Background & Concept
This product was jointly developed as part of the Fermentation and Longevity Fund, a thematic initiative centered on health and fermentation. Regenesome has been advancing next-generation aging-care solutions by merging modern science with traditional ingredients, backed by health data analysis in partnership with Japan System Techniques Co., Ltd., and collaborative research with healthcare-related enterprises.
In this collaboration, the focus was placed on “fermentation”—a shared element between sake and supplements—to create a set that delivers both delight and wellness.
Features of the SAISEI Regenesome Supplement
Combining biotechnology with traditional Japanese ingredients, the supplement contains:
- Euglena gracilis: A nutrient-rich edible microalga with 59 types of nutrients
- Sake Lees Powder: Rich in amino acids and peptides from koji mold and yeast
- Kalahari Melon Extract: Known for its antioxidant and moisturizing properties
- Ergothioneine: A rare amino acid with strong antioxidant potential
The concept behind this product is to deliver a “triple SAISEI experience”—Saisei (regeneration), Saisei (peak condition), and Saisei (uniqueness).
About GO GRANDCLASS Uonuma Koshihikari Edition
This signature sake is brewed from the finest Uonuma-grown Koshihikari rice, cultivated in the snowy mountains of Tsunan. Crafted as a Junmai Daiginjo, it is known for its elegant clarity, refined umami from the rice, and a smooth, polished finish. It has received high acclaim both domestically and internationally.
A New Gifting Option for Health and Joy
The Well-being Set is ideal not only for personal enjoyment but also as a thoughtful gift for loved ones or to mark special occasions. It is a “well-being gift” that supports both a rich lifestyle and wellness.
