Imagine waking up every day and moving with ease — without that stiffness or discomfort in your joints that seems to come with age.

In the mountains of Japan, there’s a small village called Yuzurihara…
There, men and women in their 70s, 80s, and even 90s spend hours squatting, planting rice, and harvesting vegetables by hand — something unthinkable for many people of the same age.

The difference is in their diet.
The fertile soil of the region grows a unique type of purple sweet potato called satsumaimo, rich in hyaluronan — a molecule that hydrates, nourishes, and lubricates the joints.

Research shows that after age 30, our bodies start losing hyaluronan rapidly.
This leaves synovial fluid — which should be thick and protective — thinner and drier.
The result? Cartilage becomes exposed, discomfort increases, and flexibility decreases.

In Yuzurihara, regular consumption of this molecule keeps synovial fluid healthy, cartilage protected, and joints flexible well into old age.

Today, thanks to this discovery, an advanced formula can concentrate this same molecule and help maintain joint comfort for much longer.
