How the Body Processes Actives

First-Pass Metabolism

First-pass metabolism occurs when swallowed ingredients travel through the digestive system and liver before reaching general circulation.

Core Concept

What does it mean?

During this process, part of an active ingredient may be transformed or broken down before it becomes available to the rest of the body.

The Challenge

Oral delivery can reduce active availability

Digestive conditions, poor dissolution, and liver metabolism can reduce the amount of unchanged active ingredient entering circulation.

The Nano Approach

Delivery design can influence performance

Nano delivery may support improved dispersion and more efficient uptake pathways, helping formulations make more effective use of the active ingredient.

Key Principles

How delivery science affects finished-product performance

Dispersion

Smaller delivery structures can distribute more evenly throughout compatible liquid and solid formulations.

Surface Area

Reducing particle size increases the available surface area of the active delivery system.

Uniformity

Controlled particle distribution supports consistent active concentration across the finished batch.

Stability

Properly designed delivery systems can help reduce settling, separation, and inconsistent product appearance.

Measurement Matters

Nano performance should be supported by data

Particle size, distribution, stability, potency, and application performance should be evaluated using appropriate technical testing rather than relying only on marketing terminology.
