The Science

What Is Curcumin?

The hero in Kurk is curcumin, a compound that makes up only around 3% of the turmeric root. This potent and biologically-active compound offers extensive health benefits.

Historically, the body's absorption of curcumin has been limited, which has reduced its full potential. But with Kurk, that’s no longer the case - with increased absorption, we've unlocked the full power of curcumin.

Curcumin is a crystal
Noted for its vibrant yellow-orange colour, the curcumin crystal is a moderately hard structure, and is insoluble in water - making absorption very difficult.
Curcumin in micelles
Kurk uses plant-based ingredients to create micelles to surround the hard crystal which allows it to effortlessly mix with water - and be absorbed) into the cell wall. These tiny structures carry curcumin into your bloodstream effectively.
