How does pureSummit work?

Structure of a Liposome:

Nature's Perfect Delivery Package

Chondroitin 4-Sulfate Molecules

Hydrophilic Core

Phospholipid Bilayer

The acidic stomach environment is a danger zone for the fragile yet powerful chondroitin molecule. 


Unlike other joint products which are typically obliterated in the stomach before absorption can occur, our Liposomal carrier particles wrap around our chondroitin to protect it from damage.

Stored safely in the core of the liposome, it arrives safely to the intestinal tract where it can be absorbed and take effect. At this time the lipids that the liposome is comprised of are also absorbed.


Lipids become nutrition for the brain, liver, and cells, as they are a critical component to the animal body.

Why is pureSummit unique?

Unlike most joint support supplements, pureSummit is scientifically formulated to produce effective, powerful, and lasting results... FAST!

Speed of Efficacy
Tired of hoping your animal family's supplement plan will pay off? Feel like you’re in a race against time to help them? PureSummit is designed to be effectively absorbed, benefiting your animals body in days, not months.

PureSummit is derived from the highest quality bovine cartilage, free from contaminants that may inhibit absorption, while most chondroitin supplements are derived from shellfish, a common allergen which can cause hypersensitivity.

Mode of Delivery
PureSummit uses a patented liposomal delivery system specifically designed to protect and deliver the chondroitin safely through the dangerous stomach environment, where most supplements break down. These liposomes are manufactured with lipids derived from the finest non-GMO sunflowers, without the degrading effects of heat or pressure.
