 16% | 4% – 6% (Low moisture) | Very Low |
| Oxygen Barrier | Moderate | Moderate | Excellent (up to 250 times better than HPMC) |
| Release Speed | Fast / Immediate Release | Customizable | Good + Superior Protection |
| Best For | Cost-sensitive products, standard supplements | Moisture-sensitive ingredients (probiotics, herbal extracts), clean-label brands | Premium formulas, oxidation-sensitive actives, high-end positioning |
| Relative Cost | Lowest | Medium | Highest |
Expert Recommendation: If your formula contains hygroscopic or moisture-sensitive ingredients such as probiotics, enzymes, or certain herbal extracts, we strongly recommend HPMC or Pullulan shells. Their significantly lower moisture content helps prevent shell brittleness and maintains full potency throughout the shelf life.
Specialized Delivery Technologies
- Delayed Release (Acid-Resistant / Enteric): Ideal for probiotics, enzymes, and acid-sensitive ingredients that need to bypass the stomach and release in the intestines.
- Liquid-Filled Hard Capsules: Combines the superior bioavailability of liquids with the branding flexibility and stability of hard capsules.
- Multi-Phase Beadlets: Visually attractive clear capsules containing time-released beads for both immediate and sustained nutrient delivery.
4. Capsule Sizes & Fill Weight Specifications
Selecting the correct capsule size is crucial for accurate dosing, manufacturing efficiency, and consumer experience. Terrawell’s engineering team performs tapped density testing on every new formulation to recommend the optimal size that balances fill weight, swallowability, and production stability.
Standard Capsule Size & Capacity Chart
| Capsule Size | Volume (ml) | Locked Length (mm) | Outer Diameter (mm) | 0.6 g/ml (mg) | 0.8 g/ml (mg) | 1.0 g/ml (mg) | Common Applications |
|---|---|---|---|---|---|---|---|
| 000 | 1.37 | 26.14 | 9.97 | 822 | 1,096 | 1,370 | High-dose formulas, fiber, amino acids |
| 00 | 0.91 – 0.95 | 23.30 | 8.53 | 546 – 570 | 728 – 760 | 910 – 950 | Multivitamins, standard supplements (most popular) |
| 0 | 0.68 | 21.70 | 7.64 | 408 | 544 | 680 | General use, moderate doses |
| 1 | 0.50 | 19.40 | 6.91 | 300 | 400 | 500 | Easier to swallow, moderate potency |
| 2 | 0.37 | 18.00 | 6.35 | 222 | 296 | 370 | Lower doses, children’s or sensitive formulas |
| 3 | 0.30 | 15.90 | 5.82 | 180 | 240 | 300 | Small doses, specialty products |
| 4 | 0.21 | 14.30 | 5.31 | 126 | 168 | 210 | Very low dose or compact formulas |
*Actual fill weights vary based on powder flow characteristics, particle size, and encapsulation equipment settings. Our team will validate and optimize the best size during the R&D phase.
One of the most common challenges in capsule manufacturing is under-filling or over-filling, which can affect product quality and production efficiency. Terrawell’s engineering team conducts comprehensive tapped density testing on every new formulation to ensure the chosen capsule size comfortably accommodates the required dosage while maintaining shell integrity and consumer appeal.
5. Specialized Capsule Technologies
For advanced formulations, Terrawell offers precision-engineered capsule technologies that go beyond standard immediate-release capsules to deliver targeted benefits and superior consumer experience.
- Delayed Release (Acid-Resistant / Enteric Capsules): Designed to protect sensitive ingredients like probiotics, enzymes, and certain herbal extracts from stomach acid, ensuring they reach the intestines for optimal absorption.
- Liquid-Filled Hard Capsules (LFHC): A hybrid solution that combines the high bioavailability of liquid formulations with the stability, branding options, and ease of swallowing of traditional hard capsules. Ideal for oil-based nutrients and fat-soluble vitamins.

8. Packaging Solutions & Bottling Integration
How your product is packaged directly affects ingredient stability, brand perception, shipping costs, and consumer experience. Terrawell offers flexible primary packaging options optimized for protection and efficiency.
Primary Packaging Pathways
- High-Density Bottles (HDPE / PET) — Available in amber, white, or clear with child-resistant or induction-sealed caps. Excellent moisture and light protection.

- Bulk Supply — Finished capsules packed in double-lined pharmaceutical-grade bags inside heavy-duty cartons, ready for your own downstream packaging lines.
Optimized Bottling Configurations
To prevent excessive headspace (which can accelerate oxidation) or capsule crushing during transport, we use standardized bottling ratios. For example, a 60-count bottle of Size 00 capsules typically requires a 150cc to 200cc container. Our team optimizes these configurations to reduce shipping volume, lower costs, and minimize environmental impact.
