Why it was created

Japanese fermentation.
A clearer daily balance.

Red koji is rice cultured through a traditional East Asian fermentation process. Here it forms the identity of a compact 30-day formula for cholesterol-conscious wellness routines.

Chitosan is the largest quantified component, supported by pine needle extract, olive leaf extract powder and rice bran extract containing policosanol.

YOTSUBA JAPAN FORMULA STUDY
Red koji is the rice-fermentation ingredient at the centre of the product identity. Chitosan is a separate crab-derived component, accompanied by the declared botanicals. The fermented-rice, chitosan and botanical ingredients form one composition. The evidence section separates ingredient research from finished-product claims. Illustrative ingredient study. Shapes and movement are simplified; product evidence is reviewed separately.

Ingredient evidence library

Evidence, with the
right boundaries.

Important distinctionThe sources below examine different red yeast rice, chitosan or olive-leaf preparations. They are not clinical trials of Yotsuba Red Koji, and the current pack does not declare monacolin K.
Red yeast riceRandomised human study

Low-dose monacolin K red yeast rice

A controlled study evaluated a defined monacolin-K-containing red yeast rice preparation and reported changes in LDL cholesterol. The Yotsuba pack does not declare monacolin K, so the study cannot be used to predict this finished product's effect.

ChitosanRandomised human study

Chitosan and total cholesterol

A placebo-controlled trial reported a mild cholesterol change in women using a different chitosan regimen. The dose and preparation are not equivalent to this formula's 380 mg daily serving.

Olive leaf extractRandomised human study

Eight-week cardiovascular-risk study

A double-blind trial of a specified olive leaf extract did not find a significant change in blood lipids versus placebo. This is useful boundary evidence and does not test the complete Yotsuba formula.

Red yeast rice + chitosanRandomised human pilot study

A combination containing both ingredients

A 12-week placebo-controlled pilot reported lipid changes with a different formulation containing monacolin-K-standardised red yeast rice and chitosan, together with berberine and CoQ10. It does not test this Yotsuba formula, and the result cannot be attributed to the red yeast rice–chitosan pair alone.

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.

02Is monacolin K declared?+

No. The current packaging declares 120 mg of red koji powder per daily serving but does not state a monacolin K quantity. A monacolin content or effect should not be inferred without product-specific analytical data.

03What allergens are declared?+

The formula contains crab-derived chitosan. The HPMC capsule shell is plant-derived and gelatin-free, but the finished product is not vegetarian or vegan because of the chitosan source.

04Can it be combined with cholesterol medication?+

Suitability should be reviewed by a qualified healthcare professional, particularly for people using lipid-lowering medicines, during pregnancy or breastfeeding, or while under medical treatment.

05Are the cited studies trials of the finished product?+

No. They concern different red yeast rice, chitosan or olive-leaf preparations and do not establish an outcome for this complete formula.
