Smartnutras — manufacturing for results
Encapsulation machine filling two-piece capsules
Capsule manufacturing

The most honest format in the category.

No flavor system to hide behind — a capsule is dose, purity and consistency. Which makes blend design, flow and fill weight control the entire game.

  • Single-ingredient and complex multi-ingredient blends
  • Capsule size mapping against your target dose
  • Stock catalog options and custom development
Overview

Where high-active formulas usually belong

When the dose is large, the actives are bitter, or the ingredient set is long, capsules are often the format that can actually carry the product. The tradeoff is that everything depends on the powder blend behaving predictably.

Our development work focuses on the unglamorous variables that determine quality: particle size and density, flow, segregation risk, moisture sensitivity, excipient selection and the relationship between fill weight and capsule size.

The result is a capsule that delivers the label dose in every unit — at bench scale and at production scale.

From blend to bottled capsule

Capsules look simple from the outside. Inside the program, dose-to-size fit, blend flow and count accuracy decide whether the product is easy or impossible to make.

Process

How the product gets made

A repeatable path from formulation to finished, packed units.

  1. 01

    Blend design

    Actives, excipients and flow agents selected for uniformity, density and capsule fit.

  2. 02

    Blending

    Controlled blending with uniformity verification so every capsule carries the same formula.

  3. 03

    Encapsulation

    Filling with in-process weight monitoring, then polishing and sorting.

  4. 04

    Bottling

    Counting, sealing, capping and labeling into your finished package configuration.

Formulation considerations

What we solve before production

The variables that decide whether this format works for your ingredient set.

  • Total fill weight vs. capsule size and swallowability

  • Segregation risk in multi-ingredient blends
  • Moisture-sensitive actives and shell interaction
  • Excipient minimization vs. process reliability
  • Overage strategy for actives with known degradation
  • Shell selection for vegan, halal or kosher positioning
  • Serving count and its impact on consumer compliance
