See our full sample process →Puresterol® is Bio-Botanica's patented, standardized extract of Pueraria mirifica root. The plant grows only in the rich soils of Thailand's high-altitude rainforests, where it has been used for centuries as a traditional rejuvenator and revitalizer. Bio-Botanica supplies Puresterol® in two formats; this record covers the alcohol-free liquid extract, Part ID 5529.
Puresterol® is protected under U.S. Patent 7,658,955 and is the only patented, specially processed compound of Pueraria mirifica available on the market today. It is standardized to a minimum of 300 mcg of miroestrol per 100 g and a minimum of 20 mg of isoflavonoids per 100 g, so formulators are dosing against a defined specification rather than a variable botanical. The patented process is what distinguishes Puresterol® from generic Pueraria mirifica material, and the specification for each lot is documented on the Spec Sheet/TDS and Certificate of Analysis.
The alcohol-free liquid format is intended for ingestible use — dietary supplement and food and beverage products — and blends readily into liquid supplements, shots and beverage concentrates. Pueraria mirifica is traditionally associated with women's health, framing intended for structure/function positioning only and not a consumer health claim. A powdered format on maltodextrin (Part ID 4523) is available where a dry, capsule- or tablet-ready input is required.
Family-owned since 1972, Bio-Botanica manufactures Puresterol® at its FDA-inspected cGMP facility in Hauppauge, New York. Every lot passes identity, microbial, USP and heavy-metal testing in our onsite quality lab — HPLC, UPLC-MS/MS, GC/MS, LC/MS and ICP/MS — supported by third-party laboratories. We operate under NSF, cGMP and FSSC 22000 quality systems, and Kosher, Halal and Organic certification is available on request.
Puresterol® is Bio-Botanica's patented, standardized extract made from the root of Pueraria mirifica, a member of the Fabaceae family native to Thailand. This record covers the alcohol-free liquid format, Part ID 5529.
Puresterol® is covered by U.S. Patent 7,658,955. It is the only patented, specially processed compound of Pueraria mirifica available on the market today — which is the practical reason to specify Puresterol® rather than generic Pueraria mirifica extract.
Puresterol® is standardized to a minimum of 300 mcg of miroestrol per 100 g and a minimum of 20 mg of isoflavonoids per 100 g. The figures for your lot are documented on the Spec Sheet/TDS and the accompanying Certificate of Analysis.
No. Part ID 5529 is supplied as an alcohol-free liquid extract. Residual solvent and processing details are documented on the Spec Sheet/TDS and representative COA.
Both are the same patented, standardized extract. Part ID 5529 is an alcohol-free liquid for liquid supplements, shots and beverage concentrates; Part ID 4523 is a powdered extract on maltodextrin for capsules, tablets, powders and dry blends. The choice is a format decision, not a potency one.
This format is intended for ingestible applications — dietary supplements and food and beverage. Pueraria mirifica is traditionally associated with women's health; that is structure/function framing for ingredient positioning only, not a consumer health claim. The traditional uses described are not validated in multiple, well-controlled clinical studies and have not been evaluated by the Food and Drug Administration.
Pueraria mirifica grows only in the rich soils of the high-altitude rainforests of Thailand. Sourcing and country-of-origin details for a given lot are documented on the TDS that accompanies samples.
Puresterol® is sold in bulk to formulators and brands, not as a finished consumer product, in pack sizes of 1 kg, 5 kg, 23 kg, 100 kg, 250 kg and 500 kg. Pricing is provided by formal quote against your chosen pack size and volume. Samples ship with a Spec Sheet/TDS, a representative Certificate of Analysis and a Safety Data Sheet.
