Custom Capsule Manufacturing

Your Custom Nutraceutical Capsule Manufacturer

SMP stands for Supplement Manufacturing Partners. Our team is dedicated to be your partner in most efficiently manufacturing your growing vitamin business to scale.

Before encapsulation, your formula must be blended to ensure even distribution of ingredients in each capsule.


Once all ingredients in your formula are blended, they are filled in capsule shells. We offer to encapsulate it in gelatin, vegetable and pullulan capsule shells.

Polishing & Inspection

Each capsule is polished of any excess powder for a clean finished look and triple inspected for any defects.


After capsules are manufactured, post-inspection, we run identity, potency, micro, and heavy metal tests to ensure pharmaceutical grade quality.

Custom Capsule Manufacturing:

Capsules have been a very reliable and widely accepted method form of encapsulation for nutraceutical formulas. You can have your formula blended and encapsulated into a capsule with little to no effort with the help of us.

Capsule Blend Preparation Process

As capsules are produced, plenty of work behind the scenes must be done before the capsule is ready to be bottled. The powder within capsules can be prepared in two ways: 

  1. Wet Granulation Process
  2. Dry Granulation Process 

Wet Granulation Blend Capsule Manufacturing

During the wet granulation process, you begin with the blend for the supplement ready and mixed. Then the mixed blend will then have water added to it.

The water will wet the powder and add an immobile layer of water between particles. With more and more water being added to the powder, it will continually grow the layer of water gets wider and will ultimately pass through the pores of the particles. 

To then get the water out of the blend, it will be evaporated and will result in a very strong level of adhesion for the particles, which will result in the particles grouping in and becoming larger. The size of particles will be affected by many factors such as blend, density, and the type and amount of binders added are a few of those. 

The final step will be drying. For small batches, a tray drying oven is used, but for more automation and larger batches, fluid bed dryers are used. These driers utilize a stream of warm and dehumidified air running through the base of the drying chamber. To keep the powder from being pushed out of the chamber, a fine mesh is in place to keep all powder where it needs to be.

Dry Granulation Blend Capsule Manufacturing 

The process of dry granulation is commonly used when the blend being used does correctly work or operate as intended when met with moisture and heat.

The main difference in this process is the fact that liquids are never introduced to the blend. With the prepared blend of ingredients, the powder will be fed into a machine that will apply immense pressure and force to make the powder more compact and increase the bulk density. The amount of force needed varies depending on the blend, its ingredients, and the desired density.

Encapsulation Process

Manufacturing a nutraceutical capsule is a process that takes many steps to make perfect.

When producing these capsules, the materials must be gathered. Once all materials are prepared, they are joined with hot demineralized water and mixed via vacuum, in a machine. Over time, the blend will have more hot water added, dyes and opacifants if needed. When ready, the mixture will be molded around steel pins into the correct size and shape of the capsule. Both ends of the capsule are then dried together. The level of the temperature and humidity are monitored to correctly allow for optimal drying of the capsules. 

After the process of preparing and drying the capsule, the cap and body will be trimmed to a .15 mm tolerance. The capsules are put together and are ready to be filled and sent out.

Capsule Shell Choices

Capsule shells are distinguished between two categories:

Gelatin capsule

Vegetarian capsule

Gelatin Capsules

Gelatin is made from animal by-products derived from beef only such as bovine or cows.

The part in which it comes from is called the collagen, which is the soft protein that connects the skin, bones, muscles, and tendons of the animal. A slew of potential health benefits come with the gelatin shell since it contains protein and two amino acids; Glycine and Proline.

Vegetarian Capsules

When dealing with vegetarian capsule shells, there are two main variations:

  1. Hypromellose

  2. Pullulan

Hypromellose, officially known as Hydroxypropyl Methylcellulose (HPMC), only contains HPMC and purified water. This option includes no preservatives, animal by-products and is GMO-free, gelatin-free, gluten-free, starch-free and BSE free.

The other veggie capsule shell option is Pullulan. Pullulan is a water-soluble polysaccharide produced by the fermentation of starch/sugar by the fungus Aerobasidum pullulans. It is 100% natural, starch-free, gluten-free, preservative-free, and GMO-free. Unlike HPMC, Pullulan is 100% natural because it is not produced by any chemical modification.
