Advanced Delivery System

Solid-in-Liquid DUO CAP

A revolutionary capsule-in-capsule system that suspends a solid-filled inner capsule within a liquid-filled outer capsule. This dual-action delivery protects sensitive ingredients and unlocks new formulation possibilities.

How Solid-in-Liquid DUO CAPs Work

Our innovative capsule-in-capsule design features an opaque inner capsule containing the solid formulation. This is then suspended within a larger, transparent outer capsule filled with a functional liquid. This advanced structure ensures the ingredients remain separate and stable until a phased release in the digestive system.

This dual-capsule system allows for a two-stage release. The outer capsule dissolves first for rapid absorption of the liquid, while the inner capsule can be designed to release its solid contents later, offering targeted delivery and enhanced therapeutic outcomes.

Key Benefits

Advantages of our Solid-in-Liquid DUO CAP technology for both manufacturers and consumers

Superior Ingredient Protection

The solid-filled inner capsule protects sensitive ingredients like probiotics or botanicals from the outer liquid matrix, ensuring maximum potency and stability.

Enhanced Bioavailability

The outer liquid-fill can enhance the body's absorption of certain nutrients, while the inner capsule can be designed for targeted, sustained release of its solid contents.

Convenient Dual Dosing

Combining two distinct formulations in a single, dual-action capsule simplifies user regimens and improves compliance, delivering synergistic benefits in one go.

Engineered Release Profiles

The two-capsule design allows for engineered, dual-release profiles. Get immediate release from the outer liquid and a delayed or enteric release from the inner solid core.

Formulation Flexibility

Allows for the combination of ingredients that would otherwise be incompatible in a single formulation, expanding the possibilities for innovative dietary supplement compositions.

Striking Visual Appeal

The capsule-in-capsule aesthetic is visually impressive, communicating a premium, scientifically advanced product that builds consumer trust and brand recognition.
