Fermented Ginseng

THE TONIC TRADITION, MODERNISED

In East Asian wellness tradition, ginseng isn't a single-ingredient supplement — it's the centrepiece of a tonic blend. Yotsuba Japan's version modernises that tradition in two ways. First, the ginseng itself: roots from the Kumgang region of Korea, grown to full six-year maturity — the benchmark for premium production. It takes around 200 roots to make 1 kg of the concentrated extract used here.

WHY FERMENTATION MATTERS

Traditional ginseng relies on your own gut bacteria to convert its larger ginsenosides into smaller, more absorbable compounds — and gut microbiomes vary enormously. Here the ginseng is pre-fermented with kimchi lactic-acid bacteria, producing a concentrate that already contains the smaller saponin forms, including the compound K and Rg3 metabolites the published research most often discusses.

THE CLASSICAL COMPANIONS

Fermented Japanese black garlic, slow-transformed over weeks at controlled temperature. Ginger koji, where the mould behind miso and sake converts gingerol into warming shogaol. Nine traditional botanicals — gardenia, jujube, spatholobus, safflower, flax, mint, bitter orange, liquorice and ginger — at classical companion doses.

ENERGY AND IMMUNITY, PROPERLY CLAIMED

Zinc yeast and a B-complex with B12 carry the authorised claims: normal energy-yielding metabolism, the reduction of tiredness and fatigue, and the normal function of the immune system. Three capsules daily — a 30-day course for long winters and demanding seasons.
