Holy Basil, commonly known as Tulsi, is one of the most popular herbs used in traditional wellness supplements. Whether you are encapsulating pure Holy Basil powder, dried leaf powder, or a concentrated extract, choosing the correct capsule size helps ensure the desired dosage while keeping capsules easy to swallow.
This guide explains the best capsule sizes for Holy Basil (Tulsi), estimated fill weights, and which capsule size is most suitable for different applications.
What Is Holy Basil (Tulsi)?
Holy Basil (Tulsi) is an aromatic herb traditionally used in Ayurvedic practices and is often consumed as tea, powder, extracts, and capsules. The powdered form is commonly encapsulated because it provides a convenient way to take measured servings without dealing with the strong herbal taste.
Because Holy Basil powder is relatively light compared to minerals and dense extracts, capsule fill weights can vary depending on:
- Powder density
- Particle size
- Moisture content
- Manufacturing process
- Whether the ingredient is a powder or concentrated extract
Best Capsule Sizes for Holy Basil Powder
| Capsule Size | Approximate Capacity (Holy Basil Powder) | Typical Use |
|---|---|---|
| Size 000 | 800–1200 mg | High-dose formulations |
| Size 00 | 550–900 mg | Most popular choice |
| Size 0 | 400–700 mg | Standard daily use |
| Size 1 | 300–500 mg | Easier-to-swallow capsules |
| Size 2 | 200–400 mg | Lower-dose supplements |
For most Holy Basil supplements, size 00 capsules provide the best balance between capacity and ease of swallowing.
Why Size 00 Capsules Are Usually Recommended

Benefits of size 00 capsules include:

If your target serving is around 500–900 mg per capsule, size 00 is typically the preferred option.
Holy Basil Extract vs Holy Basil Powder
The required capsule size depends on whether you are encapsulating raw powder or a concentrated extract.
Holy Basil Powder
Raw powder generally requires larger capsules because the ingredient occupies more space.
Typical choices:
- Size 00
- Size 0
- Size 000 for larger doses
Holy Basil Extract
Concentrated extracts are denser and may require smaller capsules.
Typical choices:
- Size 0
- Size 1
- Size 2
Always perform a test fill when using a new ingredient, as density can vary significantly between suppliers.

How Much Holy Basil Fits in Each Capsule Size?
The exact amount depends on powder density, but the following estimates are commonly used:
| Capsule Size | Approximate Fill Weight |
|---|---|
| 000 | 800–1200 mg |
| 00 | 550–900 mg |
| 0 | 400–700 mg |
| 1 | 300–500 mg |
| 2 | 200–400 mg |
Finely ground powders generally achieve higher fill weights than coarse powders.
Tips for Filling Holy Basil Capsules
If you are filling capsules yourself, these tips can help improve consistency:
Use Finely Ground Powder
Fine powder flows better into capsules and helps achieve a more uniform fill.
Tamp Between Layers
Tamping allows additional powder to settle into the capsule body, increasing capacity.
Weigh Test Capsules
Use a precision scale to verify the actual fill weight of your capsules.
Store Properly
Keep powder and empty capsules in a cool, dry environment away from moisture.
Use Quality Capsules
High-quality capsules reduce breakage and improve filling efficiency.
