Why it's different

Not a generic licorice extract.

KANZOU® is made by Fabric Onishi Co., Ltd. of Fukuoka, Japan. Its active-ingredient content and blend ratio are tuned to each feeding purpose — which the company positions as distinct from a generic licorice extract.

What it is

Documented
100% licorice extract
A single plant input — Glycyrrhiza. Described in the source materials as a natural, plant-derived feed additive, not a synthetic compound.
Glycyrrhizic acid
The named active component, associated in the source materials with liver-function support.
Tuned per purpose
Content and blend ratio adjusted by feeding purpose — four product forms, documented below.
Made in Japan
Raw material imported and processed domestically; every lot tested before shipment.

How it is positioned

Conservative
A feed additive
Used inside an existing ration as a top-dress or mix-in — not a replacement for the ration, and not a veterinary medicine.
Evidence-led
Backed by a 2019 conference embryo study, collaborative calf data, and independent prefectural research — presented as documented findings, not guarantees.
Traceable supply
Raw material sourced outside China, with whole-chain traceability from field to finished extract.
Wide animal range
Dairy and beef cattle, calves, breeding stock, embryo-donor cows, and horses.
02 / Why licorice

Why buyers ask about licorice extract.

The plant, the active compound, and the liver-and-gut mechanism the researchers describe — in three short reads. The framing stays as cautious as the source materials, so you can evaluate it on the evidence.

01 / The plant

Glycyrrhiza. Legume family. Central Asia.

Licorice raw material is sourced from Central Asia and the Eurasian continent — Tajikistan, Kazakhstan, Azerbaijan, and Russia — through a partner described in the source materials as holding the world’s top market share in pharmaceutical-grade licorice extract. Material is imported into Japan and processed domestically.

02 / The active

Glycyrrhizic acid, in concentration.

The active component is glycyrrhizic acid — recognised in the source materials for liver-function support. KANZOU® is 100 % licorice extract, with naturally co-occurring flavonoids in the accessory chemistry. It is a compact concentration designed to blend cleanly into an existing ration.

03 / The mechanism

Through the liver and the gut.

The researchers describe two pathways. Glycyrrhizic acid is associated with liver-function support; in cattle, improved liver function is proposed to promote gluconeogenesis and, through it, productivity. Separately, oral licorice is reported to be associated with an increase in the gut Bacteroides group — an evidence area the studies link to immune function. Both are presented as documented mechanisms, not guaranteed outcomes.

04 / Use cases

Find the use case that fits your operation.

Where the source materials document KANZOU® in use — the relevant form, why buyers ask, and what documentation is available for each. Dosing figures are starting references; full body-weight and life-stage protocols come with the documentation pack.

Use case 01

For calf programs

Why buyers ask: for suckling and growing calves, buyers look at feed intake, body-weight gain (reported as trends), and a gut-microbiome evidence area. Mitsu dissolves into milk replacer through to weaning.

Relevant form
Mitsu · ≈4–5 g/day
Documentation

Request details
Use case 02

For transition cow support

Why buyers ask: around calving the metabolic load on the liver peaks. Fed from 30–60 days before calving through 60–90 days after, formulated to support liver health, with reproduction and somatic-cell-count context.

Relevant form
Homare · ≈10–20 g/day
Documentation
Transition protocol & mechanism notes
Request details
Use case 03

For embryo-donor protocols

Why buyers ask: in superovulation programs the extract is fed for 90 days before scheduled embryo collection — the context of the 2019 IETS study in Japanese Black donor cows, which reported more transferable embryos and a higher quality score.

Relevant form
Powder · 10–15 g/day · 90 days
Documentation

06 / Evidence

The evidence, kept separate and honest.

Buy on the evidence, not the marketing. We separate KANZOU®-context research, independent third-party studies, and partner blended-product references — and describe each result as the source materials do, including where findings are trends rather than statistically significant. Full references come with the documentation pack.

Category 01

KANZOU® / Onishi-context research

Paper · IETS 2019, New Orleans

Embryo production in Japanese Black donor cows.

Presented at the International Embryo Technology Society Annual Meeting (2019). In Japanese Black donor cows fed the licorice extract through a superovulation protocol, the study reported a significantly higher mean number of transferable embryos and a significantly higher mean embryo-quality score than control. Data from Good Embryo Technology / Zen-Noh ET; the mean number of total ova recovered did not differ significantly.

8.113.1 Mean transferable embryos per cow P<0.05
51.2%60.3% Normal / transferable embryo rate
4890 Donor cows (control vs supplemented)

Figures compare the 60–90 day supplementation group with control. The study found no significant difference in the mean number of ova/embryos recovered. Full reference available on request.

Collaborative · Rakuno Gakuen / CRC

Calf growth and intake.

