This article provides a detailed overview of the various sizes of veggie capsules available, helping you choose the right size for your needs. We’ll cover capsule dimensions, filling capacity, common uses, and factors to consider when selecting the appropriate size for your supplements or other applications. Learn how capsule size impacts your product’s efficacy and overall user experience.

Veggie capsules, also known as plant-based capsules, come in a range of sizes, typically denoted by numbers (e.g., size 00, size 0, size 1, size 2, size 3, size 4). These numbers directly correlate with the capsule’s physical dimensions and, consequently, the amount of powder or liquid it can hold. Larger numbers indicate smaller capsules, while smaller numbers indicate larger capsules. This seemingly counter-intuitive numbering system is a historical convention within the industry.
| Capsule Size | Approximate Capacity (mg) | Approximate Length (mm) | Approximate Diameter (mm) |
|---|---|---|---|
| Size 00 | 750-800 | 25-28 | 8-9 |
| Size 0 | 500-600 | 23-25 | 7-8 |
| Size 1 | 400-500 | 21-23 | 6-7 |
| Size 2 | 300-400 | 19-21 | 5-6 |
| Size 3 | 200-300 | 17-19 | 4-5 |
| Size 4 | 100-200 | 15-17 | 3-4 |
Note: These are approximate values. Actual capacities may vary slightly depending on the manufacturer and the specific material of the veggie capsules.
Selecting the correct size depends on several factors:
The density of your powder will significantly impact how much fits into a given capsule size. Denser powders, like some herbal extracts, will fill a capsule more quickly than lighter powders. The flowability of your powder also influences filling efficiency; some powders are easier to fill into capsules than others.
Determine the amount of supplement needed per serving. This will directly influence the necessary veggie capsule size. If you have a small dose, you’ll need smaller capsules. If you have a larger dose, you’ll likely require a larger capsule size.
Larger capsules might be difficult to swallow for some individuals, while smaller capsules might lead to more capsules needing to be taken for the same dose. Consider your target audience and their preferences.
Finding a reliable supplier of high-quality empty veggie capsules is crucial. Many companies offer a variety of sizes and materials. For large-scale purchases, consider contacting a wholesale supplier such as SUQIAN KELAIYA INTERNATIONAL TRADING CO., LTD for competitive pricing and bulk discounts. Always ensure the capsules are made from reputable sources and meet appropriate standards.

Choosing the right size for your veggie capsules is essential for effective supplement delivery and a positive user experience. By carefully considering powder density, desired dosage, and swallowing ease, you can ensure your product is both effective and user-friendly. Remember to always source your capsules from a reputable supplier.
