What You Need
To fill capsules effectively in 2025, you’ll need the following:
-
Empty Capsules: Available in gelatin or vegan (HPMC) form. Common sizes are 00, 0, and 1.
-
Capsule Filler Machine: Manual or semi-automatic models are widely available and affordable.

Powder Tamper: Helps compress powder for more accurate filling.

Step-by-Step: How to Fill Capsules
1. Choose Your Capsule Size
Size 00 holds approximately 400-600 mg of powder, while size 0 holds 300-500 mg. Match your dosage requirements with the appropriate size.
2. Prepare Your Powder
Ensure your powder is finely ground and dry. Clumpy or moist powder will not fill evenly and can degrade capsule quality. You can sift or grind it further if needed.
3. Set Up Your Capsule Machine
Place the capsule filler on a clean, dry surface. Insert the bottom halves of the capsules into the machine. Most machines hold 50 to 100 capsules at once.
4. Fill With Powder
Spread your supplement powder evenly over the capsules using a spatula or scoop. Use the tamper tool to compress the powder, then repeat the filling until each capsule is full.
5. Attach the Tops
Place the capsule tops into the alignment tray. Close the machine to join the capsule halves securely.
6. Inspect and Store
Remove completed capsules, inspect for defects, and store them in an airtight container away from heat and moisture.