In collaborative data (Rakuno Gakuen University, Dr. Osamu Dochi; CRC Cattle Research Center, Dr. Masateru Koiwa), calves fed KANZOU® tended toward higher body weight at transfer to the growing stage and steadier milk-replacer intake. The authors’ own “tended to” framing is preserved; results were trends, not statistically significant.

Mechanism · Dr. Koiwa

Why liver support matters.

Dr. Koiwa notes that breeding-driven gains in milk yield have outpaced cow body-size growth, raising the metabolic burden on the liver. In that frame, the source materials position licorice as a feed additive formulated to support liver health — a preventive reading, not a treatment claim.

Category 02

Independent third-party studies

Fukui Prefectural Livestock Experiment Station · 2nd–4th reports

A government-laboratory calf-study series.

Across three sequential reports (the latest in Bulletin No. 36, 2023), the Fukui Prefectural Livestock Experiment Station fed KANZOU® / KANZOU® Mitsu to suckling Japanese Black calves. Feed intake and body weight tended to be higher with licorice, and the immune-associated Bacteroides group increased — described consistently as trends rather than statistically significant results. No disease occurred in either group.

0.750.79 Body-weight gain, kg/day trend
≈3.3× Bacteroides increase by 40 days (4th report)
3 Sequential independent reports

Independent prefectural research. Results are reported as trends; the studies note no statistically significant difference. The 4th report’s separate brewer’s-grains finding is a feeding-management result, not a KANZOU® claim.

08 / About

A child site of KANZOU®, by Fabric Onishi.

KANZOU Greenroot Wellness is a child website built around the KANZOU® licorice-extract platform, using KANZOU® product materials and research with permission. The product and the facts behind it belong to KANZOU® by Fabric Onishi Co., Ltd. — a Fukuoka company that has sold feed additives centred on Japanese-made licorice extract since 2011, after a deliberate, slow path to market: convinced of licorice’s value around 2010, it waited until it could guarantee raw-material traceability before commercialising.

Origin

A patient start.

Convinced of licorice’s value around 2010, the company delayed launch until it could establish reliable traceability — then began selling in 2011 and built the KANZOU® series from there.

Place

Made in Japan.

2077-1 Yamaguma, Tachiarai-machi, Mii-gun, Fukuoka 830-1226, Japan. Raw material is imported and processed domestically, with every lot tested before shipment.

Intellectual property

Stated conservatively.

Source materials refer to patent and trademark activity beginning around 2019, including U.S. Patent No. 12,329,797 B2. Exact issue date and claim scope should be verified before being used as a public claim.

09 / Sourcing

Quality, sourcing, and traceability.

Licorice raw material is sourced from Central Asia and the Eurasian continent — not from China — through a partner with joint-venture factories in those regions. It is imported into Japan, processed domestically, and confirmation-tested per lot. Multi-region procurement is described as a way to keep supply continuous if any one region is disrupted.

Questions before you request pricing.

If your question isn’t here, request pricing or documentation and we’ll answer in writing.

A child website built around KANZOU® — the licorice-extract platform from Fabric Onishi Co., Ltd. It presents the KANZOU® product, research, and sourcing using KANZOU® materials with permission. The product and the facts behind it belong to KANZOU® by Fabric Onishi Co., Ltd.

A 100 % natural licorice extract made in Japan by Fabric Onishi Co., Ltd., used as a feed additive for livestock. Its active component is glycyrrhizic acid, and it is formulated to support healthy liver function. It is a feed additive — not a veterinary medicine.

There are four forms: Powder and Granule (general use, not water-soluble), Mitsu (water-soluble, for calves and milk replacer), and Homare (for fattening cattle, dosed at half the rate of the other forms). Dosing is set by animal, stage, and body weight; the full protocols are provided on request.

Raw material is sourced from Central Asia and the Eurasian continent — Tajikistan, Kazakhstan, Azerbaijan, and Russia — through a partner with joint-venture factories there. The source materials describe sourcing outside China to support whole-chain traceability and supply continuity. Material is imported into Japan, processed domestically, and tested per lot.

Three kinds, kept separate: a 2019 IETS conference study on embryo production in Japanese Black donor cows; independent calf studies from the Fukui Prefectural Livestock Experiment Station (reported as trends); and partner blended-product references. Where the studies describe results as trends or non-significant, we say so. Full references are available on request.

No. KANZOU® is a feed additive formulated to support healthy liver function — it is not a medicine and is not presented as treating, preventing, or curing any disease. The historical use of glycyrrhizin in human medicine is included only as scientific background and does not transfer to this product.

Yes. The documentation pack — composition, research references, and dosing protocols by form and life-stage — is sent to a named nutritionist or veterinarian on request. Independent review is welcome.

Yes. Other manufacturers formulate their own products with our licorice extract — for example the partner references shown above. If you are interested in developing a product with licorice extract, please get in touch.
