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.

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.

Sialic acid vs royal jelly
Natural swiftlet’s nest, per 100 g*

Researched with Kyushu University · Azabu University
*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.
