H2: Choosing the Right Capsule Size for Your Product

H3: 1. Ingredient Type and Density

Different ingredients have different densities. For instance, herbal powders tend to be lighter, meaning that you may need a larger capsule to accommodate the same dose compared to denser powders like vitamins or minerals. Use the weight capacity listed in the capsule size chart to help guide your decision.

H3: 2. Dosage Requirements

Determine the desired dose per capsule for your product. This will help you choose the capsule size that can hold the correct amount of your ingredient.

H3: 3. Target Audience

If your product is designed for children or the elderly, smaller capsules like sizes 3, 4, or 5 are preferable since they are easier to swallow. On the other hand, if you are formulating supplements for adults, larger capsules like size 0 or 00 might be ideal.

H3: 4. Filling Machine Compatibility

Ensure the capsule size you choose is compatible with your capsule filling machine. The YITI Capsule Filling Machine, for instance, is designed to work with size 00 capsules, making it an excellent choice for most supplement manufacturers.
