In Japan, aging well is a daily practice

(健康寿命) Kenkō jumyō means the years you live in good health. The aim isn’t more years, but more good ones.

I was fascinated not only by its effectiveness, but by its beauty. It is truly a white jewel.

The Aging Well Circle

Our signature extract

A thousand-year ingredient, refined by Japanese research

Our institute’s High Sialic Technology turns natural nest into LASIAL™.

What is sialic acid?

Sialic acid is a glyconutrient found at the tips of the sugar chains that cover our cells. Few foods contain much of it, and natural swiftlet’s nest is one of the richest sources known.

*Published content comparisons; breast milk per Xie Q et al., Front Nutr, 2022. LASIAL™ carries 5.89× the sialic acid of ordinary nest extract (in-house). Not results in people.

Aging well starts with daily care

In Japan, aging well is built on small habits kept every day. BI-SU is made to be one of them.

One 12 g jelly stick a day. That’s the whole routine.

Tear, squeeze, done. Nothing to measure or prepare.

No mixing, no shaker, no capsules. Take it anywhere.

A cool, lightly sweet pineapple jelly. Best from the fridge.
