Why it was created
A familiar nutrient.
A more considered format.
Vitamin C is water-soluble and widely used in daily nutrition. This formula places it inside a powdered phospholipid-led liposomal concept designed for a compact capsule routine.
Green tea catechin EGCg, BioPerine® black pepper extract and vitamin D create a measured four-part active system rather than a single-ingredient vitamin capsule.

Important distinctionThe sources below concern nutrients, green-tea catechin safety or a different liposomal vitamin C preparation. They are not clinical trials of the complete Yotsuba formula.
Vitamin CAuthoritative nutrient review
Antioxidant and immune-function roles
The NIH nutrient review describes vitamin C as an antioxidant and a nutrient involved in normal immune function and collagen synthesis. It does not evaluate this finished product.
Liposomal vitamin CRandomised crossover study
A human pharmacokinetic comparison
A single-dose study compared one characterised liposomal vitamin C preparation with a non-liposomal form and reported higher measured bioavailability. Its formulation is not established as equivalent to this product.
Green tea catechinsSafety assessment
Catechin safety needs dose context
EFSA reviewed the safety of green-tea catechins in supplements and highlighted dose-dependent considerations. This page reports the product’s verified 90 mg EGCg daily amount without extending it into a treatment claim.
Vitamin DAuthoritative nutrient review
A measured micronutrient layer
The NIH nutrient review summarises vitamin D’s established physiological roles and intake considerations. It does not establish an additional outcome for this complete formula.

Frequently asked
Clear answers,
without overclaiming.
01What is the daily serving?+
The current Japanese directions indicate three capsules daily with water or warm water. Follow the approved destination-market label.
02How much vitamin C is provided?+
The verified three-capsule daily serving contains 600 mg of liposomal vitamin C.
03What does “liposomal” mean here?+
The current packaging presents vitamin C in a phospholipid-based powdered liposomal system. The animation on this page is conceptual and does not reproduce the proprietary manufacturing process.
04What other actives are quantified?+
The daily serving also declares 90 mg of green tea catechin EGCg, 5 mg of BioPerine® black pepper extract and 6 μg of vitamin D.
05Is the capsule vegan?+
The current packaging identifies the product as vegan and the composition uses HPMC rather than gelatin. The approved destination-market label remains authoritative.
06Are the cited studies trials of this finished product?+
No. The evidence concerns nutrients, ingredient safety or a different liposomal vitamin C preparation. It explains the scientific rationale, not a guaranteed outcome of this formula.
