Red Yeast Rice Extract Grades & Specifications

Six precision-blended Monacolin K concentrations — from 0.2% functional-food grades to 5% pharmaceutical reference standards. Every batch traceable from fermentation cell to finished capsule.

6 standardized grades GMP · ISO 22000 · HACCP Citrinin < 50 ppb
The Catalog

Six grades, one fermentation lineage

Each grade is produced from the same Monascus purpureus strain under controlled solid-state fermentation, then standardized to its target Monacolin K concentration through low-temperature spray drying.

Why our grade system

Consistent chemistry, batch after batch

Standardization is the difference between a commodity rice powder and a reproducible active ingredient. Our four-pillar quality architecture is what holds the line.

Controlled fermentation

Solid-state fermentation in sealed bioreactors with humidity, pH and temperature locked to ±0.3°C tolerance.

HPLC-anchored potency

Every sub-lot quantified against an in-house Monacolin K reference standard; reported on a dry-weight basis with ±0.05% variance.

Low citrinin envelope

Mycotoxin monitored by LC-MS/MS at every release. Standard grades hold below 50 ppb; reference grades below 10 ppb.

Full traceability

From rice cultivar lot number to capsule fill batch — every container carries a scannable lineage record for your QA file.

Application fit

Match the grade to your dosage format

The right concentration depends on delivery format, target daily Monacolin K intake and regional regulatory limits. A rough guide:

01

Fermented rice & functional foods

Use 0.2–0.5% grades as a culinary ingredient — porridge mixes, vinegar blends, traditional condiments where trace bioactivity is welcome but claims are conservative.

02

Capsules & tablets (daily use)

1.0–2.0% grades are the standard for once-daily 600 mg capsules delivering 6–12 mg Monacolin K — the dose range used in most published trials.

03

Softgels & combination formulas

3.0–4.0% concentrates pair well with coenzyme Q10, berberine or policosanol in lipid-support complexes, keeping softgel fill mass under 500 mg.

04

Reference & analytical standards

5.0% crystalline grade is reserved for in-house analytical calibration, third-party lab reference materials and pharmaceutical R&D programs.

Formulator feedback

We switched three of our cardiovascular SKUs to Twin Horse RYR-C20 last year. Potency drift between batches effectively disappeared — our QC rejections dropped to under 0.4%, and the citrinin reports are the cleanest we've received from any supplier in the category.
