Pueraria mirifica (Puresterol®) is a clinically studied botanical extract derived from a tuberous root native to Thailand, traditionally used* to support women’s health, skin vitality, and overall rejuvenation.* Known as the “Fountain of Youth” herb, Pueraria mirifica contains highly active phytoestrogens, including Miroestrol and Deoxymiroestrol—compounds with significantly greater estrogenic activity than soy isoflavones.*

Bio-Botanica’s Puresterol® is a proprietary, patented extract (U.S. Patent #7,658,955), standardized to contain:

• ≥ 3000 mcg/100g Miroestrol phytoestrogen

• ≥ 20 mg/100g Isoflavonoids

This powdered extract is ideal for beauty-from-within supplements and targeted women’s wellness formulations. Puresterol® has been clinically evaluated in two double-blind, placebo-controlled trials, where topical use demonstrated statistically significant reductions in both wrinkle depth and length after 28 days. Additional in vitro data shows Puresterol® may help preserve collagen integrity by inhibiting collagenase activity.*

Whether used in ingestible or topical delivery systems, Puresterol® offers formulators a highly bioactive, plant-based ingredient with proven clinical support and superior standardization.
