Liposomal Vitamin C
Vitamin C is the most studied vitamin in the world — and the most fragile. Heat, light, oxygen and stomach acid all degrade it before it can reach the bloodstream, which is why liposomal delivery has become the gold standard in modern formulations. Yotsuba Japan's Lyposomal Vitamin C uses Zeal Technology™, a patented powder-form liposomal system, combined with green tea catechin EGCg, BioPerine® black pepper extract, and vitamin D — which contributes to the normal function of the immune system.

THE QUIET PROBLEM WITH ORDINARY VITAMIN C
Ascorbic acid is water-soluble, fragile, and absorbed through a saturable transporter — beyond a certain oral dose, most of what you swallow is simply excreted. Liposomal delivery was developed to address this: the vitamin is encapsulated inside microscopic phospholipid spheres that protect it through the stomach and improve uptake further down the digestive tract.
ZEAL TECHNOLOGY™ — LIPOSOMES IN POWDER FORM
Conventional liposomal vitamin C is almost always a liquid suspension: unstable, hard to dose, difficult to carry. Zeal Technology™ solves this with natural carriers and a spray-drying process that converts the liposomes into a stable powder retaining the bilayer structure. It can be encapsulated, stored at room temperature and dosed precisely — the world's first powder-form liposomal vitamin C technology of its kind.
THE FULL FORMULATION
Each daily serving (3 capsules) delivers the liposomal vitamin C complex — contributing to the normal function of the immune system, the protection of cells from oxidative stress and the reduction of tiredness and fatigue — alongside green tea leaf (90 mg, providing catechins including EGCg), vitamin D3 (6 µg, contributing to normal immune function and the maintenance of normal bones) and BioPerine® black pepper extract.
A YEAR-ROUND DAILY RITUAL
The capsules are HPMC plant-based, free from animal-derived ingredients and manufactured to Japanese quality standards. Designed to be taken daily, year-round — especially through autumn and winter, when sunlight is limited and immune support matters most.
