# How to Build Tiny Lipid Carriers for Delivering Nutrients

> A method for creating tiny, 20-60 nanometer lipid-based particles designed to carry vitamins and nutrients into the human body more effectively.

- **Patent:** US 9925149
- **Original title:** Nanoparticle compositions and methods as carriers of nutraceutical factors across cell membranes and biological barriers
- **Owner:** Nanosphere Health Sciences
- **Granted:** 2018
- **Status:** Active
- **Times cited:** 10
- **Field:** biotech, pharmaceutical

## What it does

This patent describes a specific manufacturing process to create lipid structural nanoparticles, which act as tiny delivery vehicles. The method requires combining essential phospholipids and fatty acids using at least three distinct production techniques, such as high-pressure homogenization and ultrasonication. By using these specific combinations, the process creates particles between 20 and 60 nanometers in size. These particles are then loaded with nutraceuticals or vitamins to help them cross biological barriers in mammals.

## What it does NOT cover

- Does not cover delivery systems larger than 60 nanometers.
- Does not cover methods using fewer than three of the listed production techniques.
- Does not cover the chemical composition of the nutraceuticals themselves, only the carrier system.
- Does not cover non-lipid based nanoparticle delivery vehicles.

## The clever bit

The innovation lies in the mandatory use of a triple-process manufacturing sequence, which ensures the resulting lipid particles are consistently small enough (20-60nm) to effectively penetrate biological membranes.

## Real-world examples

1. Liposomal vitamin C supplements
2. Nano-encapsulated nutraceutical powders
3. Enhanced absorption dietary supplements

## Why it matters

Improving the bioavailability of nutrients is a major goal in the health and wellness industry. By creating a standardized way to package supplements into tiny lipid spheres, this technology aims to ensure that vitamins and other compounds are better absorbed by the body rather than being broken down prematurely.
